Why Your HP Laptop Only Runs on Charger – Complete Troubleshooting Guide

When an HP laptop powers on only when the charger is plugged in, it usually points to a problem with the battery, power settings, or hardware connections. This issue is more common than people think, and the good news is—most of the time, you can fix it at home with a few simple steps. For deeper hardware checks, the HP Authorised Service Center in Patna can handle the rest.

1. Common Reasons Why HP Laptop Works Only on Charger

(a) Battery Not Detected or Not Charging

Sometimes the battery loses its capacity or disconnects internally, causing the laptop to shut down once the charger is removed.

(b) Corrupted Battery Drivers

Faulty drivers can stop the system from communicating with the battery.

(c) Loose or Faulty Battery Connection

If the battery connector is loose inside, the laptop may not read the battery.

(d) Power Settings & BIOS Glitches

Outdated BIOS or incorrect power settings may prevent the battery from functioning properly.

(e) Hardware Fault (Battery or Motherboard)

A dead battery or faulty charging circuit can also cause this issue. In such cases, the HP Authorised Service Center in Patna is the safest place to diagnose the motherboard.

2. Step-by-Step Solutions to Fix the Issue

Follow these steps one by one. In most cases, the problem gets solved before you reach the last step.

✔ Step 1: Check Battery Health

Shut down the laptop.
Remove the battery (if removable).
Clean the connectors gently.

✔ Step 2: Perform a Hard Reset
