Hello everyone, I bought my G53 last year, and had problems with its keyboard since then. It has the latest BIOS, lates ATK, latest everything, but still whenever I type it drops keystrokes and I can't type properly or even game for that matter, should I send it back for them to change the keyboard for a new one or is there something I'm missing? Last time I sent it there they told me it was because the keyboard was backlit, what made it harder to type on, which I think is wrong.

What a crock!! Can you believe those guys? Where do they find 'em?

Aside from updating the BIOS and ATK Package, here are some additional things you could try to eliminate missed keystrokes:

1) Eliminate DPC Latency. Install Atheros Wireless Network Adapter driver version 9.2.1.432 or later if you have that WiFi card. The stock driver has BAD DPC Latency. Consider installing DPC Latency Checker. There may be other drivers on your system contributing to latency which will cause keyboard lag and possibly missed keystrokes.

2) Configure your Browser to use software rendering instead of GPU rendering. It may help when you are typing in a Browser window.

3) In Keyboard Properties, reduce "Repeat delay:" by moving the slider all the way to the right towards "Short". Then increase "Repeat rate:" also be moving the slider to the right towards "Fast" to the point where you start typing inadvertent double characters. Then back it off a scosh, so you only type double characters if you mean to...

If that doesn't do the trick, you may have an actual hardware issue. See http://rog.asus.com/forum/showthread.php?9245-Cause-of-unresponsive-sluggish-keys-on-G74

Well I sent it to the guys who sold me, who actually are resellers, so they're not from asus itself. Still it was not nice of them.

Thank you for the quick and complete response, I'll look into all that!

EDIT: Hmm, I started using DPC Latency Checker. At first it was fine, but then it went up and I got this message: "Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc."

Yep - that is how you troubleshoot with the utility. How high (what color) and frequent are the spikes?

Are you running the ASUS Factory OS with Bloatware or a clean Windows 7 install?

What did you do about your keyboard problem in the end? I've just recently got my laptop back from having the whole not powering on because of shielding problem... Now I seem to be getting keyboard problems. And the other night I thought my laptop had crashed only to find that if I plugged in an external keyboard and mouse it was just that the touchpad & keyboard had stopped working..

Time to RMA again!? I'm seriously looking forward to selling this laptop and it's only 3months old :(

I have same problem.
I did a lot of research about this topic.
Found out that it's problem with synaptics touchpad driver.
If you uninstall snaptics touchpad driver, keyboard works fine. BUT you cannot disable touchpad while typing without synaptics driver.
So annoying!
I decided to live this this keystroke skipping issue...... i hope asus release new bios or something...
BTW, if you disable touchpad from your bios option, the touchpad is disabled while you are typing, but need to restart and go to bios settings again to enable touchpad.....

If you're not on the run with the laptop, then the touchpad will be turned off when you connect a external mouse on the notebook. Not sure if you have that issue...

But which driver have you tried for the synaptics touchpad since you say that you can not disable it?

Interesting... I'll try another version of the touchpad drivers tonight. In regards to BIOS updates, heh I won't hold my breath it seems to far ASUS have moved on from this laptop and don't seem to update anything in regards to drivers or BIOS updates :)

As I said before I can't wait to sell this once I've moved countries so I can build my own desktop and if I have problems simply replace the parts :)

Be sure to install the right touchpad drivers! ;) I'm not sure if that notbook is like the G74 with either Synaptics or Syntellic drivers.
I installed Synaptics 15.3.17.0 from this thread (http://rog.asus.com/forum/showthread.php?5224-Drivers-Apps-and-How-to-s&country=&status=) and it wokrs perfect after yesterday when the touchpad went crazy without disabling (when connected with external mouse) and the FN-key didn't work :P

Heh just went and checked on ASUS Support site... only have one set of drivers I can try... guess I'm not going to have any luck rolling back to another version :) Perhaps the buyer won't pick up on the fault :P

Wonder if I should just go directly to the source and download from Synaptics website?

