How can cleaning your laptop make it greener? And should you run your laptop using mains power or the battery?

Today we’ll be answering those questions as we share some laptop-specific energy saving advice.

Laptop vs desktop: Which is more energy efficient?

It probably comes as no surprise that a laptop is more energy efficient than a PC – by about 50%. So you’re already saving quite a bit of energy if you’re not using a desktop.

Should I run my laptop or battery power or mains?

There’s no real hard and fast rule about which is better, but most tech companies agree that a mix of using your laptop’s battery and connecting it to the mains is the best strategy for optimising battery life.

How often should I charge my laptop?

Fully depleting your battery’s charge to 0% is generally a bad idea. Try to connect to the mains when your battery life drops to around 20%, to preserve your battery life.

What else can I do to extend battery life?

All manufacturers agree that heat is bad for your electronic devices – this goes for phones and tablets as well as laptops. If your device has a case on it, take it off when you charge it.

Keep your device out of extreme temperatures at all times, but it’s especially important to keep your device cool when charging it.

Clean = green

If you have a laptop with an accessible battery, try cleaning it every couple of months. Give the metal contacts that connect the battery to your computer a wipe to make sure energy is transferred efficiently.

How can I reduce energy consumption?

It’s not particularly exciting, but the most effective way to reduce energy consumption it to turn off your laptop when you’re not using it. Lots of laptops also offer an ‘eco mode’ which automatically adjusts power settings to make your laptop more efficient in its energy use.
