Acer Aspire E 15 E5-551-T9MG

Don't know if it actually overheats because it doesn't get very hot on the outside.
But according to the thermistors the CPU cores are at 145
°C.
HWMonitor info:



It started doing this suddenly the evening of 27/5 2020.
Me and a friend have cleaned it. We opened it, used compressed air to clean from dust, he also changed the cooling paste to a new and better one.
To see the video of me going through all (which pictures above are from), and also to see the task manager, go to https://www.reddit.com/r/JonTV/comments/gwgl3n/oops/
It is not overclocked, if it is then it is just a few MHz which my brother did long long ago. But I think he reset it though.
Yes, I have tried to run it without battery. Still the same.
I am currently having it in the basement which is about 19
°C so I don't think it's a big problem with the air around it.

Any idea? Is it the thermistors showing wrong temperature, or is it actually that hot? How can I fix it?

  • Did this problem occur after any windows update? What happens when you restore windows to a date before the 27th?

    Latest windows update was 13/5
  • I think there may be some defective sensor. Also, what is the version of the bios?

    V1.15

  • OK! Access the bios and then press f9 to restore and then press f10. Then, turn off the notebook, disconnect the battery and press the power button for 60 seconds to verify that the power reset resets the temperature parameters.

    After the BIOS reset, if it's still overheating, start looking at system resources. See if anything is using a high level of CPU. Lower the priority if it is, and see if the temp starts to drop. I'm not sure if the E5s are packing fans any more or if they've switched to a passive design, but two years ago my E5 did have a very quiet exhaust fan, so assuming that's still true... check for it. Make sure the exhaust is blowing air out... fans are common points of failure in laptops, and it's really easy to miss that one if it goes on the blitz because it's so unobtrusive and quiet when it is working.

    Doesn't seem like it. Now it forces to do a Disk repair and then shuts off like it has done from overheat the last 2 1/2 weeks

    well the fan is working but how to check it is working the right way?

    Look at my video I uploaded to https://www.reddit.com/r/JonTV/comments/gwgl3n/oops/ where I have task manager in the right half, check it

    Can't get on system now, because after I did
    OK! Access the bios and then press f9 to restore and then press f10. Then, turn off the notebook, disconnect the battery and press the power button for 60 seconds to verify that the power reset resets the temperature parameters.
    It doesn't let me cancel the disk repair which it did before, so it takes too long to get anywhere before it shuts off

    well yeah i get there, but what then? Also it still shuts off btw so it's very limited time (~3-5 mins)
  • I still think that some sensor is reporting the wrong temperature. Do it:
    a) disconnect the lition battery and the rtc battery from the CMOS
    b) then, press the power button for 30 seconds to eliminate static energy.

    Battery seems kinda stuck :astonished:

  • Do not remove the rtc battery as it is soldered on the motherboard! What happens when you update the bios to the latest version?

    How do I update? Also it's the latest version already because I bought the laptop after the newest BIOS version was released
  • Can you check the version of the bios? I still think the thermal sensor may be in trouble and showing a wrong temperature reading.

    I still think there may be a problem with the temperature sensor. However, try to perform the power reset:
    a) turn off the notebook, disconnect the power adapter and the lition battery;
    b) press the power button for 60 seconds;
    c) check if the problem occurs with the lithium battery disconnected.
