HI, i have this acer JM50 rev 2.1 board to repair for a customer, the board starts on its own after a couple of seconds of plugging, the power button doesn't do anything, the fan spins at almost full speed, after some investigation I found that the board takes it's time to fully calibrate the voltage going into the chips and the entire system then auto starts, I flashed both chips with 3 known working bios, I get no beep nor anything, the PCH seemed to be overheating a bit, I found a missing transistor near the EC chip which I replaced, I require the boardview file cause I found a pin on the ec chip which was ripped off and I don't know where does it go, I appreciate any possible help and thanks forward!

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...Today, 02:31 PM -

Hi,
My daughter has accidentally managed to kill her Acer gaming desktop it has a blank screen after updating and when you press the power button the fans spin, light comes on and it makes 1 long and 1 short beep and no attempt to boot.
All basic troubleshooting has been done we replaced CPU, GPU and RAM from a working machine and no joy, I also noticed a post on here with the same issue and it was the BIOS. I am pretty sure also because it was doing a BIOS update that stopped it working, she knocked the keyboard out by accident during the update and the screen just went... -

I have already checked voltages and all is present. I have checked resistance on the coils to see if the chipset or cpu might be shorted. All resistances look normal. I have tried diffrent ram and I have reset the bios. I have also visually inspected the board to see if anything is burnt or if there are any traces of liquid...09-25-2024, 05:59 AM
