Keyboard and Battery issue with HP ENVY x360 Convertible 15

[AM1092]

Hello All, I own HP ENVY x360 Convertible 15 purchased in Dec 2019 and now I am suddenly facing below 2 issues:

1. The laptop no more turns ON or remains ON without constant power plugged in. How can I know whether the battery is dead or is it a driver issue? If driver issue, how can I troubleshoot and find it for my self? If battery, where can I find a replacement?

2. Only certain section of the keyboard is acting weird like keys around letter P. Sometimes they work, sometimes they won't. Its crazy! Doesn't look like there is a hardware problem.

@AM1092, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Based on your situation with the HP ENVY x360 Convertible 15 (Dec 2019) running Windows 11, here’s how to diagnose and address both issues:

Battery Issue – Laptop only works when plugged in

Determine if it's a dead battery or driver issue:

Step 1: Basic Battery Health Check

• Plug in the charger and power on the laptop.
• Run HP Hardware Diagnostics (built-in):

1. Press Esc repeatedly after turning it on, then press F2 for diagnostics.
2. Choose Component Tests > Power > Battery.
3. Run the Battery Check and note the result (e.g., “Replace”, “Calibrate”, “Passed”).

Step 2: Use HP Support Assistant

• If Windows boots, open HP Support Assistant and go to Battery Health Check under "Battery" section.
• It will report battery condition (Good / Weak / Replace).

Step 3: Check with Windows

• Open Command Prompt and run: 
  powercfg /batteryreport
• This generates a battery report in C:\Users\<YourUsername>\battery-report.html.
• Look for Design Capacity vs Full Charge Capacity and recent usage stats.

If it's a driver or firmware issue:

• Open Device Manager > Batteries and uninstall Microsoft ACPI-Compliant Control Method Battery.
• Restart the laptop; Windows will reinstall it automatically.
• Also check for BIOS/firmware updates on HP Support Site.

If battery is faulty (likely, after 4–5 years):

Replacement battery part number (check inside battery diagnostics).

Purchase options:

HP Parts Store: click here

Keyboard Issue – Some keys (like around 'P') not working properly

Troubleshooting steps:

Step 1: Rule out software issues

Boot into Safe Mode:

• Press Shift while clicking Restart.
• Go to Troubleshoot > Advanced Options > Startup Settings > Restart > F4 (Safe Mode).
• Test the keys in Notepad. If they misbehave here too, likely hardware issue.

Step 2: Use On-Screen Keyboard

• Press Win + Ctrl + O to bring it up.
• Compare input behavior to determine if it's hardware-related.

Step 3: Test with HP Hardware Diagnostics (keyboard test)

• Same as battery check: Esc > F2 > Component Tests > Input Devices > Keyboard.
• Follow on-screen instructions to press keys — it will show which keys are registered.

I hope this helps. 

Take care and have a good day.
