 Make sure that either the AC adapter is connected or the battery has power.
 For models with the HDD heater option: When turning on the computer in an
extremely low temperature environment, the computer will heat up the hard disk
before starting up. The hard disk drive in-use indicator blinks red to indicate
the heater is on. (In conditions where the AC adapter is connected and the
temperature is above an acceptable range, the computer will display messages
on the screen informing you of the heating process; in other conditions, the screen
is simply blank.) Wait till the heating is finished. However, if external AC power
is not available and the remaining battery power is too low for the heating to
complete, the computer may not start up. In case the computer fails to start
up, turn off the computer and leave it in room temperature for about an hour
before trying to turn it on again.
When you turn on the computer, it stops after POST.
