Hi everyone,
I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
BIOS access (F2) and Boot Menu (F12) are no longer possible – the system instantly reboots after the rollback messages.
I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain... -
Hi all,
I have a Western Digital Sentinel DS5100 NAS system which has stopped working. It has dual BIOS. I bought the system second hand with an already broken primary BIOS (it rebooted multiple times until second BIOS was used).
It worked until recently. The system was idle in Windows Server 2012 and a BSOD occurred, I think it was 'critical process died'. Thereafter it didn't boot, it just sat there with no video output and fan speed at 100% (there's a proprietary Windows driver by WD which controls the fan, outside of that it always runs at 100%).

Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
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.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice...
