Checking Cables and Connections
Start by performing a careful visual inspection of the exterior of the computer. If no LEDs are
illuminated, make sure that your computer and its peripherals are getting power and communicating
with each other properly.
To check the power cables, and connections:
1.
If you have been using battery power, connect the Notebook to an external power source and
make sure that the battery has a charge.
2.
3.
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.
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.
