You have bought a new computer and found something saying “ErP Ready” in the bios. What does that mean, and should you care?

ErP stands for energy-using Product and is regulated by the European Union to ensure all systems sold within their borders meet a certain power consumption standard.

But what does that mean to an average consumer?

Quite simply, ErP Ready or ErP is a BIOS power management feature that allows your computer to enter a low-power state when not in use, saving you both energy and money. When the ErP mode is on,  your computer will automatically power down any unused devices and peripherals, such as your USB ports, optical drives, and more.

So, Should You Care about ErP Ready?

If you’re simply using your computer at home for basic tasks like browsing the web, checking email, and social media, then it probably doesn’t matter that much. However, if you’re looking to buy a new computer for your business/work and want to consume less power, then you’ll need to make sure the system is certified as ERP Ready.

Not only is it a great way to save money on your energy bill, but it’s also good for the environment. It also makes your computer run a bit cooler and may assist to last longer as there will be less wear and tear on the internal components.

How to Enable ErP Mode?

To enable the ErP mode in bios, look for an option called something like “ErP Ready Mode” or “EuP Mode.” Simply enable the feature and save your changes. That’s all there is to it!

Computers that have been certified as ERP Ready will usually include an ErP logo on the case or somewhere on the device. However, just because a computer system is not labeled as ErP Ready doesn’t mean it won’t work with the technology. In fact, most computers these days are compliant with the ErP standard.

Some computers may have ErP but it may not be listed in the bios. But it will be in action when the device is in sleep mode, hibernate mode, or shut down mode.
