Re: Lenovo Thinkpad T450S need bios
Hi everyone,
I'm not sure whether this fits here, but I found a Thinkpad 450s (i7, no touch) on the trash. There is a supervisor password set. Does anyone have a BIOS for this version?
Best,

hi, Lenovo Thinkpad T450s, after turning on the computer with the button, the system goes up for one second and goes out, the current drawn is about 0.3A. The bios from this topic helped: https://www.badcaps.net/forum/troubl...450s-need-bios
I have a question: using HeX editor what should I copy from the original BIOS to transfer the serial number and Windows key to the working BIOS ?

I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele... -
Hi everyone.
I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto... -
Hi!
Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).
Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...04-14-2025, 01:56 PM
