Question about HP Compaq Presario V2000 Notebook
Laptop just shuts down without warning even when plugged in, battery or no battery.
My Presario R3000 laptop was doing this, at the same time bottom cover was also hot. So I got brave one day seeing as I had nothing to loose and pulled off the cover plates around the cooling fans.I dicovered the little air passages entering the main heat were blocked with what I can only describe as hard packed lint. This was causing the proccesor to heat past the built in temp setting. This is where you can start being carefull, The heat sink holds on with 4 screws with springs under them, take them out and and whatever else holds it on your model and lift the the whole fan and cooling block out, in that block where tyhe fan pumps the cool air into you will see the little radiatior fins plugged up, clean the the vents, if a fan is tight replace it for $3, Dont remove the proccesor if you dont have to, But if you just cant stop yourself like me, remember it only fits back in one way. You will see some grey stuff on the proccesor and where it touches the sink that looks like dried up glue, scrape it off carefully, you will need something like this for assembly, a compound like di-electric grease, the grease goes between the proccesor and the heat sink so the proccesor can tranfer heat properly. some dont use anything, but its better if you do. Put it all back together. Maybe someone on this forum has come up with a substitute for this heat grease, be gentle with things, and it really helps to have good quality screwdivers cause some of these sunk in screws you only get one chance with and they strip then then you gotta drill the heads off them and good luck finding screws with the special thread pitches these manufactures use.
when its done your computer will once again rock like only a teenager can....awe mech.

Interesting, the new Acer Aspire 5315 from Wal-Mart's Friday sale a week ago exhibits the same problem. I suspect it's a bad temperature sensor diode on the motherboard, or a faulty self-healing fuse. Otherwise, it could be a BIOS defect, where the cooling fan is not running fast enough or often enough to cool the laptop.

The DC connector needs to be resoldered on the system board.

You have a bad DC connector, which came loose from the system board:
