Collected some random links about high pitch noise from the computer that could relate to this issue. In windows I hear the high pitch regulator noise and the battery life span is much higher. However, I recollect hearing the same sound with some previous version of Ubuntu. Those Ubuntu versions felt like being more power conservative.

Confirmed for a month... Is anybody working on this?

koopee, 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 computers running hot. 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.
