The electronic apparatus of claim 1, wherein the battery unit further comprising: a plurality of second ribs; and wherein the first portion has a first wall forming a first boundary between the first portion of the casing and the third portion of the casing, the second portion has a second wall facing to the first wall to form a second boundary between the third portion of the casing and the second portion of the case, the second ribs formed along portions of the first boundary and the second boundary and facing each other. 3. The electronic apparatus of claim 2, wherein the third portion of the casing of the battery unit is arranged between the plurality of second ribs. 4. The electronic apparatus of claim 1, wherein the first rib within the third portion of the casing is lattice-shape. 5. The electronic apparatus of claim 1 further comprising a display unit that is rotational for placement in a first position where the display unit is configured to lay horizontally on the housing so as to cover the palm rest portion of the top wall and in a second position where the display unit is configured to be substantially erect and expose the palm rest portion. 6. The electronic apparatus of claim 5 further comprising a keyboard positioned adjacent to a rear side of the palm rest portion, the rear side of the palm rest portion being further away from the front wall of the housing than a front side of the palm rest portion. 7. An electronic apparatus comprising: a body unit including a housing, the housing including a bottom wall and a top wall that includes a palm rest portion situated toward a front side of the housing; a display unit rotationally coupled to the body unit, the display unit to lay horizontally on the housing so as to cover the palm rest portion of the top wall when the display unit is placed in a first position and the display unit being raised to expose the palm rest portion of the top wall when the display unit is placed in a second position; a pointing device situated within the palm rest portion of the top wall; and a battery unit positioned to form a part of the bottom wall of the housing, the battery unit including a casing having an upper surface and a lower surface, the casing comprises a first portion to store a first battery cell, the first portion being formed by a first section of the upper surface and the lower surface of the casing, a second portion to store a second battery cell, the second portion being formed by a second section the upper surface and the lower surface of the casing, and a third portion positioned between the first portion and the second portion and formed by a recessed portion within at least one of the upper surface and the lower surface, the third portion being positioned under and overlapping the pointing device so that a distance between the recessed portion of the upper surface and the lower surface is less than a distance between either the first section or the second section of the upper surface and the lower surface, the third portion including a first rib arranged between the upper surface and the lower surface of the casing. 8. The electronic apparatus of claim 7, wherein the battery unit further comprising: a plurality of second ribs; and wherein the first portion has a first wall forming a first boundary between the first portion of the casing and the third portion of the casing, the second portion has a second wall facing to the first wall to form a second boundary between the third portion of the casing and the second portion of the case, the second ribs formed along portions of the first boundary and the second boundary and facing each other. 9. The electronic apparatus of claim 8, wherein the third portion of the casing of the battery unit is arranged between the plurality of second ribs. 10. The electronic apparatus of claim 7, wherein the first rib within the third portion of the casing is lattice-shape. 11. The electronic apparatus of claim 7 further comprising a keyboard positioned adjacent to a rear side of the palm rest portion, the rear side of the palm rest portion being further away from the front side of the housing than a front side of the palm rest portion. 12. The electronic apparatus of claim 7 wherein the third portion of the casing of the battery unit excludes any battery cells and includes wiring for electrically connecting the first battery cell stored within the first portion with the second battery cell stored in the second portion. 13. The electronic apparatus of claim 12 wherein the battery unit further comprising a circuit board electrically coupling to the first battery cell of the first portion with the second battery cell of the second portion. 14. The electronic apparatus of claim 13 wherein the circuit board is situated within the first portion of the casing of the battery unit. 15. The electronic apparatus of claim 7, wherein the battery unit further comprises: a connector; and a circuit board electrically coupled to (i) the connector, (ii) the first battery cell stored within the first portion of the casing, and (iii) the second battery cell stored within the second portion of the casing. 16.
