Hello, good afternoon. I'm looking for the BIOS chip for this laptop because it won't turn on, but I haven't been able to find it anywhere. I would be extremely grateful if someone had it and could provide it to me. I would really appreciate it. I've been told what they ask for in exchange for the BIOS chip.

I've attached a photo of the motherboard, as well as the motherboard and BIOS chip models. Thank you very much in advance. I've also attached a picture of the computer.

Board: WS05 MB-VERA
Chip: Winbond 25Q128JWSQ (16MB)
CPU: AMD Ryzen 7 4800U
Laptop: Acer Aspire A315 (42/43/44/45 series)

I need the full 16MB BIOS region (with AMD PSP), or a verified dump from the same board.
Any matching version for WS05-MB-VERA with Ryzen 7 will help.

Thank you in advance!
 
About this board

This thread is for the Acer 3 A315.

Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.

What this thread covers
  • BIOS (full SPI chip dump, .bin)

Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.

Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.

There is no support on this information. Send correct board code and laptop back cover photo also ypload old bios so we can build new factory bios
 
Good afternoon, yes of course, I've attached the computer's BIOS; it's the backup I extracted.
This sounds good!
Now take a look at motherboard and find board code written like DA0XXXXXXX like this
And upload picture or board code
 
The only codes written on the board are these; I'll send them now.

Here is the serial number: WS0500 P02302150010270

Thank you very much, it's strange that it was empty, maybe it was damaged by a voltage drop. Is it possible that the BIOS was erased?
