You may be facing a hardware problem if:
- The laptop heats up even when idle
- Battery percentage drops suddenly (for example 60% → 20%)
- The laptop shuts down even when battery shows power left
- Battery health is below 70%
- The battery drains extremely fast after charging
In such cases, software fixes may not be very effective.
It is recommended to get the battery and motherboard checked by a technician.
When Should You Replace Your Laptop Battery?
You should consider replacing your laptop battery if:
- The battery is swollen or bulging
- The laptop turns off suddenly without warning
- The battery backup is less than 1 hour
- The battery cycle count has reached its limit
- Battery calibration does not improve performance
If these symptoms appear, replacing the battery is the best and safest solution instead of forcing software fixes.
