Because of Knox/MDM, I can't restore from a google accou. Things are working well.I am trying to come up with a solution for backing up the call logs, contacts and text messages. Hi, I am using Samsung phones and ManageEngine's MDM+ deployed from Knox. I finally gave up after about 20 hours of effort, and relegated the thing to the e-waste bin. I was able to eventually apply the software fix from that last link but it never stuck beyond 2 or 3 reboots. I had the bad luck of troubleshooting one of these that would boot to a grey screen and get unbelievably hot. software fix to disable the discrete GPU and use onboard graphics: Opens a new window re-flow GPU: Opens a new window or Opens a new window If you google the word radeongate you'll see tons of hits, complaints, articles, blog posts, and a truckload of frustration. Opens a new window Opens a new window (scroll down quite a ways for the section on the 2011 MBP with AMD graphics) This is a known issue with the early 2011 MBPs that became widespread around 2014, and Apple had a special repair program for affected users that ran to 2016. The brief white screen before the reboot could be an indication that the GPU is dying. I've posted about this one a few times before, but it's worth a re-paste: It definitely is, I have been trying to explain that is irrelevant to the performance of the machine. The owner said it is in good condition physically. I can't imagine using a machine from 2011. However, I completely agree about getting a new machine and moving on. I am unable to get into single user mode.ģ. It was old enough that is was time to move on so I bought a new Mac.ġ. I just couldn't get it to boot - turned out it was a known thing with that hardware. The behavior you describe reminds me of my how my G4 desktop mac met its demise. Last thought is that your hardware may be aged and something subtle like solder joints are loose or a chip is cracked or such. Regardless, if you get it to go there, it tells you more about the state of the machine. normally you could do something like run a check disk or possibly reset a password, but we don't know enough that either would useful. Not sure you know enough about the state of machine yet to be able to much with it. The only other thing I know to try is booting to single user mode. Not sure what the circumstances it resolves, but it is something mac people taught me to try for this kind of sitaution. > Its old enough that if there are any internal batteries for CMOS or NVRAM storage they may need to be replaced. How long since this machine was last used, powered on?
