Hi, If you have one of the newer laptops where the battery is not removable, do the following:
1. Make sure the unit is turned off. 2. Plug in your power adapter to the computer and the wall socket. 3. Hold down the left-side shift, control and option keys at the same time as you hold down the power button. 4. Release all keys/power button simultaneously. 5. Wait a few seconds then press the power button and see if it turns on. This process is a last resort and should only be done after you've tried a number of things. I assuming that due to the fact that your Mac will not power up, the other things are not available to you. What this process does is reset the System Management Controller (SMC) which controls battery management, power button control and a number of other things which can sometimes, in rare occasions get confused. If this process does not fix your issue, you'll need to send your unit in for service. Also, if you have a desktop unit instead of a laptop, there is a different process that will have to be applied.
