Intel Mac :: Shut Itself Down In Sleep Mode?

Jul 2, 2012

My iMac shut itself down last night while in sleep mode.  It's rarely ever turned off.  I cannot get it started today. I'm not the most tech saavy person but can follow instructions if someone could walk me through it.   

Purchased in 2006 and has worked well until now.  AppleCare has expired.

Info:
iMac (20-inch Late 2006)

OS X :: Why Does My G-5 Shut Down My Computer In Sleep Mode

Nov 14, 2008

Could someone please explain to me why my computer is shutting down in sleep-mode. In addition, when it happens, the fan goes into hyperblow, which doesn't make sense because it would not be operating if the system were completely shut down. It acts like it is shut down but won't respond or wake up, etc. I re-loaded my system software per the Mac Store Genius' advice, but that didn't work. Is it possible that my power supply is going?

MacBook Pro :: Shut Down Or Sleep Mode When Carried Around

Aug 25, 2010

Coming from Windows sometimes I hibernate the laptop but I have heard alot of people say with Mac's that they just put them to sleep. Firstly do you just do this for short periods as such as overnight? Also can your carry them around whilst on sleep or should they be shut down.

MacBook Pro :: Double Tap Restarting After Sleep Mode / Restart / Shut Down

Oct 23, 2010

so i've been having an issue with the double tap to hi-light any text i wish to copy. Such things as double tapping the URL bar to hi-light the whole url so i can just retype w/e site i want to go to. Every time i restart or turn off or my mbp goes to sleep and i reopen it, the double tap function resets. So i'm forced to go to the system preferences > trackpad> "double-click speed" to slowest in order to get my double tap to hi-light anything again. Is there something wrong with my mbp? Or is there a way i can save the settings when i put the double-click speed to slow so that it wont reset every time my mbp needs to be woken up or restarted?

MacBook :: Laptop Holds Charge Only In Sleep Mode / Shut Down

Jul 3, 2010

I tried SMC resets and everything. The Macbook takes a charge and charges normally when it is asleep, or off. It will charge to the max (96%). Battery has 349h load cycles. Charges when asleep or off. As soon as I power on the laptop or wake it up, it will stop charging. Battery holds the normal charge I usually get (3ish hours). Tried a few pram and smc zaps. Battery charger is a Hong Kong knockoff. Battery inside is genuine. 2008 Aluminum Macbook. Cleaned magsafe and port with q-tip and still to no avail.

When plugged in, it will run *off the battery* and the charger will show a green light and not trickle charge the battery. It will drain the battery, and then when it is drained it will run off the power. Check the screen shot. I am thinking that the charger is the culprit. Because it holds a charge when I let it charge while it is off. It will charge up just fine, in the two hours or whatever it takes to charge itself up. Battery usage is normal when it is running off the battery.

OS X Yosemite :: IMac Locking Up After Sleep Mode Requiring Full Power Shut Down And Rebooting

Dec 7, 2014

iMac 27 locking up after sleep mode requiring full power shut down and rebooting in safe mode then shutting down and rebooting normally.. Permissions and this check show no errors, the only error sleep mode failure. Boot up is very slow as well as wake up when possible is slow. Yosemite seems to need a new release in order to correct the boot problems. System operates more like a Windows machine than Apple machine what's going on?

Software :: System Not Exiting Sleep Mode / Kicks Back Into Sleep Mode

Dec 29, 2009

As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.

The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.

How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.

Desktops :: Intel Imac Will Not Sleep Or Shut Down?

Apr 8, 2010

I have an Intel Imac G5 2.66 gHz 2 core duo running 10.6.3. I am unable to get it shut down or sleep. Choosing either results in the display blacking out, the fans run for about 1 second and then everything come back on as if nothing has happened. I've reset the Pram and Vram, disconnected all USB and Firewire devices, tried it with and without file sharing and Airport operating. A 'hard' shutdown with the power button works fine. I have checked for any firmware updates but mine is fine. This happened once before and clearing out some files from deleted apps cured the problem but it's back now.

Intel Mac :: Would Not Wake Up From Sleep Mode

May 5, 2012

My Mac would not turn on this morning from sleep mode. I pressed the power button and nothing. Then I did it again and heard the fan shut off inside so I tried again and up it came. Also I cannot wake my Mac up unless I press the power button. I used to press any key on the keyboard or move the mouse and it would wake up, but now that doens't work. I don't know if this could be a reason, but my mother has a horrible habit of unplugging it when it storms. It's always asleep and I've told her not to do that and to make sure it's turned off before ripping the cord from the wall. But she continues to do it when it storms.

Intel Mac :: Won't Wake From Sleep Mode

May 28, 2012

Computer would only start after sleep mode if I unplugged the power cord. The power button would not do anything, even if I held it for a long time.

Shut down and start up would work normally. Only effected sleep mode.

After much trouble shooting I found that I had a bad USB hub. Everything on the bad USB hub would work fine so I didn't suspect it.

Intel Mac :: Why Does It Often Freeze After Turning On From Sleep Mode

Apr 28, 2012

I've been using Pc's for the past 30 odd years so am totally new to Mac. I'm doing my best to adapt to this new different OS and so far have found some things more user friendly but others ? I've more or less given up on those as Mac doesn't seem to do those things. These are probably Windows based and I'm assuming Mac has its own alternatives that I haven't discovered yet. Anyway, my immediate problem is this goddamned frustrating situation when I try to re-activate the comp' after waking it from 'sleep'. Sometimes its fine but others, it comes back on but freezes and the only option I have is to turn it off at the switch and do a re-boot!

IMac (Intel) :: Will Not Come Out Of Sleep Mode On OS X Mavericks (10.9.4)

Aug 31, 2014

My iMac will not come out of sleep mode and if it does it takes a really long time to do so. I've looked at several things in other forums and it seems to be a Maverick issue. However it only started about a month ago and most people have had this issue since the release of Maverick. I also read to use the bluetooth keyboard and mouse instead of a USB one. That also did not fix the problem. So I am at a standstill ...
