    Hello friend.

     

    In this case when a shutdown without warning and is on constantly heated, it is because the fan is dirty or is not functioning at the appropriate speed to dissipate heat, or may not be working.

     

    Try cleaning the fan and keep your laptop in a cool environment, for time alone Use it plugged in without battery, to see if that way is also turned off.

     

    You know as an energy drain done?

     

    To do this you must disconnect the battery charger and press 6 times the button on / off.

     

    After you do a battery calibration, stop discharging the battery to 3% and when discharged, turn off the laptop, you connect the battery, charger and place it to charge for 4 hours, and will complete its 100% load properly.

     

    After that, use your laptop as normal and checks off.

     

    I hope you find it useful the information and help you solve the problem.

     

    I you comment if you worked.

    in my experiance, it was because your gel (pasta) between cpu and fan sink or vga and fan sink become dry-out.

    you can try after clean the fan, cleaning the gel and place new one.
