I took it into a repair shop and they said powersupply wasn't working and possible cmos or bios needed to be reflashed. It worked fine with another powersupply three months before I was using my old GigabyteP55Wv4 powersupply https://youtu.be/A_niIDt3_H4 but I gave that stuff to my sister with the laptop. I haven't tried to use a replacement powersupply with more amperage or wattage. I also summited it to tronixfix but had no response.

thanks
