How to Fix 'Cannot Use USB Power Delivery' on Laptops: A Step-by-Step Guide

Have you ever plugged your laptop into a charger and been met with the frustrating notice, "Cannot Use USB Power Delivery"? If so, you're definitely not alone. USB Power Delivery (USB PD) is a fast-charging technology used by many modern laptops, smartphones, and other devices. It's supposed to make charging quicker and more efficient, but when it doesn't work right, it can leave you scrambling for solutions, especially when your device is running low on power.

Before stressing out, take a deep breath. The issue might not be as grave as it seems and can often be resolved with some simple troubleshooting. Here’s how to fix the “Cannot Use USB Power Delivery” issue on laptops in simple English.

Understand the Issue

First things first: USB Power Delivery is a universal charging standard. That means it's designed to work across a range of devices, not just your laptop. The "Cannot Use USB Power Delivery" issue generally means your laptop isn’t accepting the charge being sent to it, either due to a problem with the charger, the cable, the laptop's port, or an internal software issue.

Check Your Charger and Cable

1. Inspect the Charger

Ensure you're using the correct charger for your device. Not all chargers are made equal, and using one that's not meant for your laptop can cause charging issues.

2. Examine the Cable

Sometimes, the problem lies not with the charger but with the cable. Look for any visible signs of wear or damage. If possible, try using a different USB-C cable (make sure it supports USB PD) to see if that resolves the issue.

Inspect Your Laptop’s Charging Port

A dirty or damaged charging port might also be the culprit. Gently inspect your laptop's charging port and clean out any dust or debris using a can of compressed air. Be careful not to insert anything into the port, as this could cause damage.

Update Your Drivers and Firmware

Outdated software can sometimes interfere with USB Power Delivery. Here's how to make sure everything is up to date:

1. Update Your Laptop's BIOS/Firmware

Check your laptop manufacturer's website for any BIOS or firmware updates specifically for your model. Updating your BIOS or firmware can sometimes resolve charging issues.

2. Update USB Drivers

The same goes for USB drivers. Ensure that they are up to date by checking the device manager on your laptop. Look for any yellow exclamation marks next to USB controllers, which indicate a problem. Right-click and select "Update driver" to ensure they're current.

Try a Different Power Source or Outlet

It might sound simple, but sometimes the issue could be with the power source or outlet you're using. Try plugging your charger into a different outlet or, if you're using a power strip, try plugging directly into the wall to see if that makes a difference.

Power Cycle Your Laptop

A full power cycle can sometimes reset any temporary issues preventing charging. Completely shut down your laptop, unplug it from any power source, and remove the battery if possible. Press and hold the power button for about 15 seconds to drain any residual power. Then, reinsert the battery (if applicable), plug the laptop back in, and try charging again.

Reset the System Management Controller (SMC)

On macOS laptops, resetting the System Management Controller (SMC) can help fix various hardware issues, including charging problems. The steps to do this vary depending on whether you have a Mac with a removable battery, a non-removable battery, or a T2 chip. You can find detailed instructions on Apple’s support website.

Consult the Professionals

If you've tried all these steps and your laptop still refuses to accept USB Power Delivery, it might be time to consult with a professional. There could be an underlying hardware issue that needs expert attention.

Remember, while it’s frustrating when technology doesn’t work the way it’s supposed to, there’s often a solution to be found. By methodically working through potential issues, you can usually find the fix. Whether it’s a simple case of using the wrong charger or cable, or you need to update your laptop’s software, you’re now equipped with the knowledge to tackle the "Cannot Use USB Power Delivery" issue head-on. Keep this guide handy, and happy charging!
