What to do if your laptop's battery stops charging, as explained by our Helproom Expert.

QUESTION I'm unable to charge up my three-year-old Acer laptop, but I'm not sure whether the fault is with the charger or the battery. Should I buy a new charger and, if so, where's a good place to get a replacement? Geek84

HELPROOM ANSWER If the charger has an indicator light, check whether this comes on when it's plugged into the mains. If it doesn't, you may need to replace the fuse in its plug. Before you do, check the power outlet works by plugging in a different device.

If your charger is enabling you to turn on and use the laptop, but it isn't charging the battery, then the battery is at fault. Contact the laptop manufacturer for its official component if either needs replacing. Third-party replacements are often available, but ensure the power rating matches that of your original charger.
