HP Pavillion dv2699 Verve Special Edition

Hi,

I am getting ready to look at a problem with my daughter's laptop above. She says it has been running hot for the past 6 months or so. When you power it up it turns itself off after about 15-20 seconds. I've looked through HP's website and it appears to have a power panel which I think could be the issue. I couldn't find anything about a power jack cable like mine has. I was going to start with cleaning the fan and heat sink but the manual indicates you pretty much have to disasemble 95% of the computer to get to it. I am going to start just by trying a new AC/DC adapter power cord.

Any suggestions, advice, etc, would be much appreciated.

 

Does the battery charge? So then without the AC plugged in what does it do then? Process of elimination.

How far in to the boot does it get in 20 seconds, see anything? And you said she uses it hot for 6 months, so does it eventually stay on?

Is that cold booting when it shuts back off? If a cpu shuts down due to over heating in that little time then there can't be any contact with the heatsink, maybe a screws come out of the heatsink or broken screw mount for the heatsink so its not contacting the cpu. But simply could be something else first. Maybe a BIOS thing or anything if its cold when you turn it on and its shutting off.

One more thing, if and when it does run can you use something like Speedfan to see exactly what the cpu temps are? Report back here. It might not be as hot as you think, and would eliminate heat shutting it down. If it is extremely hot then I can see the cpu shutting down to protect itself.

 

Thanks for responding. I am waiting for her to bring it to me. All I know right now is that she says it has beening running very hot, but still operating, for the past several months, and that now, when you power it up, it will shut off within 15-20 seconds. So, I want have any more info until I get it. She knows nothing about trouble shooting.

Thanks again.

 

Also, I was trying research issues last night and came across the Nvidia 8400 problem. Is there a possibility that this could be the problem? If I go through all of the tasks you listed and it still has the same problem, would it point to that? If so, would I need to replace the system board, with new graphics card and new CPU??

thanks again for your help.

 

To be honest I am not sure if the nvidia problem caused shutdowns, did you find that here? But I wouldn't doubt it does. I think people had a wide range of symptoms from the nvidia problem.

You should try plug a external monitor in to see if theres an image.

I have a dv9774 and I had to replace the motherboard due to the failed nvidia graphics chip. But what mine did was boot up and no image on the screen. I could hear the hard drive and the lights on the front. It didn't shut down, just stayed on with no screen.
Mine also never overheated at all. It just decided after 2 years of general table top use, no gaming, that it had to die.

I'd get the temps off it first, see what its getting up to when it shuts off. Start there. Try without AC to eliminate that at fault.

 

We have seen this before with other hp's. Something is failing right at startup of the computer, most likely the hard drive or RAM (the chips can unseat themselves occasionally )

One simple test she could do is try to start up in to the bios config instead of booting in to the OS. If it is a thermal related issue, it will still shut down, but if not there are ( i think) some diags in the BIOS that might be useful

Hope that helps
