When I turned on my laptop It didn't do anything, there was a black screen and the keyboard was red as usual. I left it like this for like an hour and nothing happened. I had to turn it off on the power button

Is it new from the box? If so.. Swap for a new one. Sounds like a lemon.


Otherwise provide more information.

Mine started doing the same thing yesterday. It has happened a couple of times now and is usually fixed by a couple of reboots (holding power button down). I have no idea what's behind this. There have been no added hardware or software on mine for a couple of weeks now. I might reinstall it and see if that helps but if not I'll be contacting Asus for warranty options. Mine is also around the 3 week mark in age.

The only thing I can say for sure is it doesn't happen if I power it off properly from Windows. I'm fairly certain it's not a hardware issue but seems to have to do with hibernation. A driver not waking up properly perhaps? I've not tried disabling it yet but there's an idea for you op.

Same problem here. got mine for a week now, and the problem started.
Few reboots are needed to solve this problem though

Same here seems like the g750 series is unreliable.Im gonna go to the shop where i bought and demand my money back.Im thinking either i want a new laptop and compensation, punitive damages and all that.Or my money back plus punitive damages, there's to many threads on the net about problems with asus laptops i dont really trust asus anymore.

Guys, there are several Black Screen modes created by Microsoft Updates since August, Sept, Nov, Dec. It is sad to see all of this going on, and there are several causes / solutions.

The best you can do is to back up all of your stuff and do an F9 OS reset and hope Microsoft doesn't shoot itself in the foot again :)

This isn't Asus fault, and Asus aren't set up to do Windows debugging for users, so it is best to work it out yourselves by doing an F9 OS reset before calling Asus to see if that restores normal operation - as that is what Asus will ask you to do before approving RMA.

If you get an ok boot occasionally and can get in to the OS to debug, then here is a long list of debugging / solution URL's

https://www.google.com/search?q=windows+8.1+black+screen+on+boot&ie=utf-8&oe=utf-8

Please try the F9 reset, or the debugging / fix solutions - try to pick one that times with your failure - Nov/Dec ones are more likely by now.

If the F9 OS reset works, then be sure and turn off Windows Updates for right now, and do Updates manually, being careful to note which ones you have done if the problem comes back - as you will want to make that update Hidden so it doesn't install again - the list of solution/fix sites will list KB updates known to cause the problem so don't install those.

And, please come back and let us know how it works out :)

Are you sure its because of the windows updates ? I have a desktop pc and 2 laptops but only my asus bricked.

CocoNutty, there are lots of reports from non-Asus users affected. There might be a sequence of events/updates that contribute that doesn't affect everyone. There have been postings from ROG laptop owners about this since August, and they fixed the problem like the rest of those non-ROG afflicted PC owners.

I haven't had the problem, because I don't auto install Microsoft Updates - I do it manually allowing only those I know haven't been causing problems - it is time consuming, but the only way to be sure.

There are situations where a hardware failure can be the cause of similar symptoms, that is why it is so frustrating, but fortunately most/all have been solved by removing the most recent KB's installed, or doing an F9 OS reset.

It would be more frustrating to return a perfectly good laptop just because of a bad Windows Update.

Try the most recent Google solutions for Microsoft updates causing Black Screen, and see if you can get out of the situation that way first.

Be sure to have the network disabled when doing the restore so that the bad updates don't reinstall, turn off Microsoft Automatic Updates and do them manually yourself after checking for problems with each update, at least until this recent series of bad updates from Microsoft stops.

Ok thanks for the tip will try.

This isn't Asus fault, and Asus aren't set up to do Windows debugging for users, so it is best to work it out yourselves but doing an F9 OS reset - as that is what Asus will tell you to do first thing

When i called the customer service the first thing i heard was wait, they dident mention f9 os reset.
Also i noticed a strange peak in my phonebill more then 13 euro for a phonecall that dident amount to nothing.
I wanna like asus they create some nice looking high spec laptops but if they dont work : (

Wow so many issues with these models it kinda made my mind up to actually return it to the reseller after holydays :/
Not sure how it will work from there forward, if i'l get my moneys back or if I'l be able to ask for a replacement.

