My computer has no power and won't boot.

[Marty703]

My computer has no power and won't boot. I've done a Hard boot. I've checked the power outlet, power supply, and cables. I didn't damage the computer. It wouldn't boot this morning at the home office where it stays.

Does the power transformer have an LED that lights up?

Do any of the LEDs on the laptop turn on?

If answer is no you need to have it examined to see if power supply is bad or the laptops is bad.

If you see any LEDs turn on  or hear a beep or two then try holding \down the power button for a full 20 seconds.
