What is claimed is: 1. A portable computer comprising: a base unit; a cover unit pivotably connected to the base unit and movable between an open position and a closed position; and a handle pivotably mounted to the base unit, the handle forming a cross bar and at least one locking tab, the cross bar capable of abutting against the cover unit when the handle is at a fixed position, for preventing the cover unit from being pivoted open from the closed position, the locking tab engagable with the base unit for fixing the handle to the fixed position. 2. The portable computer as described in claim 1, wherein the at least one locking tab defines a positioning hole therein, a lock extends through the positioning hole to fix the at least one locking tab to the sidewall of the base unit such that the handle is at the fixed position. 3. The portable computer as described in claim 2, wherein the sidewall of the base unit defines an elongate locking hole therein and forms a fixing portion thereon, the fixing portion defines an elongate through hole aligning with the locking hole of the sidewall, the lock comprises a locking portion extending through the through hole of the fixing portion, the positioning hole of the at least one locking tab, and the locking hole of the sidewall to fix the at least one locking tab to the sidewall. 4. The portable computer as described in claim 3, wherein the lock further comprises an operating portion, the locking portion extends from the operating portion, a lockpin is formed on a free end of the locking portion, a keyhole is defined in the operating portion for allowing a key inserting therein to pivot the locking portion whereby the lockpin engages with an inner surface of the sidewall. 5. The portable computer as described in claim 3, wherein the fixing portion of the base unit forms a plate and two fixing legs connecting the sidewall and the plate, the sidewall, the plate, and the fixing legs cooperatively define a receiving space for receiving the at least one locking tab of the handle. 6. The portable computer as described in claim 2, wherein a chain is connected to the lock, the chain configured for wrapping about a fixture forms a loop on a free end thereof, and the lock passes through the loop. 7. The portable computer as described in claim 6, wherein the chain is made of steel. 8. The portable computer as described in claim 1, wherein the base unit further comprises an opposite sidewall, each of the sidewalls forms a fixing portion and defines a hole, the fixing portion defines a threaded hole in an inner surface thereof aligning with the hole, the handle further forms two fixing tabs extending from two ends of the cross bar respectively, each of the fixing tabs defines a fixing hole, two screws extend through the holes of the sidewalls and the fixing holes of the fixing tabs, and engage in the threaded holes of the fixing portions, whereby the handle is pivotably mounted to the base unit. 9. The portable computer as described in claim 8, wherein each of the fixing holes of the installing portions receives a gasket defining a round hole, the screws extend from inside of the base unit through the holes of the sidewalls and the round holes of the gaskets, and engage in the threaded holes of the fixing portions, a diameter of a rod of each screw is slightly larger than a diameter of the round hole of the corresponding gasket for keeping interferential interaction between the rods of the screws and the gaskets to prevent the handle from randomly pivoting around the screws without external force. 10. A portable computer comprising: a base unit comprising two opposite sidewalls; a cover unit pivotably connected to a rear end the base unit; and a handle pivotably mounted to the rear end of the base unit, the handle forming a cross bar configured for carrying the portable computer and at least one locking tab configured for engaging with one of the sidewalls of the base unit, the cross bar engagable with the cover unit for preventing the cover unit from being pivoted open from a closed position. 11. The portable computer as described in claim 10, wherein the at least one locking tab defines a positioning hole therein, a lock extends into the positioning hole to fix the at least one locking tab to the one of the sidewalls of the base unit. 12. The portable computer as described in claim 11, wherein the one of the sidewalls of the base unit defines an elongate locking hole therein and forms a fixing portion thereon, the fixing portion defines an elongate through hole aligning with the locking hole of the sidewall, the lock comprises a locking portion extending through the through hole of the fixing portion, the positioning hole of the at least one locking tab, and the locking hole of the one of the sidewalls to fix the at least one locking tab to the one of the sidewall. 13. The portable computer as described in claim 12, wherein the lock further comprises an operating portion, the locking portion extends from the operating portion, a lockpin is formed on a free end of the locking portion, a keyhole is defined in the operating portion for pivoting the locking portion whereby the lockpin engages with an inner surface of the one of the sidewalls. 14. The portable computer as described in claim 10, wherein each of the sidewalls forms a fixing portion and defines a round hole, each of the fixing portions defines a threaded hole in an inner surface thereof aligning with the round hole, the handle further forms two fixing tabs extending from two ends of the cross bar respectively, each of the fixing tabs defines a fixing hole, two screws extend from inside of the base unit through the round holes of the sidewalls and the fixing holes of the fixing tabs, and engage in the threaded holes of the fixing portions, whereby the handle is pivotably mounted to the base unit. 15. A portable computer comprising: a base unit comprising two opposite sidewalls; a cover unit connected to the base unit and being pivotable relative to the base unit between an open position where the computer is usable and a closed position where the cover unit covers the base unit to cause the computer being unusable; a handle pivotably mounted to the sidewalls of the base unit, the handle comprising a cross bar configured for carrying the portable computer and a pair of installing portions extending from opposite ends of the cross bar respectively, each of the installing portions comprising a fixing tab pivotably attached to a corresponding one of the sidewalls of the base unit, the handle further comprising a locking tab; and a lock configured for locking the locking tab with one of the sidewalls of the base unit to keep the cross bar riding over and abutting the cover unit to prevent the cover unit from being pivoted from the closed position to the open position. 16. The portable computer as described in claim 15, wherein the locking tab extends from a conjunction between the cross bar and one of the fixing tabs. 17. The portable computer as described in claim 16, wherein each of the sidewalls forms a fixing portion which comprises a plate spaced from and parallel to the corresponding sidewall and a connecting section connected between the fixing portion and the corresponding sidewall with a space formed therebetween, the fixing tabs each having a distal end received in one of the spaces, the locking tab having a distal end received in one of the spaces when the locking tab is locked by the lock. 18. The portable computer as described in claim 17, wherein each of the sidewalls defines a through hole, each of the fixing portions defines a threaded hole in an inner surface thereof aligning with a corresponding through hole, each of the fixing tabs defines a fixing hole, two screws extend from inside of the base unit through the through holes of the sidewalls and the fixing holes of the fixing tabs, and engage in the threaded holes of the fixing portions, whereby the handle is pivotably mounted to the base unit.
