Whenever possible, keep the AC adapter plugged into the Notebook and an electrical outlet to
recharge the battery.
Never turn off or reset your Notebook while the hard disk is in use and the HDD status
icon is lit; doing so can result in loss or destruction of your data. Always wait at least 5
seconds after turning off your Notebook before turning it back on; turning the power on
and off in rapid succession can damage the Notebook’s electrical circuitry.
Turning On Your Notebook Computer
Turn on your Notebook by pressing the power button. Hold the button down for a second or two
and release. The Power-On Self Test (POST) runs automatically.
After the POST is completed, the computer reads the operating system from the hard disk drive
into computer memory (this is commonly referred to as “booting” a computer). If your OS
(Operating System such as Windows XP…. etc) is installed, it should start automatically.
To turn the Notebook off, save your work and close all open applications, click on Start, then
select the “Turn off the computer”. A selection box will be displayed and click on the “Turn
Off” button to shut down your computer.
When your computer hangs up, press the power button for 4-6 seconds to shut down the
computer
