DV1000 Overheating

Working on a DV1000 series Notebook for a friend.
She said it would intermittently shut down and she was getting a message from a temperature monitoring utility i installed some time ago called Notebook Hardware Control.
The message she said was the temp had reached 80 degrees Celsius and then it shut down.
I just ran an anti-spyware scan on it that took over 2 hours and at times the CPU usage was 60% or better.
The Fan did come on when the temp was around 50C and stayed on during the entire scan.
I saw the temp one time briefly hit 70C, but it averaged around 55-60.
She had been having this problem for quite some time and seems to think its getting worse.
I haven't seen it shut down yet and im debating on whether to disassemble it and clean off the Heat sink for the CPU and apply some arctic silver. I have seen several posts in other discussion forums about this same problem, but no one seems to have resolved the issue other than sending it out to HP for a costly repair.
One person mentioned upgrading the BIOS, but i didnt see anything in the revision history that said anything about fan or temp control, not to mention HP's ftp site seems to be down now for the last 12 hours.
She said Circuit City wanted to charge her $500 to send it out and replace the fan. The fan seems to be working fine, so im not sure why they would tell her that. (other than to make money)
Does anyone know if a new upgraded fan and or heat sink exists for this and if not, does anyone think cleaning off the existing heat sink and reapplying some arctic silver will help?
Any other suggestions welcomed.

 

That shouldn't be at all a debate. It's very clear that this machine is suffering from overheating, and it's most likely due to clogged fans/heatsink. If she has never done this since she got the machine, then it's long long overdue for a cleaning.

I had mine for 6 months, and when I took it apart, there was a quarter inch think blanket of dust completely covering the heatsink. I can't imagine what her's looks like after 2 years I'm guessing she had this.

 

I agree you need to make sure all your vents are clear of dust and also get a cooling pad

 

Take the computer apart and clean it. If you don't know how, get the Maintenance and Service Guide from HP's website ( www.hp.com > Support & Troubleshooting > [enter product number] > Manuals.

Be sure to observe the ESD precautions in the manual!

 

You also need to find out exactly how she was using it when the problem occurred. My guess is that maybe she was using it on her lap, carpet, on the bed, on the couch, etc., and that was blocking the cooling vents? Just a guess but if you were thrashing the hard drive running tests and it didn't get up to 80, then something must have been wrong in the previous environment.

 

Thanks for all the replys folks.
I did warn her last year when she said it shut down once in a blue moon, that she shouldn't use it while in bed or on anything but a flat surface.
I suspect for the period she used it in bed, and the few times she probably didnt heed my warning since, that the subsequent overheating may have possibly warped the heatsink and or trashed any heat sink compound that was there from the factory.
Im able to look in with a flashlight and dont see much dust build up at all around the fan blades and when i look in the rear exhaust port i dont see much there either.
I have the disassembly guide for it and even though ive disassembled a few laptops in the past, its not one of my favorite things to do.
I guess i posted here, just so i could here the inevitable from a few of you.
I have one of the Antec laptop coolers for my Lenovo laptop and it really didnt make much of a difference in temps. I just use it as a flat surface when im on the couch or recliner.
Any recommendations on something she could use while in bed or on the desktop that might even lower the temps some?

 

Hey guys,

I signed up to this site just now specifically for my dv1000 laptop. But see that there's more to this site than notebooks / laptops, there are posts about pda phones and cameras! I'll be sure to check this out again!

Ok, on to the problem; my laptop overheats and suddenly shuts off. When it does that, it may be offline for a few hours to a few days! I don't know exactly how that works inside... Everyone says it's about the fan that doesn't cool the inside enough. I've taken steps to elevate the laptop towards the back, and even bought a cooling pad.

The problem is still there, as of last night. I've noticed something though, The plug may be the main source of overheating. When my adapter is plugged, the side of the computer near the power jack gets awefully hot! When I unplug the adapter, the notebook cools down. I only had somehting like 45 minutes of battery power, so I replugged the adapter and that overheating sarted all over again... So I did that process over and over again throughout the evening. Effective but kind of annoying.

So how do I fix this? Should I change the power jack? Is this pure coincidence?

I would really appreciate a heads up on that.

Thanx

 

your notebook is at least 2 years old. have you even cleaned out the fans once?

I do not think its the power jack, but an underlying cause is influencing it to heat up

 

Hmm....

Cleaning the fan... How do I do that? Should I use a high compression air can or is there a way to open it up to get to the fan???

As I write this, I actually hear the fan running intermitently under the notebook. And the side is still hot. Time to unplug and replug later.

By the way, what do you mean by "underlying cause"??

thanks for he info

 

To clean the fan, check my earlier post in this thread.

I think that may not be your problem, although cleaning the fan won't hurt. Forgive my bad memory, but I seem to recall some older HP notebooks had problems with their power jacks coming loose from their solder joints or the center pin breaking, resulting in intermittent power and/or sparking across the broken joint. I can't recall if the DV1000 was one of these.

I also seem to recall there may be problems with the voltage regulators on the motherboard overheating and failing. I suspect this may be your problem. If you have the skills to diagnose and fix this, great, otherwise you're in the market for a new notebook as a repair is not going to be economical.

Oh, one other thing to check, does it heat up like that with the battery out? Maybe there's something wrong with your battery.

 

Hey Jimbo,

I've tried a lot of things now and it still doesn't work. First of all, I finally got a cooling board for the computer. It worked great! The computer was staying cool anough to run for extended periods of time. Although this was just evaluated by touching, and the laptop stayed cool. I didn't know where to get software to view the temperature of the device...

Well, that didn't last too long. For some reason, it shut off and gave me the problems all over again. Weird though. When I was able to get it runing again, I tried the notebook without a bettery and it seemed to work. I went to run an errand and about an hour later I came home to find the problems happening all over again.

A friend of mine told me to order a new pin for the adapter. He's no genius, but thinks that may be part of the problem. So on that you may be right.

What I find odd is that connected or note connected with the adapter, sometimes I have to play with the battery (snapping it in and out repeatedly) until the computer starts up again...

I haven't cleaned out the fan and the heatsink board. It seems a bit complex and I haven't found nice visual instructions to do so. Maybe you'd have a link to a site that has???

Thanks

Phil
