I have never had a Mac Pro before, but I have owed 2 Imac's and a power mac and 2 MacBooks. The issue I am having is when I put the machine to sleep when I wake it back up it is like it does a restart. It does not start me back up where I was before.

Every hour or so, my computer freezes up and then restarts itself. Once restarted, it does an error report and tells me that "Sleep Wake" has experienced a problem. Is this a hardware problem? What I should do about it?

When I leave my new MBP alone for 2-3 hours, it shuts down and restarts, and when I wake it I am sent to the password login screen, when I enter my password the system starts like I just booted up. In energy saver preferences I have Computer Sleep set to never and display sleep set to 30 mins. Why is my computer restarting?

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.

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.

If I put my MBP to sleep (by closing the display) and then decide to use it right away (in a minute or less), are there any risks to the hard drive involved or any sort of issue?
View 5 Replies View RelatedWhen I close then open the lid on my MacBook, it will not wake up from sleep mode. I have to reboot by holding down the power button for 10 sec. When it restarts, it takes a long time to get past the gray screen with the apple logo. I also have this same problem when it goes into sleep mode, when left idle. I have since changed the settings so it will not go into sleep mode when idle in system preferences. I have reset PRAM and SMC, but the problem still persists.

For some unknown reason I will put my mac to sleep and at sometimes it will wake up without any command to wake up - why this happens and how to correct it?

I've been fighting bad sleep crashes for over a year. Sometimes it would freeze when it started sleep, sometimes when trying to wake from a sleep. I've spent countless hours researching the problem, reading everything on the boards. I tried resetting the PMU, turning off Bluetooth, removing all USB, and all of the other suggestions. Nothing alleviated the problem. Last week I replaced the lithium battery on the mother board because it wasn't keeping the correct time. So far it is sleeping and waking perfectly for the first time in ages. No more freezes or jet engine fans. I have my fingers crossed. Power Mac G5 dual 2 GHz, purchased June, 2003

My iMac is about 4 months old and about twice a month after sleeping overnight the computer will not wake up. After several attempts pressing keys on the keyboard and clicking on the mouse, I have to unplug the Mac and then press the start button on the back

View 1 Replies View RelatedMy iMac is set up wireless. Every time it's allowed to go in sleep mode, it loses wireless connectivity. Then, when I wake it up, I must go to System preferences, Network and request it to reconnect to my home wireless network. It always does this successfully, but it's quite annoying that it seems unable to achieve this on it's own. My iPad 2 and kindle can do this, why not my iMac?

I can be in the middle of using an application, browsing a web-page, or basically any type of function when it will put itself into sleep mode. When this happens, I cannot get it to "wake up". I have to disconnect it from the power source, turn it over and remove the battery, wait a few seconds, then hit the power button, put the battery back in, then restart it. This is the only way I have found that will get it to come back to life. I don't like doing it, but I really don't see what other options I have.

I've played with the sleep settings
View 5 Replies View RelatedAs 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.
I made the mistake of upgrading (funny word for what I got) to Lion, and ever since, I've had numerous issues with my trusty MacBookPro (2008, 2.4 ghz, 17"). The latest problem has been severly annoying though, and I just would like to see if any of you have some tips I could try out. Basically, every single time I close down the lid to put my computer to sleep, or even after it goes to sleep on it's own, when I go to wake my computer, it no longer is connected to my wi-fi network, and for a period of 2-5 minutes, is acts like it is searching for networks. When this exercise is over, I can use the pull down menu brought up by clicking on the wifi icon to select my network and the computer re-connects. I saw that Apple released an update for 2011 MacBookPro's that had this same issue, and this made the problem even more irritating to me since they failed to address those of us who have older computers that have the same issue. I have tried erasing all known network in the network preferences window using the plus and minus buttons, and then re-adding my network. That didn't work.

I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.

My Mac Pro 1,1 with a recently installed 120 GB OWC SSD Rev. 343A has been locking up (spinning beach ball) mostly on the "Enter your Password" screen when waking up from full sleep or displays going to sleep. I have to perform a hard reboot then it works fine, til it falls asleep and I have to wake it up. If I put it to sleep via the Menu it wakes up normally without issue. I've run Disk Utility, says it's fine. Repaired permissions. Ran the daily, weekly and monthly scripts. Cleaned my Cache with Onyx (not sure what else I could do with it)
Disksomnia is installed for FCP, to keep the disks spinning, never was a problem before. The SSD is the only major change in recent times.
Any knowledge or thoughts as to what I could do to find the problem?
Computer's up to date OS wise, 10.6.5, 12 GB Ram, Seagate 750's HDD's in the three other bays, Blackmagic card PCI, eSATA extender cable for two OWC Enclosures, other FW800 external HD's, NVIDIA Geforce 8600 GT & 7300 GT video cards for three monitors.
Having some trouble with my iMac (the version right before the intel iMacs came out. further info can be provided if needed). Running all the latest software updates etc. When I put the iMac to sleep, it goes off as normal. With the usual white light. However, when coming to wake the iMac it won't respond to the keyboard or mouse. I have to shut it down at the power button, and then turn it back on.
View 11 Replies View RelatedI put my 3 day old MBP to sleep last night with a 90% battery level (with the A/C adapter unplugged). I had calibrated the battery the day before. This morning, when I opened the lid, nothing happened. I thought this was odd. I then pressed the power button and heard about 1 second of the startup tone and then nothing. I repeated this twice more with the same result. I then plugged in the A/C adapter and the MBP booted up. The battery level was 86%. What do you think has caused this? Do I have a defective battery or something more serious?
View 22 Replies View RelatedHowever, twice now when I've run the battery down (as recommended to keep the battery healthy), and then put it to sleep and plug it in, when I try to wake it up later, it won't start. Powering on and off just lead to a little "click-whirr" and the power light pops on and off, but no action. I called applecare and they said to unplug it, take the battery out, leave it out for a bit, then put it back in, then plug it back in, and restart it. It worked (although the second such crash, it took two tries for unclear reasons). Needless to say, this is a bit frustrating. Is this a known problem? Should I do something to avoid it? Is it a lemon?

View 13 Replies View RelatedPreamble: My Quad 2.8 Mac Pro (Snow Leopard) repeatedly would not wake up from sleep. Apple Care had me reset the PRAM and maybe a couple of other things..(heck it was a couple of days ago...) and then they scheduled a repair tech to swap out the Radeon 2600 video card today. My question: If I want to have a back up video card on hand from now on, please advise model. Other than normal word processing, surfing, emailing,I only do basic photo editing with Photoshop Elements, and will be copying my 35 mm slide collection, so I don't need any that fancy, I imagine.
View 4 Replies View RelatedI have the 'dreaded' LG L246WP connected to my early 2009 mac pro via DVI to HDMI cable. Settings have always been weird on this configuration because OSX doesn't recognize the 1920x1200 native resolution unless I select 'overscan'. Now with 10.6.3 it boots up fine with the settings I've been using for over a year. However, I let my monitor go to sleep, and when it wakes up the screen is totally off-center to the left.
Also, in the preferences panel for the display, sometimes the available resolutions 'disappear' as I click them...(the value of the item in the list changes from say 1600X1200 to 0x0). I called and opened a support ticket. Their suggestion was to re-install 10.6. This may be the straw that breaks the LG's back.... Problem is now I have to research new monitors!
