Method and apparatus for selectively overriding a prepackaged power management driver of a portable personal computer so that data transmitted to the CPIU of the computer by a device, such as a "real time" serial communicators device connected thereto, is not lost during the CPUs latency "wake up" period following a CPU power-down operation. An override system stored in memory comprises an override flag which may be set or cleared by a user or the computer. If the override flag is set, then the power management system is prevented from reducing power to the CPU so that the occurrence of a CPU latency period and thus potential for loss of data is avoided.
