Overheating in tosh sat pro 4600

Nov 10, 2007

- Here's a link that will take you the disassembly of Toshibas. Didn't find the 4600 on it, but maybe you can find one that is close. Besides cleaning the fan, you may want to try cleaning the area around the processor chip. I doubt that replacing the fan will buy anything.
Hopefully this additional information will be of assistance to you.

- I sent you something but I don't think that it went through. This is a test to see if this will go through.

- OK, that went through.

I don't think that this is a hardware problem. I fixed a similar problem on a laptop that was caused by some mal-ware driving the processor so hard that it kept overheating. The problem seemed to come and go.
When you run this program, bring your pc up in safe mode. This will allow the program to access the hidden partitions on the disk. Some of the viruses and malware will hide in the hidden partitions and standard anti-virus/malware programs will never find them. This program is free and good enough that I reccomend using this instead of Norton or any of the other name brand programs.
Here is the link:

After you install this, it will ask you for a registration code. Just hit cancel and you will be able to run the free edition.

I think that this may be the fix for your problem.

- And a good morning to you!
Just was checking in to see how you're coming along on this.

- Good morning, again.
Well, sorry to hear that you are still having the problem. Looks like I was wrong on the virus thing! ;o(
But, it sounds like you've done about everything that you can do, software wise.
This is one of the joys of trying to diagnose a problem over the internet. You can't get your hands on the unit to actually see what's going on.
So, that only leaves 3 things, that I can think of. First, the fan. Secondly, the processor and third, the motherboard. Of the 3 I would agree with you that the fan is most likely cause.
Since you've learned a lot about disassembly of this unit, that's surely something you can handle.
