        If you havent been able to get the problem fixed try removing the Battery and hard drive. somewhere near the gpu you will find g2201 <> and two small pins to the right of them. short the two for a few seconds. then start your computer. go to bios and if the password is not gone repeat the process.

          I'm not sure if this will work for you but some laptops you can short the bios battery,With a pair of tweezers, like on the acer 5720 that will clear the eeprom chip then you go into recovery mode and upload the new bios ..

          Or desolder the chip reflash it.

              Acer Aspire 5920G - Requesting Modded BIOS (9600M GT) from .WPH for CH341A Flasher

              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...
