Laptop Plugged In but Not Charging: What to Check

01Quick answer

When a laptop is plugged in but not charging, the usual suspects are the charger or cable, a loose or dirty charging port, a USB-C charger that isn’t powerful enough, or a battery setting that deliberately pauses charging to protect the battery. Check the charger and connection first, then look at your battery settings and health. This guide is for owners of Windows laptops and MacBooks whose battery won’t fill up, charges slowly or drains while plugged in.

02Before you start

• Read the battery icon. On Windows, hover over the battery icon in the taskbar; on a Mac, click the battery icon in the menu bar. Messages such as “plugged in, not charging” or “charging on hold” point to different causes.
• Use the original charger or one the laptop maker lists as compatible. Chargers for phones and tablets often can’t power a laptop.
• Don’t force the connector into the port or bend it to make it work.

03Why this happens

Usually simple to fix:

• The wall outlet, extension strip or charger isn’t supplying power.
• The cable is damaged or not pushed fully into the laptop or the charger brick.
• Lint or dust in the charging port stops the connector seating properly.
• A USB-C charger supplies less power than the laptop needs, so it charges very slowly or not at all under load.
• A battery-care feature is holding the charge at a lower level on purpose. Many Windows laptops and Macs have such features; they’re normal.
• The laptop is working hard (gaming, video editing) and using power as fast as the charger supplies it.

Needs the manufacturer or a repair service:

• The battery has worn out with age and use, so it holds much less charge than when new.
• The charging port is loose or damaged.
• The battery is swollen, very hot or leaking.

04Check the charger and connection

1. Try a different wall outlet directly, without an extension strip.
2. Check every connection. Many chargers have two parts: the cable from the wall to the brick, and the cable from the brick to the laptop. Push both in firmly.
3. Look at the cable and brick for fraying, kinks, scorch marks or a damaged plug. Don’t use a damaged charger.
4. Look into the charging port with a light. If you see lint, switch the laptop off and gently remove it with a wooden toothpick or a puff of air. Don’t use metal objects.

   Is it charging now? If yes, keep the port clean. If not, continue.

5. For USB-C, try another USB-C port on the laptop, and check your charger’s power rating against what the laptop maker recommends. Microsoft notes that a lower-powered charger may charge slowly or not keep up.

05Check battery settings and health

On Windows

1. Look for battery-care settings. Many laptop makers include an app that limits charging to protect the battery, and Windows itself has power and battery settings under Settings, then System, then Power & battery (or Power & sleep on Windows 10). If charging stops at a set level, this is probably why.
2. Restart the laptop. A restart can clear a charging glitch.
3. Create a battery report to see the battery’s design capacity compared with its current full charge capacity. Search for Command Prompt, open it and type powercfg /batteryreport, then press Enter. It saves an HTML report and shows where. Open it in a browser and compare the two capacity figures.

   What you should see: if the full charge capacity is far below the design capacity, the battery has worn and may need replacement by the manufacturer or a repair service.

On a Mac

1. Open the battery settings in System Settings, then Battery. If Optimized Battery Charging is on, your Mac may hold the charge below full until it expects you to need it.
2. Check battery health in the same area, where macOS shows the condition and may recommend service.
3. Check the cycle count. Apple’s support page explains how to see your Mac laptop’s cycle count and what it means.

06Common mistakes to avoid

• Using an unofficial or bargain charger that isn’t rated for your laptop.
• Bending the charging cable tightly around the brick for storage, which damages it over time.
• Assuming the battery is broken when a battery-care feature is simply pausing the charge.
• Leaving a hot laptop charging on a bed or sofa, where it can’t cool. Our overheating guide explains why that matters.

07If it still doesn’t work

If the laptop won’t charge with a known-good original charger, a clean port and a restart, or if the battery report or macOS shows a battery in poor condition, contact the manufacturer through its official support website or a qualified repair service. Built-in batteries should be replaced by professionals.

If the laptop doesn’t start at all, see our guide to a laptop that won’t turn on. If it charges but runs slowly on battery, our slow computer guide covers power and performance settings.

08The short version

Use the original charger in a working wall outlet, check the cables and port, and confirm a USB-C charger has enough power. Then check for battery-care settings that pause charging and look at battery health. Worn, swollen or damaged batteries need professional replacement.

09FAQ

Why does my laptop stop charging before it’s full?

Many laptops and Macs include battery-care features that hold the charge below full to reduce wear. Check your laptop maker’s app or your battery settings. You can usually turn the feature off if you need a full charge.

Can I use a phone charger to charge my laptop?

Some USB-C laptops accept phone chargers, but they usually supply far less power than the laptop needs, so charging is very slow or stops when the laptop is in use. Use the charger supplied with the laptop or one its maker lists as compatible.

Is it bad to keep my laptop plugged in all the time?

Modern laptops manage charging automatically, and many have battery-care features to reduce wear when plugged in for long periods. Microsoft’s and Apple’s battery guidance explains the settings for each system.

How do I know if my laptop battery needs replacing?

Signs include much shorter battery life than when new, a battery report or macOS battery status showing poor health, or the laptop shutting off suddenly. A swollen battery needs attention straight away.
