Battery Calibration
The purpose for this process is to provide a long battery life for your system battery pack.
1. Turn on the computer, when the text appears, press [Del] or the [Delete] key until the system enters the BIOS
Setup screen, you may now make the necessary changes.
Press the arrow key until it reaches the “Exit” menu screen. Again press the arrow key and select the
“Battery Calibration” item. Press the [Enter] key and disconnect the AC adapter then press the [Y] key until
you hear continuous battery low-low warning beeping sounds. The system will be fully discharge and
shutdown completely.
Connect the AC adapter and let the battery fully recharge. The “Battery Charge LED” which is located at the
left side of the notebook will light indicating it is in charging status.
When the battery charge LED turns off will indicate the system is fully charged.
Repeat step 1 to 4 once again.
The battery is now fully calibrated.
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.
