Hello! I started receiving "Dell Power Manager" message months ago: "The power adapter attached to your system is not recognized. Attach a supported power adapter with with at least 45 watts." I kept ignoring the warning because this is the only adapter I have. However, a few weeks ago, I received error messages that forced me to shut down and reboot many times. I hold the ctrl + alt + delete or the power button button until it closes. I also received an email alert that there are two internet surveillance recently. Sorry, I haven't taken a screen shot of the errors about computer storage or something. Please let me know what to do or provide you with first. I may not have a moment until tonight again. Thank you!

Hi, Lisa.

Apparently, this is a common issue with Dell laptops. This Dell Knowledge Base article goes into detail: How to Troubleshoot AC Adapter Issues on a Dell Laptop.

Basically, one of the most likely causes of this problem is a damaged or loose center pin on the DC connector of the power adapter. To check if this is the case, you can try the following steps:

• Unplug the power adapter from the laptop and the wall outlet.
• Inspect the DC connector for any signs of damage, such as cracks, bends, or breaks.
• Try to wiggle the center pin gently and see if it moves or feels loose.

In the event the center pin is damaged or loose, you will need to replace your power adapter with a new one. You will need to make sure that the power adapter matches the specifications of your laptop model and has the same or higher wattage rating. You can find the wattage rating on the label of the power adapter or on the bottom of your laptop.

Another possibility is a damaged or loose DC-in connector on the laptop (the port where you plug in the power adapter to your laptop). To check if this is the case, you can try the following steps:

• Unplug the power adapter from the laptop and the wall outlet.
• Inspect the DC-in connector on the laptop for any signs of damage, such as cracks, bends, or breaks.
• Try to wiggle the connector gently and see if it moves or feels loose.

If you find that the DC-in connector is damaged or loose, you will need to repair or replace the DC-in connector on your laptop. Unfortunately, this is a more complicated and expensive process and will require professional help from Dell technical support or a local computer technician for more information and options.

It is also possible it is a BIOS issue.  Instructions for updating the BIOS are in the referenced Dell article.

As to the "internet surveillance alerts", a security check is likely in order.  See the log posting instructions  here.

Corrine,

I apologize for the delay! I was working this weekend! I followed your instructions about the adapter and I didn't receive an error message this morning. Also, I looked last night and this morning for the advanced settings in Microsoft Edge and "Customize and control Google Chrome" in Google Chrome but I'm unable to find them. I've attached a screen shot of my settings from Microsoft Edge. Please advise my next steps. Thank you!

Since you didn't receive an error message this morning, it could very well be that unplugging and repluging the power adapter from the laptop and the wall outlet fixed that issue. 

The Microsoft Edge settings are fine.  As to Google Chrome, I don't use it but the instructions here may be helpful: Access Chrome Settings.
