## Abstract

In example implementations, a hinge is provided. The hinge comprises a first hinge plate having at least one opening, where the first hinge plate is coupled to a system cover via at least one fastener fitted through the at least one opening. The hinge comprises a second hinge plate movably coupled to the first hinge plate, where the second hinge plate comprises a tab member that is coupled to a display cover via an insert molding process. The hinge comprises a hinge cap to enclose a portion of the first hinge plate and the second hinge plate that are movable coupled.

## Claims

### Claim 1

A hinge, comprising:
a first hinge plate comprising at least one opening, wherein the first hinge plate is coupled to a system cover of a mobile endpoint device via at least one screw fitted through the at least one opening;
a second hinge plate movably coupled to the first hinge plate, wherein the second hinge plate comprises a tab member that extends in an opposite direction of the first hinge plate, wherein the tab member comprises a solid shape free from openings and is coupled to a display cover of the mobile endpoint device via an insert molding process; and
a hinge cap to enclose a portion of the first hinge plate and the second hinge plate that are movably coupled.

### Claim 2 (depends on 1)

The hinge of claim 1, wherein the at least one opening of the first hinge plate is located on an extended member portion of the first hinge plate.

### Claim 3 (depends on 2)

The hinge of claim 2, wherein the tab member and the extended member portion of the first hinge plate do not overlap.

### Claim 4 (depends on 1)

The hinge of claim 1, wherein the tab member comprises stainless steel.

### Claim 5 (depends on 1)

The hinge of claim 1, wherein the first hinge plate and the second hinge plate are movably coupled to allow gating of the system cover and the display cover.

### Claim 6

An apparatus, comprising:
a display cover enclosing an electronic display;
at least one hinge comprising a first hinge plate movably coupled to a second hinge plate, wherein the second hinge plate comprises a tab member that extends in an opposite direction of the first hinge plate and is coupled to the display cover via an insert molding process, wherein the tab member comprises a solid shape free from openings; and
a system cover comprising a keyboard and enclosing a plurality of electronic components, wherein the system cover is coupled to the first hinge plate via at least one screw.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein the tab member comprises stainless steel.

### Claim 8 (depends on 6)

The apparatus of claim 6, wherein the first hinge plate comprises at least one opening on an extended member portion of the first hinge plate and the at least one screw is fitted through the at least one opening to couple the system cover to the first hinge plate.

### Claim 9 (depends on 8)

The apparatus of claim 8, wherein the extended member portion and a tab member of the second hinge plate do not overlap.

### Claim 10 (depends on 7)

The apparatus of claim 7, wherein the apparatus comprises a laptop computer.

### Claim 11

A method comprising:
providing a hinge comprising a first hinge plate movably coupled to a second hinge plate, wherein the first hinge plate comprises at least one opening, wherein the second hinge plate comprises a tab member comprises a solid shape free from openings and extends in an opposite direction of the first hinge plate;
inserting the tab member into a mold of a display cover;
filling the mold with a metal to form the display cover around the tab member; and
coupling the first hinge plate to a system cover via at least one screw that is inserted through the at least one opening of the first hinge plate.

### Claim 12 (depends on 11)

The method of claim 11, wherein the metal comprises melted magnesium.

### Claim 13 (depends on 11)

The method of claim 11, wherein the tab member comprises stainless steel.
