Using Your Computer for the First Time 7
Understanding POST
When you turn on your computer, a routine called POST (Power-On Self-Test)
automatically runs to test the computer components. Several messages appear on
the screen during POST.
Screen messages are built into the computer to report both normal and abnormal
system conditions. If an error message appears, take any action suggested in the
message. If the message identifies the error condition but does not suggest any
corrective action, write down the message and contact manufacturer or an
authorised service center for assistance. (See ”Troubleshooting” on page 111.)
Adjusting the LCD Display
You may wish to adjust the LCD (Liquid-Crystal Display) when you begin using
your computer. A TFT (Thin-Film Transistor) LCD does not require adjustment
for contrast because the contrast is set to remain at maximum.
To adjust the LCD:
•
Press <Fn+Right Arrow> to increase the display brightness.
•
Press <Fn+Left Arrow> to decrease the display brightness.
Turning Off Your Computer
If your computer has a Windows operating system, turn off
your computer by performing the shutdown procedure
described in this section. Otherwise, you may lose data.
APM(Advanced Power Management) mode
To turn off the computer:
1. Click Start on the taskbar.
2. Click Shut Down.
3. Select the shut down option.
