Following an electrical problem that occurred during my absence, my HP Pavilion DV6500 AC no longer works . It was plugged in and turned on without battery when the problem occurred . Since it no longer works on battery , and it does not load when my computer is plugged in , which is very problematic. I went to a computer to test my power cable, what it did to me and even with that other cable , nothing worked . They said there was certainly something that had blown ( like the fuel system ...), and it would be very expensive to replace or repair, it was better to buy a new system. Please help.
