How to Fix a Lenovo Laptop that Keeps Turning OFF (STEPS)

Why does my Lenovo laptop keep shutting off?

The main reason why your Lenovo laptop keeps shutting off is because of a dying battery, a problem with the power adapter, dirty fans, or incompatible RAM. 

  • Overheating
  • Displaced RAM sticks
  • Outdated firmware or drivers
  • Overheated power supply


Faulty power supply

Any faults in your external power source can cause frequent shutting down of your laptop. Using a higher current or lower voltage adapter can cause this problem if your device is charger-dependent. Always read the voltage listed on the power adapter to determine how much voltage the battery requires to function smoothly.


Dirty fans

When you have multiple applications in the background, your laptop’s fans constantly work to keep the heat off critical components. At some point, the heat gets too intense that the system shuts itself out to save the laptop from permanent damage.


Also, dirty fans have trouble performing well. Constant cleaning of your laptop is essential to prevent any performance issues. 


Corrupted hardware

Corrupted hardware drivers are a big nuisance. Getting your hardware component checked for any malware that can be detrimental to its performance is better. Malware may infect your system anytime, especially if you don’t have a third-party antivirus app installed.


Malware infection

Viruses can easily seep into your system. Malware infection usually stops the laptop from working smoothly. Constant restarts are a sign that something is not right with your PC. Run a thorough virus scan and check for any corrupted files or malware.


Dust and dirt

Dust in the laptop’s internal system often causes your computer to force restart. To resolve the issue, clean your internal hardware and free it from debris buildup. A hardware technician should carry out this process; cleaning your laptop will not be easy if you are a novice.



How to fix a laptop that keeps restarting?

To fix a laptop that keeps restarting, disable the automatic restart feature, update its drivers or run a virus scan. 


Update Drivers [Method 1]

The problem gets resolved to a large extent once you have updated the drivers. For that:

  1. Go to your drivers’ manufacturer’s website.
  2. Follow the instructions to install the driver.
  3. You can also update it automatically through a third-party app.
  4. Restart the PC and see if the problem has been fixed.


Disabling the Automatically Restart Feature [Method 2]

  1. Enter the Safe Mode of your computer.
  2. Press the Windows logo key + R.
  3. Now type sysdm.cpl.
  4. Click OK.
  5. Click Settings in the Startup and Recovery section under the advanced tab.
  6. Uncheck the Automatically Restart feature.
  7. Save your changes.


Run the Virus Scan [Method 3]

Another method to fix the constant laptop shutdowns is by running a virus scan.

  1. Go to the antivirus program.
  2. Run a complete check.
  3. See what applications have been flagged.
  4. Fix the problem detected by the scan.
  5. Restart the computer.


Check for Possible Hardware Issues [Method 4]

Faulty hardware can cause your laptop to restart continuously. To fix the issue:

  1. Check the RAM sticks and see that they are properly seated in their slots.
  2. Check the CPU for any dust buildup and clean it. Also, clean the processor’s fan and reboot the computer to check if the problem has been resolved.
  3. If the peripheral devices are connected, unplug them all. Plug them one by one to see which device is causing the problem.

Lenovo laptop keeps turning off when plugged in

Your Lenovo laptop keeps turning off when it is plugged in because of defective batteries, malfunctioning power outlets, or a faulty power adapter. Malfunctioning RAMs or motherboards may also cause this problem. 


To fix the issue:

  1. Change the laptop charger.
  2. Replace the worn-out batteries.
  3. Check if you need a replacement for either the motherboard or RAMs.

  7. Connect the laptop with a working power outlet.


Lenovo laptop keeps turning off during BIOS update

If your Lenovo laptop keeps turning off during BIOS update, it probably has a corrupted CMOS battery. A possible reason for constant shutting down could be overheating.


To resolve the problem:

  1. Boot the system in Safe Mode.
  2. If it keeps shutting down, start the system in Clean Boot.
  3. Perform a clean boot.


Lenovo laptop turning off when unplugged

Your Lenovo laptop keeps turning off when unplugged because of a faulty battery that couldn’t hold a backup charge for your laptop to run.


You need to:

  1. Remove the battery.
  2. And then reinstall it:
  • Go to Start.
  • Type Device Manager.
  • Open it.
  • Click Batteries.
  • Right-click on each ACPI option.
  • Select Uninstall.
  • Reboot your laptop.


If the battery is non-removable, the best option is to take your system to a service center and resolve the problem. If you try to open the panel – if the battery is non-removable – you may cause irreversible damage to your system. A technician, however, will detect the problem more easily.


Lenovo laptop keeps turning off due to overheating

Your Lenovo laptop keeps turning off due to overheating because some of your laptop components run hot. The system then goes toward a forced shut down to prevent the entire laptop from frying to death.


If you have laptops that run on fans, you should:

  1. Open the case you check if the fan blades are clogged with dust.
  2. Use a cotton swab and a small dryer to get the debris off the blades.
  3. Ensure that the debris has clear openings to go through.
  4. Once the fans are cleaned, tightly close the case.


If there are no fans in the laptop and if your device relies on conduction for cooling, you should take the device to a technician and have it repaired.


Lenovo laptop turns off when moved.

To fix the problem of your Lenovo laptop turning off whenever it’s moved, you should initiate a power drain or static drain.


  1. Power off the laptop
  2. Disconnect all power cables.
  3. Eject all peripheral devices such as flash drives, external mouse, keyboard and power cables.
  4. Hold the power button for about 60seconds; this step will drain excess voltage or flea power.
  5. Turn on the device now.
  6. Uninstall and reinstall the battery drivers.
  7. Press the Windows+X keys to access Device Manager.
  8. Select Batteries.
  9. Right-click on the Microsoft ACPI-Compliant Control Method Battery option.
  10. Choose Uninstall.
  11. Restart the device.
  12. The Windows will install the generic driver type to install the battery.


You should also check if the BIOS on your laptop is updated. If these steps don’t work, you should run the diagnostics to check if the computer is going through a hardware problem; then repair or replace the parts that are not performing.
