Fixes to Laptop Slow After Replacing Battery

Fix 1. Check the New Battery Health and Compatibility

Although most laptops use standard lithium-ion batteries, there are still cases where new batteries are not compatible with laptops, causing lagging computer performance. So, you need to check if the battery is compatible with your laptop.

To do this, you can try to remove the battery, use the power adapter to provide continuous power to the laptop, and check if the computer is running smoothly. If yes, the battery may be incompatible with your laptop or may be damaged. In such a situation, you can purchase a new original battery that matches your laptop brand and model, and then check if the issue disappears.

Fix 2. Reinstall the Battery Driver

Outdated or incompatible battery or other hardware drivers can negatively impact laptop performance and cause the computer to freeze or lag. To rule out this cause, you can reinstall the battery driver and other problematic drivers.

Right-click the Start button and choose Device Manager. Next, double-click the Batteries option to expand it, then right-click the target device and choose Uninstall device. In the new window, hit Uninstall to confirm this operation. Finally, restart your computer, and the most appropriate driver should be installed automatically.

Fix 3. Change to the High-Performance Power Plan

If your laptop is operating in a power-saving mode, the computer performance may be negatively affected. In this case, you can change to the High-Performance power plan and check if the issue is improved.

Step 1. Open the Control Panel by using the Windows search box.

Step 2. Navigate to Hardware and Sound > Power Options.

Step 3. Choose the High performance power plan. This option ensures that the computer continues to run at a higher speed.

Fix 4. Reconfigure Some BIOS Settings

According to user experience, battery replacement is sometimes accompanied by BIOS settings resets, leading to performance loss. In this case, you can enter BIOS and check whether you need to re-optimize the settings. The steps to enter the BIOS vary depending on the computer brand and manufacturer. Most computers require you to quickly press the Esc key, F1 key, F2 key, or F12 key after turning on the computer.

So, you need to check for and uninstall the bloatware, and then the computer performance should be optimized.
