Hybrid Power
The Hybrid Power feature enables the system to function optimally during instances of heavy loading, such as graphics and processor-
intensive gaming. It does so by coordinating the power input from the power adapter and the battery. This feature is enabled as long as
the battery capacity is above 10%.
When the Hybrid Power feature is enabled, these events may occur:
•
Battery charge does not increase when connected to the power adapter.
•
Battery charges slowly when connected to the power adapter.
•
Battery charge depletes when connected to the power adapter.
When the battery charge depletes below 10%, Hybrid Power is disabled, and this may lead to a drop in system performance. Battery
charging resumes immediately when the computer is no longer under heavy loading.
