Chapter 2: Before you use your Notebook PC
21
2-3 Power on
Press the power switch on the keyboard to turn off your Notebook PC. You
can turn off your Notebook PC simply by pressing the power switch longer than 2
seconds.
As soon as you turn on the power, you can see a series of diagnostic tests on
the screen, which are controlled by software. These are known as POST (Power
On Self Test). Press the <Esc> key and you’ll see the test results on the screen,
including the CPU model, BIOS version, hard disk, memory test, etc. of your Note-
book PC. POST procedure is activated each time you turn on your Notebook PC.
POST records the basic information of hardware. You can set the basic
information via BIOS (Basic Input/Output System). If the information contained in
your hardware is not the same as the original information, POST will display a warning
message and ask you to enter into BIOS to change the setup. If you intend to
change the setup of hardware, you can press <Alt> + <F2> keys to enter into BIOS
for this purpose.
Your Notebook PC has been installed with an operation system before ship-
ment and all defaults are correct. As soon as POST is completed, your Notebook
PC proceeds to the operation system.
The hard disk of your Notebook PC is installed with S.M.A.R.T. If the hard disk
detects an error in the self-detecting analysis during the POST test, a warning
message will be displayed. In such a case, please copy the important data to the
expanded hard disk or diskettes immediately. After you make the backup copy, please
contact the authorized distributor.
If your Notebook PC is not installed with an operation system, you will see
“Operating system not found” on the screen after the POST process is completed.
This message tells you that the hard disk has been detected, but no operation
system has been found in the hard disk, floppy disk or CD-ROM. You can start
installing the operation system after you see this message.
Do not remove the power cord when the hard disk, floppy disk or CD-ROM is retrieving
data. Otherwise, you may lose important data or even destroy your diskette device.
Please follow the procedure of the operation system to turn off your Notebook PC
when the operation system is working.
