Re: Need toshiba L755 bios file
i know it sounds stupid but bare with me
on the power button socket you got 3v or after the socket----> foil -------> power button you got 3v?
my friend i got a P755 for nothing because it was the power button problem

Just cook it! It's already broken. -
Re: Need toshiba L755 bios file

Re: Need toshiba L755 bios file
The way you describe your problem it doesn't sound like a bios problem.

Re: Need toshiba L755 bios file
yup not a bios problem. I just reprogrammed it using known working ones from a tech friend, but still same results. I'll do what you suggested and maybe I found faulty components again. have a nice day. thanksComment

Hi all,
My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
The charging red LED lights up, but the charging screen doesn't show any indication.
When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
(I've tried removing the battery and resetting the device, but the issue persists.)

Hi everyone
I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
Programmer models: XGecu TL866II Plus / T48 / T56 / T76
Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
There's also an extra OTP Secu.R... -

Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)... -
Hello Everyone,
I have Thinkpad T560 Which has corrupted BIOS. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need a bin file for the BIOS. I was able to extract the .exe file of BIOS from Lenovo given here in this link:
https://pcsupport.lenovo.com/au/en/p...me=BIOS%2FUEFI
In the extracted files, I see that BIOS containing file has extension .FL1 and I need to extract or convert it...
