Hi, in this video, I demonstrate how to diagnose and fix HP laptop ProBook 440 G3 that doesn't turn on due to a short circuit capacitor on the motherboard. This is a common problem in almost all laptops, I used a multimeter to measure for short on DC input, and a power supply to inject voltage to easily identify a short hot capacitor.
I was able to fix the motherboard however it turned on with no display, the caps lock and num lock were blinking 5 times which is probably a corrupt Bios problem. I will make the next part when programming its Bios and upload it here.
Otherwise, thank you for watching, and don't forget to subscribe.
