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.... -
Recently I used the official Lenovo bios updater software on my ThinkBook 13s G3 ACN (20YA0005GE). The updating process failed and I got a black screen after powering the device. Of course I did not make an own backup before using the Lenovo bios updater.
I bought a CH341A programmer and was able to make a connection to the chip while it is still soldered on board. But I did not realise that the chip was a 16MB size and selected the wrong size (8Mbit / 1 MByte) before reading the content of my chip. So the dump I did before erasing the chip is only 1MByte big. I fear that I lost... -
Hello everyone,
I’m working on a Lenovo ThinkBook 13s Gen 3 ACN (AMD Ryzen 5 5600U) with a Winbond W74M12JW 16MB BIOS chip
Symptoms:- No display, fan spins, white LED blinking
- Temporary boot after flashing another BIOS
- Dies again after reboot
- Current BIOS dump appears corrupted (mostly FF-filled, no valid UEFI structure)
What I already tried:- External flash with CH341A + proper 1.8V supply
- Flashed GMCN33WW-031F.bin (booted once, then failed again)
- Reflashed original dump → same issue
- Power reset, battery disconnect
- RAM reflow attempt (no change)

What was done so far - connected external monitor via HDMI / USB-C, system reset, BIOS reset - all to no avail.
Also loaded random BIOS for this model from internet - PC booting up but have odd issues when I try to reinstall Win11 on it.

Product Name: Razer Blade 15 (2022)
Product ID: RZ09-0421
Motherboard: CH580
BIOS Versions I work with: 2.02 & 2.06
Bios File Size: 32,768 KB
Dear Forum Readers!
I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).
