Introduction
Is your Lenovo laptop automatically shutting down, going into hibernate, or locking itself when the battery drops to 10% or less? If so, you’re not alone. Many Lenovo IdeaPad users face this frustrating issue, especially when the battery saver is turned on. This guide will help you understand why it happens and walk you through a step-by-step solution to permanently fix it.
Summary of the Problem
When the battery level drops to around 10% on a Lenovo laptop—especially models like the IdeaPad 320—users may find that the system locks, hibernates, or even shuts down completely. Afterward, pressing the power button might not turn the laptop back on immediately, making it seem unresponsive or even dead. The issue typically stems from a combination of aggressive power-saving settings, battery saver conflicts, and hardware power management defaults.
Problem Symptoms
Here are the common symptoms users experience:
- Laptop automatically locks or shuts down at 10% battery.
- Battery saver is enabled at the time of shutdown.
- Laptop does not turn on immediately after pressing the power button.
- System feels unresponsive until the charger is plugged in.
- The issue repeats unless settings are manually changed.
How to Fix It – Step-by-Step Guide
Follow these instructions carefully to restore your laptop’s proper behavior and prevent auto shutdown or hibernation in the future.
Step 1: Power Up the Laptop
Plug your laptop charger into a power socket.

Insert the charging pin into the laptop’s charging port.

Wait for at least 2 minutes to allow the battery to stabilize.
Press the power button.

✅ This jumpstarts your system if it has gone into deep hibernation.
Step 2: Adjust Battery Saver Settings
Click on the battery icon in your taskbar.

Select Battery settings.

Under Battery saver, find the dropdown near “Turn battery saver on automatically at” and set it to Never.

Uncheck the box that says “Lower screen brightness while in battery saver”.

Step 3: Perform a Shift + Restart
Press and hold the Shift key on your keyboard.

While holding it, go to the Start menu, then click Power, and choose Restart.

Keep holding the Shift key until the blue Windows recovery screen appears.
Step 4: Boot into Safe Mode
In the recovery screen, click Troubleshoot.

Select Advanced Options.

Click Startup Settings.

Click Restart.

Press the 4 key to enable Safe Mode.
Step 5: Modify Power Options
Open the Control Panel.

In the top right, change the view to Small Icons.

Click on Power Options.

On the left panel, click Choose when to turn off the display.

Turn off the display option to Never.

Click on Change advanced power settings.

Under Advanced Settings:
Expand Hard Disk > Turn off hard disk after: Set minutes to 0

Expand PCI Express > Link State Power Management: Set to Off.

Click Apply and then OK.
Save changes and close the window.
Step 6: Disable ACPI Battery Driver (Optional)
In the Windows search bar, type This PC, choose Manage.

Go to Device Manager.

Expand the Batteries section.
Right-click on Microsoft ACPI-Compliant Control Method Battery.
Click Disable device and confirm with Yes.

📝 Disabling this temporarily helps identify if the issue is caused by the battery management driver.
Step 7: Restart Your Laptop
Now restart your Lenovo laptop normally.
Go to Start > Power > Restart.
