Re: BIOS for Acer Aspire E1-771G - Mainboard VA70/VG70 ver. 2.1
Hello there buddy ,, better to post your backup of both chips as I think on this board the whole BIOS is on two chips ... so you need to combined 4MB and 2MB there is no such a thing for KBC to have 2MB. There is a way to fix the bios and clearME region for it. -

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,
I’m 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, I’m 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. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

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... -
Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder...
