My HP Elitebook was working great till it shutted itself off. When I try to turn it on, the fan spins and the LEDs turn on (no blink), but it turns itself off after one second. When I plug in the charger, the charger LED on the laptop switches randomly, almost epileptic between orange and blue instead of the regular constant blue colour.
Previously I sometimes had a startup error in which the screen remained black and CAPS + NUM were blinking three times in a row (if I'm correct a memory error). Normally, I could easily resolve this by putting out the battery, hold the power button for 15 sec and put the battery back in. Unfortunately, this doesn't seem to be working anymore because of the immediate shutdown.
My questions:
1. What is possibly broken?
2. How do I fix this/what should I ask for in the computer store?
3. If there is no good diagnosis, how could I save the important files from my harddrive?
Thank you in advance
