What type of thermal interface is used in lenovo g40-45

Hi all,


Recently I've noticed that my G40-45 keeps overheating even when I do not use it. I think, I should replace the thermal interface inside, but I am not sure what type of it my laptop has.


I need to be 100% sure about the type of the TI before starting to disassemble my laptop, you know, in order to not screw everything up even more. Smiley Tongue


Thanx in advance.

A good cleaning out of the air vents (canned air) to remove dust from the heatsink and fans could be a good way to go as well.

Before you try to replace the TI - it is a very good idea to read up on just how it is put together. If you click on Support link at the top of this site, you will be able to enter your system information and pull up related information including Hardware Maintenance Manual, User Guide and more.

Good luck.

Hi juliar,


Welcome to the Community Forums.


In addition, if reapplication of thermal paste and cleaning of the fan is not enough and you need parts, then you can get the heatsink and fan using your serial number or MTM here on the parts lookup page.


Guideline for ordering parts here, hardware manual, and service module for reference.
