The Dell XPS 15-L502X laptop was manufactured by Dell Inc. It was released in 2011 with a 2nd Gen Intel® Core™ processor.

My Dell wont turn on, but everything is good.

Well, let me resume the most part, i think my dell laptop may have a faulty Graphics card, since when i turn it on, the fans keep blasting but no image neither boot will happen, it will only stay there with its fans compleatly on, but cooling nothing. i dont think it's the bios, since SOME times it decides that it will boot, its not the ram since i swapped them out and tested each slot and both work, my processor is not it since it would NEVER boot (i think), its not bad pheriperals since nothing is plugged, not the battery since it died years ago and i removed it, maybe the charger since its 90W, but its official still, not power button cables and not unnaligned flex cables since i replugged every each of them i could without just mangling my laptop (i hate to dissasemble it since its an HELL of a work to do so), someone knows something? not even an error code it throws, just fans blasting without every shutting down, i can only shut it down when i hold the power button.

Hi @luanhenriq10963

Can't see that you mentioned trying a power refresh by removing the coin cell battery from the motherboard in case it is a corrupted BIOS that is the cause of the problem. If you haven't here's what to do.

Disconnect the power from the laptop and then open the laptop (you don't have to remove the battery as you said it's not there) and remove the coin cell battery from the motherboard.

Here's the service manual for the laptop. Go to p.37 to view the procedure to remove the coin cell battery from the board.

Once it has been removed, measure its voltage. If it is <2.5V DC or if the battery is >4-5 years old, replace it. The battery type is printed on the battery e.g. CR2032.

Press and hold the Power button operated for a full 30 seconds and then release it.

Reinsert the coin cell battery (+ve on top as marked on the battery), reassemble the laptop, connect the charger and check if it starts OK.

If it does there may be a message stating that the date and time are incorrect. This is normal as the BIOS has been reset back to factory default by the above procedure. Once the date and time have been corrected, the message won't appear the next time the laptop is started. Also any user definable BIOS settings, changed by you to suit whatever operating requirement you needed, will have to be changed back again also.
