Dell Chromebook 3100 2-in-1 Input Output Board Replacement

简介

If your Dell Chromebook 3100 2-in-1 fails to turn on, please refer to our troubleshooting guide.

If your laptop is plugged into an outlet with a working adapter, but the device will neither charge nor power on, this is a sign that the charging port is damaged and needs to be replaced. For this configuration, the charging port is on the left when the bottom cover is facing up. Another way to identify the charging port is to look for a Type C port with a lightning bolt symbol on top.

To complete this guide, it is not necessary to remove the battery; instead, the battery connecter can be disconnected to isolate power to the system during the process.

NOTE: The input and output board depends on the configuration ordered. Not all system configurations come with the input and output board.
