    PowerMac G5 power draw as fileserver

    I like using my old G5 as fileserver. I don't care about read/write speed as it's okay for streaming or daily office file use but this device is so power hungry that I see this on my powerbill. Is there a way to cap power usage of this pc or just this architecture is so bad that it needs 200W...

    Suspicious extra powerdraw? 80w unaccounted for.

    Since a few hours the powerdraw went up by a suspicious amount and I have no idea why. Activity monitor doesn't show anything new and when I enter 'powermetrics' in the terminal I get this at the end, the numbers don't seem to add up.

    I have an old Intel Mac (not sure about the model year). The power connector (MagSafe) seems to be defunct. I have tried connecting new MagSafe power but its not charging or turning on. Any ideas on what could be wrong and how to go about fixing the issue?

    Do USB-powered devices degrade MacBook’s battery while on the charger?

    If I leave USB-powered devices plugged into my MacBook while it’s charging, will it degrade the battery? What I’m trying to figure out is if the USB devices will drain the battery and then the charger recharges the MacBook repeatedly, or do the USB devices consume power directly from the MacBook...

    Power issue

    Hello, I when I walk away from Mac, it appears to disconnect networking, how do I fix this bug? There is no way Apple or any company would actually program it that way on purpose, that would be the worst feature I have ever seen in any operating system including Win 3.1. I only use ethernet...

    Curious as to whether the position of HD/SSD sleds makes any difference between slots one, two, three or four? The presence of a non-bootable—and also unrecognised 8TB HD—in the left-most position, on start-up appeared to prevent the machine from advancing beyond the chime, despite the presence...
