Introdução
If the USB-C port or the USB-A port on the left side of your Asus Chromebook CX1500CN is not working, it may be due to a malfunctioning daughterboard.
The daughterboard is not a vital part of the computer, but it must be replaced if a functioning I/O port is missing. You will need a #1 Phillips screwdriver and, optionally, an iFixit opening tool.
