Hello,
I've been looking all over for a solution to this problem and didn't really know where to turn so I decided to start here. Here we go:
About a week and a half ago, in my Ubuntu 12.04 boot, I noticed my computer was burning up and I can't remember whether it shut off itself or I did because I noticed the fan wasn't running. Anyways, I boot into Windows 7 to see if the fan would turn on but it didn't and it went into thermal shutdown.
I took out the fan and tried powering it with a power supply but it was broken.
This is the fan I got:
http://www.ebay.com/itm/New-HP-Comp...2z-G62t-G62m-G62x-G42t-CPU-Fan-/330945432154?
I'm not sure if it's after market or the manufacturer replacement fan. It's probably after market.
Fast forward to Tuesday when my fan comes in; I install it with ease and I boot into Ubuntu. The fan works, but after about 5-7 minutes of use the screen flickers a couple times and shuts down. No error messages; it were as if you ripped the battery out of the laptop. I restart to see if it happens again and it does but this time approximately 15-30 seconds after booting up. (This is the common trend: when I start it cold, it gets 5-7 min, subsequent restarts get 15-30 sec. This leads me to believe that Ubuntu thinks it's overheating but isn't getting correct temperature data from BIOS.)
I boot into Windows 7 to see if this happens there. It doesn't. I can use Windows for hours with out it shutting down. The strange thing is, it doesn't even feel warm. I know what it's like for my laptop to burn up. I've run it to the point where touching the metal ports could burn skin and it still would take some to put it into thermal shutdown. So basically I can guarantee the computer isn't actually overheating. I also tried updating BIOS.
I then took my computer apart again to see if I screwed up and couldn't find anything except for a wire going to the screen being pinched by the hinge (which I thought was the problem but it's now appearing to be a lot less likely because the screen wouldn't cut out like clockwork). Still the same thing.
I tried being in root in tty while the shut down occurs. The only message I got was just the wireless adapters shutting off before it crashed. I'll attach the picture I took.
The reason why I've decided to post here instead an Ubuntu forum is because the problem persists when I've tried running the trial on my live flash drive for Ubuntu 12.04, 13.10, and Fedora 19. So I think this is a Linux issue in general.
My guesses:
-Linux doesn't know how to handle the drivers for the fan. (This is unlikely because I thought it was handled by BIOS.)
-Linux isn't reading the temperature data from BIOS correctly. (This is unlikely because the temperature has nothing to do with the fan so it shouldn't have changed. As far as I know the fan has three wires, Power, Ground, and Tachometer.)
-My computer is actually overheating and Linux is smart enough to actually shut down and Windows isn't. (This is unlikely because it doesn't feel warm and Windows has gone into thermal shutdown when my system has gotten too hot before.)
-I screwed something up putting it back together each time. (This is always a possibility.)
-This is a display/video problem. Maybe my GPU was damaged last thermal shutdown. (This is unlikely because it works fine in Windows.)
I know I labeled everything as "unlikely", but if I thought something was likely, I wouldn't be posting.
My computer:
-Compaq Presario CQ62-220US
-Known battery issue (I occasionally get messages on start up in Windows saying I should replace it. It has a terrible battery life.)
If you guys have any insight/suggestions/comments/jokes, I would be happy to hear them.
Thanks in Advance,
