Often when a laptop won't power on, it's because of one of four things: the battery, the battery charger/AC adapter, the power board/battery charging board (if the laptop has one), or the motherboard.
You can attempt to rule out the battery by attaching the AC adapter and trying to turn the laptop on. If the laptop turns on when on AC power but won't turn on with the battery, then one of two things is happening: either the battery is bad, or the charger is bad and the battery has run down. If the laptop won't turn on with or without the AC adapter plugged in, then the battery is not the problem. If your AC adapter has an LED on it, you can often tell if the adapter isn't working because the LED won't light up. (However, just because the LED does come on doesn't mean the adapter is working as it should.)
If it doesn't seem to be either the charger/adapter or the battery, then you're probably looking at either the power board or motherboard. If you are comfortable taking the laptop apart, you might want to try replacing the power board, which is the board that the charger plugs into. Amazon.com sells power boards (also sometimes called power jack boards) for many laptops for between $15 and $30.
The motherboard is a more expensive option to replace, so a good rule of thumb is to try the less expensive parts first. If it still won't power on, you may have a bad motherboard, in which case it might be cheaper to get a new laptop than have the motherboard repaired or replaced.
