It's a bad hard drive. The only solution here is replacing the hard drive.

Remove the battery, and connect the AC power. Then, try to start it.

Disconnect the AC power, and remove the "new" disk-drive.
Then, connect the AC power, and try to start it.

Disconnect the AC power. Remove the "new" RAM, and put the "old" RAM back in.
Then, connect the AC power, and try to start it.

If it does start, add the "new" disk-drive, and try again.

If it does start, add the "new" RAM, and try again.

Hey!

Here's a link for the hard drive removal. Click here to get there.

Hope the manual helps! :D

that error actually refers to a hard drive issue/failure. You may attempt a reformat and reinstall, but if it fails, you can proceed to get a new hard disk. You can get in touch with Dell for warranty replacement if applicable, or order a new hard drive. You may then decide either to get the same capacity or upgrade to a higher capacity drive.

2. remove the hard drive and re - insert it into the hard drive slot.

There is a trick to getting an overheated and damaged hard drive to run for a short period of time, maybe enough to get your data off of it. Place the damaged hard drive in a tupperware bowl with a lid. Get a can of refrigerant from an auto parts store, wear gloves....open the refrigerant with the attached hose and direct the refrigerant into the bowl keeping as much in there as possible. This will freeze the bearings and in a lot of cases allow the device to work for short period of time. This of course will not work if the problem is a damaged read/write head or controller card.

THERE SHOULD BE A FEW SCREWS ON THE UNDERNEATH OF THE LAPTOP, UNDO AND YOU SEE THE HARD-DRIVE, DISCONNECT IT TAKE TO THE SHOP, BUY NEW ONE REPLACE IN REVERSE ORDER.
