Checking The Ac Power Adapter - Lenovo YOGA C630-13Q50 Hardware Maintenance Manual

Checking the ac power adapter

You are here because the computer fails only when the ac power adapter is used.
• If the power problem occurs only when the docking station or the port replicator is used, replace the
docking station or the port replicator.
• If the system status indicator does not blink three times when an ac power source is connected, check the
power cord of the ac power adapter for correct continuity and installation.
• If the computer does not charge during operation, go to "Checking the battery and operational charging"
on page 22.
Note: Noise from the ac power adapter does not always indicate a defect.
Checking the USB-C type ac power adapter
To check the USB-C type ac power adapter, do the following:
1. Connect the computer to a power outlet and turn on the computer.
2. Start Lenovo Companion program, and then click Hardware Settings ➙ Power. The ac power adapter
information is displayed.
Ensure that you use the USB-C type ac power adapter that is shipped with the computer to provide enough
power to the computer. Otherwise, a message will be displayed, prompting you that the computer will not be
charged or will be charged slowly.
