Powering off your laptop should end any running process on it. Yet, users noticed that their laptop battery drains when off. Users could verify this by monitoring the battery usage in Windows Settings.

Remember, a 1-2% drain over a day is perfectly alright, given how batteries work. But anything more than that indicates an issue that needs immediate attention.

Why does my laptop battery drain when off?

Here are a few reasons your battery drains when the laptop is off:

  • Computer is put to sleep instead of a shutdown – In some cases, users realized that the laptop went to sleep and lost charge when closing the lid. In sleep mode, processes continue to work and consume battery.
  • Fast Startup is enabled – The feature is meant to boost the Windows boot time by keeping certain critical processes running even when the computer is turned off and, as a result, leads to battery drain.
  • USB or built-in components draws power – Modern-day laptops have components, especially network cards, that draw power even when the device is turned off. Also, the USB port may be charging connected devices in this state.
  • The battery is worn out or defective – In most cases, it turned out the battery itself was defective, which caused it to drain when the laptop was turned off.

What can I do if my laptop battery drains when off?

Before we head to the slightly complex solutions, here are a few things you can do when the laptop battery drains even when it’s off:

  • Disconnect all devices from the laptop connected via a USB port and verify whether that improves the situation.
  • When turning off the computer, press and hold the Power button for 15 seconds, which puts it into a complete shutdown.
  • Check for battery issues. You may first check the battery percentage and then turn off the computer. Remove the battery, keep it this way for at least 24 hours, and plug it back in. Now see if it has more drain than necessary. Some third-party apps will help check for this.

If these two don’t work, the ones listed next surely will.

  2. Now, expand the System Devices entry.system devices
  3. Right-click on Intel Management Engine Interface, and choose Properties.properites

  5. Once done, verify if the problem is fixed.

3. Prevent your laptop from charging USB devices

There’s a setting in the BIOS that is used to configure whether the devices connected to the laptop continue to receive power when turned off or in a low-power state. It’s usually in the USB or Power Management section in the BIOS.

So, head to it and disable the setting. Remember, the BIOS interface is different for every manufacturer, but the setting is available for each, and you should be able to find it with a little effort. Once disabled, the laptop battery won’t drain when turned off.

4. Update the battery driver

  1. Press Windows + S to open Search, type Device Manager, and click on the relevant search result.device manager

  4. Once done, restart the computer for the changes to come into effect.

Updating the drivers is critical to fixing issues with components, and the same applies to the battery as well. If Windows can’t find a newer version automatically, manually update the driver.

Since this can be a tedious process, especially if you need to update several drivers, it might be helpful to use a third-party tool that is set to download and install the suitable Intel driver.

This tool can help choose the compatible software for your device and point out which of your system components need an update.

Outbyte Driver Updarer searches a large database of the most recent drivers and provides a range of trustworthy drivers from which you can choose safely and fast.

The update process itself simply takes a few minutes, and the end result is fairly reassuring, confirming that you have the right driver.
