Small Battery for the Real Time Clock
There is a small built-in battery pack that supplies power to the system in order to
maintain certain system information while the power is off.
If the Notebook is left without a power source for long period of time, this battery
will be exhausted and system information will be lost.
Danger of explosion if battery is incorrectly replaced. Replace only with the same
or equivalent type recommended by the manufacturer. Dispose of used batteries
according to the manufacturer's instructions. Never remove the battery pack while
the power is on as this may result in data loss when the system loses power.
Resetting the System
After installing a software application package, you may be prompted to reset the
system to load the changed operating environment. To reset the system, or “reboot,”
press the [Ctrl] + [Alt] + [Delete] keys simultaneously. This is known as “warm
boot.” This key combination acts as “software” reset switch when you encounter
hardware or software problems, which lock up the Notebook.
If this key combination does not shut down the Notebook, you can reset the Notebook
by using the Notebook’s power button. Should the Notebook lock up for some reason,
pressing this button powers the Notebook off.
Adjusting the Brightness
To adjust the brightness on the LCD screen, press and hold down the [Fn] key in the
lower left hand corner of the keyboard and press the [F7] key to reduce the brightness
or [F8] to increase the brightness.
