Remove the hard drive and read it as an external drive using another computer. Also, test it and fix it using a Norton Utility (it can be downloaded from CNET; go to google and search it using keywords: "Norton utility download cnet")

This is because the Hard Disk Drive has failed and you need it replaced. If your warranty is still valid, take it back for repairs or buy another hard disk drive altogether.

On a jammed switch for the batt on the (old) compaq I would take in for repair so is not you the done that damages anything around the battery casing.
