What is ERP Mode in BIOS?
ERP (Energy-Related Products) mode in the BIOS (Basic Input/Output System) is a power management feature that regulates and optimizes energy consumption in computer systems.
It is designed to minimize power usage during periods of inactivity or when the system is shut down, with the goal of reducing energy consumption and promoting energy efficiency.
Enabling ERP mode in the BIOS allows the system to enter specific low-power states when not in use. These low-power states may include features such as standby, sleep, or hibernate, depending on the BIOS implementation and hardware capabilities.
In these states, certain hardware components are powered down or operate at a minimal power level, while still maintaining system functionality to a certain extent.
By utilizing ERP mode, the computer system can conserve energy, reduce electricity costs, and contribute to environmental sustainability. It is particularly useful for devices that are frequently idle or not actively used for extended periods.
ERP mode is often associated with energy efficiency regulations and standards, such as the ERP directive in the European Union, which sets requirements for energy-related products to meet specific energy-saving criteria.
It is important to note that the availability and specific features of ERP mode can vary depending on the BIOS version, motherboard manufacturer, and system configuration.
Therefore, we recommended you refer the BIOS documentation or manufacturer’s guidelines to understand the capabilities and options related to ERP mode on your specific system.

What Does ERP Ready Mean?
“ERP Ready” refers to the compliance of a product or system with energy efficiency standards and regulations, typically set by the Energy-Related Products (ERP) directive.
It signifies that the product meets the specified energy-saving criteria and is designed to operate in an energy-efficient manner.
The term “ERP Ready” is often used in the context of electronic devices, appliances, or equipment that are subject to energy efficiency regulations.
These regulations aim to reduce energy consumption, promote sustainable practices, and minimize environmental impact.
When a product is labeled as “ERP Ready,” it means that it has been tested and certified to meet the energy efficiency requirements specified by the applicable regulatory body.
It implies that the product consumes energy efficiently during various operational states, such as active use, standby, sleep, or idle modes.
By choosing ERP Ready products, consumers and businesses can make informed decisions in favor of energy efficiency and contribute to overall environmental sustainability. It helps ensure that the product aligns with energy-saving goals and meets the necessary standards for responsible energy consumption.
An important point to note here is that the specific requirements and regulations for ERP Ready certification can vary depending on the region or country. Manufacturers often provide documentation or labels indicating the ERP Ready status of their products, making it easier for consumers to identify energy-efficient options.
ERP States
In the context of energy efficiency and regulatory compliance, ERP (Energy-Related Products) states refer to specific power states that electronic devices or systems can enter to minimize power consumption and optimize energy efficiency.
ERP Ready S4
This refers to the compliance of a device with the ERP directive’s energy efficiency standards while it is in the S4 state, also known as the Suspend to Disk or Hibernate state.
In this state, the device saves the current system state to the hard disk or another storage device and powers down most components. It allows for a complete shutdown of the system while still retaining the saved system state.
When the device is powered back on, it can resume operation from the saved state on the storage device.
ERP Ready S5
This indicates compliance with the ERP directive’s energy efficiency standards when the device is in the S5 state, also known as the Soft Off or Shutdown state.
In this state, the device is fully powered off, and only a minimal amount of power is consumed for functions such as Wake-on-LAN or power button detection.
The system is completely shut down, and it requires a full boot process to resume operation.
ERP Ready S4+S5
“ERP Ready S4+S5” typically refers to a device or system that complies with the energy efficiency standards set by the Energy-Related Products (ERP) directive in both the S4 (Suspend to Disk or Hibernate) and S5 (Soft Off or Shutdown) power states.
When a device is labeled as “ERP Ready S4+S5,” it means that it meets the energy efficiency criteria specified by the ERP directive while operating in both the S4 and S5 power states.
This indicates that the device optimizes power consumption and minimizes energy usage when it is in a suspended state (S4) or fully powered off state (S5).
In the S4 state (Suspend to Disk or Hibernate), the device saves the current system state to the hard disk or another storage device and powers down most components. It allows for a complete shutdown of the system while still retaining the saved system state. When the device is powered back on, it can resume operation from the saved state on the storage device.
In the S5 state (Soft Off or Shutdown), the device is fully powered off, and only a minimal amount of power is consumed for functions like Wake-on-LAN or power button detection. The system is completely shut down, and it requires a full boot process to resume operation.
By being “ERP Ready S4+S5,” the device demonstrates its compliance with the energy efficiency requirements of the ERP directive during these two critical power states, contributing to energy savings and environmental sustainability.
