Replace power supply: dell 4300S

\015 Are there any schematics or "how-to" pictorials showing how to replace a power supply for my 4300S?\015

Answers :

Replacing a power supply is pretty generic for most PC's. Basically, one just unplugs the computer, removes the side cover, takes note where all the connections go and unscrews it from the back. Installation is the reverse of removal. Be _careful_ to touch the case of the computer before touching any parts inside the computer to discharge any static electricity as it is easy to zap electronic parts unknowingly with static electricity, or wear a grounding strap. If you don't know how to access the inside of the computer, go to the manufacturer's website and download the manual for your model. Dell usually has good documentation.
Probably the hardest part of replacing a power supply is making sure that you have a replacement with the correct connectors. Take the old one to the store with you.

This doesn't specifically address how to remove the power supply, but it does give drawings and instructions for opening the case and removing the various components.