Don't download that driver for Asus Support, it's old :P Try the version I installed:



Touchpad

Sentelic Touchpad 9.1.3.5 (http://dlcdnet.asus.com/pub/ASUS/nb/Drivers/Touchpad/vista/Touchpad_Sentelic_Win7_64_Z9135.zip) - Recommended
Sentelic Touchpad 9.1.7.7 (http://dlcdnet.asus.com/pub/ASUS/nb/Drivers/Touchpad/Touchpad_Sentelic_Win7_64_Z9177.zip)

Synaptics 15.3.17.0 (http://dlcdnet.asus.com/pub/ASUS/nb/Drivers/Touchpad/Synaptics/Touchpad_Synaptics_Win7_64_Z153170.zip) - from Asus FTP (excruciatingly slow)
Synaptics Scrybe Driver v 15.2.20 (http://drivers.synaptics.com/Synaptics_v15_2_20_C_XP64_Vista64_Win7-64_Signed_Marketing_SGS94_UI-Scrybe.exe) - from Synaptics

EDIT:
Or download the latest driver from synaptics home site, that's up to you :)
I hope the issue you have gets fixed by updating the touchpad driver :)

I tried many versions of synaptics driver but none of them fixed the problem
i don't think i tried 15.3.17, so i should give it a shot.

Hello everyone, sorry about taking so long to reply. Attached is an img of the latency checker.

So the probable cause of the problem is my touchpad driver? Since I don't ever use it, should i just uninstall the driver and the keyboard will start working normally?

EDIT: whoa just got a peak of 16000μs when disconnecting everything (usb's, HDMI adapter, LAN cable, power) to test out the keyboard itself. Should that happen or does it say more about the problems I have?

Also, after doing it reconnecting the mouse, it is spiking on and off in short time windows, making it impossible to use without feeling like smashing something.

The cause of your DPC Latency is unknown until you disable a driver in Device Manager and the latency peaks are reduced or eliminated.

If you are using a USB mouse, it is important to disable the touchpad. This may be done by a) configuring the touchpad to disable on detection of a USB Mouse, b) from the keyboard (Fn-F7), or more permanently, c) in the BIOS.

If you have a Sentelic touchpad, and want to disable it to run a Mouse, it is important to run the 9.1.7.7 version driver. Earlier versions have an issue with the touchpad re-enabling itself when a mouse is used. In addition, there is an issue where disabling the touchpad in the BIOS also disables the keyboard.

Latency spikes caused by removing or installing hardware, or loading programs are not problems.

Do you suggest any good way to find out what driver it could be? The peaks are quite random so it wont be so easy to tell.

EDIT: By the way, 111000μs peak

The download site for DPC Latency Checker (http://www.thesycon.de/deu/latency_check.shtml) has a good article on how to use this utility, complete with screenshots. It states:

" In many cases DPC latency problems are caused by specific types of devices. So you should try the device types listed below first. Network adapters for Ethernet and Wireless LAN (W-LAN) Internal modems Internal sound devices (on-board sound systems) Any PCI or PCI Express add-on card, any PCCard or ExpressCard, e.g. TV tuner cards, ISDN or DSL adapters, modems, etc.

Warning: Don't disable devices that are essential for your computer to function! You should not disable:

any device listed in Device Manager under System devices or Computer, the hard disk that contains the system partition, the IDE/ATAPI or SATA controller this hard disk is connected to, the system keyboard, the mouse, track point or touch pad device, the USB controller external keyboard and/or mouse devices are connected to, the display controller listed under Display adapters.

When you have identified the device driver which is responsible for the drop-outs consult the device vendor's Web site or customer support to find an update for this driver. If this is not possible you may decide to keep the concerned device disabled while you are using streaming applications."

If you have an Atheros WiFi card, the Atheros WLAN driver is a good place to start. Versions earlier than 9.2.1.432 have bad dpc latency. I recommend updating to version 9.2.1.470 or later.

Don't forget to configure your browser to use software acceleration instead of GPU acceleration. It may help with missed keystrokes or keyboard lag when typing in a browser window, such as this forum.

Ok from what I've seen I really must regret buying this. Apparently the lan connection is causing conflicts and also some other random drivers. Asus really doesn't seem to give a crap about the 15" versions which is pretty disappointing. Ill send this over to the guys who sold me and ask them to find a solution, whatever it takes. When I first bought this and saw it had multiple annoying little problems the first thing I did was try to change it for a new one, which sounded reasonable considering how many problems it had, but unfortunately it didnt pass "Asus criteria" to swap out for a new one, oh well.

Once you've determined the driver responsible for the lag spikes, see if you can locate a more updated version that'll hopefully resolve the issue. If you tell us the name of the device and the problem driver version, we may be able to help.

Yeah, disabling the touchpad did the trick for me, now the DPC latency program still mentions that there is lag, but the main problem that is the keyboard is now fixed, at the cost of a disabled touchpad... Does anyone know a touchpad driver version that is confirmed for working properly?
