A user reports that a corporate laptop charges normally up to exactly 60% capacity, at which point charging stops completely despite remaining plugged into the factory AC adapter. The laptop operates normally on AC power alone, but the user requires full battery capacity for traveling. Which of the following actions should the technician perform to address and diagnose this issue? (Select TWO.)
- Inspect the vendor battery management utility or UEFI settings to see if a charge threshold or battery health preservation mode is enabled.Answer
- Run hardware diagnostics in the system UEFI or OS environment to check the health status, full charge capacity, and cycle count of the battery.Answer
- CPerform multiple deep discharge cycles down to 0% to eliminate memory effect and recalibrate the battery charge controller.
- DMove the charging cable to any standard USB Type-C port on the laptop without verifying Power Delivery (PD) support.
- EImmediately replace the motherboard power IC before inspecting software or firmware power management settings.
Answer
The technician should inspect the vendor battery management utility or UEFI settings for enabled charge limits and run system hardware diagnostics to evaluate battery health and cycle count.
Checking the vendor battery management utility or UEFI settings directly addresses software charge caps, which frequently limit charge levels to 60% for battery preservation. Additionally, running built-in battery diagnostics provides empirical health and cycle metrics needed to confirm physical battery condition.