Hello , I have had the problem of black screen the same day I received the PC. I turned on the computer for the first time , started the configuration of windows and crashed. I had to forcibly shut down the pc and then you are no longer on again. Problem: black screen , all the LEDs on except the processor, after 30 seconds the fans run indefinitely . After several attempts , turning on and off , the PC is started , I did the updates of windows update and these days I was not given more problems , I think I've also updated the video card driver . Occasionally, however, the computer takes too much to go off or after I put the windows password is not accessed . I asked for a refund because where I bought it is no longer available and I want to buy it back at another site to 200 € more than what I paid , but I'm afraid I have the same problem . I sent an email to asus in which I explained the problem and they responded with a short sentence : " it is a hardware problem , replace the PC ." I was not given any explanation , bad service . I believe that even they know what the problem is due . Are undecided whether to let me replace because the problem is not me giving more , but I think of the money I spent and the pc has given me from the start. We can have a definite answer on the issue by this company ? I think I 'll buy another laptop of another brand . I used google translate.

Hi everyone,

same problem here: when i resume from sleep, the screen is sometimes black, and requires re-sleeping and waking up to get the image to appear.

Backlight turns on, everything works (sounds, logging in etc), so the only problem is that the image is not appearing on the screen.

It could of course be a driver/windows issue, but if this keeps continuing there's not much else to do except to return the laptop.

Has anyone tested what happens when an external monitor is connected? does the image appear on the external display or does everything stay black?

CocoNutty, I didn't mean literally the first thing.

I corrected the wording to fix the point I was making:

"...so it is best to work it out yourselves by doing an F9 OS reset before calling Asus to see if that restores normal operation - as that is what Asus will ask you to do before approving RMA."

This happens on my non-RoS laptop too (X550LB) on different occasions. I have already done an O/S reset (Win 8.1) twice in the 10 months it is in my possession. I experience this most often than not every time my system auto-installs an update or install an old game like "Bioshock" with a very old .net and DirectX driver set (Steam's fault for selling games so cheap over the holidays!) Learned the hard way and am now managing my updates.

Another pain in the butt is the pro-active update install system of McAfee that pretty much checks your system and dl's / installs updates on your apps and O/S every so often which I believe also conflicts with Windows' built-in update list, so installs get in conflict with one another. BTW, switched off the McAfee thing - what a pain.

Still waiting for my G751JT though but am expecting the same if I don't manage the Windows update installs like I do now with my non-RoS.

I guess it's not a windows update issue,cause i have 3 pc which is running win 8.1 with all updates installed and only the g751jy doing this issue. I need to hold the power button and reboot to get it working. It is totally random sometimes boot,sometimes not. First when i got my rog it went dead after 8days,the whole mobo died,no boot at all. The pc shutdown itself after 3 seconds. I didnt have any replacement option so i sent it to RMA. I had to wait nearly a month to replace the mobo. In the first 8 days it didnt do this. Now, it started to do the same as mentioned above. It is frikin annoying cause i had to wait nearly a month to get it "fixed" and now it's a sometimes work,sometimes not machine. What should i do? Cause i really dont want to send it on RMA again beacuse it's frikin slow and crap.
Sorry for my bad english.

Sunny I am fairly sure its a Driver or Bios Issue, I would wait for a driver update to fix it. I do hope ASUS is taking notice of this issue, for me its not a deal breaker, but an annoyance.

I updated to bios 205. Still the same. Black screen on startup sometimes. Is there any way to downgrade to bios 204?I want to try it too. I tried a lot of drivers.Chipset,audio,vga.etc.Nothing worked. It's causing this issue after it came back from RMA. And finally,the vga got coil whine cause i can hear a really annoying buzzing noise when the gpu is on load. It's sad but this machine is a crap for this price. It has got 5 times more problems than my 2 years old acer notebook. I would really appreciate a WORKING bios update and drivers as you mentioned. This machine drives me crazy.

I have the exact same problem on my G751-JY. It has become more frequent lately. I'm running latest NVIDIA beta drivers and bios 205 (latest for JY). Now I might need 4-5 sleep/wake cycles to bring up the image on screen, before it used to be just 1-2.

Also, sometimes when booting, the computer gets stuck on the bios POST screen logo and requires a hard reset.

And yes, there's the annoying coil whine on this gpu as well on some games.

I'm quite disappointed, compared to my old G75 this has vastly more problems. Going to take it to service soon.

