The HP EliteBook 840 G11 is a 14 inch business laptop that charges over USB-C, and a laptop that will not charge has a power adapter or cable problem, a battery protection state or a managed setting from an employer. Start with the supply: use the HP USB-C adapter of the right wattage, plugged into a wall outlet, with the cable that came with it.
The checks in more detail
Business laptops often refuse to charge from a weak charger or a phone charger, or charge so slowly that the battery falls while in use. Look for the charging light and the battery icon. Try both USB-C ports, since a dock on one port can affect charging, and test without the dock. Inspect the ports and the connector for lint and damage. Perform a hard reset by unplugging everything, holding the power button for fifteen seconds and then connecting the charger alone.
HP business laptops include a battery management setting, in HP Battery Health Manager or the BIOS, that holds the charge at about eighty percent to extend the battery's life, and a laptop that stops at that level is working as set; change it in the HP app if you want a full charge, unless your IT department controls it. Update the BIOS and the embedded controller through HP Support Assistant or HP Image Assistant, and reinstall the battery driver in Device Manager.
HP PC Hardware Diagnostics UEFI, run from F2 at start-up, tests the battery and reports its health. A battery near the end of its life holds little charge and may refuse to charge fully. If the laptop is managed by an employer, contact the helpdesk, which may need to replace the battery under a service plan. Keep the serial number and the diagnostics ID for the call. Stop using the laptop if the case bulges or the base is hot.
