i.bakar Posted June 6, 2022 Share Posted June 6, 2022 well i did something very stupid yesterday , i opened the screen cable from the screen side while the laptop was on and small part of the connector got de-attached and when i tried to attached i think it shorted something so the laptop went off ... i immediately removed the power adapter from the laptop and then opened the back and remover the battery . and the motherboard small lithium battery as well. after a few minutes i connected the power to it and try to start the laptop put no signs of life !!! here is the steps i toke to diagnose the issue : - i disassembled the full laptop and removed the both gpus, the processor, all the 4 ram slots to see if any of them is causing the short , then connected the power button cable and tried to start ( nothing ) - i checked the power adapter to see if the green pulp is going off when its connected to the laptop but its stays on ! (which means to me there is no short ) - i conneted every thing back together and connected the power adapter to the laptop to see if any of the internal components will short the circuit but the green light stayed on ! (which means to me there is no short also) - i tried to do the static drain ( remove all power and batteries and push the power button for a minute ) but nothing happened ! - i thought maybe the poer button went bad so i got a multimeter and i checked the connection between the button and the motherboard while the button is pressed and released but its working fine. NOTE : when i say nothing is happening i mean literally nothin ( no lights no fan start no any signs of life! any idea or suspicions from anyone is highly appreciated thanks Alienware M18X R1, i7 2960XM @ 4.4Ghz, Nvidia GTX 880M SLI , 32GB RAM , samsung 840pro + samsung 860evo ( THE BEST I EVER HAVE) Alienware Area-51M R1, i9 9900K @ 5.1Ghz, Nvidia RTX 2080, 64GB RAM, samsung 980 Pro( LOVELY MACHINE WITH BAD BIOS ) Alienware 18 , I7 4930MX @ 4.2Ghz , GTX 980M SLI, 32GB RAM ( MAY REST IN PEACE) (CAME BACK TO LIFE) Link to comment Share on other sites More sharing options...

razor0601 Posted July 7, 2022 Share Posted July 7, 2022 I think the short is on the motherboard side. You have to take the laptop apart. And have a look at the lvds connector.