Has anyone found any kind of resolution for the annoying blank screen problem on their G751?

sunny474
01-04-2015, 03:44 PM
Dunno what's behind it. When i got black screen it doesnt even post the bios logo. It needs power off and on. I have win 8.1 installed in uefi mode. Cant even try recovery cause it came with FreeDos. And it is totally random. It boots properly for 2 days and sometimes it doesnt boot for twice in a row. And yapp,the coil whine in some games really freaks me out. Especially the older games with higher fps.
i have the 751JY modell too with 256 GB SSD,4710hq and 980m.

Mublur
01-06-2015, 09:09 AM
The problem in my 751JY is that when the screen does not turn on, the computer DOES work: even if the bios logo is not visible, it starts booting windows, and also resuming from sleep with a blank screen works (i can log in, it just does not show anything on the screen).

So, it due to the uefi/post logo problems, it cannot be a windows driver/update issue. It is either bios, vbios or hardware issue. I'm going to return it for service. i'm not going to keep cycling my computer 4-5 times just to get the image back on the screen.

Asus, get your quality control together!

I don't know if this would help you in any way but I've had issues with 2 previous model ASUS laptops where the VGA driver messes with the backlight of the screen - but I understand you think it can't be a driver issue. The only other laptop I've seen this behaviour on was a MSI that also had the GPU soldered on. It would sometimes show an image and sometimes not but would always output to an external screen. it turned out that the core chip was somehow slightly misaligned - aka a quality control issue. But this seems unlikely to me because ASUS have had an excellent track record for build quality for me.

Are you sure the screen is blank and that the backlight is simply not on?

Yeah, just to clarify: the backlight is on, but no image is present. pressing FN+F7 can be used to turn it off and on, but no image appears until power has been cycled multiple times.

Usually this problem appears when the computer has been for sleep overnight or longer times, so perhaps a capacitor issue etc.

Generally I've been happy with ASUS before but it seems that with this unit I got a bad apple (first broken HDD and then this screen problem).

It could also be a Windows sleep issue, along with Black Screen boot issues, there are lots of reports:

I can confirm that this is *NOT* a driver issue, nor an issue with Windows updates or Windows sleep. This is either:

1. BIOS issue
2. Hardware issue

I am certain it has nothing to do with drivers or Windows because it happens before Windows is even accessed. As an example (I'm experiencing the exact same problem on a GL551JM) I can turn the computer on and smash the f2 key to get into BIOS. But, there's nothing on the screen! The backlight is on, but nothing is displayed. I know I'm in BIOS, because I can right arrow four times then hit enter twice and the computer will reboot, which is the sequence to get to the "Save and Quit" prompt in BIOS.

So the real question then: is this hardware related, or BIOS related?

Aeiouy, if you have debugged it to a BIOS issue then you, and others that have the issue, should report it to Asus with the details/steps/debugging they used to demonstrate it - maybe even a video attached to the Technical Inquiry as a zip file. And, ask Asus for an updated BIOS.

https://vip.asus.com/ <== create a login, register your laptop, and file a Technical Inquiry

Also, PM MarshallR@Asus and cl-albert so they are aware of it.

There are also lots of Windows based black screen issues, some caused by Microsoft updates, so make sure you have debugged to which problem it is before reporting it to Asus.

Please let us know how it works out.

Hi everyone,

I had the same problem everyone is describing and with my 751jy i just disabled "quick restart." Apparently Microsoft in its infinite wisdom has decided to incorporate aspects of hibernation in the normal boot sequence. It is even enabled by default!

Off hand I can't remember where to find this because it has been two weeks since I "fixed" this problem. It's in the power management somewhere. Anyway I never get the stupid black-screen-hit-the-power-button-repeatedly blues anymore. Try it. You might like it.

This is definitely a windows issue for me. I see the ROG logo on bootup and then the screen goes black. I have to hold the power button down 5 seconds and power it back on again...over and over until I see windows. This just started happening this morning and I know that my computer restarted last night to apply some windows update. Unfortunately, there were 9 updates last night from microsoft so I'm not sure which one caused it. Most are "Security Update for Windows 8.1 for x64-based Systems), but two are Security update for Internet Explorer Flash Player and Windows Malicious software Removal Tool.

I really like like hard resetting my computer in order to see the screen and it's happening from restarts as well as a cold boot so I need to figure this out.

Updates:

Firm repair attempt: Opened a command prompt windows (CMD) with admin privileges. Ran "sfc /scannow" which took about 5 minutes. The results indicated that it found and repaired corrupt files.

