Product: HP EliteBook 8440p Notebook PC

My laptop has LED lights above the keyboard area and they come on when I power it on, but the screen stays blank and the Num lock and Caps lock LED lights blink together 3 times, pause and blink again for another 3 times. It does the blinking for three times 5 times with 4 pauses in between. 

 

This is how it happened

I was using the laptop normally and went away to quickly get something done. When I got back, the screen was dark. I thought the screen just darkened because I'd left it on for a while but when I touched the track pad the screen did not light up. I long pressed the power button and it went off. When I put it back on, it started doing the blinking I explained above. 

 

This started a few weeks ago and my Dad took it for repairs. When he brought it back, it came on just fine. However, while I was using it today, the laptop suddenly did the same thing as the last time. The repair man did not tell him what the issue was so I can't even say what it is they fixed.  

 

Another thing is, my laptop can only stay on for 1 minutes and 15 seconds after I unplug it from the power outlet before it goes out. Anytime I use it I always have it plugged in. I want to know if this is what is causing the issue or if there's something else entirely.
