3-10 User’s Manual
If the LCD backlight is too bright, the system automatically adjusts it to a
manageable level; otherwise, the level stays the same. If you want a
brighter picture, you can then adjust the brightness and contrast level using
hotkeys (Fn-F21).
If you reconnect AC power to the system, the system automatically adjusts
the LCD backlight to its original level — the brightness and contrast level
before disconnecting the AC adapter. If you adjusted the brightness and
contrast level after disconnecting AC power, the level stays the same after
you reconnect the AC adapter.
Hard Disk Standby Mode
The hard disk enters standby mode when there are no disk read/write
operations within the period of time specified by the Hard Disk Standby
Timer. In the standby state, the power supplied to the hard disk is reduced
to a minimum. The hard disk returns to normal once the system accesses
it.
Hibernation Mode
In hibernation mode (also known as zero-volt suspend-to-disk mode), power
shuts off. The notebook saves all system information onto the hard disk
before it enters hibernation mode. Once you turn on the power, the
notebook restores this information and resumes where you left off upon
leaving hibernation mode.
A necessary condition for the notebook to enter hibernation mode is that the
reserved space (created by the Sleep Manager utility) for saving system
information on the hard disk must be larger than the combined system and
video memory size. Under such conditions, the sleep hot key acts as the
hibernation hot key. See section 5.2 for information on the Sleep Manager.
