ABSTRACT:
A user-removable CPU card includes a microprocessor and a bus bridge memory controller that allows the use of the microprocessor as a central processing unit of an electrical device (e.g. notebook PC or desktop PC). The user-removable CPU card includes a first connector that can be detachably coupled to a second connector in the electrical device, when the user-removable CPU card is inserted through an opening of the electrical device. When the electrical device is powered up subsequent to such insertion, the microprocessor on the user-removable CPU card functions as the central processing unit. Inclusion of a central processing unit of a computing device on a user-removable CPU card allows easy replacement of the CPU, for example, by simply opening a door and operating an eject mechanism, without disassembly of the housing. Therefore, a user can upgrade to a new central processing unit by simply ejecting a previously inserted user-removable CPU card and inserting a new user-removable CPU card, as easily as switching diskettes in the prior art (except for powering up the electrical device after such switching).
