Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.
I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...10-11-2024, 03:12 PM -

So far I've been a silent reader, but now I need your help
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!
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 -

Hi, my laptop suddenly shut down while it was running. When I try to turn it back on, the screen stays black and it emits a melodic beep.
I used Lenovo's SmartBeep decoder and it returned error 0284:"TCG-compliant functionality-related error (possibly BIOS code validation failure)"
I then tried to enter crisis BIOS recovery mode by pressing Fn + R at boot. The melodic error code changes, but nothing else happens regardless of whether a USB is inserted. I receive another...06-16-2025, 12:06 PM
