Hi @sethumol,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I’m sorry you’re going through this; I understand the concern and don’t worry I’ll help you with this.

To better understand the issue, could you please provide a few more details?

1. What is your exact HP laptop model?
2. When did the battery problem start suddenly or gradually?
3. Does the laptop shut down even when it shows some percentage remaining?
4. Have you recently installed any updates or replaced the charger/battery?

 Troubleshooting Steps to Try

1. Perform a Battery Calibration

Sometimes the battery meter becomes inaccurate.

1. Charge your laptop to 100%.
2. Keep it plugged in for 1 more hour.
3. Unplug it and use it until it shuts down by itself.
4. Charge it uninterrupted back to 100%.

This helps Windows relearn the true battery capacity.

2. Run HP Hardware Diagnostics

HP has a built-in tool that can check battery health.

1. Turn off the laptop.
2. Press Esc repeatedly → choose F2 System Diagnostics.
3. Run the Battery Test.

Let me know what result it shows (Normal, Weak, Replace, etc.).

3. Update BIOS and Battery Drivers

Sometimes false percentages are caused by outdated firmware.

• Open Device Manager → Batteries
  Right-click each item → Update Driver
• Visit HP Support → enter your serial number → check for a BIOS update or Battery driver.

4. Try a Battery Reset

Some HP models have a reset option in BIOS.

1. Restart PC
2. Press F10 to enter BIOS
3. Look for Battery or Power Reset, if available.

5. Check Charger and Ports

A faulty or incompatible charger can cause rapid drain and incorrect charging behavior.

• Are you using the original HP charger?
• Does the charging port feel loose or intermittent?

I hope this helps.
