Seagate Hard Drive 40 GB ST9402113A

Hard Drive: Seagate has a downloadable diagnostic program which can help determine the defect. My experience is that once these things fail, it is best to replace. There used to be repair centers where you could send hard drives, but with the low cost of new replacements, it isn't economically feasible. Data recovery is expensive, should you desire that. Google for repair/recovery centers if you want to check out those routes.

Keyboard: It looks like the built-in keyboard is defective. Repair of the original is doubtful. Unless the laptop is old, you might be able to obtain a replacement from the manufacturer. I have replaced a few laptop keyboards in Gateway machines here at the college where I'm employed.
