SSHD went Smoothly- After 12 hours Mac Shut Down
I installed a Seagate 1 TB SSHD, using the IFixit tool kit and instructions. Mac Mini started up, everything was SAT! Start up time approximately 16:00 on Day 1. Used Mac all afternoon and evening, transferring files to second HD, the Seagate 1TB drive.
Next morning (Day 2), approximately 07:30 checked Mac. Running fine, but cooling fan sounded loud (at least I assume the noise was the cooling fan).
Next checked Mac approximately 16:20 on Day 2. Monitor screen was all white. Moving mouse would not "wake up Mac". Turned Mac off and then restarted. Mac, played its "start up tune". Screen showed white, then Apple logo with Progress bar showing underneath logo. Progress bar showed approximately 30% complete, then screen went dark.
I felt Mac, Mac felt "warm", but since I don't regularly feel the Mac, and am new to Mac I have no reference to use as to whether Mac was "too warm".
Left Mac off over night. Next time I turned it on. Mac played the "Start Up" tune and monitor screen turned on, showing first all white, then Apple logo, and finally the Progress bar. Again approximately 30% through the Mac shuts down.
I took the Mac apart, followed the iFixt installation instructions for the second SSHD. All of the connections were sound, clearly in place. Afterall, the second HD worked initially.
Used canned air to blow into fan. Fan spun with no noise.
Left base off, turned Mac over, plugged her back in and connected monitor. Turned on, heard Mac start up tune, monitor screen lit up, observed cooling fan spinning unimpeded. Again Apple logo appeared, then progress bar. Again, at the 30% progress mark the Mac shuts down, cooling fan stops spinning.
Does anyon have any ideas?
Is this a good question?
