The CPU heatsync fan on my HP dv2000 went out. I purchased one on line and replaced it using HP maintennace documentation (thank goodness for that). After reassembly, the unit appears to be working correctly, at least from a hardware persepective. That is to say it gets through the POST and after a VERY LONG TIME, it finally displays the Vista login. I am able to put in my login creds and it starts up but again VERY SLOWLY. After bootup the eternally painful snail's pace continues. Clicking on menu items takes minutes to complete. Task manager (after it finally appears) appears to show no apps or processes consuming any inordinate CPU time or %.
I've reseated the memory, no luck
remove the CMOS battery and booted w/o it, no luck
reseated the hard drive, no luck.
I've even tried to boot using the recovery disks, the snail's pace is evident there as well. GRRR

- Stop Overclocking your CPU.
- Make sure your Heat Sink is placed properly above the processor.
- Clean the Processor fan, Heat Sink and other peripherals.
- Use High Speed fans.
- Use CPU Heat Sink Paste in the processor.
- Fix OS registry with reliable program like I always use Reginout.
- Shut down your computer at least two hour a day.
Best place to look is ebay. Look it up as a DV2000, as far as I know all the dv2000 series use the same cpu cooling fan. Otherwise, if you have the laptop apart, use the serial number or m/n on the part to look it up on ebay. I do this daily at my computer repair store and have lots of luck with hp laptop fans.
If computer turns off when idle, then check power saving settings, accessible from control panel.
If laptop turns off while you are using it, try first reinstalling the system to exclude system problems, or test the laptop starting OS from CD or staying in Bios settings mode, so to exclude installed system.
If laptop is still shutting down, then problem may be overheating.
Overheating usually happens when the fan is not coming , therefore when the computer overheats.Or the fan is not cooling enough and computer is overheating.
Monitor computer temperature using a software, check if Fan is coming up when temperature gets critical.
If fan comes up but does not cool enough, then replace the fan, it is not efficient anymore because of a bad bearing or dust. ~Also ensure that fan is well mounted, if fan has poor contact with CPU surface , cooling will be poor.
If fan does not come up, and critical temp is not detected, then the sensor on motherboard is bad, this is very uncommon. When this happens the problem is usually related to system or power settiings , rather than overheating.
If fan does not come up and temp is critical, then fan is faulty, replace it.
There are also more than one fan on many laptops, check that one of the fans (CPU fan, video fan) is not completely ded, and therefore cause for the problem.
By using the software below you can also find out if the problem is really overheating. If temperature results within normal range, then usually it is not overheating.In that case test systtem and check power saving settings.
Here is the software to control your fan and temp. sensor state:
First of all you need to figure out what might be hurting your HP's performance. There are a number of reasons that may causing your HP computer running
slow, but generally two factors: outdated hardware or poor system
maintenance. For hardware part: you can get more RAM, higher CPU etc.
For system part: there might be a lot of junk files, caches, errors etc
out there, about 80% slow HP issues are caused by this reason, in this
case you can rely on http://www.speeduphp.com/ to free detect and fix
if the fan does not work... don't use the computer till you replace the fan with one that is working.... a good chance you will burn out the cpu. usually thermal shutdown occurs when the cpu gets too hot... you may also want to consider purchasing a notebook cooler....
Yes! I would not recommend anything below 2GB at minimum. I have one laptop with 2GB and one with 3GB: they both open programs and browse the internet very quickly. Even with just two programs open (Internet Explorer and Outlook 2007) it uses 1.1GB of memory.
Just pick your model and they recommend the memory to pruchase. TIP: order with next day shipping - it's only $10. The free shipping takes 14 days. So unless you're patient (I'm not) the $10 many be worth it.
