I have a PackardBell EasyNote B3605 which has 1gb ram anda AMD sempron 3000+. but as you know the sempron is a bit rubbish.Ihave been given an AMD athlon64 mobile 4000+. The specs i can find say that the motherboard is athlon64 mobile compatible. i swapped the CPU's out and now when i try loading the laptop it starts posting then restarts. I cant get into bios or anything, but i can see that the post is showing the new processor.
This new CPU works because i have the old laptop which boots. my laptop still works because i am now back on the sempron. I can not get to the CMOS battery because its well buried on the topside at the front of the motherboard.
has anyone got any suggestions?
