Abstract

A battery that slides into a battery bay in a laptop computer is housed integrally with its own power converter and battery charging circuit.

Claims

1. A portable computer, comprising:

a screen member holding a computer monitor;

a base member bearing at least an array of computer keys, the base member being hingedly engaged with the screen member for movement between a closed configuration, wherein the screen member and base member are substantially flush against each other with the monitor and array not being exposed to a user, and an open configuration, wherein the screen member is not substantially flush with the base member and the monitor and array are exposed to a user; and

a battery housing removably engageable with at least one of the base member or screen member, the housing holding at least one battery and at least one AC to DC converter such that the converter is internal to the housing, the converter being electrically connected or connectable to a power cord having a first plug configured for engaging an AC power outlet, the converter converting AC power to DC to charge the battery, no electrical cord external to the housing being required to connect the converter to the battery.

2. The computer of claim 1, wherein the cord has a second plug configured for engaging a socket on the housing.

3. The computer of claim 1, wherein the cord has an end opposite the first plug, the end being disposed in the housing and not being configured for manual removal therefrom by a user.

4. The computer of claim 1, wherein the housing is formed from a unitary piece of plastic.

5. The computer of claim 1, wherein the housing is slidably engageable with a bay in the base member.

6. The computer of claim 1, wherein the base member or the screen member is formed with a cord receptacle, the cord being stowable in the receptacle when not in use.

7. A battery assembly for a computer, comprising:

a housing;

at least one battery in the housing;

at least one AC to DC converter in the housing and electrically connected and/or connectable to the battery;

at least one power cord connected and/or connectable to the housing and to an AC power outlet to provide AC power to the converter; and

an electrical connector on the housing and configured for engaging a complementarily-shaped connector on the computer to electrically engage the battery with at least one component in the computer.

8. The assembly of claim 7, wherein the housing is unitary.

9. The assembly of claim 8, wherein the housing is made from a single piece of plastic.

10. The assembly of claim 7, wherein the cord has a plug configured for engaging a socket on the housing.

11. The assembly of claim 7, wherein the cord has an end disposed in the housing and not being configured for manual removal therefrom by a user.

12. The assembly claim 7, wherein the housing is configured for slidable engagement with a bay in the computer.

13. A method for providing power to a portable computer, comprising:

rigidly engaging at least one battery with at least one battery charging power converter;

while the battery is rigidly engaged with the battery charging power converter, sliding the battery into a bay of the portable computer to power the computer; and

while the battery is in the bay and rigidly engaged with the battery charging power converter, charging the battery by electrically connecting the battery charging power converter to an AC outlet.

14. The method of claim 13, wherein the act of rigidly engaging the battery with the battery charging power converter includes disposing the battery and the component in an integrated battery module, the module being slidable engageable with the bay of the computer.

15. The method of claim 14, wherein the battery charging power converter includes at least one AC to DC power converter.

16. The method of claim 14, wherein the module is unitary.

17. The method of claim 16, wherein the module is made from a single piece of plastic.

18. The method of claim 14, wherein the module is connected to a cord having a plug configured for engaging a socket on the module.

19. The method of claim 14, wherein the module is connected to a cord having an end disposed in the module and not being configured for manual removal therefrom by a user.
