It’s really annoying when your laptop shuts down suddenly, especially if you need it to stay on. If your laptop turns off as soon as you unplug it, it might disrupt your work. It’s a problem that doesn’t only come from old batteries, which is confusing.
It’s tempting to think a bad battery is to blame. But the trouble might come from your laptop’s settings, hardware issues, or outdated BIOS. After updates, like Windows 10 version 1809, these problems happen more. So, what’s causing your laptop to turn off, and how can you fix it?
Common Causes of Laptop Shutdowns When Unplugged
It’s critical to know why your laptop turns off when it’s not plugged in. This helps keep it running well and battery life long. Let’s look at common reasons.
Battery Degradation
Battery life greatly influences how your laptop works. Over time, batteries can’t hold a charge because of chemical damage. This often leads to laptops turning off by themselves when not connected to power. It’s a normal process but usually the main issue.
System Settings Misconfiguration
Setting up your laptop the wrong way can cause problems too. Using more powerful graphics can drain the battery faster than it can charge. Also, wrong power saving settings might make your laptop shut down on its own.
Hardware Issues
Hardware problems can make your laptop shut down suddenly too. Issues like broken parts, loose connections, or old drivers stop the battery from working right with the laptop. It’s key to check that all hardware parts are in good shape.
Power Management Settings
Wrong power management settings might be why your laptop shuts off unplugged. Changing settings, like lowering processor power use in battery mode or turning on adaptive brightness, helps use less power. Using Windows Power Troubleshooter to find and fix these settings is also smart.
Diagnosing the Issue
To find out why your laptop turns off when unplugged, we need to look closely at the system. A step-by-step approach will help us figure out the problem. We’ll split this into manageable parts.
Check Battery Health
Start by checking the battery’s health. Over time, batteries wear out, causing your laptop to shut off suddenly when you unplug it. Use the tools your laptop’s maker provides to see how your battery is doing. You might find these in the BIOS or special software. Watch for signs like the battery not holding much charge or the power dropping unexpectedly.
Inspect Power Cables and Connectors
Look over your power cords and plugs next. Making sure these parts aren’t damaged and are connected right can fix many issues. Tips for troubleshooting include looking for damage or trying another wall socket. If your laptop works fine on AC power without its battery, the battery likely needs to be replaced.
Evaluate System Logs
Finally, check your system logs for clues. You can find these logs in your laptop’s event viewer or with diagnostic tools. Reviewing these logs can point out repeat errors or issues caused by hardware or software. These clues help us figure out specific fixes, like updating drivers, BIOS, or solving software problems.
How to Change Advanced Power Settings
Changing your laptop’s advanced settings can fix problems like it shutting down when not plugged in. Users noticed these issues after moving to Windows 10 or the 1809 update. Here’s how you can adjust settings to solve these problems.
Opening Power Options
Start by opening Power Options. Use the ‘powercfg.cpl’ command in the Run window. This action brings up the Power Options menu. Here, you manage settings that affect your laptop’s power use.
Adjusting Processor Power Management
In the Power Options, change the Processor power management settings. Lowering the maximum processor state on battery to about 20% is a good move. This power setting adjustment cuts down on power use, which can stop it from turning off unexpectedly.
Enabling Adaptive Brightness
Turning on Adaptive brightness also helps with battery optimization. It automatically changes your screen brightness based on the light around you. This saves energy without you having to change settings yourself. By doing this, your laptop battery will last longer.
These changes not only fix your laptop shutting off when not plugged in but also improve its efficiency. They’re beneficial for those who’ve switched from HDD to SSD or have new battery issues. Many users have seen positive results after making these adjustments.
Running the Power Troubleshoote
Using the built-in Power Troubleshooter in Windows helps fix laptops that shut off when unplugged. It checks and fixes common power issues. You can find it in the Windows Settings menu. It fixes power settings issues.
To start the troubleshooter, go to the Settings menu. Then choose “Update & Security” and select “Troubleshoot” from the side menu. Click on “Power” to start fixing the issues. The tool will automatically fix problems with battery and power management.
Adding the power troubleshooter to your fix-it routine saves time and offers an easy fix. It is great for solving usual problems like wrong system settings or old power management settings. It works for brands like ASUS, HP, MSI, Dell, Lenovo, and Acer. Using it can keep your device working without being plugged in. It boosts performance and reliability.
