Thank you for all answer. @Schubert This tipp is verry good. I have do that and think it's work now. I have a 3624NWXMi but with Bios version 1.06 and not with 1.04. I think that is not a problem. You have also a Aspire 3620 series notebook? I have a questen: My Mousepad, Wlan Card and Bluetooth doesn't work. You have a idee why not work that? greet, Pascal
