I have a HP Pavilion that won't turn on at all. I have tried 2 different power cards (1 came off of a working HP Pavilion) but no luck. Serial No. 8CC52306V5 Product No. L9K83AA#ABA Model No. 22-a014 I have followed the direction from this video. I still had no luck. This thing is not turning on, no lights, no noise, no fan, no nothing. The warranty ran out August 2017 so HP won't help. The power cord that came with it, when plugged into the HP Pavilion, is making this wierd crimping noise over and over again. Like I said at the beginning I did try a different power cord that I know was working, but still no luck. I did check with a volt meter the power cord that was making the crimping noise and I am getting 19.5 volts. I think I have 2 issues a bad motherboard and a bad power cord? what now?
