  • Acer AO 751h freezing - Troubleshooting
    • Update BIOS to v.3210 or v.3211

      Didn't fix the problem.

    • Disable Hardware Acceleration of the Graphics Card

      I have no problems so far after disabling this feature.

      However, crippling the performance of my netbook in order to stop the freezing does not seem a proper solution to me...

    • Update GMA500 drivers to v.2020

      Didn't fix the problem

    • Try using a Fan Control app, in case the problem is temperature related

      Didn't fix the problem.

    • Try changing RAM module

      Unfortunately I don't have the chance to try another SODIMM RAM module and they are still really expensive to buy just to try... €22 for 1GB, €40 for 2GB.

      Change RAM module to CORSAIR SO-DIMM 2GB DDR2 667MHz (VS2GSD667D2)

      SAMSUNG 1GB 2Rx16 PC2-5300S-555-12-A3 seemed to freeze the netbook.

    • Change IRQ priority

      IRQ8 top priority
      IRQ16 is second and IRQ17 is third.

      Howto : Create DWord value (named ‘IRQ#Priority) in ‘HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl’
      ‘#’ is IRQA number. Ex) IRQ8Priority

    • Have the mobo replaced by ACER

      If you are lucky, you may have your mobo replaced by a newer one, with Z530 processor @ 1,6GHz!!

    • Change Graphics settings

      Try to change the following settings:

      Under Options in Graphics - Enable Performance Mode is ticked
      Under Power Settings - tick the Intel Display power Saving Technology, and drag the pointer to maximum quality

    • Acer Aspire One 751h Bios Recovery

      In case your 751h happened to freeze during a BIOS update, it is very likely that you end up with a bricked netbook.

      User lightt, from AcerAspireOne forum, suggests a solution for recovering from this situation:

      BIOS recovery solution

    • Possible driver issues

      Try using Realtek Audio Driver 6.0.1.5854 and Bios 3212. It seems to work in certain cases.
