My HP ProBook 4530s got much hotter with Ubuntu Linux than Windows 7

Question

I have a ProBook 4530S with Windows 7 on it. I've got the software drivers from here.

I just installed Ubuntu 11.04 x64 on it. I am noticing that the notebook became much hotter, even after installing the ATI Driver (which I got from ATI website)

Are there any drivers that I need to install? (It's Intel 2^nd Gen Core i5)

According to the driver site from HP, there are not many drivers related to the chipset that I need to Install – just the ATI driver, which I already got from the ATI website, and the Intel VGA driver.

Here's the result of lspci:

Is there anything missing?

Solution

I've got the same problem. Disabling discrete graphic from BIOS did the trick. Now the fan is regular.

I hope my answer is useful for someone that can work on discrete graphics integration with ubuntu, or help someone that is formatting just because having fan always running.

I experience the same thing with my hp dv7 with an nvidia card. I think it's a glitch with power management in the general driver...like it doesn't distinguish between desktop and laptop cards w/ and w/o on card fans.

[RobotHumans]

at present, no...sorry.

[RobotHumans]

i haven't tried it, but you might be able to hack something together with manually setting your main fan to a higher constant speed...

:S Can you point me to a place to start from?

acpi parameter manipulation seems the way to go...here's a brief discussion: forums.fedoraforum.org/archive/index.php/t-66328.html

Why would someone remove your answer? It is a solution to the problem, not perfect but a solution.

It solved the problem, thanks. but I really miss the ATI card!
