Abstract

Examples of electronic devices are described herein. In some examples, an electronic device includes a wireless charger. In some examples, the electronic device includes a controller to cause the electronic device to enter a first power state in response to determining that a remote device is placed on the wireless charger. In some examples, the controller is to cause the electronic device to enter a second power state in response to determining that the remote device is removed from the wireless charger.

Claims (37)

1 . An electronic device, comprising:

a wireless charger; and

a controller to:

receive a first signal from the wireless charger in response to a remote device being placed on the wireless charger;

authenticate the remote device based on identity data received from the remote device via at least one of a data channel of the wireless charger or a radio communication link;

cause the electronic device to enter a first power state in response to authenticating the remote device;

cause the electronic device to enter a login mode in response to entering the first power state;

cause the electronic device to enter a second power state in response to determining that the remote device is removed from the wireless charger; and

restrict access to the electronic device in response to determining that the remote device is removed from the wireless charger.

2 . The electronic device of claim 1 , wherein the first power state comprises an awake state.

3 . The electronic device of claim 1 , wherein the second power state comprises a sleep state.

4 . The electronic device of claim 1 , wherein the remote device comprises a smartphone.

5 . The electronic device of claim 1 , wherein the electronic device is to enter a login mode in response to authenticating the remote device.

6 . A method, comprising:

receiving a first signal from a wireless charger in response to a remote device being placed on the wireless charger;

authenticating the remote device based on identity data received from the remote device via at least one of a data channel of the wireless charger or a radio communication link;

causing an electronic device to enter an awake state in response to authenticating the remote device;

causing the electronic device to enter a login mode in response to entering the awake state;

receiving a second signal from the wireless charger in response to the remote device being removed from the wireless charger; and

restricting access to the electronic device in response to the remote device being removed from the wireless charger.

7 . A method, comprising:

determining that a remote device is removed from a wireless charger, wherein the remote device comprises a keyboard;

causing an electronic device to enter an awake state in response to determining that the remote device is removed from the wireless charger;

determining that the remote device is placed on the wireless charger; and

causing the electronic device to enter a sleep state in response to determining that the remote device is placed on the wireless charger.

8 . An electronic device, comprising:

a wireless charger; and

a controller to:

determine that a remote device is removed from the wireless charger, wherein the remote device comprises a keyboard;

cause the electronic device to enter an awake state in response to determining that the remote device is removed from the wireless charger;

determine that the remote device is placed on the wireless charger; and

cause the electronic device to enter a sleep state in response to determining that the remote device is placed on the wireless charger.

9 . The method of claim 7 , further comprising restricting access to the electronic device in response to determining that the remote device is placed on the wireless charger.

10 . The electronic device of claim 8 , wherein the controller is to cause the electronic device to enter a login mode in response to determining that the remote device is removed from the wireless charger.

11 . The electronic device of claim 8 , wherein the controller is to restrict access to the electronic device in response to determining that the remote device is placed on the wireless charger.

12 . The electronic device of claim 8 , wherein the controller is to receive a signal from the wireless charger in response to the remote device being removed from the wireless charger.

13 . The method of claim 9 , further comprising causing the electronic device to enter a login mode in response to determining that the remote device is removed from the wireless charger.
