Abstract
A portable information handling system keyboard is tested for wear to determine reuse or recycling by subjecting the information handling system to visual inspection performed by a camera that includes an evaluation of key wear based in part on a keyboard language in a key lattice. The key lattice couples to a keyboard frame over a membrane having contact sensors and extends plural keyboard language members towards the membrane that identify by contact against the membrane the language of the plural keys in the keyboard lattice.
Claims19
An information handling system comprising:
- a housing;
- a processor disposed in the housing and operable to execute instructions that process information;
- a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
- an embedded controller interfaced with the processor and operable to accept end user inputs from input devices and communicate the end user inputs to the processor;
- a keyboard coupled to the housing and interfaced with the embedded controller, the keyboard having a key lattice with plural keys, the key lattice coupled to a frame and over a membrane, the membrane having sensors to detect depression of the plural keys, the key lattice having a member extending down and against the membrane, the member identifying a language associated with the key lattice;
- a latch disposed in the frame and position to engage a keyboard lattice;
- and
- a snap disposed in the keyboard lattice and configured to couple with the latch to hold the keyboard lattice in place over the membrane with the plural keys aligned with membrane sensors.
The method for managing a keyboard language of a keyboard coupled to an information handling system, the method comprising:
- extending keyboard language members from a bottom side of a keyboard lattice, the keyboard language members defining a language of plural keys of the keyboard lattice;
- coupling the keyboard lattice to a keyboard frame and over a keyboard membrane;
- detecting the keyboard language members with the keyboard membrane to define the keyboard language at the keyboard membrane;
- extending the keyboard language members from a power key of the keyboard lattice;
- and
- detecting the keyboard language at the membrane when the power key presses the keyboard language members against the membrane.
A keyboard comprising:
- a frame;
- a membrane having plural contact sensors;
- a key lattice with plural keys, the key lattice coupled to the frame and over a membrane, the membrane plural contact sensors aligned with the plural keys to detect depression of the plural keys;
- and
- keyboard language members extending from the key lattice against the membrane, the keyboard language members pressing against the contact sensors to identify a language associated with the key lattice when a power key of the key lattice is pressed down to command power on.
