Dell xps 15 l502x graphis card blinks and i it doesn´t power up anymore until some intents

Hi,

I´ve a dell l502x and aboug 2 weeks I am having problems with the graphic card (I think). Sometimes the screen stops and then about 2-5 seconds it returns. But other times it doesn´t return anymore and if I restart the laptop then I am not unable to power up again (the button power led only makes a flash/blink). See my attached video.

(after connecting the power plug and try some more intents by pressing the power button during 5-10 seconds it finally powerup again)


Also, my laptop has two graphic cards (integrated intel HD 3000 and an Nvidia gt540M). I've 2 external monitors, so I've tried to connect them to the integrated and the external graphic card. When I try this it seems a funny game, sometimes one or two random external monitor (or my laptop screen) go down and then returns after a few seconds.

What can happens? Now I am updating graphic card drivers using the intel and nvidea repositories. But I am wondering that the problem is not related to drivers :S I am a bit afraid.

Now I am posting using my l502x laptop because it runs but perhaps in some minuts or a hour it will blinks again (it depends, somedays it's more often and somedays only 1 or 2 blinks).


Thanks!

 

Solved. It was related to mouse touchpad buttons. After unplug them all works again
