View 9 RepliesI recently purchased a Mac mini As you all know, the Mac mini has its power on button in the rear of the computer. Due to a stroke I am in a wheelchair and my right side is paralyzed. This means that I have to have my mother or brother turn on the Mac mini for me. Does anyone know of a push button type of device that I can use to power on, and off, my Mac mini? While "push button" would be nice, the powering on device can be a switch. I fully realize that I can leave the Mac mini running 24/7 which I do very often. However, during thunder storms I like to shut the Mac mini off entirely. I do not want to take any chances. I know of a few people (including me with my old Power Mac) who left their computers on during a thunder storm and their computers got zapped.

I've had a MacBook for nearly 2 years and recently convinced my parents to switch from a PC to an iMac. I've managed to get everything up and running with the exception of our scanner which is an Epson Perfection 1640SU.When I push the scan button on the scanner, the computer recognizes the scanner and comes up with a preview. I can make adjustments with the menus but I can not actually push the "scan" button because it is grayed out. I've attached a screenshot so people get an exact idea of what I'm dealing with.

Have an old MBP. Just installed lion on it today. Previously, the computer had no password (at login, I would just hit enter so essentially the password was nothing). After installing Lion, that no longer works, and now I can't get into my computer.

View 3 Replies View RelatedI have a strange problem with my late-2008/early-2009 MBP. In the last couple of days, I have been using it and the screen goes black suddenly. It happened once for just a few seconds and then recovered, but today it completely shut off-- even though the battery was mostly charged (and I had received no warnings)-- so I had to reboot.
A few possibly relevant facts about this computer and this incident:
1) I've had it over a year and never had this problem before.
2) I had the logic board replaced recently because of an issue with sleep mode. This problem never appeared before the logic board was replaced (although this may be a coincidence).
3) Both times the problem happened this week, the computer was running on battery power.
4) Earlier this week (before the incident), I got a little warning to "Check battery" or something similar. The warning went away, though. Maybe this is a faulty battery issue?
5) When the computer completely shut off, it was also running a Time Machine backup. I noticed that TM has been having trouble today-- giving warnings about errors. Not sure if this could be related.
My comp. has worked perfectly, Then I installed some updates, Itunes i think? And the comp. Shut down, and when it restarts it works for a min or two, then freezes, and i get the beach ball, that just spins around and around forever.
if I don't try to open anything, or do anything when i restart it, it will just shut down, and restart, then when it comes to the Grey screen with the apple and the little circle below it, the circle looks all pixilated, and just freezes
that is the version its on (Taken two days ago, and sent to a buddy for other reasons completely)

My macbook is turned off, when I press the power button the light goes on and the computer starts making sounds of turning on for about half a second and than shuts off. I tried removing the battery and putting it again, I tried to hold the power button (the light flickers at one point and eventually shuts off as well after 2 seconds), and tried turning it on with the adapter plugged in and unplugged.

The power cord was unplugged, although the battery was fully charged. I plugged in my Canon printer for the first time in over a year. It printed half a document, then the computer shut down. I pushed the power button and got the start up chord, but then it shut down again. Tried this a few times. Then I unplugged the printer and plugged in the power chord. it started, but it's very slow, and I keep getting the pinwheel.
Recently my MBP retina late 2012 started crashing with the screen going all black leaving the keyboard lights on. I had to force it to restart. After a couple of attempts I could finally access the computer for about 10 min before it crashed again, during which i could see the logs. As of know it has been on for 1 hour without any issues but when I run some more hardware-intense programs it crashes. Since i bought the computer from a private person without insurance im not entitled to the 3 year warranty.
Im getting these errors:

My MacBook Pro will not start. It chimes and the gray progress bar starts and then the computer shuts off. I am able to start it holding the Command +R keys and access Disk Utility. That is where it says my S.M.A.R.T. drive is "failing". I have a backup from Time Machine from a week ago. I am concerned the computer is going to die. What should I do and is my computer going to die?.

The computer starts just fine, with the bong sound within seconds the computer shuts down. Is it a PSU problem? I need to be sure, before ordering a replacement. The computer is pretty old, G4 MDD.
