Its improtant that you make a good backup of the original bios.Try to make a backup using NeoProgrammer,ASProgrammer or Colibri software ,theyre all available on the forum,search for them.

@trili
What's the programmer model you are using? Some programmers software corrupt the readings/writings from/to the chip, for this reason I recommend reading and saving the chip contents 3 times, then verify all the 3 files are exact copies.

I’m using CH341A. I backed up the chip 3 times and compared them to make sure it was consistent. I noticed there were two chips that looked like BIOS, U15 and U49. I patched the U49. Do you know if it’s the correct one?

I should mention that it makes a musical beep sound.

@trili
Reference U49 is usually for the bios chip in ThinkPads, so U49 must be the correct chip, 16MB (or 128Mbits).
Have you tried to use original bios file and see if the laptop powers on?

Default Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hello

I have a Lenovo T480, 20L6 model.
while getting my hands dirty with ch341a I think I messed something up.

Problem: to begin with my bios was locked with password.

Things I am not sure of
1) I am not sure if my board's bios chip is MXIC MX 25L12873F. (I think it is) (it's next to RAM module)
2) I took backup of above chip, applied the patched bios and laptop started beeping nuts with no display
3) i flashed original bios back, no display and no beeps.
4) finally i'm at a stage where i have lost the original bios dump.
5) I tried T480 patched Bios on Page 14 of this thread and laptop powers on, no beeps this time, display comes on after couple of minutes with Lenovo Splash screen saying "To interrupt normal setup, press Enter" when I do. it does nothing.

currently it's stuck at Lenovo Splash Screen

any help is much appreciated.

Update: I found original factory Bios for T480, when i flashed that I was able to get to password prompt again.

I patched that bios and I have a stuck Lenovo splash screen again, not doing anything on keyboard clicks.

thanks