I haven't been able to recreate the black screen issue after several cold starts and restarts by opening and closing the lid. Hopefully the problem is fixed...fingers crossed.

Hi all,
This is my problem which sounds remarkably similar to others in this thread.

Product G751JY-T7051H, 32Gb RAM, 512Gb SSD, 1Tb HDD, 1 year Asus warranty

Problem: Intermittent fault with display.

Description:
Press Power On button. Frequently the machine will not show any display.
The laptop monitor can be seen to turn on, the LCD backlight is lit dimly, but nothing actually displays on the screen.
If I immediately hit F2 to go into BIOS nothing displays, but the machine behaves as if it has gone into the BIOS (LEDs on front of laptop light/flash, etc.)

Hit Power button again and it quickly turns off (ie. it must have entered the BIOS screen as opposed to booting into Windows 8.1 which takes longer to start-up/shutdown).

Note that in Windows I have set the Power button to perform Shutdown (not Hibernate or Sleep).

Another time the machine starts perfectly.
It will show the Republic of Gamers start-up logo, and proceeds to boot into Windows with no problem.

After working with the machine I do a Shutdown (not Sleep or Hibernate).
When I try to turn it on again it may or may not display!

Sometimes I have to power off and power on 2 or 3 times before the display works properly.
I have tried disabling various relevant options in the BIOS to see if something there makes a difference, e.g. Fast Boot, Wake on Lid Open, Power Off Energy Saving, but nothing improves the situation.

This behaviour suggests to me that it is NOT related to Windows 8.1 sleep or hibernate modes in any way because the problem occurs before it has even gone into Windows, i.e. just at the BIOS as explained above. Nor does it appear to be a physical problem, e.g. faulty wire connection in lid, because problem occurs without touching or moving the lid or laptop at all, only pressing the Power or F2 button as described above.

The BIOS that came with the machine is v205 which is the latest currently available on the Asus drivers website.

I have spoken to Asus Support (01442 202700) who confirmed my product registration, talked me through a static discharge routine (disconnect AC adaptor, hold Power button from Off for 30 seconds), and they confirmed from my description that it sounds like a hardware/Bios problem, and gave me a Service No. They suggested I speak to my supplier (SimplyAsus.com) to discuss options available.

You do not need to log into Windows to experience the problem. Just use power button to Shutdown/Power up.

PS. I also tried sfc /scannow as suggested above, but it showed no errors, made no difference.
Cheers
Jim

Hi hmscott,
Thanks for the valuable information. At this point, I'm not sure whether it's the BIOS or a hardware issue, so I have sent it in to Asus as an RMA. My guess is they'll replace the hardware to see if that fixes the issue. Once I get it back, I'll update the thread on whether it seems to be hardware or BIOS related.

Thanks!

I'm back just to update you on my previous post.

I've RMAd my G751JY but because of so many problems associated with this model of laptop reported by customers in this forum and other places I have decided to cut and run. I don't think I want anything to do with Asus now.

My supplier has given me a full refund.

Decided I didn't want to chance having to wait days/weeks for a "repair", only to have the same or another problem turn up!

Also I have learned a lot about Asus customer service being very poor.
I found the following article (2008) which was quite an eye-opener (I suppose in this day and age similar practices may well be used by other major manufacturers!):-

Guys, i have suspecting if it was RAM fault, some G751JT/JY come with 8gb version with a single module RAM. If any experienced user here you can try replace the ram, inside. replace an corsair or any RAM to test. I'm testing with corsair 4GB 1866 x 2 module here and dint found black screen so far. Cmos bug also can cause this but not sure, The cmos they use are out of date! instruction set are too old which has higher failure rate compared to G750. and i noticed the bios older than when i first purchase my asus gaming notebook back in 2012.

Well well - not a W8.1 fault after all! I sent it for repairs and they changed the whole Mobo. No blank screens and hiccups anymore! It's a great thing that in finland you can just throw the computer back to the reseller and they have to repair it for free within its normal lifespan. so, if you're having strange Win8 corruption (like I had) and blank screens or BIOS hangs, check it under warranty

When debugging these days it is tough to know if it is Windows at fault or the Hardware, when the symptoms are the same, and there are so many Windows Black screen causes/solutions across many different systems independent of hardware faults, so I am glad to hear it is solved for you now :)

Now you can enjoy your system!

