hi all I recently had some great advice with a previous prob heres the new one!!
ok i installed ubuntu 9.10 on my partners laptop she is loving it instead of windows but after about 20 mins or so it completely shuts down. we both totaly new to linux. I read somewhere that i need to configure cpu control is this true? and if so how do we do it? thanks in advance.

Perhaps it's some kind of bug. But in general it shouldn't be something you HAVE to do you just can do it. First of all check lm-sensors and see is it because of heat or something else. Maybe command dmesg will show us something interesting.

Perhaps they already solved this one but some time ago UBUNTU was destroying disks because trouble with power savings. To do it manually use hdparm.

I think the best shot to start in fact is acpi. So look around how to disable it using grub. If I remember right without acpi I had to shutdown system than push power button to tern it off. Although for now we just want to know what is wrong...

it gets really really hot!! hotter than it ever did using vista then just turns off i have taken back off and cleaned fan with a usb hoover but it doesnt kick in when its on

It took me five seconds to find what you suggested just try http://ubuntuforums.org/showthread.php?t=77497
In last post you have command....You should also have gnome applet shoving CPU speed.
And learn to use google.

im afraid thats not too helpful demerzel and yes I HAVE googled this and researched it for quite a while!! what do you mean it took 5 seconds to find?? as i said previously we new to linux dont you remember the probs when you started?? id appreciate a less condessending attitude and a better explanation of how i solve it??

heres solution it worked
you need to update the BIOS it seems.

an automatic way of doing so :
1: download and burn as ISO image (same as with ubuntu CD) : http://www.lesgrosbarbares.info/flashbiosacer_v1_43.iso
2: boot to this CD
3: should autoflash your bios...
4 reboot, all good
