Acer gh51z LA-K851P nitro 5 dead KB9022QD

[nivirus2000]

Hello I have a nitro 5
GH51Z LA K851 with no power, does not charge or show any signs of life.

Found a short to ground in line +3VLP line, the short was coming from UE1 KB9022QD. Took it off and short went away.

I ordered a new UE1, not knowing I have to reproam it but i am afraid the original IC is dead. I wonder if anyone has a dump so I can program the new one.

Thanks in advance

I don't know how to read and write an SIO chip with CH341A, but maybe someone else can help you..

It's good to know, You're Welcome.

If the Keyboard works fine in the BIOS Menu but it doesn't work in the OS, this should be a Driver issue, try to install a New OS.
Also to be sure, you can test the Keyboard in the Language step before installing the OS.

Re: Acer gh51z LA-K851P nitro 5 dead KB9022QD

I updated bios and firmware, loaded usb linux/hirens boot cd and other distros just to test and no go, the OS detects the keyboard but won't register key strokes.

Not sure, I'll have to retrace my steps and see if I knocked something off by accident
