Re: ultrabook aspire p3-171 bios
I used CH341A USB EEPROM BIOS Programmer Programmable logic circuits with SOP8 clip with the neoprammer, plugged into the GD25Q16BSIG chip to extract the bios. Motherboard no. DAEE3MB1AE0 rev:E Product serial number: NXM8NAA005343AAFC47600.
And for the question after three bad passwords the screen is black.Comment

Re: ultrabook aspire p3-171 bios
It's not the bios chip, you got it wrong.
Look for the bios chip somewhere else on the motherboard, it should probably be 8Mb. You can write the chip markings here in the thread so we can tell you if it's the right one.
Edit: The serial number is also wrong.

Edit: As far as I can see, it will turn out to be the dual bios in your case 4Mb+2Mb (2Mb dump at your first post) but we'll see when you upload the dump from the 25q32.

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 everyone,
Iβm 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, Iβm 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. Hereβs a full breakdown:
𧩠Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight

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... -
