In order to troubleshoot a laptop not charging after a software update, follow these steps:

1. Check the power adapter to ensure it is firmly connected to the laptop and to the power outlet.


2. Make sure the power outlet can provide your laptop with the power it requires.


3. Ensure that other electrical equipment in the same outlet is not drawing power away from your laptop.


4. If the problem persists, restart the computer following the correct procedures.


5. Check device settings to make sure the laptop is configured to use the AC adapter power.
