Ctrl Key Not Working

[luvpizzas]

Hi everyone.
I have Asus g15 503qs. The problem is left ctrl stopped working (both on windows and linux) and it works rarely for hours when i press ctrl for more than hundred time (i don't think it's a hardware issue). i tried nearly everything except for erasing system. does anyone have a clue or is there any specialist who can help? 
it's been almost a year. maybe it's because of bios update or keyboard driver. i tried everything. sometimes it works then suddenly stops working. Ctrl key is not broken or not damaged. i'm waiting for a technician's answer. I can give you more details if you have questions. Thanks again !

(UPDATE) Looks like LEFT CTRL worked when i take my nvme out and boot system using live os, but the next time it didn't. (weird) 

I'm trying to run the rog keyboard firmware update tool (rog kbfw). but the thing is that I already have the latest keyboard firmware installed, but I'm sure the keyboard firmware driver is broken. I can't reinstall it. Now I know why it affects both Linux and Windows. due to an error installing the keyboard firmware. it sees that the driver exists. but doesn't know it's broken or faulty. it launches and waits a second and the message "You have the latest version of firmware" pops up. All im thinking about is force-overwriting the existing faulty keyboard firmware driver.

Hi @luvpizzas ,

Have you tried removing all external devices and power, then holding down the power button for 40 seconds to perform an EC reset while the system is powered off, and then reconnecting the power and booting up to test?

Please remove ASUS System Control Interface v3 from the device manager, reinstall ASUS System Control Interface v3 version V3.1.22.0, and follow the instructions in this link to uninstall the keyboard driver, then restart the computer. Upon reboot, the system will automatically reinstall the driver, then check if the Ctrl key functions properly. Thank you.

i dowgraded my bios to factory version from official drivers, removed ASUS System Control Interface v3 v3.1.24 and installed v3.1.22 then shutdown my laptop. then i disconnected everything, external devices and power, removed battery, ram, ssd, everything. and i waited for 30 minutes. then I held down the power button 40 seconds, next time, 60 seconds, 2 minutes. i thought the power light would flash but didn't happen. anyway, i pressed the power button and system started to boot (actually it should only boot when ac is plugged after ec reset). then i started thinking that EC Reset didn't happen, or did i miss anything here in process?  thanks for helping me further!!!

you can see the same issue everywhere, they're saying that rog keyboard firmware update tool (fix) bricked their laptop keyboards. some said whole keyboard bricked, some said fews keys stopped working. we as users don't really have to dig the firmware drivers and debug it. asus makes good hardware but always sucks at software development. I hope "real specialist working at Asus" could fix the issue for Asus users.

Hi @luvpizzas ,

Thank you for your response. Regarding the EC reset, it only requires removing the power and external devices (memory cards, USB, monitor, etc.), then pressing the power button once for 40 seconds and releasing it to complete the process.

The links you provided are for discussions on centralized issues for different models, which may not entirely match your model and situation (one of the contents has been deleted).

As you mentioned, please try reinstalling the system to test if the issue is caused by keyboard firmware damage. If the problem persists after reinstalling the system, we recommend you visit a local service center for further hardware checks. The information above is provided for your reference.

Thanks for your response. I did everything you said regarding the ec reset. i don't know if it worked or not. the links i provided might not have the exact same problem, but it's a similar issue if you read comments. i could send hundreds of threads about it, but it's a time waste. theres's no local service of Asus here in my country. i just want to talk to a technician. you always reply with the same answer maybe you have to recruit a robot for that. please help me out

Hi @luvpizzas ,

We understand your frustration with the random key pressing issue. Since this problem could stem from either software or hardware anomalies, many users have found resolution through performing an EC reset or reinstalling drivers. Based on the tests you've conducted and the description provided, there may be a hardware anomaly present (especially considering the issue occurs on both Windows and Linux). To confirm whether it's a firmware anomaly, we recommend testing by reinstalling the system. This can help determine if the issue is caused by hardware abnormalities. Thank you for your understanding.

i don't know when it's going to be fixed. you must send me fixed updater tool or custom flasher which some people got from asus's email.

Hi @luvpizzas ,

Thank you for your reply.
Since the discussions you provided seem to involve different models and are quite old, they may not exactly match your situation. Based on your tests and description, it seems to align with our speculation of a hardware issue. We recommend that you send the laptop to your local service center for further hardware diagnostics. We apologize for any inconvenience this may cause.
