Turning off the computer

To properly turn off the computer, shut down the operating system software.
CAUTION: HP does not recommend holding down the power button to shut off the system. Doing so can
cause loss of user data and may damage the storage device. If the system becomes unstable and no other
alternative is available, please give the system sufficient time to wake up completely after you reboot the
computer. This may take up to several minutes, especially on larger-capacity or solid-state devices. For more
information, see Risks of unexpected power loss on solid state drives at
GetPDF.aspx/4AA6-1470ENW.pdf. HP computer white papers may also be accessed through HP Performance
