Startup Problems
When you turn on the computer, it does not respond and the Power
Indicator does not light green.
z If you are using an external AC power, make sure that the AC adapter is
correctly and securely connected. If so, make sure that the electrical
outlet works properly.
z If you are using the battery power, make sure that the battery is not
discharged.
z As a protection, the system will not start up if the temperature is too
high. If this happens, both the Power (
) and Battery Charge ( )
indicators blink green for 10 seconds. Wait till the temperature drops
down before trying to turn on the system again.
z 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. Both the Power (
) and Battery
Charge (
) indicators blink green at the same time to indicate the
heater is on. 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.
