I just got a Toshiba Satellite S40Dt-ASP4382S laptop, which does not turn on, I already removed all the devices, ram memory, hard drive, dvd drive, and the battery, and it is not solved, just turn on the power LED for 5 seconds and turns off. It should be noted that it has signs of fall and when connected to a VGA port to see if it is the video card, it does not show any signal. They could advise me to solve the problem. Thank you.

Hello Friend good afternoon . The problem is very common in Toshiba. The only thing you can do is send him to a place where you have a professional Rebaling The excess heat on the mainboard causes that failure ..... if you have experience you can do it yourself with a heat and pressure gun. The recommendation is that friend. best regards
