The problem did not appear in Lucid, but it does in Maverick. I believe it may be related to Graphics, because it happens when I do Video encoding or watch movies even though the CPU is far from 100%. So far my solution is simple: Remove the battery and CPU temp is about 20 C lower.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7523589.post-10275524832531148152010-11-10T22:23:49.411+01:002010-11-10T22:23:49.411+01:00Given that the fan isn't revving up, it's ...Given that the fan isn't revving up, it's probably not 'just crud', though cleaning isn't a bad idea. Before you start feeding your kernel boot parameters I'd suggest searching your distribution's package names for a 'laptop' meta package of some sort, packages that have your '$PROCESSOR' in the name, and the name and decryption in the package archive for your '$BRAND' of laptop (but probably not the model number).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7523589.post-14824675855001746932010-11-10T10:51:43.966+01:002010-11-10T10:51:43.966+01:00try adding the boot parameters 'noapic' an...try adding the boot parameters 'noapic' and 'nolapic' and see what happens.<br />http://en.wikipedia.org/wiki/Intel_APIC_Architecturejoethefoxnoreply@blogger.comtag:blogger.com,1999:blog-7523589.post-43246742799441926202010-11-09T17:52:12.454+01:002010-11-09T17:52:12.454+01:0090° is much too hot, even with slow fan.

On every benchmark i ever seen and on every test on my Notebook with Windows 7 my CPU Usage and so battery usage is much higher and so the battery lasts for a much shorter time.<br /><br />What distro are you using? I would recommend go to the IRC Channel of your distro and check how the kernel is build and what you can do.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7523589.post-25393504980396527252010-11-09T14:38:03.305+01:002010-11-09T14:38:03.305+01:00Try using other operating system, such as Windows ...Try using other operating system, such as Windows 7, which has a better support for ACPI and so on.
