Wondering if someone can help me restore the “INVALID” entries in my BIOS?
Backstory… The laptop wouldn’t post, fan would spin, but nothing would display on the screen. I used a CH341A programmer to write a stock image I found on another forum to the BIOS chip, but now several fields on the setup screen say “INVALID”. Everything seems to be working fine and I was able to update to the latest BIOS version, but I’d like to see if it’s possible to recover the info from the dump of corrupt BIOS or enter it from the info listed on the bottom of the laptop.
my problem is this… my laptop motherboard burn… so i order one from aliexpress.
the laptop is working with the mother boart i order but i have a problem with the keyboard.
when i press number 7 it write 74 if i keep pressing it write 44444
if i press 4 it write 74 and if i keep pressing it write 444444
and so on with other keys g =gt and keep pressing it is ttttttttttttt
if i press h = hy and if i keep pressing it is yyyyyy
i have remove the keybord and i manualy short the pins to see if the problem is my keyboard… the problem is not my keyboard, i do the same think
so i wondering if the problem is the bios…
