Step 1:
Which operating system ?
Restore Hp laptop factory settings without a Restore Disc Turn on the HP laptop. When the blue HP screen appears, press the "F10" key repeatedly until the "Recovery Menu" appears. A progress indicator informs you of the time before the recovery process is to take place. Click "Next" in the Recovery Menu. Decide whether you want to perform a nondestructive or destructive recovery. A "nondestructive recovery" does not format the laptop's hard drive or erase any personal files on your laptop. However, a "destructive recovery" formats your laptop's hard drive and erases any personal files you have on your laptop. Click "Yes" to execute a "Normal, nondestructive recovery." The restore process begins and your laptop restarts. Alternatively, to execute a destructive recovery, click "Advanced." Click "Yes" to start the "Destructive recovery." The restore process begins and your laptop restarts.

Restoring with CDs Back up all crucial user files if you are able to do so. If your computer will not burn CDs, use flash drives of 4GB or higher to store your data. Alternatively, you can use your network to transfer files. You can then back up your data to CDs at your leisure. Detach peripheral devices such as removable media drives, USB drives and your printer before recovering. Also remove any additional hard drives by disconnecting the cable from the back of the computer. Leave your monitor, mouse and keyboard attached to the computer. Shut down your computer. Place the first recovery CD in the CD drive. If your recovery files are written on a partition, you may be able to select system recovery from the splash screen and your computer starts. Select the recovery option you would like to use. To perform a destructive recovery, click the "Advanced" menu option. Select "Destructive Recovery" and click "Next." To perform a non-destructive, or system, recovery, click "Next" from the opening screen. Watch the computer while it is recovering to the factory settings. Watch for any errors, as the computer will wait indefinitely for a response from you, slowing down recovery time. Also, you may need to insert additional recovery CDs as the recovery program requests them. b> Restoring With Recovery Manager Click the Windows "Start" menu, type "Recovery" in the Search field and press "Enter." Click "Advanced Options," choose "System Recovery" and select "Next." If you are prompted to use Microsoft's recovery program, select "No." Choose the option to back up your files, if you haven't done it already. Once that is complete, choose "Next" to begin reformatting the drive and returning the system to factory settings.

The easiest way to clean the laptop up is to reinstall windows and reformat the hard drive. Was there a set of recovery disks/CDs with this laptop? If so you can do a system recovery and get it to factory specs. If no disks are available you may be able to create them yourself. information on this procedure should be on the HP web site where you may be able to purchase a set of disks/CDs.
Good luck, I will check back to see how your doing.

That is the idea of returning to original condition, but you may be able to recover the operating system only. At any rate, I would back up my data before doing anything.

1. If you use the system recovery and go into advanced, it will erase all personal data and all programs installed, putting it back to the way it was when you first purchased the computer.
2. To get to the system recovery on an hp, you press the key that is indicated during bootup, either F10 for older ones or F11 on the newer ones. It will boot into the recovery mode from where you select the advanced option. It will give you a warning that all your personal information will be gone.

Thank you and please take a moment to rate as fixya. Thanks.

If windows still boots ( and the original hard drive is still in the computer) you can click the start button and find the HP Recovery Manager under the All Programs list. It is probably tucked away under one of the HP tabs.

If windows doesn't boot, and you still have the original hard drive you can press F11 when your first turn it on at the HP logo screen. It should start the recovery program. (The F key can be different on different laptops but most recent HP's are F11)

Be careful, doing a System Restore will erase all your Data, so backup anything important!
