PHDISK
Running PHDISK
Most notebook computers feature built-in power-saving
functions. This computer has two power management modes,
Standby and Hibernation.
While Standby puts your computer into a light sleep state,
Hibernation shuts off all power after saving the current state of
your computer. The next time you slide the power switch, the
computer resumes from where you left off.
PHDISK creates the hibernation file for the computer to enter
Hibernation mode.
Note: See "Power Management" on page 41 to understand how your
computer saves and manages power.
PHDISK is a utility that works with your computer's BIOS and
Windows ACPI (Advanced Configuration and Power Interface) to
manage the hibernation operation. This includes:
creating the hibernation file which contains the current state
of the computer
checking if the hibernation file is valid
saving and loading the contents of the hibernation file
when entering to and resuming from Hibernation mode
The Hibernation file resides in a contiguous area on your hard
disk, and its size is dependent on your computer's memory size.
When you receive your computer, the hibernation file already
exists on your computer, and you do not need to run PHDISK.
However, if you change the memory size of your computer, you
need to run PHDISK to re-allocate space for the hibernation file.
Follow these steps:
1.
Save your work and restart your computer.
