The laptop won't turn on. Nothing happens when I push the power button, and leaving it plugged in has no effect.

First, check to make sure the CD isn't scratched. Try several different CDs or DVDs. If none of them will load, follow the replacement guide for the CD Drive here. You can also check out the the Troubleshooting Guide for more information.

Try restarting the laptop. If the problem persists, the keyboard is probably broken. Visit the troubleshooting guide here for more information.
