THE COMPUTER DOES NOT START OR BOOT-UP
If the power indicator is not on, the computer is without power. Make sure you
have properly attached the AC adapter and power cord, or have installed a
charged battery.
If the computer is running on battery power, ensure that the battery charge is
not low. If the battery appears to be charged, it may be faulty.
If the computer is using the AC adapter, ensure that the AC outlet, airplane
seat jack, or car cigarette lighter are working. If the AC outlet power is working,
the AC adapter may be faulty.
H
ARD DRIVE OR EXTERNAL BOOT-UP DEVICE IS INACCESSIBLE
If the hard disk indicator is lit, BIOS may be incorrectly set. Revise the BIOS
settings for the Primary Master.
Security may be set to prevent starting the operating system.
If you choose to boot up your system from an external device through a USB
port, make sure it is on and bootable media have been inserted.

HE SCREEN IS BLANK OR THE DISPLAY IS ABNORMAL
The computer may be set to an external display device only. Press Fn + F1 to
switch to the VM display.
The power management system may automatically blank the screen to save
power, and is in video time-out, standby mode, or hibernation mode. Press any
key, move the pointer, or push the power button to turn on the display.
The angle of the display and the brightness level is inadequate for the ambient
lighting. Adjust the display angle and press Fn + F2 or Fn + F3 to adjust the
brightness level.
The LCD screen has a default resolution of 1024 x 600 (XVGA). If you set the
resolution lower than this, the screen expands to fill the display. When the sys-
tem can not expand its display to full screen on the LCD screen or on an exter-
nal display device, you can right click on Windows desktop and select
Properties to open the Display Properties window. Then click the Settings
tab and set the resolution to an appropriate value.
