Hi peste, thanks for your quick response. I have tried the link you sent but now the laptop is not turning on at all. Then I have seen that that ist for 14alc05 81yq and I have 15are05 81X2. Then I downloaded from this Poss #3 BIOS it works but my SN and MTM are showing INVALID in BIOS. How can I have my original SN and MTM number in BIOS. Please help. Thank you.

now you have everything you need at post #3...transfer DMI AND KEYWIN yourself...
the bios from post # is virgin, use the HxD program (it's free on the internet), enter both bios into the program (your laptop and the virgin one),
select that interval mentioned in both bios, copy the interval in your bios and pass it to the virgin bios (copy - paste)....and that's it...

I ordered new BIOS chips. I'll try and report back once I receive it.

Thanks.

Thanks, qayyum786. I made a rookie mistake in my haste to flash the BIOS. I forgot the battery was still when I was placing heat tapes on resistors and capacitors around the BIOS chip to prepare for desoldering the BIOS chip. I ended up shorting the BIOS chip (it burned). I replaced it with the same part number from a donor board and flashed your bin file but now there's no power. The laptop doesn't turn on anymore. I tried with battery only, power adapter only, and battery with power adapter with the same results, no power. I guess I might have damaged other components besides the BIOS chip

This is the end of this repair for me.

Thanks, everyone for all the help.

Cheers!

Thanks, Hoaca388 and Shiyab for the files.

I tried Hoaca388's file and it worked. I have display.
However, I lost DMI info (S/N, Model #, UUID and Windows Key) as shown in the picture.
I tried using the Lenovo Uone tool to write the DMI info but I get an error "Locate protocol with LenovoEeprom, status [e]"
"Eeprom fail when reading or writing data."

Is there a way to fix the DMI tool error? I'd like to try that first if possible since I'd prefer not to desolder the BIOS chip again.

shiyab does your file retain the DMI information so I should go ahead and try that if I'm unable to write the DMI info with the tool?

Thanks, again for the help.

Cheers!
