Have you tried the file from post #20? If it doesn't work upload your BIOS backup here and someone will help you.
Remember to write your device model number and motherboard number.

What is the device problem?

details on laptop: Lenovo Thinkbook 14 IIL, Model name: 20SL, Factory ID: CS20, S/N: LR0D0C6C, MO: LRN0B032700B, MTM: 20SL001NAK

Laptop problem: i shut it down a couple of days ago and thats it. pretty normal shut down after normal use. now it doesnt POST. power light comes on, charging LEDs respond to charger and charges battery but no HDD light. HDD and Fan spin but thats it nothing else happens no display either, not even backlight...

Things i already tried: reset bios cmos, did the whole power drain by removing battery, tried different RAM, different HDD, nothing worked. The CPU feels warm like its on but other than that nothing else happens.

You can use the file from Post #20 and it will works fine. But you have to take a backup from your BIOS chip before re-flash it, to keep the DMI save.

Hello again.
The bios did not work. I tried 2 files and none work. I assume my original bios might have been okay because I think this is a hardware issue now. After measuring voltages I found abnormal voltage on the DCIN rail. 9.1v instead of 20v. Unless I am missing something there.

Anyway, thanks for the help, but I think I should move my issue to a different thread on hardware troubleshooting.

You're welcome,

Yes, it could be a Hardware issue and you can continue in the hardware section.

Hello! I'm new to BIOS modding and want to unlock thinkbook15 bios (and disable writeprotect so that I can flash internally).

Here's some detailed information:
BIOS Version: Phoenix DJCN31WW
Backed Firmware: Attached to this post

I have tried several methods(ru.efi,setup_var.efi,modding using ifrextractor and uefitool by longsoft [ I know something has been "suppressed", but have no idea how to "unsuppress" them. ] ), but due to my poor knowledge, none of them worked.
I would appreciate it if anyone can offer some advice or help mod the firmware.
