How to get my HP Pavilion to hold a charge.

Perform an HP power reset first, then run the built-in UEFI Battery Test; a Failed result means the battery needs service or replacement, while Calibrate means the battery gauge should be recalibrated.

1. Perform a power reset

1. Shut down the Pavilion.
2. Disconnect the AC adapter and all USB devices.
3. If the battery is designed to be removed without opening the laptop, remove it. Do not open the case solely for this step.
4. Hold the Power button for about 15 seconds.
5. Reinstall the removable battery, if applicable.
6. Connect the correct AC adapter directly to the laptop and turn it on.

HP recommends a power reset as the first action for charging and battery problems.^1^

2. Run HP’s battery hardware test

This test runs outside Windows, helping distinguish a Windows display/driver issue from a battery failure:

1. Turn off the laptop.
2. Turn it on and immediately tap Esc repeatedly.
3. Press F2 to open HP PC Hardware Diagnostics UEFI.
4. Select Component Tests → Power → Battery.
5. Run the battery test and follow the matching result:^2^
   • Passed: Continue with the adapter and Windows checks below.
   • Calibrate: Run the calibration offered by the diagnostic tool. HP notes that this may take 12–14 hours.
   • Failed: Record the Failure ID and contact HP or a qualified repair shop for battery replacement.
   • No battery/Unknown: The battery connection or charging circuitry needs physical inspection.

Do not attempt calibration if the battery is swollen, unusually hot, leaking, or lifting the case or trackpad. Shut down and stop using the laptop until it is serviced.

3. Verify the charger is correct for this exact Pavilion

Trying another HP charger and a universal charger does not rule out an adapter problem. They may have the wrong voltage, wattage, connector, or—if charging through USB-C—the wrong USB Power Delivery capability.

Check that:

• The adapter is specified for the laptop’s exact Pavilion model and meets its required voltage and wattage.
• It is connected directly to the designated charging port, not through a dock or hub.
• The cable, connector tip, and laptop port have no bending, looseness, damage, or debris.
• If it charges through USB-C, both charger and cable support the power level required by the laptop.

Microsoft confirms that an incompatible or underpowered charger can leave a PC charging slowly or discharging while plugged in.^3^ HP provides corresponding adapter and port checks.^4^

4. Check battery wear in Windows

Right-click Start, select Terminal (Admin), and run:

powercfg /batteryreport /output "$env:USERPROFILE\Desktop\battery-report.html"

Open battery-report.html from the desktop and compare:

• Design Capacity — original capacity
• Full Charge Capacity — current usable capacity

The command creates an HTML report of the battery’s usage and capacity characteristics.^5^ If Full Charge Capacity is much lower than Design Capacity, that supports battery wear or failure—but the HP UEFI result should guide replacement.

5. Only if the HP battery test passes

Reset Windows’ battery device:

1. Right-click Start → Device Manager.
2. Expand Batteries.
3. Right-click each listed battery device and select Uninstall device.
4. Select Start → Power → Restart. Windows should reinstall the devices automatically.
5. Reconnect the correct adapter and check whether the percentage rises.

This is a secondary Windows-side measure when hardware diagnostics pass.^6^

The orange/white light pattern alone cannot identify the fault across every Pavilion model. If the battery test passes but a confirmed exact-model adapter still leaves it at 12%, the charging port, internal battery connection, or motherboard charging circuit requires inspection.
