Startup Problems
When you turn on the computer, it does not respond and the Power
Indicator does not light green.
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.
If you are using the battery power, make sure that the battery is not
discharged.
When you turn on the computer, it stops after POST.
Restart your computer.

After you have performed everything as described above and still have
the incorrect date and time every time you turn on the computer, the
