Where to find C940 14 motherboard to replace?

Hi,

More information is needed to be able to help you.

You would need to know the specifications of the motherboard that you have e.g. CPU i5 or i7, amount of ram etc to know which one to get.

There are 24 different motherboards available for the laptop. Click on Select Commodity > System boards (24) to find the part numbers.

If you can’t work out which part number is applicable to your particular model then try typing the laptop’s serial number in the search box on the page in the link above to see if that helps. The serial number is usually found on the information label under the laptop. Scroll down to Using the Printed Product Label > IdeaPad and Lenovo notebooks (including Miix tablets and Yoga)

Once you have the correct part number, search online using the part number only to find suppliers of the part.

Here’s the hardware maintenance manual for the laptop.

Go to the bottom of p.39 to view the necessary pre-requisite steps and then the procedure to remove the systemboard. Sometimes the part number is shown on the board if you wish to verify that you’re ordering the correct part.
