Portable information handling system housing cover portion with removeable keyboard
A portable information handling system housing secures a cover over a main portion with a keystone releasable to access the housing interior. A speaker in the housing interior operates as a keystone that releases internal components by pressing a battery against a motherboard and cooling fan. A dNPU slot accepts a dNPU card with a latch biased to a secured position and having a handle that presses away from the dNPU slot to release the dNPU card. Logic executing on processing resources of the information handling system manage allocation of tasks to artificial intelligence resources for efficient application of the resources to end user goals.

2 . The information handling system of claim 1 further comprising:
a keystone sized to fit in a gap between the keyboard rear side and a rear side of the housing main portion to hold the keyboard in position.
3 . The information handling system of claim 2 wherein the tab has an opening between the detent and the keyboard and the keystone further comprises a member extending down through the opening to hold the keyboard in position.
4 . The information handling system of claim 1 further comprising:
plural contact pads exposed at a bottom side of the keyboard and interfaced with the keyboard to communicate key inputs, the plural contact pads aligned with an opening through the housing cover portion; and
plural contact pins coupled to the motherboard and aligned with the plural contact pads to receive the key inputs.
5 . The information handling system of claim 4 further comprising:
a touchpad coupled in the housing cover portion and having a connector extending into the keyboard slot to communicate touchpad inputs; and
plural touchpad contacts exposed at a bottom side of the keyboard and aligned to interface with the touchpad connector to accept touchpad inputs, the touchpad contacts interfaced through a circuit board of the keyboard with the plural keyboard contact pads.
6 . The information handling system of claim 5 further comprising:
a circuit board included in the keyboard and having the plural contacts and plural touchpad contacts; and
a keyboard controller coupled to the circuit board and operable to detect key inputs from a keyboard scan.
7 . The information system of claim 6 further comprising:
a USB hub coupled to the circuit board and interfaced with the keyboard controller, the plural contacts and the plural touchpad contacts;
wherein the USB hub sends key input and touchpad input information to the motherboard through a common serial link.
8 . The information handling system of claim 1 further comprising:
a post extending up from the keyboard proximate an unpopulated key slot of the keyboard; and
a fingerprint reader sized to fit in the unpopulated key slot and having a flexible member positioned to bias against the post to hold the fingerprint reader in position.
9 . The information handling system of claim 8 further comprising:
a power button included in the fingerprint reader to accept a press that commands power on and power off; and
a flexible cable coupled to the fingerprint reader and terminating with connector configured to interface with the motherboard.
10 . A method for coupling a keyboard to a housing of a portable information handling system, the method comprising:
sliding the keyboard into a slot formed in the housing cover portion;
flexing a tab of the keyboard by interaction of a detent on a bottom side of the tab with a rib of the housing cover portion on an upper side of the housing cover portion; and
engaging the detent of the tab with the rib of the housing cover portion to hold the keyboard in place at the housing cover portion.
11 . The method of claim 10 further comprising:
forming and opening in the tab between the keyboard and the detent; and
coupling a keystone over the tab, the keystone having a member inserted through the opening.
12 . The method of claim 11 further comprising:
exposing plural contacts at a bottom surface of the keyboard, the contacts communicating key inputs; and
interfacing the plural contacts with a motherboard below the keyboard, the interfacing through an opening in the housing cover portion.
13 . The method of claim 11 further comprising:
coupling a touchpad in the housing cover portion; and
interfacing the touchpad with touchpad contacts exposed at the bottom surface of the keyboard to communicate touchpad inputs to the keyboard.
14 . The method of claim 13 further comprising:
interfacing a keyboard controller with a USB hub of the keyboard to communicate keyboard inputs to the plural contacts;
interfacing the touchpad contacts with the USB hub; and
communicating the keyboard inputs and touchpad inputs from the USB hub through a common serial link.
15 . The method of claim 14 further comprising:
coupling a post to extend up from the keyboard proximate an unpopulated key slot of the keyboard; and
coupling a fingerprint reader in the unpopulated key slot by engaging a flexible member positioned to bias against the post to hold the fingerprint reader in position.
16 . A system for coupling a keyboard to an information handling system housing main portion, the system comprising:
a housing cover portion having a keyboard slot and engaging the housing main portion to enclose processing components coupled to a motherboard, the keyboard slot having a rib exposed at a rear upper side side;
a keyboard having a tab extending from a top side, the tab having a detent on a bottom side, the keyboard sliding into the keyboard slot to align the rib and the tab, the tab flexing when sliding over the rib, the rib engaging the detent to hold the keyboard in position, the tab having an opening between the detent and the keyboard; and
a keystone sized to fit in a gap between the keyboard rear side and a rear side of the housing main portion to hold the keyboard in position, the keystone having a member extending down through the opening to hold the keyboard in position.
17 . The system of claim 16 further comprising: plural contact pads exposed at a bottom side of the keyboard and interfaced with the keyboard to communicate key inputs, the plural contact pads aligned with an opening through the housing cover portion; and plural contact pins coupled to the motherboard and aligned with the plural contact pads to receive the key inputs.
18 . The system of claim 17 further comprising:
a touchpad coupled in the housing cover portion and having a connector extending into the keyboard slot to communicate touchpad inputs; and
plural touchpad contacts exposed at a bottom side of the keyboard and aligned to interface with the touchpad connector to accept touchpad inputs, the touchpad contacts interfaced through a circuit board of the keyboard with the plural keyboard contact pads.
19 . The system of claim 18 further comprising:
