I would check to be sure the power cord is securely attached, both to the computer and to the outlet. If you are hooked into a surge protector or outlet adapter, but sure it is on and not in need of being reset. Then be sure the wall outlet is working (plug in a lamp or radio or something). (Be sure,too, that your screen is powered on - I have had people who thought their computer was off when it was just their screen was not turned on!) If everything appears to be working and plugged in and your computer still will not boot up, I would either call a service technician, or carry it in to be checked - it could be the power supply inside of your computer box.

First, try pushing the off button. if that doesnt work u probabley locked your phone so that's why it wont turn off. Just unlock it but don't take the battery out. u can but i don't recommend it.
