Why is my power not turn on?

'No Power' issues are common with this laptop but can be traced to a few problems that I would check first before tearing into this laptop too much. What are the lights (located on the front left edge of the laptop) doing when you hit the power button? Do they come on or is nothing lighting up? If they do come on, you may have a 'no video' issue. If they don't light, try a new AC adapter. Most of the time the laptop will not power on if the AC adapter is faulty.
