5th gen time capsule powers down unexpectedly

Whether or not time capsule (wi-fi) is being used it just powers down unexpectedly ( 1 to x times a day). Done a reset and made ssid visible but to no avail ( after diagnostic check help list). Also powers down when trying to make a back up to external drive. Starts up without problems when power cable is re-inserted. Doesn't get hot etc. ( thinking problem is a safeguard cut-out thing). Other than that 3 months with no probs but now this?!? Anyone with same situ? Greetz chilly

We have seen a number of reports of the Time Capsule powering down unexpectedly. You should have Apple replace the defective Time Capsule as soon as possible.

Well, I did return the Time Capsule to the Apple Store, where they exchanged it for a new one. Two days later, it too powered itself down without any known provocation. Would not respond to reset button. Pulled the plug and plugged it back in, whereupon it booted up and has run fine the past day or so. Looks like there's little point in continuing to return for exchange. Perhaps give up on the 5th Gen TC and return for refund? Apple Support say there is no known power supply issue with this device, but there certainly seems to be, in my experience.

People have solved it with a UPS.. but it does seem to be over fragile..


In a way the power supply is acting correctly.. the power dips to a point where the supply shuts off.. that is built in protection of the supply.. but it is too sensitive because an old model TC plugged into a power point next to the new TC will not power off, nor will any other equipment.


Some batches are better than others.. but the power supply in them is set to much too high a sensitivity.
