  3. Press and hold the power/reset button for 8-10 seconds.
  4. Plug in the AC adapter (check that there is some indication that the laptop is getting power. This will vary depending on the make and model. Most laptops have some sort of power light.)
  5. Try holding down the power/reset button for 8-10 seconds.
  6. Release the power/reset button.

Mac Laptops (iBooks, PowerBooks)

Mac laptops usually have a colored ring where the AC adapter connects to the laptop, this is green when the computer is on, or when the battery is fully charged, or orange when the computer is off and the battery is charging.

Sometimes Mac laptops won't boot and it's necessary to reset the Power Management Unit. For instructions on how to do this, go here: http://docs.info.apple.com/article.html?artnum=14449#faq10 If you first remove the battery, on the inside of the casing you will find the specs of the machine including the Processor speed so you will know which set of instructions to use.

You can also try resetting the PRAM and NVRAM on Mac laptops Operating System#Keyboard_Shortcuts shows you which keyboard shortcuts you'll need to use while booting.
