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 2nd 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?

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 Sep 21 '11 at 6:59
    
Do you have any solutions for it? even workarounds? – Muhammad Hewedy Sep 21 '11 at 8:35
    
at present, no...sorry. – RobotHumans Sep 21 '11 at 9:04
    
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... – RobotHumans Sep 21 '11 at 9:32
    
:S Can you point me to a place to start from? – Muhammad Hewedy Sep 21 '11 at 11:16

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.

Why would someone remove your answer? It is a solution to the problem, not perfect but a solution. – Joe Taylor Sep 27 '11 at 14:16
    
It solved the problem, thanks. but I really miss the ATI card! – Muhammad Hewedy Sep 29 '11 at 19:29
