HP ProBook Windows 10下“已接通电源，未充电”故障求助

Hey there, sorry to hear your HP ProBook is giving you this frustrating charging issue—let’s walk through some more fixes that might get your battery back to charging normally, since the steps you’ve already tried didn’t work:

• Inspect your AC adapter and connections thoroughly
  Even if it looks fine, check for tiny frays in the cable, bent pins in the charger plug or laptop’s power port, or dust buildup in the port. Sometimes a subtle damage or blockage is the culprit. If you can borrow a genuine HP AC adapter (third-party chargers often cause compatibility problems), test with that to rule out a faulty charger.

• Run the HP Battery Check tool
  HP laptops have a built-in utility that can diagnose battery or charging issues:

  1. Open the Start menu and search for HP Support Assistant
  2. Launch it, navigate to the Troubleshooting tab
  3. Select Battery Check and follow the on-screen prompts. It’ll tell you if the battery is failing, if there’s a software glitch, or if hardware needs attention.

• Reset your power plan to default settings
  Corrupted power management settings can sometimes block charging:

  1. Open Control Panel > Power Options
  2. Click Change plan settings for your currently active power plan
  3. Choose Restore default settings for this plan, then restart your laptop and check charging again.

• Update your laptop’s BIOS/UEFI
  Outdated firmware can cause hardware communication issues that lead to charging problems. Here’s how to do it safely:

  1. Search for your specific HP ProBook model + "BIOS update" to find the latest firmware from HP’s support resources
  2. Download the update file (make sure your laptop is plugged in during this process—never shut it down mid-update!)
  3. Run the file and follow the instructions to install, then restart your laptop.

• Test for battery hardware failure
  If all software fixes fail, it might be a faulty battery:

  • If your battery is removable, take it out, hold the power button for 30 seconds to discharge residual power, reinsert the battery, and plug in the charger.
  • For non-removable batteries, you’ll likely need to take the laptop to an HP service center to get the battery tested or replaced.
