thanks friend, I flashed the bios as you attached it but nothing to do, it doesn't work.
Monitor always black and if I try to remove the RAM the buzzer doesn't beep

Ok, so from my dump you say it corrupted?
When I try to write the flash, I have all time an error on 0x00020040, so I cancel the flash 4-5 and I try again to write IMAGEO2H.rom...success.
Thanks for your help.
PS before to open this thread I search and search for a solution 😅Leave a comment:

Okay, I tried to extract files directly from the installer using 7zip, but I get many large 64Mbit files. When I try to compare them with each other using a hex editor like Neo, they are all different from each other. So, which one should I use? The files are of the following types:[LIST][*]IMAGEO2H.rom[*]O2H3X.rom[*]310/O2H3X[*]310/O2H3X.rom[/LIST]
All are 8192kbytes in size (i.e., 64Mbit), but none are file.bin.

Re: turn on...turn off Acer E1-572
I know they have two different voltages, but I read on the Internet that the PC should start, at the maximum there will be errors, but the PC should start.

Acer E1-572 V5WE2, LA-9532P Rev 1A
Hi dear, my laptop has broken and with the multimiter i check all tension on mainboard and on VGA_CORE i have a short....but if i measure the resistence i hae 27ohm, so i think is a bad capacitor.
Now i search for a schematic.
Thanks to all
