Laptop slows down after replacing the battery

High-quality laptop batteries provide power to the device to ensure it is functioning properly. But when the battery ages or is damaged, you may need to replace it. However, sometimes the laptop will slow down after replacing the battery. Here is a real case:

I recently replaced my laptop battery at a repair shop. But now the computer is running slowly and the loading speed is much slower. The performance is not as good as before. The search bar is severely stuck and the game cannot run at all. Task Manager doesn't show any exceptions, I don't know how to check.

"Laptop slows down after replacing the battery" can be caused by a variety of reasons, such as battery damage, compatibility issues, damaged battery drivers, improper power plan, wrong BIOS settings, and more. To solve this problem, you can try the following methods.

Solution

Method 1: Check the health and compatibility of new batteries

While most laptops use standard lithium-ion batteries, there are still some cases where the new battery is incompatible with the laptop, resulting in a degradation in computer performance. Therefore, you need to check if the battery is compatible with your laptop.

You can try removing the battery, use the power adapter to continuously power the laptop, and then check if the computer is running smoothly. If it is smooth, the battery may be incompatible with your laptop or is damaged. In this case, you can buy a new original battery that matches your laptop's brand and model and then check if the problem goes away.

Method 2: Reinstall the battery driver

Outdated or incompatible batteries or other hardware drivers can negatively affect laptop performance and cause the computer to freeze or stutter. To troubleshoot this, you can reinstall the battery driver and other problematic drivers.

Right-click the Start button and select Device Manager . Next, double-click the battery option to expand it, then right-click the target device and select Uninstall Device . In a new window, click Uninstall to confirm this. Finally, restart the computer and the system should automatically install the most appropriate driver.

Method 3: Change to a high-performance power plan

If your laptop is running in power saving mode, computer performance may be negatively affected. In this case, you can change to a high-performance power plan and then check if the problem is improved.

Step 1. Use the Windows Search box to open the Control Panel .

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

Step 3. Select a high-performance power plan. This option ensures that the computer continues to run at higher speeds.

Method 4: Reconfigure certain BIOS settings

Depending on the user experience, battery replacement is sometimes accompanied by a reset of the BIOS settings, resulting in a degradation of performance. In this case, you can go to the BIOS and check if you need to re-optimize the settings. The steps to get into the BIOS depend on the brand and manufacturer of the computer. Most computers require you to quickly press the Esc key, F1 key, F2 key, or F12 key after starting the computer.

Method 5: Uninstall the bloat software on the computer

Sometimes, computer slowing down is not actually caused by battery replacement, but only after battery replacement. Bloating software, resource-intensive applications, or background processes that require too much disk space and memory can also interfere with the smooth operation of the computer.

So you need to check and uninstall the bloat software, and then your computer performance should be optimized.
