Lenovo B40-70 and B40-80 Palmrest and Bottom Base Casing Replacement: What You Need to Know

If you own a Lenovo B40-70 or B40-80 laptop, you know how important it is to keep it in good shape. Sometimes, parts like the palmrest or bottom base casing get worn out or damaged. When this happens, replacing these parts can make your laptop look new again and help it work better. In this blog, we will talk about why you might need to replace the palmrest and bottom base casing of your Lenovo B40-70 or B40-80, how to do it, and where you can get these parts.

What Is a Palmrest and Bottom Base Casing?

Before we dive into replacements, let’s first understand what these parts are.

• Palmrest: This is the area where you rest your hands while typing. It usually includes the touchpad and sometimes buttons. The palmrest helps keep your hands comfortable while you work.

• Bottom Base Casing: This is the bottom part of your laptop. It covers and protects the internal parts like the battery, hard drive, and motherboard. It also helps keep your laptop stable when placed on a surface.

Both parts are important because they protect your laptop and make it comfortable to use.

Why Replace the Palmrest or Bottom Base Casing?

Over time, the palmrest or bottom base casing can get scratched, cracked, or broken. Here are some common reasons why you might need to replace them:

1. Wear and Tear: Using the laptop daily can cause the palmrest to wear out. The paint might fade, or the surface might get sticky or rough.

2. Accidental Damage: Dropping the laptop or bumping it can crack the casing or palmrest. This can make the laptop look bad and might cause further damage inside.

3. Malfunctioning Touchpad: Sometimes, the touchpad included in the palmrest stops working properly because of damage.

4. Heat Damage: The bottom base casing protects important parts from heat. If it is cracked or loose, the laptop might overheat.

Replacing these parts helps your laptop stay safe, look better, and feel comfortable.

• Cracks or breaks on the palmrest or bottom casing

• Loose or wobbly parts

• Touchpad not responding or acting weird

If any of these signs appear, it’s a good idea to get your laptop checked.
