When I plug in the power cord nothing happens. I press the power button and nothing seems to happen. I tried 3 different cords.

press the home button while it is plugged to the usb cord

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

Hi,

Welcome to FixYa!

It seems that you are having problem with the LCD on the laptop. This may cause by an electrical charge in the motherboard itself,Im not really sure how it affects the display of the computer.There's also a possibility that the problem is with the LCD cable or the LCD itself. Please follow this method since it usually fix such problem like that,

1.Removed the battery then unplugged the AC adapter

2.Press and hold the power button or the ON/OFF button for at least 30 seconds

3.Connect the power supply back to your computer then turn it back on.

4. Check if you will see any difference.

5. If nothing happens, try to press and hold Fn and F2 on the keyboard.

If nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...

I hope this information will be helpful. Thank you for using FixYa...

Your battery maybe out of charge. Thats why nothing happens when you press the power button. The battery may not be charging because the power cord might not be working. Try another power cord.

Try removing the battery and plugging the power cord and switching on the computer. If its the problem with the power cord the computer wont start. If it starts, the power cord is working fine.

It seems like a motherboard issue. It heats up, thus is not able to turn on continuously. You may need to check internal parts embeded on the motherboard llike the fan and processor before you could know what needs replacement.
