Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

@trunguntilyou
This is the list I use, seems like it contains most of the models compatible with the DXE driver patch solution, if it's not in the list, most likely the DXE driver patch won't work, specially if BIOS is 32MB:

[CODE]ThinkPad 13 (20GJ, 20GK, 20J1, 20J2)
ThinkPad 25 (20K7)
ThinkPad A485 (20MU, 20MV)
ThinkPad Helix Gen 3

ThinkPad E14 (20RA, 20RB)
ThinkPad E470 (20H1, 20H2)
ThinkPad E480 (20KN, 20KQ)
ThinkPad E485 (20KU)
ThinkPad E490...

Re: ThinkPad L450 _ NM-A351 BIOS Password Unlock

AUTOPATCHER is not working on this Lenovo laptop!

here is a solution to unlock L450 BIOS.
For safety reasons make dump backup and take care during security chip shortening. Make also picture on bios SERIAL number and so on (just push enter when as for password to go inside locked BIOS).

1. Prepare something to short circuit SDA and SCL line of security chip.
2. Remove hard drive.
3. Switch on laptop and immediatelly shortcircut this 2 lines, as on picture.
4. When laptop will show...

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

I just picked up a thinkpad l450 core i5 vPro from a flea market. Its BIOS is locked. On investigation it has two BIOS chips:


One chip is labelled Winbond 25Q64FV51Q and the other Winbond 25Q32FV1Q.

My question is how would I remove the BIOS lock on this? I have used the tool before to remove the password on a single chip model.

Re: lenovo l450,nm-A351 rev 1.0 schematic need

No Sir,
This is some thing different. If you search for PQ33, PQ34 it shows no match found. But physically it is available on mother board.

Hope some other schematic also available. I am also looking for lenovo thinkpad L450 schematic and boardview.

Thanks & Regards,

Zarrar
