i agree with pgwmw. i have and an 8540w i5 and it seems to be overeating. while rendering in cinema 4d and other similar applications it would shut down. but i general i find that it gets hot really fast. i don’t even know how this matter can be resolved. it even worse when i have an external monitor connected.

@pgwmw: That is unacceptable performance. Use your warranty. Sounds like maybe the heat sinks or thermal paste need to be looked at.

A very late reply, but owning a 8530w for some time I can first hand complain about overheating issues.
While performing ‘normal’ tasks, the gpu/cpu temperature is at a reasonable 50 degrees celcius. I believe that the problem is caused by a cooling problem with the containing nvidia chip. Even though it’s not a perfect card for 3D uses like playing video games, the amount of overheating it produces is beyond acceptable. Within 5 minutes of semi-intense use it will heat up all cores to over 100 degrees celcius and cause massive slugging and, when not supported by external fans, instant shutdown. I have been struggling with this problem for a long time, also because as to date I have found no way to manually control internal fans. Even though I’m not a regular gamer, i feel it’s a design problem. If you found more about the improvements in this aspect for later models, I’d be very glad to read more.
Kind regards,

(Also: I’m not a professional geek. Annoyance made me do quite a bit of research into the subject.)

Yup, review of the Elitebook 8440p coming up real soon. Sorry, it’s been a slight challenge trying to juggle real life (a lot of form filling and document compilation lately), HP news and another review (Battlefield Bad Company 2) at the same time, but expect the review to be up this week. I promise =)

I’m very interested in the 8440p, are you goning to publish a detailed review anytime soon?

When are you going to post all the benchmarks mentioned? I’m very interested in comparing the 8440p/w and 8540p/w…specifically to see if the NVS vs FX GPU’s makes much difference in gaming and how much better the FX is on Cinebench R10.

Thank you david and satein for the tips =)

@david, I’ll probably try swapping out my dv4′s RAM for my pal’s 8730w RAM and see if that’s the cause. I have noticed that the RAM area of the 8730w models in general tend to heat up a lot under heavy loads, but I never thought that would have been an issue.

@satein, In that case, I don’t think it’s a hardware issue – the notebook was able to power on immediately after the sudden turn off and it only happened very frequently with specific apps like Left4Dead 2 and 3Ds Max. Some other titles like NFS Shift worked fine without any issue (besides helping to increase temperature)

For a matter of suddenly switch off, not only CPU overheating can cause it, but also the chipset or graphic too. If it did switch off and need sometime before being able to reboot again. Overheating would be the problem. But if it did swith off and can reboot immediatly, probably it may be os, software, virus things… Hope this help.

I had a similar problem on my (ancient) HP pavilion zd7000, and in the end it turned out to be because of faulty RAM. Possibly combined with high heat.
