Problems when you turn on the computer
These problems may occur when you turn on the power.
The computer will not start.
Make sure you attached the AC adapter and power cable properly or
installed a charged battery.
Press and hold down the power button until the on/off light changes to
green.
If you are using the AC adapter, check that the wall outlet is working by
plugging in another device, such as a lamp.

You are probably in Standby mode and have a software or resource

Alt, and Del simultaneously, select Shutdown, then Restart to restart the
computer. Read the documentation that came with the conflicting device

If the problem occurs when both the keypad overlays are off, make sure the

software’s documentation and check that the program does not assign
different meanings to any of the keys.
