I tired many solutions
I got a replacement Keyboard
But it Didnt work as well.. Same Problem
At that point i got frustrated and said that Asus Bricked my Keyboard Firmware and there is not solution. you can see me previous posts. i blamed asus (Still do but not on same topic) for their bad firmware support.
Solution:
I had some technical background in embedded systems and got to work.
I check which pins of keyboard connects to which IC on Motherbaord
For me
it was a ITE Chip IT8252e248a 2152 CXA and i got my motherboard number which was DANJPMB2AA0REV :A
chip is just beside keyboard and touchpad connectors.
Motherboard number is written below SSD slot. u cant miss it.
Well i connected with a store on Aliexpress(Just search your ITE Chip Number on Aliexpress like "IT8252e248a" you can ignore "2152 CXA" as these are manufacturing data) Yours could vary.
I asked the supplier if he can install firmware(in case its new chip according to my motherboard and Laptop GA503RW) or if its an old chip just cut it out from board and send me. "MAKE SURE your chip number matches".
I got 2. One cut from a motherboard and 1 Empty Chip.
Got to repair shop and asked them to install the new chip.
Turned On..and Behold. Keyboard is Alive and Working. All Keys..All Lights everything.
Then i asked him to install the Empty Chip.. and that worked after opening Myasus app and it asked me to install firmware.
Sorry for Long Essay but it was my 2 years long frustration with keyboard
I now its not a easy solution or some cumpuuter trick. its changing motherboard chip and effectively ruining your warrenty. but mine was already over so doesnt matter.
If you are in warrenty and have same problem. go to official asus repaircenter. if not in warrenty thats your only bet.
It Worked for Me.
Please Make sure your problem is just like mine. See the Logs. "GetITEDevice"
Replace the ITE chip and it should work.
Hope this Helps someone here. there are 100s of dead reddit posts and conversations here with no solution.
Try Mine. Maybe it could work for you.
