I have used my laptop for 1.5 year, which is Dell Inspiron 1320.
Recently, I just installed Ubuntu 11.04 Desktop to my laptop. However, I'm facing very strange problem that I did not face before.
- If the laptop is booted to Ubuntu, it will automatically shutdown after a while ** randomly**. ( I believe the shutdown is not triggered by events)
- If the laptop is booted to Windows 7, there is no such problem. Windows 7 runs very stable and good.
- If the laptop is booted to BIOS setup menu, the problem is as same as that boot to Ubuntu.
I also tried turning on the laptop without battery but with AC power directly. But the problem still exists. So the battery problem has been eliminated.
I suspected dust blocked my laptop's fan/cooler/head detector... So I cleaned every parts in my laptop yesterday. However the problem still exists.
Anyone has any idea about solving the problem?

I highly suspect that Ubuntu changed my "Overheat protection" settings in BIOS and Ubuntu did not set it correctly. Why I suspect that? Because I tried that:
- Start Ubuntu and log in to Ubuntu.
- Shutdown the laptop in Ubuntu with normal way
- Start the laptop and enter BIOS setting menu
- Auto shutdown after a while (maybe 1~2 min)
- Start Windows 7 and log in to Windows 7
- Shutdown the laptop in Windows 7 with normal way
- Start the laptop
- During laptop starting, there is a message "System updated" (something like that. I am not sure the exact word, but I can sure the meaning. It just showed up for maybe 0.2 sec)
- Enter BIOS setting menu
- The computer does not have problem!!!
