Not sure what key i pushed, but all of a sudden the screen said "locking" and shut down.  Now I can't get it to restarr.

@Mo52 Alright, could have been a short cut key that put it into hibernation or shut it down, no need to worry though, I got you, let's perform a power reset as per HP standards:

• Ensure your laptop is OFF.
• Unplug all the external devices (If any).
• Disconnect the power charger from the computer, and remove the battery.
• Press and hold the power button for about 30 seconds.
• Connect the power supply (power adapter).
• Press the power button to turn on your laptop.
• Then put your battery back.

And if it doesn't turn back on, after the above steps are carefully followed, I suggest you check with an alternate adapter (borrowed from a friend or the local store) and also, check with another wall outlet.
