LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[Stefan Steff]

Can you send a link to a decent one? I don't have a JTAG programmer. I have heard of it though, but I usually avoid it and use UART with my raspberry pis, since I've only ever used it for serial debugging/console.

I think RT809H is the best price/value in this category...in fact every programmer has good and bad things but to use it once or twice a year then RT809H is a good choice.
In US you find a lot of RT809H programmers on Amazon or eBay. (ex. https://a.co/d/eUE6vcB)
Look for RT809H not for RT809F !

Try with this attached content.

STEP 1: Flash and replace current BIOS with the P50_Bios_2_PATCHED.bin file
STEP 2: Boot the machine
STEP 3: Press ENTER/F1/etc. to enter BIOS settings
STEP 4: Enter any character when asked for Supervisor Password
STEP 5: Press enter when it shows Hardware ID
STEP 6: Press space bar 2x when asked
STEP 7: Turn off machine
STEP 8: Restore original P50_Bios_1.bin BIOS content
STEP 9: Reset BIOS settings to factory default

Good luck!

This file didn't help. My P50 is still dead.😂

Thanks for sharing.
I tried the file you shared,
I wrote it and verified it was written correctly.

It has the same problem as above: it beeps 5 times twice, the fans spin for a few seconds, and then shuts down. No signal.

rewriting my original, it goes back to how it was before with the password.

Test this second version if you still need , let me know.

I ordered the one you sent, however I've noticed something. Underneath the black "tape" around the motherboard, I found a messed up chip. There is one wider chip near the Ethernet port that is cracked and has exposed copper coils! I looked into it some, if this is shorting out I think it may be causing my issue. I'd like to have the programmer anyway, but this might be the real issue with my laptop. I hadn't considered hardware damage because it was powering on fine before, but I believe I may have jolted it slightly which caused a short in the chip. I think removing it entirely should stop the short, it would just prevent the RJ45 from functioning. Thank you for your help! I'll come back here if it's not that chip and still doesn't boot.

OK.
Rewriting the EC chip must be the last try if any else isn't working .
A very good hardware check before it's also a good idea...
Good Luck!

Any idea if this will work on a P14s G5?
