Good day.
I would like to request a bios for the following laptop?
Model: Acer P214-52-58CH
Model No: N19Q7
S/N: NXVLHE0H11204BA27600
SNID: 11201936276
Symptoms: Laptop powers on but no picture on screen.
I have already checked voltages and all is present. I have checked resistance on the coils to see if the chipset or cpu might be shorted. All resistances look normal. I have tried diffrent ram and I have reset the bios. I have also visually inspected the board to see if anything is burnt or if there are any traces of liquid...09-25-2024, 05:59 AM -

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 Badcaps Team,
I am working on an Acer AL14-31P-C8KV laptop (S/N: NXKS8EA0013490A9C74500) with board number T140AN Rev 3.0A.
I received this unit for repair, but I am uncertain if the current BIOS is correct. There are clear signs of previous work – I noticed flux residue around the BIOS chip, which suggests the BIOS may have been tampered with or reprogrammed before. Because of this, I am not confident that the backup BIN I have is the original dump or if it belongs to this exact machine.
Could you please assist me with:- A clean BIOS BIN for this
