Hybrid power
The Hybrid power feature enables your computer to function optimally during the following instances of heavy loading.
Examples of heavy loading include:
•
Graphics and processor-intensive applications and/or gaming
•
External power loading from devices relying on your computer as a power source such as gaming mice, keyboards, external
speakers, and headsets
When during instances of heavy loading, system performance is maintained through hybrid power. Hybrid power coordinates
the power drawn from the power adapter and battery, allowing power to be drawn from the battery for up to five percent per
hour with the power adapter plugged in. This feature is disabled when the battery falls below 20 percent charge.
The following table shows the different scenarios and benefits of hybrid power:

Feature description
When the battery charge reaches 100 percent and the power
adapter is plugged in, battery stops charging to avoid
lithium-ion degradation.
Under heavy loading, hybrid power is enabled and battery
charge will deplete to maintain system performance.
If your computer is no longer under heavy load, battery will
resume charging.
Hybrid function is disabled.
Computer will throttle during heavy loading and may
encounter performance issues.
