Basic Checks:
Test the electrical outlet: Ensure that the electrical outlet is working by testing it
with another device such as a lamp.
Connect the AC adapter directly to an electrical outlet: Bypass power protection
devices, power strips, and extension cords to verify that the computer turns on.
Check for interference: High-voltage electrical appliances on the same circuit or
operating in close proximity to the computer can cause interference. Extension
cords or too many devices on a power strip or multiple power strips connected
to an electrical outlet can cause problems.
