  • Thank you for your message.


    How long have you been having this issue? What is the operating system installed?


    Does the computer restart or shutdown when it heats up?


    Observe if this happens when the AC adapter is connected.


    Is the area on the upper left corner of the keyboard heating up?


    Update the bios from this link http://dell.to/2u5l5kh (update this even if you have the latest version) 


    Run a hardware diagnostic by following this link http://bit.ly/2fJuGXB & check if there is any error listed.

    I think near three month, windows 8.1 profi (genuine) ,

    No restart or shutdown, because I always control cooling fan using third party software now,

    these issues happened always. But AC adapter or buttery has some kind of issues, updated my previous

    post with images. please check it,

    no, Touch pad and Right bottom (near touch pad)(Motherboard chip), I updated my previous

    post with images. please check it

    BIOS was updated, now cooling fan is working, but still heating (touch pad)

    hardware diagnostic test was run, result is normal.

    I already emailed with my service tag, I waiting for reply.

  • Thank you for the update.


    Please disconnect the AC adapter remove the battery. Press and hold down the power button for 30 seconds to release the static.


    Connect only the AC adapter & use the computer for some time (without the battery) and check if the system is still heating.


    With the battery indicator light lit up in amber, seems like the battery will require a replacement.


    Please edit or delete the image which has the service tag in bios, this is for security reason as your system details are open to public.
