Short answer: Check the adapter and plug first. If it runs on the adapter and dies when unplugged, the battery is usually at fault. If charging never starts, adapter, port and battery are checked together. Do not use a swollen battery.
Quick split
- Dies as soon as you unplug: The battery may be worn out or not recognised.
- Still not charging with the adapter in: Adapter, cable, charge port or board-side.
- Percentage stuck or wrong: Calibration sometimes helps; often the battery needs replacing.
- Case or trackpad raised: The battery may be swollen — I recommend a safe replacement.
Safe checks at home
- Use the correct wattage and voltage.
- Seat the cable firmly and try another socket.
- Check battery health in Windows if you can.
- If the battery is swollen, shut down and do not force it.
When do you need service?
If the adapter is right and the connection is firm, but it still will not charge or the battery is swollen, port / battery / board diagnosis is needed.
FAQ
Should I fit a cheap battery?
Low-quality cells swell and die early. The correct, known-quality part is safer.
Must the adapter be original?
Wattage and the tip must match. A “compatible” wrong supply can cause trouble.
Charging trouble in Fethiye? On-site diagnosis. I do not replace parts until battery, adapter or port is clear.
