Plug in the charger and leave it alone for about 4 hours. Then try to turn it on.

Welcome to Android Central! Which phone?

After letting it charge for at least 4 hours, as Rukbat mentioned, you might also have to press and hold Power for about 15-20 seconds.

Which phone? Potentially look to do a hard reset.
