LG Viper won't turn back on?

[Brett Wilson3]

I've had my phone for about 4 months, and it's been working perfectly. but randomly, it just won't turn on. I'm positive it wasn't out of battery, because i plugged it in and it still won't turn on. help?

Welcome to Android Central! Try holding the Power button down for a good 10-15 seconds.

Even though your phone is relatively new, take out the battery, lay it flat on a table, and try to spin it. If it spins freely, that means it's bulging in the middle, which means it's going bad. Any battery can be defective and fail early, so it's not out of the question.
