Additionally, a second subset of keys on the embedded keyboard may be re-mapped to one or more different functions if an application running on the computing device supports keyboard re-mapping. In one example, re-mapping the second subset of keys includes grouping two or more keys in the second subset into a common function. ## Claims ### Claim 1 An apparatus comprising: logic, implemented on a hardware that is at least partially fixed, to: detect an event on a computing device having an embedded keyboard with a default mapping of keys to functions, disable a first subset of keys on the embedded keyboard in response to the event, and re-map a second subset of keys on the embedded keyboard to one or more different functions if an application running on the computing device supports keyboard re-mapping, wherein the event is to be detected based on sensor data associated with the computing device and the event is to be a physical transition of the computing device into a tablet mode, the tablet mode comprising the embedded keyboard folded behind a touch enabled display in a single piece configuration, wherein the logic is to use the sensor data to determine whether a user is grasping the embedded keyboard, and wherein the second subset of keys is re-mapped if the user is grasping the embedded keyboard. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the logic is to group two or more keys in the second subset into a common function. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the event is to be one of a transition of the computing device into an active state while the computing device is in a tablet mode or a launch of the application while the computing device is in the tablet mode. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the logic is to send a re-direct command to an embedded controller associated with the embedded keyboard. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the logic is to adjust the re-mapping of the second subset of keys in response to a physical transition of the computing device between a portrait mode and a landscape mode. ### Claim 6 A computing device comprising: a battery to supply power to the computing device;
