Why Is My Laptop Not Charging?
Common Laptop Charging and Power Problems — and What to Do
Is your laptop not charging, charging only at certain angles, showing “plugged in” but not gaining battery power, or refusing to charge at all?
Charging problems can be caused by the charger, charging port, battery, power-management circuitry, or the laptop itself. A damaged charging port can also become worse if the plug is forced or used while loose.
The first step is to identify whether the problem is with the charger, cable, charging port, battery, or laptop hardware.
What Does a Laptop Charging Problem Actually Mean?
The laptop does not charge at all
There is no charging light or charging indication when the adapter is connected.
Possible causes include a faulty charger, cable, charging port, battery or internal charging circuit.
The laptop says “plugged in” but the battery does not increase
Windows or macOS detects the power adapter, but the battery percentage stays the same or continues to fall.
The battery may be worn out, the charger may not provide enough power, or there may be a charging-system problem.
Charging works only when the plug is held at a certain angle
The laptop charges intermittently or stops charging when the cable moves.
A damaged cable, loose connector or worn charging port may be involved.
The charging port feels loose or damaged
The plug does not fit firmly, the port moves, or the connector appears physically damaged.
Continued use can cause further damage to the port or motherboard and should be checked.
The laptop charges very slowly
The battery takes much longer than usual to charge, or charging slows significantly during use.
The charger may be underpowered or faulty, the cable may be unsuitable, or the battery may be worn.
The laptop works on the charger but shuts down when unplugged
The laptop runs normally while connected to power but turns off quickly when the charger is removed.
The battery may be severely degraded, disconnected or faulty.
The charger gets hot or the charging connection is unstable
The adapter or connector becomes unusually hot, or charging repeatedly starts and stops.
A faulty charger, damaged cable, poor connection or hardware fault may be responsible.
Common Causes of Laptop Charging Problems
- Faulty AC adapter — The charger may have failed or may no longer provide the required output.
- Damaged charging cable — A broken or internally damaged cable can cause intermittent or slow charging.
- Wrong or underpowered charger — A charger with insufficient wattage may not charge the laptop properly, especially while it is in use.
- Damaged charging port — The socket may be loose, worn, physically damaged or disconnected internally.
- Worn-out battery — An ageing battery may have reduced capacity or may no longer accept a normal charge.
- Dust or debris in the port — Contamination can prevent the connector from making reliable contact.
- Battery or power-management problem — Internal charging circuitry can fail even when the charger appears normal.
- Software or firmware issue — Less commonly, operating-system or firmware problems can affect charging behaviour or battery reporting.
What to Do When Your Laptop Does Not Charge?
On Windows
For Windows laptops, including Windows 10 and Windows 11.
Try these checks before arranging a repair:
1. Check the charger and power connection- Make sure the charger is firmly connected to both the wall outlet and laptop.
- Check the cable and adapter for cuts, bent connectors, unusual heat or visible damage.
- Look at the battery icon and charging status in Windows.
- If it says plugged in but the percentage does not increase, continue testing rather than assuming the port is faulty.
- Where possible, test with a charger that has the correct voltage, connector and sufficient wattage for the laptop.
- Do not use an unsuitable charger simply because the plug fits.
- Check for looseness, visible damage or debris.
- Do not force the plug or repeatedly move it to make charging work.
On a Mac
For MacBook models using recent versions of macOS.
Try these checks before arranging a repair:
1. Check the USB-C or MagSafe connection- Make sure the charging cable and connector are seated properly.
- Try another compatible charging port if the Mac has more than one.
- Check the battery status in the menu bar or System Settings.
- If the Mac detects power but the battery percentage does not increase, continue testing.
- Use a charger and cable suitable for the Mac model and its required power.
- A USB-C cable that fits physically may not necessarily support the required charging power.
- Check for debris or physical damage.
- Do not force a damaged connector or continue using a port that is loose or unusually hot.
When Should You Stop Troubleshooting?
- The charging port is loose, broken or physically damaged
- The charger, cable or connector becomes unusually hot
- You smell burning or see signs of melting or scorching
- The laptop charges only when the plug is held at a particular angle
- The battery is swollen or the laptop case is lifting
- The laptop shuts down unexpectedly when the charger is removed
- A known-compatible charger does not solve the problem

Don't Keep Using a Damaged Charging Port
If the charging port is loose, damaged, sparking, unusually hot, or only works when the plug is moved into a particular position, continued use can make the damage worse.
Do not force the connector or repeatedly bend the cable to maintain contact. If the battery is swollen, the case is lifting, or you notice burning smells or excessive heat, stop using the laptop and have it inspected.
