4. If you are using the Notebook with the AC adapter, check the power
outlet, the power cord, and any power switches that may affect your
computer.
5. Check the wall outlet or power strip with an item that you know is
functioning properly. A lamp or radio is a convenient item for
checking the power. You may also need to check the fuses and
breakers in your electric box.
6. If the outlet is controlled by a wall switch, make sure that the switch
is on.
7.
If the outlet is controlled by a dimmer switch, use a different outlet.
8. If your computer is plugged into a power strip with an On/Off switch,
make sure the switch is on.
9. With the computer’s power switched off, check all cable connections.
If the computer is connected to any peripheral devices, look for loose
or disconnected cables.
If the computer is too close to a wall, a cable connection may be loose or
the cables may be crimped.
Do not substitute cables for different devices (other
than the manufacturer recommended cables) even if they look
exactly alike. The wiring inside the cable may be different.
10. When you are certain that you have power available and all
connections are good, turn the computer on again. If the computer
still does not start, you may have a hardware problem.
The Power-On Self Test
The Power-On Self Test (POST) runs every time you turn on or reset the
Notebook. The POST checks memory, the main system board, the display,
the keyboard, the disk drives, and other installed options.
A few seconds after you turn on your computer, a copyright message
appears on your display screen. A memory test message appears next; as
the test continues, memory size increases until all installed memory is
tested. Normally, the only test routine visible on the screen will be the
memory test.
