Hi all, I managed to isolate the issue due to the amount of light blinks if any you see when you first try and turn the laptop on. I have a Dell XPS that has the exact same problem noted above, not sure if HP machines do to the same to help with diagnostics however my machine beeped or flashed a small light where the usual HDD & PWR indicator lights are usually found, 5 times from memory, 3 long and 2 short….something like that. When I checked further into Dell trouble shooting, the beeps translated into a CPU issue, which unfortunately it did turn out to be….hope this helps
