Operating on Battery Power 2-7
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 ( -m
1
).
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.
2.4.2 Fixed Disk Standby Mode
The hard disk drive enters the standby mode when there are no disk
read/write operations within the period of time specified by the Fixed Disk
Standby Timer. In the standby state, the power supplied to the hard disk
drive is reduced to a minimum. The hard disk drive returns to normal once
the system accesses it.
2.4.3 Suspend Mode
In suspend mode the system power shuts off. The notebook saves all
system information onto the hard disk before it enters suspend mode. The
notebook restores this information and resumes where you left off upon
leaving suspend mode.
A necessary condition for the notebook to enter suspend mode is that the
reserved space for saving system information on the hard disk must be
larger than the combined system and video memory size. Under such
conditions, the system standby/suspend button acts as the suspend button.
See Appendix D for information on the ASTDK utility.
