My HP Pavilion zv5000 has worked well for at least 3 years. The battery failed over a year ago, but I have been using it primarily on mains power and it has been fine until this week. Over the past few days, it has been turning itself off, after short periods of time, for no obvious reason. It will now not start at all. Power is getting to the back of the machine OK, as far as I can see from the charging light up front, but when I press the "on" button, nothing happens apart from a brief flicker of the other 2 LEDs up front. Any ideas please.
Thank you.

Have you cleaned or blown out the ventilation ducts and grills since you have owned it. If you haven't, there is the possiblility that the thermal paste has been baked off the processor and there has been damage done to the motherboard. The laptop will run fine with no battery installed. Get a few cans of compressed air from an office supply store and using short bursts of air, blow out the grills and all the compartments. If there is easy access to the heatsink, most likely that needs to be pulled and cleaned, as well as the processor and new layer of thermal grease applied. Remember though, if it isn't powering up at all, there could be the possiblility that the ac adapter is no longer putting out the correct voltage to power the system up efficiently. Have your power supply tested, to make sure it is putting out the correct voltage under load.
Testimonial: "Thanks Parrothead - I'll try all of these. I haven't cleaned it out since new, so that's an obvious start. Will update u after testing the ac adapter"