I was able to fix this problem on mine. This what I did. Press f9 on start up go to trouble shooting go to advanced and click the option restart with fix or diagnosis something like that, the one that repairs anything wrong on start up. Then when you finally log on go to your driver manager setting find your display adapter mine was the 970m GeForce right click it go to properties then disable it then re enable it. Shut down your laptop press f9 again choose option as stated above and you shouldn't have the problem anymore. I'll update this if it happens to me again.

I have the sme problem as everyone else no screen on startup. I disabled windows update and it laste a week before reappearing. To Boot I have to plug in an HDMI device so i can debug. WHen I check video drivers they are a generic driver not the Nvidea. Doing a windows diagnostic returns a hardaware change detected error which when you go to advanced resets the video driver and corrects the problem. For me it appears to be a hard ware issue with a loose video card or processor or a bad joint which is causing intermittent issues. I am very dissapointed with the reaction on here from Admins pretty well telling customers you are on your own, it is appalling on a high end system that ASUS appears to be doing absolutely nothing to identify or rectify this fault and at the very least advise their customers what to try to fix it. Unfortunately I have to go overseas for two weeks but when I return I will be taking the issue up with Australian consumer affairs. This is clearly a product issue where multiple customers complain of the same issue. If this was a car there would be a recall.

Well tonight exprinced the same failure again just before I go out of country for three weeks. Still works through hdmi port but screen totally dead windows troubleshooter still reporting an undetected hardware change so for me it would appear to definitely be a hardware issue.

I have reset to factory and will be returning to the retailer for a replacement. If I get the same issue on the new one I will never buy asus again and will be using social media to let everyone know about this issue. I suggest everyone e here do the same to get some action on this issue.

It's a static issue. Press and hold the power button for 45 seconds (laptop will turn off), this does a power drain and when you turn your laptop back on, it should work correctly. It's happened to me several times, and this works everytime. Very annoying, not sure what causes it, but it seems to work. Hope this helps.

I'm sure it is not windows problem. I have had 8 pieces from this laptop.Two of them has been the same problem.Only way to fix it change the motherboard.The other 6pieces never had this kind of problem.They had other:))That is Asus fault.

Just wanted to share my solution to the problem, Im an owner of G751JT. For me the problem went away when I removed the Hibernation-file. Note that the problem only appeared to me when I did put the computer in to hibernation.

Just start the cmd.exe as an administrator and type the following command "powercfg.exe -h off". This will delete hiberfile.sys and uses sleep mode instead, not using the same settings for hibernation.

After doing this I never had the problem after putting the computer to sleep or "hibernate". It will free up about 8Gb of space on the C-drive as well as it removes the file. Nice if you have a 128Gb SSD.

(Note that my first language is swedish and not english if there are any problems with the grammars)

Just wanted to post that Nvidia does mention this problem in their latest driver doc. (For tiled displays though).

"[347.09, GM204]: Blank screen observed on an ASUS Tiled display when system
resumes from shutdown or hibernation with Fast boot option enabled from BIOS. "

Right click the start button, then click on the command prompt with admin, then type:

powercfg -h off

Reboot, then report if problem persists. My g751jt is running perfect with auto updates. That command turns off hibernation and deletes the hiberfil.sys which takes the same amount of data as your ram capacity, you will save up ssd space.

It's not asus fault that the windows defaults to hibernation on laptops, it's microsoft. So if you have not turned off hibernation, you are not actually shutting down your pc, it goes to hibernate mode.

That's probably why your laptop returns to life only after power cycling, what actually happening is that when you think that you turned off your laptop, it only goes to hibernate mode, so when you power it up it freezes, when you power cycle it it will be forced to restart and exit hibernate mode and goes to normal operation, until you turn it off again and go hibernate.

TLDR: TURN OFF HIBERNATION MODE!

