@kingpin300800, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

It sounds like you're experiencing a frustrating issue with your HP Notebook 15-dy1036nr where the battery drains even when the laptop is powered off. This can be caused by several factors, and I’m here to help you troubleshoot the problem. Here’s a breakdown of possible causes and their fixes:

🔋 Possible Causes and Fixes:

1. Modern Standby (Fast Startup / Connected Standby)

Windows 10/11 sometimes doesn’t fully shut down the system; instead, it enters a low-power state called Modern Standby or Fast Startup, which can drain the battery.

👉 Fix:

• Open Control Panel > Power Options > Choose what the power buttons do.
• Click “Change settings that are currently unavailable.”
• Uncheck “Turn on fast startup (recommended)”.
• Save changes, then shut down and see if the issue persists.

2. Battery Health or Faulty Battery

If the battery has degraded or is faulty, it might lose charge quickly even when powered off.

👉 Check Battery Health:

• Press Windows + X > Windows Terminal (Admin).
• Type: powercfg /batteryreport and hit Enter.
• Go to C:\Users\YourUsername\battery-report.html and open the file.
• Look for Design Capacity vs Full Charge Capacity — a large difference indicates a worn-out battery.

3. BIOS Settings or Issues

Sometimes, certain BIOS settings (like USB charging while off, Wake on LAN, etc.) can drain power.

👉 Fix:

• Enter BIOS by pressing Esc or F10 repeatedly during boot.
• Look for settings like:
  • "USB Charging in powered off state" → Disable.
  • "Wake on LAN/WLAN" → Disable.
• Save and exit.

Also, ensure your BIOS is up-to-date:

• Visit the HP Support page for your model and install the latest BIOS version (look under the BIOS section).

4. Malware or Background Activity

If the laptop isn’t fully shutting down and is instead entering sleep or hibernate mode, malware or background applications may keep it semi-active.

👉 Fix:

• Open Task Manager > Startup tab — disable unnecessary apps.
• Run Windows Security > Full Scan, or use Malwarebytes to check for malware.

5. Battery Drivers or System Power Bugs

A corrupted ACPI driver (battery controller) could cause this issue.

👉 Fix:

• Press Windows + X > Device Manager.
• Expand Batteries.
• Right-click both Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery, then click Uninstall device.
• Restart your laptop. Windows will automatically reinstall them.

🧪 Test This:

After performing the above steps:

• Shut down the laptop completely (hold Shift and click Shutdown).
• Leave it off for a few hours.
• Power it up and check the battery level.

If the battery still drains significantly, the issue could likely be due to battery degradation or a motherboard-related power leak.

I hope this helps. 

Take care and have a good day.

Thank you for response, @kingpin300800. 
Thanks for running through those steps — if the battery still won’t charge to 100%, that strongly points to either a battery health issue or firmware/software limiting the charge. Let’s dig a bit deeper:

🔍 Let’s cover all the bases:

✅ 1. Check Battery Wear Level

Have you checked the battery-report.html yet? Here's what to look for:

• Open it and find:
  • Design Capacity
  • Full Charge Capacity
  • Cycle Count

If Full Charge Capacity is significantly lower than Design Capacity (like under 80%), your battery is physically degraded and might need replacement.

You can send me the report or just those two numbers if you’d like me to evaluate it.

✅ 2. Battery Charge Limit in BIOS

Some HP BIOS versions include a setting like Battery Care Function or Battery Health Manager, which caps charge to 80% to extend lifespan.

➤ How to check:

1. Reboot and press F10 repeatedly to enter BIOS.
2. Look under Advanced > Power Management Options or System Configuration.
3. If you see a setting like:
   • "Battery Care Function" or
   • "Maximum Battery Charge Limit"

✅ 3. BIOS Update

Even if you already checked this, double-check that you're running the latest BIOS:

• Go to HP Software & Drivers for 15-dy1036nr.
• Install the latest BIOS update under the BIOS section.

Sometimes charging bugs are fixed in firmware updates.

✅ 4. Calibrate the Battery

If it’s just stuck showing the wrong charge level (e.g., it stops at 93% or 98%), recalibrating may help.

➤ Steps:

1. Charge the laptop to as high as it will go.
2. Use the laptop normally until it shuts down on its own (don’t plug in).
3. Let it sit powered off for 1 hour.
4. Plug it back in and charge to 100% without interruption.
5. Restart the system.

This can help Windows "relearn" the correct battery level.

✅ 5. Hardware Diagnostics

Run HP’s built-in diagnostics:

• Reboot and press F2 or Esc > F2.
• Choose Battery Test under System Diagnostics.
• If it says "Replace Battery" or fails the test, that’s your answer.
   

I hope this helps!
