Hi dear community,

 

I am using Windows 10 64-bit OS with a Toshiba Satellite C855-26U laptop.

 

Here is some properties of the computer

 

Bios: 6.20

Processor: Intel® Core™ i5-3230M CPU @ 2.60GHz (4 CPUs), ~2.6GHz

Memory: 8192MB RAM

 

Now let me explain my problem,

This computer is like 3 years old, and about a year ago, I wanted to open the laptop and clean the fan because there was some heating problem. Not too bad, but I thought it was gonna get worse so I wanted to clean it.(Did not use gloves) After I finished, I reassembled the laptop and started using, however, there was some problem. While gaming, computer was rebooting after some time of game time. This was unpredictable because it can happen after 15 minutes or 4 hours of game play. I made some tests to find out the problem, nothing professional of course, just like checking the heat, using different adapter so on. This was a year ago so I cannot remember all but I also remember doing some cpu stress tests, the computer passed them fine. But I can apply them again if necessary. Now allow me to specify the characteristics of the problem in a list because I find them confusing.

 

  • It happened once while not gaming.
  • We switched computers with my father because he didn't play any games. He says he did not encountered any issue in a year with this computer.
  • The problem existed before upgrading to Windows10
  • Taking off the charger and playing a game while on battery power prevents this problem.
  • I tried using another adapter, the problem persisted.
  • When the problem occurs, The computer reboots, but sometimes it does not reboot, the screen goes black, the computer keeps running for a while(all functions disabled). And then shuts down without rebooting. This happens in a arbitary order, cannot determine which one will happen.

Now let me share some of my opinions on the problem,

I don't thinks it's the charger because I tried another one and the problem started just after I disassembled the laptop to clean the fan. My best guess why removing the charger prevents the problem is because it reduces the computer performance so it prevents some kind of overloading(not sure). So my guess about the problem is that the static electricity on my hand may disrupted a circuit part somewhere on the computer while cleaning the fan. I wanted to know if you had any idea about the problem and which part may be corrupted, or is there any methods to find more about this problem. I wait your respond.

 

Thanks in advance.

Unfortunately, there's not a lot you can do about a laptop as most of the parts aren't replaceable.

Still, you can start with these free diagnostics:  http://www.carrona.org/hwdiag.html

Let us know the results and we'll move on from there.

I made the GPU stress test, my graphic card reached 60 C max. And I used the CPU burner, my cpu temperature stabilizes at 84 C while doing that test. I do not know what to make of these however. ( Computer didn't cause any problem during the tests)

 

CPU heat is 50-55 C idle.

 

Note: CPU heat also reached 80-82 C with the charger removed. So CPU heat seems unlikely the cause of the problem given that removing the charger prevents the problem. Also I thought CPU heat causes computer shutdowns rather than reboots, at least it was like that in my previous toshiba computer.

I would investigate your CPU cooling solution.

With a laptop, the first thing to do is to blow out all the vents with canned air (DON"T USE an air compressor or a vacuum as they can physically damage the components).

Beyond that, I'd post over in the Internal Hardware forums for some advice from the experts there:    http://www.bleepingcomputer.com/forums/f/7/internal-hardware/

 

 

I'm uncertain of what controls the reboot vs shutdown in the Toshiba BIOS, but suspect that there are actions defined in the BIOS for these events.
