To check the power cables, and connections:
1.
2.
3.
If you have been using battery power, connect the Notebook to an external power source
and make sure that the battery has a charge.
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.
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.
If the outlet is controlled by a wall switch, make sure that the switch is on.
If the outlet is controlled by a dimmer switch, use a different outlet.
If your computer is plugged into a power strip with an On/Off switch, make sure the
switch is on.
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.

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.
Two classifications of malfunctions can be detected during the POST:
