How to check if your laptop is actually charging
Check your laptop’s reported charging state, compare the battery level over time, and find out whether the adapter, settings, or battery needs attention.
Your laptop is plugged in, but the battery percentage is not going up. Or the power icon says it is connected, and you are not sure whether the battery is charging. A connected adapter does not always mean the battery is gaining charge.
Use the Battery Meter to check the battery’s reported charging state and level. Compare the level again after a few minutes, then use the results to decide whether to check the charger, a setting, or the battery itself.
Check whether the laptop is charging
- Open the Battery Meter on the laptop you are checking. The tool only appears on devices whose browser reports battery information, so it may not be available in every browser or setup.
- Plug the laptop into its charger and make sure the cable is firmly connected at the wall, adapter, and laptop. If it charges over USB-C, use a port that supports charging.
- Look at the battery level and the reported charging state in Battery Meter. Note the percentage and whether the state indicates that power is connected and charging.
- Leave the laptop plugged in for 10 to 15 minutes. Keep your use light and avoid launching a game or other demanding task while you wait.
- Check the level and charging state again. A higher percentage is clear evidence that the battery gained charge. If it is unchanged or lower, use the results below to narrow down why.
The percentage may update in small steps rather than continuously. A short wait can be inconclusive, especially if the battery is nearly full or the laptop is using a lot of power.
What the result means
The charging state indicates charging and the percentage rises
The adapter is supplying power and the battery is gaining charge. If the laptop still shows a warning or shuts down unexpectedly, the issue may be with the battery’s ability to hold charge rather than its ability to charge. A browser reading cannot measure battery health precisely.
The laptop is connected to power, but the percentage stays the same
The adapter may be powering the laptop without adding charge to the battery. This can happen when a charge limit is enabled, the battery is very full, the laptop is too warm, or the computer is using power as quickly as the adapter supplies it. Repeat the check with the laptop cool and idle.
The level falls while the laptop is plugged in
The laptop may be drawing more power than the charger can provide, or it may not be receiving power reliably. A lower-wattage adapter, an unsuitable USB-C port, a damaged cable, or a heavy workload can cause this. Check the charger and cable before assuming the battery is faulty.
The browser does not show battery information
Some browsers or laptop configurations do not report battery data to web pages. This does not prove that the battery is broken. Check the battery indicator in Windows or macOS instead, or try another browser if your device allows it.
How to fix it
- Check the outlet and connections. Try a different wall outlet and reseat the cable at both ends. Look for a loose connector, bent plug, frayed cable, or a charging light that switches on and off as you move the cable.
- Use a compatible charger and port. If possible, try the charger supplied with the laptop or one that meets the laptop maker’s power requirements. With USB-C charging, not every USB-C port or cable supports the same power level.
- Reduce the laptop’s power use. Close demanding apps, pause large downloads, and let the laptop cool on a hard surface. Then check the battery level again after 10 to 15 minutes.
- Check the operating system’s power settings. In Windows 11, open Settings › System › Power & battery and review the battery and power options. On macOS, open System Settings › Battery and review the available battery settings. Some laptop makers also offer a charge limit or battery conservation setting in their own utility.
- Restart the laptop. A restart can clear a temporary reporting or power-management problem. After it starts, reconnect the charger and check the reported state and level again.
- Check for a persistent charger or battery problem. If a compatible charger works only at certain angles, or the laptop repeatedly stops charging, contact the laptop maker or a repair shop. Do not open the laptop to inspect its battery unless the manufacturer’s instructions say it is user-replaceable.
When the charger or battery may be faulty
If the battery level falls with the laptop idle and connected to a known-good, compatible charger, the charging port, adapter, cable, or internal charging hardware may need attention. Test one known-good charger and cable at a time if you can, so you can tell which part changes the result.
If the laptop only charges when the connector is held at an angle, stop bending or forcing it. The port or cable may be damaged. If the battery case or laptop looks swollen, stop using and charging the laptop, keep it away from heat, and arrange professional service. Do not press on or puncture a swollen battery.
What Battery Meter can and cannot tell you
Battery Meter reads the battery information that the browser receives from the laptop, including charge level, charging state, estimated time left, and drain rate. The operating system supplies these readings, and they can be rounded or delayed. Comparing the level over time is more useful than relying on a single instant.
The tool cannot verify the charger’s exact wattage, inspect the charging port, or confirm how much capacity the battery has lost with age. Treat its result as a way to check whether charge is changing, then use the laptop’s settings or a compatible charger to investigate further.
