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.

 

I have asked this question before and suggested to ask to this topic instead. Here is the other topic if you need some information about what I did already.

Playing with battery = lower clock speeds on CPU and graphic card, so I expect laptop is overheating. Try to put some cooling on bottom of laptop.

There is a cooling device on bottom of the laptop, however I never encountered any situation that device delaying this problem or preventing it. Also as I said in the other post the CPU and GPU heats of the computer while plugged and unplugged are almost the same. And usually the computer heat in toshiba laptops can be felt with hand by touching the laptop from outside, if it is overheated it usually hurts your hand when you touch it. It does not happen in this situation. Thank you for your reply btw.

Then another guess is laptops power components next to power connector. That's somewhat hard to see without opening laptop. That shouldn't be problem as laptop should use battery instead, but faulty chip may not report fast enough and so switch to battery power fails.

 

That laptop also seem to have external graphics which often causes problems on laptops. Nvidia solder issues is quite a legend.

What type of issues usually result with rebooting ? (Like adapter not supplying enough energy) The research I made generally reveals that adapter is the problem most cases. So I am going to try and find a new one. However this also feels like a dead end to me.

Unless new adapter helps, then something is probably broken. But quite hard to tell what.
