I ask this because I don't want to buy the wrong part of the laptop. Does anyone knows if this is caused because of the laptop missing the battery or something else?

Has a sketchy power plug. Thought loading a slimmer OS might make the experience generally better. Made a dual boot with linux. Worked fine with both operating systems for about six months or so. Then failed to load either operating system . Windows safe mode fails when it hits agp.sys. Linux returns a bios error [        0.060000]  . . MP-BIOS bug:  8254 timer not connected to IO-APIC . XP Recovery console fails to load. Ended up loading FreeDOS which works. Tried to load 95, 98, ME, all fail at around 20%. Maybe a driver corruption or conflict or something has occured in the BIOS? Any help would be great. Thanks!

For instance, Ram cover needs removing to allow access for screen wire removal. Also the top fan is connected to the heat sink frame and has to be removed before not left in place until later in the process.

When all instructions and screw removal is complete the keyboard is firmly fixed on the drawer side but no screws are visible!

I am trying to replace the DC input jack as it has an intermittent connection. The AC DC converter shows a steady 18.6v of output.
