This question already has an answer here:
The problem I am experiencing is that if the battery is not present, the CPU is automatically throttled. I have done some searching and have found that this is apparently by design, "in case the power supply cannot supply enough power, so the machine won't shut off."
Now, here is the problem. I can't put the battery back in, because it started swelling up like crazy. I can't really justify the cost of a new battery for a machine this old and I can't really afford a new computer, so I'm stuck with this machine. It still works, but throttled back, a lot of things like flash video players are almost useless at the reduced CPU usage.
I don't really care if the machine shuts off if the supply can't keep up with power requirements. My understanding is that this really should only happen if the supply is mismatched, i.e. from an adapter designed for a smaller machine, but even if its not it is just as intolerable to have to reload netflix every 30 seconds when it loses sync than an occasional power loss would be. Besides, it is already losing power every time I need to move it somewhere.
So, what's the solution? There has to be some way to override the throttling, right?
By the way, I have already tried
sudo pmset -a dps 0 but that just gives me a usage message.
