Does the computer work "faster" or more smoothly when plugged in? Does the computer still work slowly if you remove or unplug the battery? Apple has built in a "feature" that under-clocks the CPU in the event of a power anomaly (i.e. your blown battery) or faulty charger. If the computer works fine when the battery is removed and/or when the charger is plugged in, there is a fix. I'll wait to hear back before suggesting it, as I don't want to confuse you if that's not a solution.
