Hi, as the title reads I've been having trouble with my G750JW booting up. I have no idea what the problem might be. The computer receives power, and the lights are all flashing, the only peculiar feature is that the drive activity indicator and the wireless indicator are blinking intermittently and in a clear pattern. Sort of like: 1..2......1..2.......1..2......, where 1 is the drive indicator and 2 the wireless indicator.

Previously the computer randomly turned on after a certain amount of time, 3-5 minutes after pushing the power button and a sharp sound came from the harddrive (which always happens at that point), if I was lucky (1 in a 30 chance I estimate) the computer would proceed to the boot screen. If the computer hasn't booted by that point, when the "sharp" sound comes from the hard drive, I know that it won't boot, no matter how long it's been on for.

Now, I guess my luck has ran out, as it won't boot anymore, after a few days of attempts.

I'd love to know what the pattern of the indicators could possibly mean, as there's no info on that in the troubleshooting manual.

Feel very hot air come out of the fans?

been met with a terrible fate?

Use the wrong power charger?

Use the compy in a humid area?

I haven't done anything out of the ordinary. The computer works fine even with this issue (when it ocassionally turns on), I just can't shut it off, then the booting issue becomes a problem again. Thank god for sleep mode, however, this time I forgot to plug it in and it must've shut down during the night. And no, I haven't been travelling around with it in sleep mode.

There's no problem with heat, it's not slow, there's nothing out of the ordinary. It's performance is the same as the day I bought it.

Thanks for your help.

Mulhollands, if you haven't updated drivers, this sounds like the Bluetooth driver bug that messed up boot/shutdown.

If you disable Bluetooth, and power off / power on, does the problem stop?

39030

If that does/doesn't do it, try doing the Windows 8.0 updates, then download the latest Windows 8.1 drivers (they should install on Windows 8 too), and see if that fixes it.

Then try upgrading to Windows 8.1, and do all the Microsoft Windows 8.1 updates - and double check the driver versions to make sure the Windows 8.1 upgrade didn't downgrade some of the drivers you updated before the upgrade.

If it isn't any of those, it might be a hardware problem, and all that above has given you a good base to report in a Technical Inquiry to Asus for an RMA.

Here are the Windows 8.1 driver update links:

I'm currently trying what Darnassus recommended, "Try take battery out and leave unit without power for a day, then try turn it on", but what you're saying sounds very plausible. Hopefully I can boot it up and attempt to disable it.

Then try upgrading to Windows 8.1, and do all the Microsoft Windows 8.1 updates - and double check the driver versions to make sure the Windows 8.1 upgrade didn't downgrade some of the drivers you updated before the upgrade.

The computer is already upgraded to 8.1 with all of the available windows updates (even the optional ones) as of the 15th of July, and the driver versions I'll be sure to check once I manage to turn the computer on.


If it isn't any of those, it might be a hardware problem, and all that above has given you a good base to report in a Technical Inquiry to Asus for an RMA.

Hopefully that won't be necessary :p I have a good feeling about the bluetooth thing. I'm quite sure I haven't ever updated the bluetooth drivers, since I don't even use bluetooth. If only I had bothered to turn it off.

Thank you for the links and the help!

Also, the pattern of the flashing lights are 2..1......2..1.......2..1......, where 1 is the drive indicator and 2 the wireless/bluetooth indicator, and not the other way around as I wrote in my original post. Which makes it even more plausible that it's the bluetooth acting up.

Mulhollands, the bluetooth bug was when using older BT drivers, downloaded from the JW download area, instead of the newer ones available in the JM/JS/JZ - or BT area listed above. What version driver are you running?

I can't be sure if I ever updated the BT driver from the factory default, but if I did, I definately downloaded it from the JW area. That's where I got all of my driver updates from. I can't check what version yet. 5-6 hours left until the computer has been without a battery for 24 hours. I'll attempt to get it working again and I'll update you on that information later.

Mulhollands, you can check what driver you have in the Programs and Settings Control panel, then find the same named newer version drivers in the JM/JS/JZ or general/central repositories for drivers.

Asus has a tradition of not updating drivers for products once the new versions/models come out, so you need to figure out what new products use the same hardware components in your model and hunt down the latest version. Especially for Windows 8.1, bugs were/are still being fixed and improvements made, so the drivers in the JW/JX/JH areas that haven't been updated much since release are out of date.

Have fun :)

I just plugged the battery back in and I can confirm that leaving the computer powerless for 24 hours made no difference whatsoever. Also, after having thought about the driver thing, I doubt that's the problem seeing that the computer fails to boot even up to the point of drivers being loaded. There's nothing but a black screen, the power button, the power indicator and the number lock indicator glowing (as well as the battery charge indicator (dependent on if I have the power cord connected or not (as it should be)), and the drive indicator and wireless/bluetooth indicator flashing in the aforementioned pattern.

Connected USB devices do receive power (tried with a phone and a chill pad), so at least it still works as a pretty large phone charger. The fans are blowing at idle rates, the external temperature of the case and the air from the fans are at "idle"-temperatures. However, the other day when I left it on for 20 minutes, just to see if it would start by itself, the fans began spinning really fast and it got quite loud, but I'd say that the temperatures of the case and the air was the same, if not even a bit cooler due to the increased fan speed. I just turned it off and have been unable to replicate that behavior.

There's no sound coming from the mechanical harddrive (the only harddrive) to indicate that there's any activity. If there was, I'm sure the drive indicator would function normally.

I don't know if there's anything else I can do to troubleshoot, but if anyone got any ideas, I'd greatly appreciate it.

Did you end up getting your machine to boot? Mine has just developed the exact same issue. Worst case for me is I am 6 weeks out of warranty.

If there is nothing at all on the screen, as in not even the post boot messages, then you might have a burned GPU (happened to me a couple times on my older ROG G1S).
If you do see the boot logos but it doesn't load into windows, you should try what hmscott is proposing. Remember Win8.1 and Win8 are two different OS (the naming is misleading), therefore drivers could be causing an issue. Try to log onto safemode

Hi,
It's windows 8.1, and just did an update, which is why I needed to restart (otherwise I never restart, just power off which I guess is just hibernating).

It's showing nothing on screen - no ROG logo etc. Hdd led and wifi led flash (and the DVD's led), then it either shuts down or just sits there with the leds flashing.

Tried taking battery and power out, and holding power button for 60 seconds. That makes it take maybe an extra second before the leds start flashing in the 1,2... 1,2... sequence again.
Can't get a bios screen or boot in safe mode. Even with hard drive removed it did same boot sequence. Not even a beep etc that no hard drive detected.

The reason I bought this is my G1 lasted so long! It literally died about 2 weeks ago, and was nearly 6 years old. (been using it as a media player). The g750 is 13 months old, so I'm gutted if it's gonna cost me to get this fixed.

Sorry for digging this up but did you ever find a solution, mine just did the exact same thing after a windows update, same light flashes, no POST

I got for repair g750jw with same issue no boot only wifi and hdd indicators flashing. It has a cpu power line shorted. If to say correct the 12v of cpu power line was shorted. I find that there where 1 dead transistor and 3 dead capacitors because they received too much power. Also the cpu and gpu fans where spinning but there was no keyboard light. I think you should send it to repair because it's can be a hardware problem if laptop don't want to boot even when hdd is out so Bluetooth cant interrupt boot priority.
