NOTE: HP diagnostic solutions are developed to test components typically included on HP products. They may not diagnose all third-party accessories that can be added to the system.

Turning off the computer

To properly turn off the computer, first shut down the operating system software. In Windows 7, POSReady 7, and Windows XP Professional, click Start > Shut Down. In Windows 8.x and Industry 8.1, point to the upper-right or lower-right corner of the Start screen to display the charms, and then select Settings > Power icon > Shut down.

Depending on the operating system, pressing the power button may cause the computer to enter a low-power or “standby” state instead of automatically turning the power off. This allows you to conserve energy without closing software applications; later, you can start using the computer immediately without having to restart the operating system and without losing any data.

CAUTION: Manually forcing the computer off will cause the loss of any unsaved data.

To force the computer off manually and bypass the “standby state,” press and hold the power button for four seconds.