Hello everyone!!!
i noticed from the beginning some strange behavior from the G751JT, but only with black screen. I used some suggestion with the hibernation file off and i could not start my system and could not enter the bios. I was in trouble. After a while I removed two Disks one is SSD and one is Hybrid HDD and finely i got in to the BIOS and i setup all to defaults. Than i put disks into the Laptop and since than I have no problem.
I'm pretty shore that this issue is to do with BIOS and Disks. Try To Remove all disks and start the LAPTOP, and set all to defaults, and than put Disks again. Good Luck.
Update:
This cause is from hybrid 1GB hdd, disable any option boot option from this disk in bios. I test it again.
Update:
It seems to be an issue of boot conflict or something.
As long as it is only one Boot Option Priorities: Windows Manager than everything is fine. Check this in bios.
In Boot configuration
Launch CSM Enable
Launch PXE OpROM Policy Enable
than only one option should be enable

Finely i think i got it. Please setup all power buttons to sleep. It meens set all Power Management plans to defaults. It should help.
In bios set power lid open and Power save enable.

Originally when I first got my G751 I didn't have this issue but it started to do it now and then, but it started to get more frequent and today it got to the annoying point. So I did the following things in the following order after reading here and doing a little Google'ing just to cover it being a windows and not a Asus issue

1. Downloaded and installed the latest driver for my 980m (353.06-notebook-win8-win7-64bit-international-whql)
2. Turned off automatic windows downloads and installs to automatic downloads but user install
3. Went to my power options Control Panel > Hardware and Sound > Power Options and clicked on "Choose what the power buttons do" made sure all the buttons only slept the machine and also I Disabled "Turn on fast startup (recommended)"
4. In a admin CMD powering -h off

So far I have rebooted and turned off and on the machine a dozen or so times and yes it does take a lot longer to shut down and just as long to turn back on, but I am getting the ROG loader screen and the spinning dots of loading up now but it loads directly to desktop, I'm hoping this does the trick as I am little scared/unsure how to do a bios update.

Will update this if things does come back to haunt me

I have the same issue.
Newest BIOS 208 for my G751JT was flashed.
"Fast boot" option in BIOS is disabled
Hibernation in windows is off
I can reproduce the black screen by

1. hard reset the Laptop by long pressing the power button after running windows for a longer period
2. change and save something in the BIOS

This issue seems to persist.
I got a brand new G751JT from the store. First day out of the box, after windows 8.1 update to latest version I noticed the black screen sometimes.
Sometimes it works ok, sometimes I get a black screen when switching on or waking up.
In case of the black screen I always need to power off and on again, then the login screen appears.
The black screen occurs both after shutting down and also hibernation.

I found this thread and tried most of the suggested options.

Switched Windows Updates off and made sure all buttons are set to hibernate. Still black screen sometimes
Updated NVIDIA driver. Black screen sometimes
Updated BIOS to 209. Still black screen sometimes
Started CMD as admin, entered powercfg -h off. No changes, still black screen sometimes
Finally I reset the Systen and put it back to initial settings. Same black screens...

I thought about Updating to windows 10 and solving the issue that way but I found this thread:
https://rog.asus.com/forum/showthread.php?73687-Windows-10-upgrade-now-just-black-screen
and didn't even feel like bothering.

I will send the laptop back to the dealer and look for different options.
Had a DELL laptop for 5 years with Windows 7 and no issues up to now.
I am quite disappointed because of the otherwise good reviews of this computer.
I wonder if its a Motherboard or other hardware issue. If it was really Windows, then every G751JT should show the same behaviour.

Good luck to everybody facing black screens...

Disabling secure boot seemed to resolve the problem for me. (In BIOS)
Also disabling fast boot. (In Windows)

I had the issue before this too but it seems to be fixed after upgrading to the newest BIOS (v210)

Hi all,

I have troubleshot this over and over. It is one of the most annoying problems I have ever seen in a computer in my entire life! I have tried everything and everything seems to work---for awhile!

The only thing I can say is that things have gradually gotten better in the last year. The 210 bios update was a huge improvement. Windows 10 was also a biggie. I think it is some kind of a power issue for sure. I can make my G751JY black screen anytime I want to. All I have to do is 1) move it or 2) power it up on battery instead of on the adapter. My 2 cents.

The system is running, just no display. I have tried several things in order to get it to "wake up" the display. I also set power button to "turn off" to make exiting windows more graceful.
I can press enter and input password (from black screen) and hit the steam button. The startup sound from steam splash screen plays thus confirming system is running.
Things I have tried:
Closing/opening lid (seldom works)
Power OFF, close/open lid and power ON (sometimes works)
Press Sleep (Fn+F1) & wake-up with power button (works better)

No perfect solution, I just turned off fast boot and hibernation, if problem persists I will try enabling legacy boot. :confused:
