battery low warning:

THE AUTODIM PROCESS OF THE LCD BRIGHTNESS
The notebook has a unique "automatic dim" power saving feature. When the notebook is using
AC power and you disconnect the AC adapter from the notebook, the system "decides" whether or
not to automatically dim the LCD backlight to save power.
If the LCD backlight is too bright, the system automatically adjusts it to a manageable level;
otherwise, the level stays the same.
brightness and contrast level using hotkeys (Fn-F2).
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.
There are two reasons for the notebook to have the LCD AutoDim feature. The first is to save the
power during the notebook is operating under the DC mode. The second is to save the "favorite"
brightness parameter set by the user.
