The Compaq 6715B is a notebook computer that, like many other modern notebooks, stores all of the information needed to recover the system from a catastrophic failure on a hidden area of the hard drive where it cannot be deleted without extensive tweaking. This ensures that, as long as the hard drive is functional, the computer can always be returned to its original factory state if needed. Use the recovery partition of your Compaq 6715B if you need to restore the system to its original state.
Turn the computer completely off and connect it to a wall outlet. The system recovery will not complete if the computer is on battery power.
Turn the computer on. Tap the "F11" key repeatedly until the graphical interface for the recovery partition loads. Click "Next." The first screen will ask if you would like to use the Windows system restore feature to restore your computer to a previous state. Click "No" to proceed to the full system recovery.
Click "Yes" when asked if you would like to recover your system, then click "Next" to start. This process will format your hard drive and reinstall Windows, returning the computer to its original factory state.
If you are able to load Windows on your Compaq 6715B, you can access the recovery partition by clicking the "Start" button, then navigating to "All Programs," "HP Backup and Recovery" and "HP Backup and Recovery Manager." Make sure that all other recovery options have been exhausted before attempting this, however. If the computer can load Windows, it may be possible to repair it without reinstalling the operating system and losing your files.
If you have access to your computer's hard drive, back up all of your files before using the recovery partition. In the recovery process, the hard drive will be formatted and any data that is not backed up to an external storage device will be lost.
