    Unfortunately for me, I've tried all of that on my laptop, which is the same model as in your video! I notice your website is now offline. I had no mains power/battery charger light, and no power button light either. I went to a Restart Party (electronics repairs) https://therestartproject.org/ where I did most of the work dismantling the laptop, although we left the motherboard in place and didn't touch the screen assembly. I removed the battery, the hard drive, the memory, the keyboard, the lower cover, and even the WiFi card! At the end, I had the power jack/battery charger light coming on, the power switch light had come on briefly, but then stayed off. After the party, charging the battery back at home, the laptop still wouldn't turn on and there was no power button light! When I plugged my phone into a laptop USB socket, it started charging. I can only think of two possible solutions. These are 1. Somehow bypass the power switch. This switch can cause the laptop to be turned permanently off. Unfortunately, when the cover containing the switch was removed and the charger was plugged in, the laptop didn't automatically turn on. 2. Replace the motherboard. Unfortunately, some motherboards for sale seem to be missing components and I saw one which was described as for this laptop, but was Intel based, although mine is AMD.

    When draining voltage (remove battery and pulse power button) sometimes it takes holding the power button down for a full minute to drain capacitors.

    My Compaq Presario CQ62 came with win 7 upgraded to win 10 and upgraded memory from 2 gig to 4 gig two memory cards inside, power cable is good it works the light on the side of the pc lights with cable pluged in but power button fails to power on, i tried to pull off battery back panels removed mem cards and reinserted still no power so i have pulled apart what I could of the laptop but could not get it to separate from case so i took out the hard drive but i want to know how to get this hard drive to work on another laptop i know i have to get some kind of usb connector but the type of drive is samsung Model HM250HI ATA type i think and i wanted to just use it as an external drive to use as back up, not sure what i will need as the connection on the drive is very different no pins just slide type connector
