How to Fix Power Surge Error on Windows?

by Soft2share.com
The “power surge on the USB port” is one of the rare errors Windows users encounter. According to the error message itself, an unknown USB device needs more power than the port can supply. Considering the error message alone, anyone can assume that one of their peripherals is acting up, but it is only partly true your operating system can also be the culprit. In this article, we’ll look at why this error occurs, how to fix it, and, if all else fails, what alternatives you have at your disposal.

There are many reasons for a power surge on the USB port error in windows 7 or windows 10. One of the reasons for this is if the USB draws a current that is much higher than it’s threshold value. USBs are normally designed with maximum limits and if the limit is exceeded, it may lead to system errors. Try connecting it to another system to fix where the problem is coming from. If you are sure that the problem is not from the USB device but lies with the port or the system try one of these methods to fix the error.

What is a Power Surge on a USB Port?

When you get an error notification about a power surge on your USB ports, the port you’re trying to use can’t relay enough power to the device. Generally, anything plugged into a port reporting a power surge won’t work.

This happens because there’s only so much power your computer can give USB devices; when that amount is exceeded, it simply can’t run the USB devices you’re trying to connect. The power required can’t be supplied, and the USB device won’t be able to run without the power it needs.

What Does the “Power Surge on the USB Port” Error Mean?

There is a limit to the amount of power or current a USB port can deliver. All USB 2.0 ports can supply a current of 500mA, which translates to a maximum power output of 2.5W. For USB 3.0 and 3.1, the values are 900mA and 4.5W. USB devices are designed to function within these limits. However, if you buy cheap headphones on sale for an extremely low price and think you’ve found a treasure, its in-built circuit may not honor the limitation. Due to this, it may start drawing more power than the USB port can handle.

If this happens, the Windows operating system detects a potential power surge at one of your USB ports and starts alarming you about it. Do not panic; your port won’t spark, and you won’t see smoke coming out of it since the operating system will automatically disable it. Even so, there is the possibility that damage may already have happened before the operating system even realizes what’s happening.
