    I've now seen 2 machines have a logic board failure from letting the battery run dry (which shuts the computer down). I suspect the voltage regulator based on what I've seen and reading up on what the board level repair guys are finding.

    My question is does letting the battery run out stress the voltage regulator and is this situation to be avoided at all cost? Opinions please.

    im not a expert, but as far as i know the only way to stress out a VRM is to put more power into it.

    letting the power source drain that goes into the VRM wouldn't effect it as far as wearing it prematurely.

    Apple recommends allowing your battery to run down periodicly and sit while dead for a few hrs, they even have a guild about doing it on their site.
