    Hi, I bought Acer Travelmate 5520 computer knowing that there might be something wrong. I received the machine yesterday and I have noticed that the machine takes unusually long time to boot Windows, any of the supported version, XP, Vista or 7. When the machine boots to desktop it works without problems, other than it cannot shut down properly, it hangs at "shutting down Windows" screen. What makes things even more strange is that Ubuntu Linux has no problems with this machine, boots, works and shuts down at normal speed.

    I tried to update bios, it is now 1.14 but I can't, it complains that my battery does not have 30% charger which is true because it's stone dead.

    Suggestions?

    Hi, Is this a latest BIOS ? I have also TM 5520G and the latest BIOS is 1.17.

    Yes, bios has now been updated but the problem did persist even when I installed XP again. However I have managed to fix slow boot and shut down issues by changing acpiec value using Regedit.

    ACPIEC warning | Windows Problem Solver

    However there is still problem with suspend mode, the machine does not react at all when the lid is closed, even when it is set to do in Windows Power Management. If I put it to suspend mode from Start menu the screen goes black but fans are still on, it seems that it is "stuck" between normal and suspend mode or something.

    Hi, about suspend to RAM and disk. It depends on drivers. When I have x64 OS Vista, 7 and 4GB RAM, AMD has (had) a bug in drivers which cause problems with this issue. Now I have 32-bit OS Win7 and everything works just fine (ATi 10.7 drivers, no modding).

    Update for my case: It seems that the lid thing is mechanical problem, the "spike" (sorry about my english, not my native language, can't find better word right now :) ) on the display does not touch the switch on the computer when the lid is closed, but if I press the switch down the lid event is registered and Ubuntu begins suspend script. However Windows does not do anything else than dim the screen which I believe is not software based.

    Suspend mode still crashes in Windows XP when started from Start-menu, by looking eventmgr.exe there is indeed ACPI error registered which says that suspend mode failed. I guess it is APM which is doing restart and shuw down functions since they works well after the registry mod? Is it possible to force APM Suspend even though ACPI is installed?
