    Acer gh51z LA-K851P nitro 5 dead KB9022QD

    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

    you also need a programmer for SIO chips... post the original laptop bios and the full name and model...

        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.

                    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

                          Model: AN515-45-R841
                          SN: 23506151734
                          5600H - GTX 1650 4G

                          when the device came to me the main BIOS and EC BIOS were completely blank. probably the device of the technician before me couldn't read the chip. bios + ec bios waiting for your support thanks.
