## Abstract

A hot-swappable electronic device and a method for preventing crash of the same are provided. The method includes: detecting, by a controller, whether or not the hot-swappable electronic device is in a power-on state; detecting, by the controller, whether or not a power connection port is connected to an alternating current power source when the hot-swappable electronic device is in the power-on state; detecting, by a first sensor and a second sensor, whether or not a first battery leaves a first battery installation groove and a second battery leaves a second battery installation groove when the power connection port is not connected to the alternating current power source; and lowering, by the controller, a system power consumption of the hot-swappable electronic device when the first battery leaves the first battery installation groove or the second battery leaves the second battery installation groove.

## Claims

### Claim 1

A hot-swappable electronic device, comprising:
a first battery installation groove;
a first battery installed in the first battery installation groove;
a second battery installation groove;
a second battery installed in the second battery installation groove;
a power connection port;
a controller electrically connected to the power connection port;
a first sensor electrically connected to the controller and assembled in the first battery installation groove, wherein the first sensor sends a first trigger signal to the controller when the first battery leaves the first battery installation groove; and
a second sensor electrically connected to the controller and assembled in the second battery installation groove, wherein the second sensor sends a second trigger signal to the controller when the second battery leaves the second battery installation groove;
wherein the controller is used to determine whether or not the hot-swappable electronic device is in a power-on state and detects whether or not the power connection port is connected to an alternating current power source;
wherein, when the hot-swappable electronic device is in the power-on state, the power connection port is not connected to the alternating current power source, and the controller receives the first trigger signal or the second trigger signal, the controller lowers a system power consumption of the hot-swappable electronic device.

### Claim 2 (depends on 1)

The hot-swappable electronic device according to claim 1, wherein the controller is connected to a central processing unit and a backlight source; wherein, when the hot-swappable electronic device is in the power-on state, the power connection port is not connected to the alternating current power source, and the controller receives the first trigger signal or the second trigger signal, the controller lowers at least one of an operating frequency of the central processing unit and a brightness of the backlight source.

### Claim 3 (depends on 1)

The hot-swappable electronic device according to claim 1, wherein the controller is an embedded controller, and the first sensor and the second sensor are two Hall sensors.

### Claim 4

A method for preventing crash of a hot-swappable electronic device, comprising:
determining, by a controller, whether or not the hot-swappable electronic device is in a power-on state;
detecting, by the controller, whether or not a power connection port is connected to an alternating current power source when the hot-swappable electronic device is in the power-on state;
detecting, by a first sensor, whether or not a first battery leaves a first battery installation groove when the power connection port is not connected to the alternating power source;
detecting, by a second sensor, whether or not a second battery leaves a second battery installation groove when the power connection port is not connected to the alternating current power source; and
lowering, by the controller, a system power consumption of the hot-swappable electronic device when the first battery leaves the first battery installation groove or the second battery leaves the second battery installation groove.

### Claim 5 (depends on 4)

The method according to claim 4, further comprising: detecting again, by the controller, whether or not the hot-swappable electronic device is in the power-on state when the power connection port is not connected to the alternating current power source; and detecting again, by the controller, whether or not the hot-swappable electronic device is in the power-on state when the first battery does not leave the first battery installation groove and the second battery does not leave the second battery installation groove.

### Claim 6 (depends on 4)

The method according to claim 4, further comprising: sending, by the first sensor, a first trigger signal to the controller when the first battery leaves the first battery installation groove; sending, by the second sensor, a second trigger signal to the controller when the second battery leaves the second battery installation groove; and lowering, by the controller, the system power consumption of the hot-swappable electronic device when the controller receives the first trigger signal or the second trigger signal.

### Claim 7 (depends on 4)

The method according to claim 4, wherein lowering the system power consumption of the hot-swappable electronic device includes lowering at least one of an operating frequency of a central processing unit and a brightness of a backlight source.

### Claim 8

A method for preventing crash of a hot-swappable electronic device, comprising:
detecting, by a controller, whether or not a power connection port is connected to an alternating current power source;
determining, by the controller, whether or not the hot-swappable electronic device is in a power-on state when the hot-swappable electronic device is not connected to an alternating current power source;
detecting, by a first sensor, whether or not a first battery leaves a first battery installation groove when the hot-swappable electronic device is in the power-on state;
detecting, by a second sensor, whether or not a second battery leaves a second battery installation groove when the hot-swappable electronic device is in the power-on state; and
lowering, by the controller, a system power consumption of the hot-swappable electronic device when the first battery leaves the first battery installation groove or the second battery leaves the second battery installation groove.

### Claim 9 (depends on 8)

The method according to claim 8, further comprising: detecting again, by the controller, whether or not the power connection port is connected to the alternating current power source when the first battery does not leave the first battery installation groove and the second battery does not leave the second battery installation groove; and detecting again, by the controller, whether or not the power connection port is connected to the alternating current power source when the hot-swappable electronic device is not in the power-on state.

### Claim 10 (depends on 8)

The method according to claim 8, wherein lowering the system power consumption of the hot-swappable electronic device includes lowering at least one of an operating frequency of a central processing unit and a brightness of a backlight source.
