Windows 11 home, battery system has worked normally until just recently. Suddenly about a week ago the battery icon disappeaed, computer charging indicator light on the side of the computer turned off, and battery charging turned off and remained off until low battery shutdown, then starts to charge again. Charges until full, with the compter indicator light on, but no battery iccon in the task bar. When full the the battery icon appears again. As soon as the battery falls below 100%, the battery econ disappes again. the computer charging light turns off, and charging is disabled until low power shutoff. Then the cycle repeats.Have tried several fixes. When I unintall battery drivers and restart, the battery icon appears and and shows a charge percendage, but that remains frozen, and the battery is probably discharging because the charge indicator light on the side of the computer is off. All of this is very strange and behond my ability.

    Hi!

    Battery-related issues are generally caused by the battery itself, as its charge and charging process are managed by the device rather than by Windows.

    To better diagnose this issue, please generate a battery report—as instructed by the AI ​​Answer—and send the file to me for analysis.

    1. Type "Command Prompt" in the Search Bar > Right-click on the app > Select ''Run as administrator''.
    powercfg.exe /batteryreport /output C:\battery-report.html
    1. A report will be generated in This computer > Local Disk C named battery-report. Upload this file to OneDrive:

    The next step is to generate a Windows battery report and install the laptop manufacturer’s firmware updates, because reinstalling the battery driver has already failed and charging that resumes only after shutdown requires separating faulty battery telemetry from hardware or firmware charging control.

    1. Generate and inspect the battery report

    1. Right-click Start, select Terminal (Admin), and approve the prompt.
    2. Run:
    mkdir C:\Reports -ErrorAction SilentlyContinue
powercfg.exe /batteryreport /output C:\Reports\battery-report.html
start C:\Reports\battery-report.html

    The report includes the installed battery, recent power states, charge-capacity history, and battery usage. Microsoft documents it as a way to identify battery-life inconsistencies.^1^

    Check these sections:

    • Installed batteries: Compare Full charge capacity with Design capacity. A substantially reduced full-charge capacity indicates battery wear.
    • Recent usage and Battery usage: Look for missing readings, abrupt percentage changes, or entries that jump directly from 100% to shutdown.
    • Battery capacity history: Check whether the reported capacity changed sharply around the time the problem began.

    If the report contains no usable battery data, remains stuck at one percentage, or shows abrupt impossible transitions, Windows is not receiving reliable battery status from the laptop’s power subsystem. Windows depends on the platform to report charging/discharging state and immediately notify it when that state changes.^2^

    Go to:

    Start → Settings → Windows Update → Advanced options → Optional updates

    Install available firmware and relevant hardware-driver updates, then restart. Optional drivers are not installed automatically, so they must be selected manually.^3^

    If none appear, use the laptop manufacturer’s official support site for the exact model and install its latest:

    • BIOS/UEFI firmware
    • chipset or platform driver
    • power-management or system-control software

    Follow the manufacturer’s BIOS instructions exactly and keep the AC adapter connected. Do not interrupt a firmware update.

    Also check the manufacturer’s battery utility or BIOS for a charging threshold or battery-protection setting. Windows Smart charging normally limits charging to a lower level and displays a heart on the battery icon; it does not normally hide the icon and wait for a low-battery shutdown before charging again. Smart-charging implementation and controls vary by manufacturer.^4^

    3. Check the external power path

    If the laptop charges through USB-C:

    1. Connect the original charger and cable directly to the laptop—not through a dock or hub.
    2. Use the designated charging-capable USB-C port.
    3. Inspect the port for debris or a loose connection.
    4. If available, test with another manufacturer-approved charger of the required power rating.

    An incompatible or underpowered USB-C charger, incorrect port, inadequate cable, debris, or a dock can prevent charging.^5^

    When service is appropriate

    If the indicator still switches off below 100% and charging resumes only after the laptop shuts down—even after OEM firmware updates and testing the correct charger—the laptop needs physical diagnosis. Likely areas for a technician to test include the battery pack, battery telemetry/controller, charging port, adapter, and motherboard charging circuit.

    Do not deliberately repeat full discharge-to-shutdown cycles; the machine is already doing this, and another calibration cycle would add little diagnostic value. Back up important files while the laptop can still run. If the battery is swollen, the case is separating, or the laptop becomes unusually hot, stop using and charging it and arrange service immediately.
