How to reset HP Envy x360 battery?

If your HP Envy x360 is not charging correctly, showing the wrong percentage or suddenly shutting down, you may be wondering: how do I reset the HP Envy x360 battery?

There are actually two different things people mean when they say “reset”:

Resetting the battery controller and power management (EC / hard reset)
Recalibrating the battery gauge so Windows shows a more accurate percentage

This guide explains both methods step by step, and also when a “reset” won’t be enough and you may need a replacement battery. If your battery is worn out or failing, you can browse compatible HP batteries here:

Important safety notes before you start

If the bottom of the laptop is bulging, or the touchpad is being pushed up, the battery may be swollen. In that case, stop using the laptop on battery immediately and do not try to “reset” it. Arrange a replacement for safety.
Never puncture, bend or overheat a lithium-ion battery pack.
The HP Envy x360 uses an internal, non-removable battery, so you should not attempt to open the pack itself—only the laptop, if you are experienced and following proper guides.

Method 1: Perform a hard reset (EC / power reset)

A hard reset (also called “forced reset”) clears residual electrical charge and resets the embedded controller (EC) that manages power. This can fix issues like:

Battery not detected
Battery stuck at a certain percentage
Laptop not powering on unless the charger is plugged in

Steps to hard reset HP Envy x360 (non-removable battery)

Shut down the laptop completely.
Click Start → Power → Shut down. Wait until all lights are off.
Disconnect the charger and all external devices.
Unplug the AC adapter, USB devices, SD card, external display, etc.
Press and hold the power button for 15–20 seconds.
This discharges any residual power and resets the internal power controller.
Release the power button and wait a few seconds.
Reconnect the charger only.
Do not plug in any USB devices yet.
Turn the laptop on.
Check if the battery is now detected correctly and if the charging indicator behaves normally.

For some Envy x360 generations, HP also provides a pin-hole “battery reset” button on the underside. If your specific model has this small hole with a battery icon next to it, you can gently press it with a paperclip for a few seconds (with the laptop off and AC unplugged). Always check your exact model’s manual before using it.

Method 2: Recalibrate the HP Envy x360 battery gauge

Sometimes the battery is physically fine, but the percentage shown in Windows is inaccurate. The laptop might jump from 40% to 5%, or shut down even though Windows says 20% remaining. In this case, recalibrating the battery can help.

Step-by-step battery calibration

Charge to 100%.
With the laptop turned on, plug in the charger and let it reach 100%. Once it hits 100%, leave it plugged in for another 30–60 minutes to be sure it is fully topped up.
Change power settings temporarily.
In Windows:
- Set the power plan to prevent sleep/hibernation on battery for a while (for example, “Never sleep” when on battery, just for this calibration).
- Optionally reduce screen brightness to avoid extra heat.
Unplug and discharge on battery.
Disconnect the charger and use the laptop normally on battery. Let it run down until it reaches a low level (for example 5–10%). Avoid forcing a hard power-off; if you can, let Windows shut down gracefully when the level is very low.
Let it rest briefly.
After shutdown, leave the laptop off for 30–60 minutes. This allows voltages in the cells to stabilise.
Charge back to 100% in one go.
With the laptop turned off (or at least not under heavy load), plug in the charger and charge it all the way back to 100% in a single continuous session.

This process helps the battery controller re-learn the real “empty” and “full” points of the pack. After calibration, the reported percentage and remaining time should be more accurate.

Method 3: Reset battery-related settings in Windows

Sometimes battery issues are partly caused by software rather than hardware. You can:

1. Reset Windows power plan settings

Open Control Panel → Hardware and Sound → Power Options.
Next to your active plan (for example “Balanced”), click Change plan settings.
Click Restore default settings for this plan and confirm.

Or, using Command Prompt (Admin), you can reset all power schemes:

powercfg -restoredefaultschemes

This resets custom power options that might interfere with charging thresholds or sleep/hibernate behaviour.

2. Update HP drivers and BIOS

Make sure you have the latest:

HP chipset drivers
HP power management / system drivers
BIOS / UEFI firmware

Outdated firmware sometimes leads to incorrect battery reporting or charging limits. Visit HP’s support page for your exact Envy x360 model to download updates.

Method 4: Run HP diagnostics on the battery

HP provides built-in diagnostics tools that can test your battery and tell you if it needs service or replacement.

Using HP PC Hardware Diagnostics UEFI

Shut down the laptop.
Turn it on and immediately tap Esc repeatedly until the Startup Menu appears.
Press F2 to open HP PC Hardware Diagnostics.
Select Component Tests → Power → Battery.
Run the Battery Check and wait for the result.

The tool will usually give you a status such as “OK”, “Calibrate”, “Replace” or similar. If it recommends calibration, follow the steps in Method 2. If it recommends replacement, no amount of “resetting” will restore the original capacity—the cells themselves are worn out.

Reset vs replace: when a reset is not enough

It’s important to understand the limitation of a “reset”:

A reset can fix: small communication issues, stuck percentages, bad calibration, minor firmware glitches.
A reset cannot fix: physical wear of the cells, high internal resistance, swelling, or chemical aging.

If your battery report shows that the Full Charge Capacity is much lower than the Design Capacity (for example, only 40–50% of original), then the cells are simply worn. You can reset and calibrate as much as you like, but the runtime will still be short.

In these cases, the real “reset” your HP Envy x360 needs is a new battery pack.

Check compatible HP Envy x360 batteries

Should you open the HP Envy x360 to disconnect the battery?

Some advanced users perform a deeper “reset” by physically disconnecting the internal battery from the motherboard for a short time. This can be useful if:

The laptop completely refuses to power on.
The battery or charger is detected incorrectly even after a hard reset.

However, this method involves removing the bottom cover, exposing internal components and carefully unplugging the battery cable. If you are not comfortable with delicate hardware work, it is safer to:

Use the software/hard reset methods above, or
Take the laptop (and a replacement battery if needed) to a professional repair shop.

Never attempt to open or modify the battery pack itself.

Conclusion: how to reset HP Envy x360 battery the right way

To reset your HP Envy x360 battery and charging system effectively:

Start with a hard reset (power/EC reset).
Recalibrate the battery by charging to 100%, discharging to a low level, then charging back to full.
Reset Windows power plans and keep BIOS/drivers up to date.
Run HP battery diagnostics to check health and see if replacement is recommended.

If, after all these steps, the battery still drains extremely fast, shuts down suddenly or HP’s tools say “Replace”, then a new battery is the only reliable solution.
