Hi volinakis, thanks for the provided bios, now my question would be can I use some kind of USB + key combination method to install the new bios or do I need to use a ch341a programmer ?
Thanks again !!
Thanks again !!

Thanks for the Bios file Volinakis !
Just a question now, can I add it on a Fat32 USB drive and use the FN+ESC+Power button method to flash it ? Or do I need the ch341a programmer and directly erase/flash the chip ?Comment

Hi again volinakis , sorry for the spam but I come with a proper dump now.
Turns out the Motherboard on these a715-42g models have some interference that don't allow you to read the bios chip properly while the chip is still mounted on the board by using ch341a and Clamps.
So I got a ch341a flash socket, removed the bios chip from MB and managed to read it / identify it with NeoProgrammer 2.20 in the first run.
I made 3 dumps and compared all with HxD editor and they are all similar, here is the dump, could you kindly adapt the DMI thing you mentioned?
Many thanks in advance and sorry for spamming........

Hi volinakis , I flashed the bios, soldered it back, now the fans don't even turn on, there's no post, no image, initially the fans turned on for a few seconds.
Could this be caused by the new bios ?
Thanks again !Comment

Hello everyone,
I need help with my Acer Aspire 5920G laptop. Its original GeForce 8600M GT graphics card failed, so I replaced it with an Nvidia GeForce 9600M GT MXM card.
**Problem:** The laptop powers on, but there is no display (black screen) on either the internal LCD or external monitor. This indicates a BIOS compatibility issue with the new graphics card.
**What I have tried so far:**
1. I have my **original stock BIOS dump (1MB .BIN file)** from my laptop, which works and allows the laptop to power on normally (but no display with 9600M...07-02-2025, 02:31 PM -

Hello,
I am experiencing the following issue with my laptop. I have an Acer Aspire A717-71G with a motherboard model C5MMH/C7MMH LA-E911P Rev. 1A. Unfortunately, the original board stopped working, so I purchased a replacement. The new board is the same model but a different revision (Rev. 1B). From what I understand, this should not cause compatibility problems.
However, the replacement board came with a BIOS version intended for the Acer Nitro 5 AN515-51, which causes the keyboard to function incorrectly. I attempted to reflash the BIOS chip using a CH341A programmer... -
My laptop model is EX215-23-R7NG
BIOS chip XM25QU128C
Here is my original bin file, as well as how the BIOS chip looks like
My situation is if I press my laptop power on, fan turns on for the first five seconds and turns off, no display (not even acer), but power indicator is on, and the CPU gets warm, even caught one time if powered on for long (before an hour) the fan turns on again, is it only right that I'm approaching via BIOS?
Before I got into this situation, I was just watching movies, and while turned on, pressed the battery reset button and cleaned...
