Won't power on, battery issues

[tfelmore]

So... My laptop works completely fine if it is plugged in. If it dies however, I am unable to turn it back on with the power button. I have actually discovered that the only way to get the laptop back on is by removing the battery and plugging it in - it will then power on (automatically, not via the power button) and I am able to re-insert the battery (while keeping it plugged in.) It is super inconvenient having to completely take the laptop apart and remove the battery any time that it dies. I keep it plugged in to avoid the issue but I am a travel nurse so sometimes it dies on long trips... and then I have to do the whole tedious process to get it back on. And yes, I have already replaced the battery but I am unable to properly calibrate it since I can't turn the computer off / on to do so. Any help would be awesome!

Hi @tfelmore, Welcome to HP Support Community. 

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

It sounds like your HP Pavilion x360 - m3-u103dx has a power-related issue, likely caused by a faulty battery circuit, a motherboard issue, or a BIOS-related glitch. Since you've already replaced the battery, let's go through some troubleshooting steps to pinpoint and hopefully fix the issue.

1. Reset the Embedded Controller (EC)

The Embedded Controller manages power functions. Resetting it may resolve the issue.

• Step 1: Unplug the laptop and remove the battery.
• Step 2: Press and hold the power button for 30 seconds.
• Step 3: Reinsert the battery and plug the laptop back in.
• Step 4: Try turning it on normally.

If this doesn’t work, continue with the other steps.
 

Check Battery & Power Button Behavior

Since your laptop powers on automatically when you plug it in without the battery, your power button or battery circuit might be faulty. Try:

• Pressing the power button multiple times in rapid succession to clear any debris or stuck behavior.
• Testing power button functionality by booting with the battery in and the charger unplugged.

If the power button does nothing until you remove the battery and plug in the charger, the issue could be with the power management circuit or BIOS.
 

Update or Reset BIOS

Your laptop might be stuck in a low-power state after shutting down.

• Download the latest BIOS from the HP Support website and update it.
• If BIOS update doesn't work, try a BIOS reset:
  • Turn off the laptop.
  • Press Win + B, then hold the power button for 2-3 seconds.
  • If the BIOS recovery screen appears, follow the instructions to reset.

Battery Driver Reset (Windows)

Try uninstalling the battery drivers to refresh power management:

1. Open Device Manager (Win + X → Device Manager).
2. Expand Batteries.
3. Right-click on Microsoft ACPI-Compliant Control Method Battery and choose Uninstall Device.
4. Restart your laptop (if possible) or remove and reinsert the battery.

Test with a Different Charger

A failing charger might not be sending the correct voltage when the battery is depleted, preventing it from booting correctly. Try another HP-compatible charger if you have one available.

I hope this helps. 

Take care and have a good day.

From what I see in the available manuals and available driver version, your laptop is between five and nine years old.

If that is accurate, given the issue you have brought up and the remedies you have tried, it would seem time to replace the laptop with something newer.

It is a best practice industry IT standard to replace a laptop after five years. 

I also suggest replacing it with an Enterprise grade laptop instead of a mainstream version like a Pavilion.
