Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Thanks @Markus17411... Ordering CH341 with adapter for the chip.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Thanks @Vesko356 again

Now back to question zero: which one is the BIOS chip? I found there is 8-pin Winbond 25Q80DVSIG chip (at U15) near the C-MOS battery and 8-pin MXIC MX25L12873F at U49. Which one we need to work on (dump, patch and flash)?

Thanks

Thanks @Vesko356.

Newbie updates:

1) How to dump the BIOS: need to get the Intel FPT (Flash Programming Tool). The Lenovo WinFlash can only update the BIOS, not for dumping. I found the Intel FPT from GitHub. Then run from the laptop CMD: FPTW64.exe -BIOS -D T480.bin

2) How to verify the BIOS dump: run from the laptop CMD: FPTW64.exe -BIOS -VERIFY T480.bin

3) How to patch: run the CMD: autopatch.cmd T480.bin
Got the Good Luck message and patched bin file

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Newbie here....

1) How to do the BIOS dump and flash? Which software tool can be used for Lenovo laptop T480 BIOS?

2) A little confused about "Restore original BIOS". It means to restore the BIOS I dumped or need to download the original T480 BIOS from somewhere and restore/flash?

Thanks in advance.
