No battery detected with Windows 7
I've installed Windows 7 RC on my old Acer TravelMate 4001 notebook. Installation went fine, all drivers are working, but only one is missing - ACPI driver. In other words, Windows doesn't know, that there's a battery in the computer and that's quite a problem for a notebook. It's problem with drivers, not with the battery. If drivers are fine and battery us dead, there would be an icon in toolbar saying 'battery is dead'. But i got no icon, no advanced power options, no 'time reamining' indicator, nothing.
In windows XP everything was OK, but since I started using Window Vista and Windows 7 - no battery found and one unknown ACPI device in device manager.
I've searched for help many times on internet without any success, I'm asking here, maybe somebody experienced the same problem and found some solution. Thanks any advice :)
