Abstract
In response to detecting that a power adapter, having a first power rating lower than a second power rating of an information handling system (“IHS”), is coupled to the IHS and in response to a request indicating that the IHS is to be powered on, the power adapter is decoupled from the IHS so that the IHS receives power from a battery included by the IHS.
Claims22
A method comprising:
- providing an information handling system (IHS);
- providing a power adapter operable to couple with the IHS, thereby providing electrical power to the IHS;
- detecting that the power adapter, has a first power rating lower than a second power rating of the IHS, when the power adapter is coupled to the IHS;
- and
- in response to a request indicating that the IHS is to be powered on, decoupling the power adapter from the IHS so that the IHS receives power from a battery included by the IHS.
2 more elements
A method comprising:
- coupling a power adapter, having a first power rating lower than a second power rating of an information handling system (“IHS”), to the IHS;
- charging a battery, included by the IHS, with power from the power adapter;
- in response to a request to power on the IHS, decoupling the power adapter from the IHS;
- and
- powering on the IHS with power from the battery.
2 more elements
An information handling system (“IHS”) comprising:
- a processor;
- a battery;
- and
- a charging circuit, coupled to the battery, for:
- in response to detecting that a power adapter, having a first power rating lower than a second power rating of the IHS, is coupled to the IHS and in response to a request indicating that the IHS is to be powered on, decoupling the power adapter from the IHS so that the IHS receives power from the battery.
