Introduction
The connection card is responsible for allowing the computer to read and communicate with external hardware. If your card is having issues, the ports on the right side of your computer will not connect to external hardware.
Before following this guide, try connecting other cables and devices with the same port. If other cables or devices are able to connect, you may be having an issue with a cable or device that needs to be replaced.
Before you proceed, make sure to power the computer all the way down and disconnect the charging cable. Replacing the connection card will require the removal of the battery and fan.

- Remove the back cover from the laptop
- DO NOT BEND OR PUNCTURE THE BATTERY: Puncturing the battery can result in injury since the battery can catch fire or explode when exposed directly to oxygen
