| The charging indicator does not turn on | Power adapter, wall outlet, charging connector, or DC-in circuit problem | Test a known-working outlet, inspect the cable for cuts, and check whether the connector feels loose or unusually hot | No indicator usually means the computer is not receiving stable input power | Try a compatible adapter with the correct voltage and wattage. If there is still no response, professional inspection may be required | Repair Check |
| The computer works only when connected to the adapter | Battery failure, deeply discharged cells, or a disconnected internal battery cable | Shut down the computer, disconnect external power, and observe whether it starts or remains powered by the battery | A system that immediately loses power often has a battery that can no longer hold usable charge | Review battery health information. Replacement is generally appropriate if the battery is detected but has very low capacity | Replacement Likely |
| Battery percentage remains at 0% or 1% | Severely degraded cells, charging-control fault, or an inaccurate battery gauge | Restart the computer, check the operating system battery report, and compare the design capacity with the full-charge capacity | A full-charge capacity below approximately 80% of design capacity indicates noticeable aging; much lower capacity indicates advanced wear | Replace the battery when capacity is very low or runtime is substantially reduced. Seek repair if a new battery shows the same behavior | Replacement Likely |
| Charging stops at about 80% | Battery-protection or conservation setting limiting the maximum charge | Review the computer's battery-care or charge-limit settings | A deliberate charge limit can reduce long-term lithium-ion battery stress and is not necessarily a fault | Disable the limit only when a full charge is needed. Re-enable it for regular plugged-in use if desired | Normal Setting |
| Battery charges very slowly | Low-power adapter, heavy system load, high temperature, damaged cable, or battery aging | Close demanding applications, improve ventilation, and verify that the adapter meets the computer's required power rating | Charging may slow or pause when power consumption is close to the adapter's available output | Use the correct adapter, cool the computer, and replace the battery if slow charging is accompanied by poor runtime or sudden shutdowns | Check First |
| Charging works only when the cable is held at a certain angle | Worn cable plug, damaged charging socket, or loose internal connection | Carefully observe whether slight movement interrupts the charging indicator; do not force or repeatedly bend the connector | Intermittent charging points to a physical connection problem rather than ordinary battery wear | Stop stressing the connector and arrange professional repair. Continued use can worsen port or board damage | Professional Repair |
| The battery is swollen, the case is lifting, or the touchpad is raised | Internal lithium-ion cell failure and gas buildup | Visually inspect the case without pressing, puncturing, or attempting to flatten the battery | Swelling is a safety hazard and is not corrected by software resets or calibration | Turn off the computer, disconnect external power if safe, avoid using or charging it, and obtain qualified battery service promptly | Urgent Safety Issue |
| The battery is not detected by the operating system | Disconnected battery, failed battery-management electronics, firmware issue, or motherboard fault | Check battery information in system settings and firmware diagnostics, if available | No detected battery makes software-only troubleshooting less likely to succeed | After a safe restart, seek professional diagnosis if the battery remains absent. Do not open the case if the battery is swollen | Professional Repair |
| Battery runtime has fallen sharply after normal use | Normal lithium-ion aging, repeated heat exposure, or high cycle count | Compare current full-charge capacity with the original design capacity and note unexpected shutdowns | Reduced capacity is expected over time; rapid drops, shutdowns, or extreme heat suggest replacement is warranted | Back up important data and replace the battery with a compatible, safety-certified part | Replacement Recommended |
| The computer shuts down immediately after unplugging | Battery cannot deliver sufficient current, battery connection fault, or power-management failure | Check whether the battery percentage changes normally and whether the system reports a battery health warning | Immediate shutdown indicates that the battery is not supplying usable power | Replace the battery if it is detected and degraded. Request board-level diagnosis if a replacement battery behaves identically | Replacement or Repair |
| Battery becomes unusually hot during charging | Blocked ventilation, high workload, damaged adapter, charging-circuit fault, or failing cells | Stop intensive tasks and check for excessive heat, odor, smoke, or physical swelling | Mild warmth can be normal, but excessive heat, odor, or deformation is not normal | Disconnect power if safe, stop using the computer, and seek professional service for any safety warning signs | Urgent Safety Issue |
| Charging resumes after a complete shutdown and restart | Temporary power-management, firmware, or operating-system communication error | Perform a normal shutdown, wait briefly, reconnect the compatible adapter, and start the computer again | A one-time recovery suggests a temporary control issue rather than immediate hardware failure | Install stable system and firmware updates, monitor the battery, and seek service if the issue repeatedly returns | Monitor |
| Battery health is poor but charging and runtime remain stable | Gradual chemical aging without an immediate charging-circuit fault | Review the battery report and track runtime over several charge cycles | A health warning alone does not always mean immediate failure, but capacity will continue to decline | Plan a replacement before runtime becomes inconvenient or unexpected shutdowns begin | Plan Replacement |
| Several compatible adapters fail to charge the computer | Damaged charging port, internal power board, motherboard circuit, or battery-management system | Confirm that each adapter has the correct specifications and test whether the charging indicator responds | Failure with multiple suitable adapters makes an internal hardware problem more likely | Stop replacing adapters at random and arrange professional diagnostics | Professional Repair |
