The hard drive needs to be replaced.  What model system do you have?

If it's under warranty, call Dell with the error and they'll replace the drive.  If it's out of warranty, you will need to purchase a new 2.5" 9.5 mm or slimmer SATA notebook hard drive.

Im not sure how to check with the type of model if its the product key or express service tags?

Go into the BIOS setup (F2 at powerup).  The system model will be displayed on the first screen.

um, im not sure if anyone is reading this post properly

MY NOTEBOOK WILL NOT TURN ON!!!!.

it gave me the issues prior of the error message but now it just WILL NOT TURN ON.

I did all that and my computer will come on for about 5 seconds then the screen goes black but the

button stays lite. My question is ___I have had a battery replacement message for awhile now but it

has always worked with the AC plug. Now it will not, can this be the reason? Could this have harmed

my computer or should I just buy a new battery module to fix the problem.

Remove the battery, unplug the system and hold the power button for 30 seconds.  Plug the adapter into the wall and ensure the LED on it (or on the power cord) comes on.  If it doesn't, the adapter is faulty.  If it does, but the system won't power up at all, the mainboard is bad.  If the system is out of warranty, you might want to consider a warranty extension - the cost to replace a mainboard will be a few hundred dollars.
