The following sections help you fix the issue.

8. Hard reset

A hard reset (or forced reset) erases all information in the computer's memory and may restore functionality.
Resetting the computer forces the system to clear and reestablish the connections between the BIOS and the
hardware.
For more information, see http://support.hp.com/us-en/document/c01684768.
Performing a hard reset might fix the following common conditions:
Windows stops responding.
●
Computer stops before Windows loads, indicated by incomplete startup, blinking cursor on a black
●
background, and errors relating to operating system not found or a missing drive.
Display suddenly goes blank and stays blank.
●
Software freezes.
●
Keyboard stops responding.
●
The computer does not exit Sleep or Suspend state.
●
● An external device stops responding. Turn off the power to that device in addition to performing the steps
in this document.
Before performing a hard reset, you must disconnect or remove all peripheral devices. Start and test the
computer by itself, and if the problem is not resolved, reconnect one peripheral device at a time. To resolve the
startup or operational problem, run HP Support Assistant, or manually install all updated drivers from Microsoft
and HP.
Before beginning, turn the computer over and look for a battery compartment door (service door). On some
platforms, the battery is considered removable but not accessible.
1. Turn off the computer.
2. Remove the computer from any port replicator or docking station.
3. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and
printers.
4. Unplug the AC adapter from the computer.
5. Disconnect the battery.
6. Press and hold the power button for at least 15 seconds to drain residual power.
7. Reconnect the battery and plug the AC adapter back into the computer, but do not connect any of the
peripheral devices.
8. Press the power button to turn on the computer.
