Systems and methods for avoiding undesired power on when information handling systems are stacked
An information handling system implemented as a convertible notebook may include a first assembly, a second assembly hingedly coupled to the first assembly, a magnet housed in the first assembly, a giant magnetoresistance sensor housed in the second assembly, a Hall effect sensor housed in the second assembly, and a management controller communicatively coupled to the giant magnetoresistance sensor and the Hall effect sensor, and configured to, based on a first signal received from the giant magnetoresistance sensor and a second signal received from the Hall effect sensor, determine a position of the first assembly relative to the second assembly.
1. An information handling system implemented as a convertible notebook, comprising:
a first assembly;
a second assembly hingedly coupled to the first assembly;
a magnet housed in the first assembly;
a giant magnetoresistance sensor housed in the second assembly;
a Hall effect sensor housed in the second assembly; and
a management controller communicatively coupled to the giant magnetoresistance sensor and the Hall effect sensor, and configured to, based on a first signal received from the giant magnetoresistance sensor and a second signal received from the Hall effect sensor, determine a position of the first assembly relative to the second assembly.
2. The information handling system of claim 1 , wherein:
the first assembly comprises a display assembly comprising a display device; and
the second assembly comprises a keyboard assembly comprising a keyboard.
3. The information handling system of claim 1 , wherein the position is one of a closed position, a notebook mode position, or a tablet mode position.
4. The information handling system of claim 1 , wherein the management controller is further configured to set a power state of the information handling system based on the position.
5. The information handling system of claim 1 , wherein the Hall effect sensor generates the second signal to indicate whether the information handling system has been opened from either of a closed position or a tablet mode position to a notebook mode position.
6. The information handling system of claim 1 , wherein the giant magnetoresistance sensor generates the first signal to indicate whether the information handling system has been opened from a tablet mode position.
7. A method, for use in an information handling system implemented as a convertible notebook having a first assembly with a magnet housed therein and a second assembly hingedly coupled to the first assembly, the method comprising:
receiving a first signal from a giant magnetoresistance sensor housed in the second assembly;
receiving a second signal from a Hall effect sensor housed in the second assembly; and
based on the first signal and the second signal, determining a position of the first assembly relative to the second assembly.
8. The method of claim 7 , wherein:
the first assembly comprises a display assembly comprising a display device; and
the second assembly comprises a keyboard assembly comprising a keyboard.
9. The method of claim 7 , wherein the position is one of a closed position, a notebook mode position, or a tablet mode position.
10. The method of claim 7 , further comprising setting a power state of the information handling system based on the position.
11. The method of claim 7 , wherein the Hall effect sensor generates the second signal to indicate whether the information handling system has been opened from either of a closed position or a tablet mode position to a notebook mode position.
12. The method of claim 7 , wherein the giant magnetoresistance sensor generates the first signal to indicate whether the information handling system has been opened from a tablet mode position.
13. An article of manufacture, comprising;
a non-transitory computer readable medium; and
computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to, in an information handling system implemented as a convertible notebook having a first assembly with a magnet housed therein and a second assembly hingedly coupled to the first assembly:
receive a first signal from a giant magnetoresistance sensor housed in the second assembly;
receive a second signal from a Hall effect sensor housed in the second assembly; and
based on the first signal and the second signal, determine a position of the first assembly relative to the second assembly.
14. The article of claim 13 , wherein:
the first assembly comprises a display assembly comprising a display device; and
the second assembly comprises a keyboard assembly comprising a keyboard.
15. The article of claim 13 , wherein the position is one of a closed position, a notebook mode position, or a tablet mode position.
16. The article of claim 13 , the instructions for further causing the processor to set a power state of the information handling system based on the position.
17. The article of claim 13 , wherein the Hall effect sensor generates the second signal to indicate whether the information handling system has been opened from either of a closed position or a tablet mode position to a notebook mode position.
18. The article of claim 13 , wherein the giant magnetoresistance sensor generates the first signal to indicate whether the information handling system has been opened from a tablet mode position.
