LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[loveUKnuckleGrumble]

Hello, i had the same problem as awena n the exact same device (e585 20kv r5 2500U)

Hello, I have a problem with my Lenovo ThinkPad E585 laptop (AMD Ryzen 5 2500U). I have a problem at this point in the manual:
STEP 4: Enter any character when asked for Supervisor Password
When I press F1, a screen is shown asking me to enter the password (on a black background, like a command line) but the keyboard stops working, no buttons on the keyboard work. I also tried to connect a USB keyboard - unfortunately the same thing happened. I tried to turn off and try to repeat all the steps again and again several times - but unfortunately nothing has changed, the laptop seems to freeze. When I restore the backup bios, everything works fine in Windows 10, the keyboard works, the laptop works without any problems (but the password in the bios unfortunately remains and I can't reinstall Windows). I also tried the already patched dump from the forum (post hoaca388):
https://www.badcaps.net/forum/troubl...s-dump-request
But the result is the same, you can't enter the password on the patched bios. Maybe someone knows a solution, what am I doing wrong?

but by patching the bios attached by "big-boss1" from https://www.badcaps.net/forum/troubl...b531-bios-dump I managed to delete the password.
Attached is the patched version.

Hello everyone,

I really need help! I dumped the bios, all good. Patched it, all good. Flashed the patched one, all good. Did all the steps, all good. But when flashing the original bios again, suddenly the chip isn't recognized by the CH341A anymore, it always says IC not responding. Now when I turn on the laptop, the fan shortly spins and the keyboard backlight comes ip for a second, then nothing happens. What could I do? I do not have the equipment or ability to solder the bios chip.

Kind regards,
olivettinho

Hello,

Unfortunately, there are not many options in this situation.

First of all, if possible, try to reflash the last BIOS dump that was known to be working. If the programmer still cannot detect the chip and reflashing is not possible, then there are two main possibilities:

1. The BIOS chip itself may be damaged. In this case, the only real solution is to replace the chip with a new one that is preprogrammed with a correct BIOS dump.
2. Carefully inspect the motherboard around the BIOS chip area. It is quite possible that during previous work (or clip attachment) a nearby component was damaged or shifted out of place. Check especially for small resistors or capacitors next to the BIOS chip

Had a similar issue on my T480s. Ended up having to desolder the chip and use a programmer to flash it off-board.

Did that now, too; wiht original bios, fan spins 2 short times, powerled on the button stays on, but nothing else happens. I also used a spare bios chip, nothing changes.

Thanks for the info,
Try first this dump.
It should work if you successfully patched and run your original dump making all steps.
If it's not working post your original dump.

_EDIT_
Added a second version and a third with brand new BIOS region and a clear ME region as you mentioned.

Thanks, I tried the V3 as it is the Corporate LP, but still the same issue; fan spins 2 times for about 1 sec, Screen black, LED on the power button constantly on; CAPSLOCK no reaction
See my original dump attached

Please try to let it on for at least 10 minutes...

OK I'll try, after about 3-4 minutes, the fan starts spinning continously and the CPU seems to get warm.

Did that now, runs for about 15 mins, no other reaction; do i need to replug the power cord after the 15 minutes? Or should it show something on the screen?

It should give some picture within 10 minutes...
