Step-by-Step Repair
- Step 1 of 61
Check the charger and cable
Use the original charger and cable if possible. Try a different cable and outlet. Damaged or third-party chargers often can't deliver enough power.

Clean the charging contacts
Inspect and clean all charging contacts, ports, or terminals. Use a dry toothbrush or cotton swab with isopropyl alcohol for metal contacts. Remove lint from ports with a toothpick.

Check battery health
Most devices have a battery health indicator in the settings. If the battery health is below 80%, the battery is degraded and may need replacement.

Calibrate the battery
Let the device run until it completely dies. Then charge it to 100% without interruption. This recalibrates the battery meter and can fix inaccurate readings.

Reduce power consumption
Lower screen brightness, disable unused features (Bluetooth, WiFi, GPS), and close background apps. Check which apps are using the most battery in your settings.

Consider battery replacement
If the battery is old (2+ years of heavy use) and calibration doesn't help, replacement is likely needed. Many batteries can be replaced for $20-$60, which is much cheaper than a new device.

If That Didn't Work
- Try a hard reset: unplug the charger, remove the battery if possible, hold the power button for 30 seconds.
- Boot into Safe Mode to check if the issue is software-related.
- Check if an external monitor works to rule out screen vs. GPU issues.
When to Call a Professional
If the motherboard or GPU is the issue, repair costs can run $200-$500. At that point, compare with the cost of a refurbished or new laptop. If your laptop is over 4-5 years old, replacement is usually the better investment.
