Can we please have some action on this? This should really be a very straightforward change to integrate.

But Dell Inspiron 1545 is listed on Ubuntu-certified hardware list: http://www.ubuntu.com/certification/hardware/200910-4252:200911-4633:200912-4896:200912-4897
So I don't understand, why ubuntu is not working with this laptop properly. I have the same machine and I also have problem with overheating(on 10.04,10.10 and 11.04). I tried adding acpi_osi=Linux to the kernel boot options in /etc/default/grub but it didn't have any effect. Laptop is usable, but hdd is reaching 50-60 degree which is definitly not OK. I'd really appreciate some action here. I bought this laptop, because it's listed as "ubuntu certificated" so I believed it will worked flawlessly "out of the box".

Ben Gamari, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? As per https://wiki.ubuntu.com/Kernel/PowerManagementASPM a patch has been issued to address high system temperatures. Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

This is still a problem. I'm on Ubuntu 12.04 and started a thread one year ago about this issue here: http://ubuntuforums.org/showthread.php?p=11915945 .

Basically temperature idles around 50 degrees and on average use bounce up to around 60. I haven't tried any intensive tasks yet.
From what I've noticed the fan always seem to run at the same setting and never boosting up or settling down. However 50 degrees is 10 degrees higher than Windows 7 during low CPU load.

If there's anything I can do let me know.

Thanks!

There is one thing that helped me with this problem. You can set lower APM value with sudo hdparm -B 128 /dev/sda (default value is 254). After this your hdd should stay around 40-48 degrees. But it's not solution, because with lower APM value your hdd will spin down/up quite often, therefore load/unload cycle count will be extensively raised.
