hello, unfortunately I don't know the model of this notebook because the license plate is missing, when I insert the power connector the power and wifi LED lights up and it doesn't respond to the commands, I tried to program several bios files but it doesn't work, I measured on the U18 pins (chip bios), and the voltages are very low around 1volt instead of 3.2v removing the chip are normal, in this regard I wanted to ask a question: the bios chip is a gigadevice GD25B64BSIG if I put a W25Q64BSIG winbond are the same?

GD25B64BSIG if I put a W25Q64BSIG winbond are the same?
same and you can use a ic 1.8v
you must have all voltage good before flashing bios
your pc is Toshiba Satellite C55-B PSKTWV
or L50t
or toshiba l50 b DABLIDMB8E0 REV E

Re: toshiba sat dablidmb8e0 rev e : no start
it does not work .... I begin to think that in addition to the bios there is another problem, as I said in another section about this case and that is that on the pins 1-2-7-8 of the bios chip I measure 0 , 7v instead of 3,2v while when it is off I measure 0v, if I turn on again I measure 3,2v but the pc does not turn on, the voltage of 0,7v I discovered that it comes from PQ10 from pin4Comment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
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....
