Last night I was using my hp G60-6350dx and the battery was fully charged when I turned it off, now today, I tried to use it and it did not turn on.  It will not even accept the ac power.  I only get three blinks.  Does anyone know what I should do?

Overview of How to Troubleshoot Problems When a Computer Does Not Start Up or Boot Properly

http://h10025.www1.hp.com/ewfrf/wc/document

DO THIS FIRST - Perform a hard reset

If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.

1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.

You may have to remove and reseat the RAM, one or the other may be bad.

You can try only 1 at a time and see if they are bad.

Only purchase MATCHED pairs of ram, always in a sealed package, and run MEMTEST on new hardware to check if its faulty and have to return it, http://www.memtest86.com/ any other testing software will do as well.
