The computer will not start
Make sure you attached the AC adaptor and power cord/cable properly or 
installed a charged battery.
If you are using the AC adaptor, check that the wall outlet is working by 
plugging in another device, such as a lamp.
Verify that the computer is on by looking at the Power indicator.
If the indicator is glowing, the computer is on. Also, try turning the computer 
off and then on.
If you are using an AC adaptor, verify that the computer is receiving power 
from the external power source by looking at the AC power light. If the 
indicator is glowing, the computer is connected to a live external power 
source.
Hardware and system checklist
This section discusses problems caused by your computer’s hardware or 
attached peripherals. Basic problems may occur in the following areas:
Power 
When the computer is not plugged into an AC power outlet, the battery 
pack is the primary power source. However, your computer also has a 
number of other power resources, including an intelligent power supply and 
a Real Time Clock (RTC) battery, all of which are interrelated with any one 
having the ability to produce apparent power problems.
Overheating power down
If the processor's temperature reaches an unacceptably high level with 
either setting, the computer will automatically shuts down to prevent any 
damage - in this instance all unsaved data in memory will be lost.
