Laptop Not Charging — Causes and Replacement Charger
A laptop that will not charge is usually down to the charger, the cable, the charging port or the battery. This guide takes the checks in order, so you can tell which it is and, if it is the charger, choose the right replacement.
In short: Check the wall socket, the charger and its cable, and the laptop’s charging port first. Then try a known-good charger with the same connector, voltage and wattage: if the laptop charges, replace the charger; if it does not, the battery, port or laptop needs a service check. A replacement must match the connector and voltage exactly, with wattage equal to or higher than the original.

Start with the quick checks
1. Check the power source
Try a different wall socket, and plug the charger in directly rather than through an extension board, dock or hub. Confirm the charger’s indicator light, if it has one, comes on.
2. Look at the charger and cable
Check the cable along its length and at both ends for cuts, kinks or bent pins, and note whether the adapter body gets unusually hot. If anything looks damaged, stop using the charger.
3. Look at the charging port
Check the laptop’s port for lint, dust or a bent pin, and check the plug fits snugly. A loose connection can charge on and off as the cable moves.
4. Restart the laptop
Shut the laptop down, unplug the charger, wait a minute, then plug it back in and start it. A restart clears many temporary charging faults, and it is worth checking the battery-care settings too.
Common reasons a laptop stops charging
The charger has failed
Adapters and cables wear out, most often at the cable ends. A dead indicator light, a flickering light or an adapter that has gone cold are signs to test another charger.
The charger does not match
A charger with the wrong connector or voltage will not work, and one with too little wattage can charge slowly or not at all, especially while you work. Match all three: connector, voltage and wattage.
The port or cable is worn
A charging port with a bent pin or a loose socket, or a USB-C cable that does not carry power, will stop charging even when the charger is fine.
The battery is worn
A battery that has aged can stop holding a charge or make the laptop run only on mains power. This needs a battery check, not a new charger.
Is it the charger? A simple test
Borrow or use a charger you know works with the same connector, voltage and wattage as your laptop’s original. If the laptop charges with it, the original charger or its cable is the fault and should be replaced. If it still does not charge, the fault is more likely the port, the battery or the laptop itself, and a service check is the next step.
Stop using any charger that is damaged, overheating or smells burnt, and do not use a charger with the wrong voltage as a test.
Choosing a replacement charger
A replacement has to match three things: the connector, the voltage and enough wattage. Read them off the rating label on your original charger, or from your laptop’s specifications, and choose a wattage equal to or higher than the original. Our laptop chargers and power adapters guide explains each step and compares the models.
Then pick your brand: Apple, ASUS, Acer, Dell, HP, Lenovo, Microsoft Surface. Or browse every model on the laptop chargers and adapters page.
When it is not the charger
If a matching charger does not fix it, the problem is the battery, the charging port or the laptop’s own power circuit. Contact the laptop maker’s service centre for those; a new charger will not solve them.

Frequently asked questions
Why does my laptop say "plugged in, not charging"?
Common causes are a charger with lower wattage than the laptop needs, a worn battery, or a battery-care setting that caps the charge level. Try a charger that matches your original connector and voltage with equal or higher wattage, and check the battery settings; if the message stays, the battery or port needs a service check.
Can a wrong charger damage my laptop?
A charger with the wrong voltage or a connector that does not fit can stop the laptop charging and may damage it. Match the connector and voltage printed on the original charger exactly, and never force a plug that does not fit.
How do I tell whether the charger or the battery is at fault?
Try a charger you know works with the same connector, voltage and wattage. If the laptop charges, the original charger was the problem. If it still does not, the fault is more likely the battery, the charging port or the laptop itself.
My USB-C laptop is not charging from a USB-C charger. Why?
The laptop must charge over USB-C, the charger must supply enough wattage, and the cable must carry power. A 65W USB-C charger suits many thin laptops, while gaming and workstation laptops often need 150W or more.
