What type of laptop? What operating system?

Laptops don't boot for the following reasons: 1) Bad Power Cord. 2) Bad DC Power Jack where the power cord plugs into the laptop. 3) Static Charge Buildup. 4) Bad Motherboard.

The above 4 reasons are when you press the power button and absolutely nothing happens. You hear no fans running, no disk drive running, no one time clicking sound on the CD Drive and No light for a second or two when the CD drives click. In the case of a motherboard issue sometimes you will hear beep sounds or see blinking lights. Those beep sounds and blinking lights tells the technician what is going on with your motherboard and why it will not boot. If you see the blinking lights or hear beeps count them.

So you have a power light which means your power cord and dc power jack is good. So lets see if you have a static charge buildup.

Remove the Power Cord and the Battery from the laptop, then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back into the laptop, but leave the battery out. Press the power button to see if it boots. If it does you had a Static Charge Buildup and it's ok to put your battery back in. If it does not you more than likely have an issue with your motherboard.

You need to be more specific and tell what happens when you plug in the power cord and press the power button. There are a number of reason why a computer will not boot, but if you tell what's going on someone can help you.

Computers don't boot for basically the following reasons, 1) the power supply is bad. That means when you plug it in you don't see any lights, and when you press the power button nothing happens, you hear no fans, no beeps, no blinking lights, no hard drive spinning, no cd drive clicking and nothing appears on the lcd screen.

2) A motherboard issue, usually when this happens you will either see blinking lights or hear beeps. Those blinking lights and beeps are codes that tell the technician what is really going on.

3) Static Buildup - try removing the battery and the power cord then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back in (leave the battery out) and Press the Power Button. If it boots up you had static buildup and can replace the battery, count your blessings and Thank The Lord cuz a dishonest repairman would have told you he had to replace the motherboard for $300

One second after your press the power button or one second after it gets the the windows desktop? When you press the power button do you hear the fan running, see any lights, hear the disk drive spinning, hear the cd rom drive click once and see the light for about 2 seconds on the cd rom drawer? If all the previous is seen or heard it means you are getting power and it's trying to boot. If you see or hear nothing at all it means your power cord is probably bad. On most laptops once you plug the power cord in you should see a light someone on the laptop, if not the cord is bad. Also on some AC Adapter Power Cords they will have an indicator light on the adapter that lets you know it's functioning. It really sounds like your power cord went bad and the last time you were able to operate you were operating off your battery which is completely drained since the cord could not recharge it. One last thing to try is remove the power cord and battery from the laptop. Press and hold the power button for 30 seconds, then plug on the power cord back it and press the power button. if it boots you can put the battery back in.

When you press the power button do you hear the fan running, hear the disk drive running, see any lights, do you hear the cd drive click once and see the light come on briefly on the cd drive door? If you see all the aforementioned then it is surely trying to boot. Computers don't boot mainly because of the following problems. 1) Bad Power Cord or Power Supply. 2) Electro Static Buildup. 3) Bad Motherboard 4) Bad boot or system files.
Remove the Power Cord and the battery if it's a laptop. Press and Hold the Power Button for 30 Seconds. Then replace only the Power Cord and try hitting the Power Button. If it boots you had an Electro Static Buildup. If you have boot or system files that are missing or corrupt normally the system will be telling you that on an error message that appears on the screen. Does your system show you anything on the screen when you press the Power Button? If not you have a Power Supply or Motherboard issue.
