Laptop getting hot

Is it normal for a computer to get hotter running linux vs. windows? I have a new laptop (inexpensive one) and everything runs beautiful with Red Hat and Mandrake except for the fact this baby gets HOT. The fan stays on constantly and it gets a whole lot hotter that when I run windows on it. Just curious if it is my puter or if that is normal.Thanks.

When the machine's doing nothing it shouldn't be like this. When running many apps - it's possible. You may see if APM is enabled. It may help.

Well aslong as it's stable you should be fine, just watch your lap. Some guy's laptop burned him awhile ago.

On my notebook, I thought just the opposite. With Windows my cooling fan would often start-up and buzz-away.

However with Linux, the fan only comes on occasionally - maybe once or twice an hour during normal use.

I would see if you have setup within Windows Power Management which may shut down items not in use thus lowering the heat. It may turn off the Harddrive or CD while not in use.

I do however wonder why if the fan is on constantly that the system would be hotter. I would make sure the computer fan is pulling hot air out of the computer.

I have a good idea why your feeling more heat with Linux then Windows. You are having a more enjoyable time using Linux and spend more hours within the Linux world.

Its typical of Laptops to run very hot in linux due to the lessening of the powermanagement features. Also, some latops won't run their fans unless acpi is on, or you actually tell it to run the fan...

Is it possible to install ACPI features to help keep the laptop heat down? I mean, I'd love to work in Slack9.1 as my native working environment, but if I have to worry about the computer possibly overheating I'm going to have to switch back to Windows, and I definitely don't want to do that!

I first had a superhot laptop ... burning hot ... installed ACPI ... cold laptop
it seems my laptop needs acpi to stay cool, don't ask me why (the fan always runs when I disable acpi ... ) and apart from that, apm won't work here

but acpi might save your legs here

Which distro are you running? Slack 9.1 has a bareacpi.i kernel image that I've installed, but the laptop gets hot and the fan always runs, just as you've described. Does anyone know if I can get ACPI running with this kernel? Or am I going to have to compile a kernel with a patch from

Perhaps, are there any configuration files I need to edit to ensure that acpid works properly? I've been searching through a lot of forums here but haven't found what I'm looking for, so any help would be much appreciated.
