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?

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.

The Macbook is totally frozen: the keyboard doesnt respond (caps button light wont go on and etc.) and my external monitor wont come on either.What I've tried:
-Install combo update 10.5.8 (i did normal update first time)
-Started up with all the magic keys combos (PRAM and SCM or whatever)
-Tried the fix where you need to (re)enable the ethernet port
-Set sleephibernate mode to 0
- Repaired permissions and disk aid etc.
I have a G5 (Power PC, g5, Dual 1.8 GHZ with 1.25 GB SDRAM, and Mac OS X 10.4.10-phew!) and I recently: added more USB ports using a PCI card, and purchased a non-Apple 22" widescreen display.
Prior to adding USB ports, I was using a hub that ran off its own power source, and used a Samsung 19" monitor.
My situation now: everything starts up fine, but ultimately the fan will kick in at SUPER HIGH and won't stop. I can put my Mac to sleep--which stops the fan noise--but then it won't wake up.
I have run the Apple Hardware test and everything checks out OK. I've also reset the SMU according to directions from this forum; AND I've vacuumed out all the dust bunnies.
The fan runs so loud and so high it sounds like it's an airplane that's about to take off.
Short of bringing in my Mac to a technician, can you recommend anything? My Mac has been glitch free up until now.

The last couple of times I have woken my MBP up a box has popped up with a big red sign in the middle saying my external hard drive was removed unexpectedly and could have caused loss of data. I know this is not healthy and I would like to stop it doing this as soon as possible. It is connected via firewire 800 and is a western digital 250 gig my book pro if that makes any difference. I close the lid of my laptop with it still on and connected and everything is supposed to sleep. It used to work fine, I would open the lid and everything would wake up and I could do what I was doing before with no error messages and the hard drive would still be mounted on the desktop.

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 was working on my iBook G4 and it froze up on me. When I restart, it goes to the apple and spinning wheel then goes to a blue screen and sits there. If I restart it does the same thing. The only thing I have done for it to go to the login screen and not the blue screen is let it sit of a long time then try again. I have done a hardware test and everything passed. After much troubleshooting I figured I would erase the entire disk on the OS install and start over. I get about a quarter of the way through the OS install ( i have tried Leopard and after many freezes, reverted back to the original OS disk Panther) but I get the same thing everytime it just freezes. Usually everything freezes including the mouse pointer. My only option is to restart which gets me back to the blue screen. I have gone into the hard drive via firewire target disk mode and backed everything up. ANd everything seems fine in TDM. I also erased the disk through disk utility figuring if nothing is on the disk there should be nothing left to be causing this error. So i erased everything but still freezes up on the OS install.

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?
View 2 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?

My 15'' 2.4ghz MacBook Pro will only wake up from sleep about 50% of the time. I have tried waiting for several minutes, but the only solution seems to be holding down the power button, and then restarting. Is there anything i can do to fix this?

I've lived with this as long as I care to live with this. My 17" MacBook Pro will not wake from sleep. Space key, mouse click, closing lid and re-opening, disconnecting power and reconnecting -- nothing works. When the display goes to sleep I have no alternative but to force a reboot with the power button. I can't see how this can be good for my hard drives. But to set the machine to never sleep will likely damage the display.Â
I believe my firmware is up to date. I'm running OS 10.6.8. I recently reinstalled system software and updated everything but the problem persists.Â
Here is my system info:Â I await your collective wisdom to flow over me.

I seem to be having a real run of bad luck at present! I was updating software which was going to take a while so had my dinner whilst this was happening, came back and MacBook Pro had gone to sleep and would not wake up! When i closed lid the light then came on and it would not go off however as soon as I lifted lid ...nothing. So did (another) safe reboot and hence I'm writing to communities again (twice in one day).

It's been a while now that my mac pro 13" (july 2011 version with lion) either doesn't wake up from sleep (or appears so because the screen stays turned off) or it does but when asked to log back in, I type the password and press enter, and the colored wheel shows up and stops responding...not even gets to log in. I have to hard reset with the power button.Â

I put my (early 2010, i5, 8Gb RAM, 500Gb HDD, OSX 10.7.4, all other software up to date) MacBook pro to sleep by closing the lid, it goes to sleep, then minutes or hours later I go to wake it up again by opening the lid and see the screen flash briefly (with whatever I was running before sleeping) but then the screen goes black and the MacBook does not respond to anything but a hard reset.I have done the following via tech support or my own research:
Hard drive verified and repaired (it found some folder problems but fixed them) all clear, also memory all clear (using Rember, overnight), opened it up and re-seated just in case, permissions all good. It doesn't run particularly hot either (and the issue only ever happens when it's trying to wake from sleep, so it's cold anyway). Cleared SMC, PRAM, Caches, Started in Safe mode.
I have also removed everything from my Login startup group except for EvernoteHelper and BetterTouchTool, I'm running Chrome as my browser but I tried unintsalling it and moving to Safari but this didn't help either. Issue is still happening, I would guess maybe 50% of the time I open to wake up but mostly when it has been asleep for more than an hour (the case is completely cold).
When I restart the "error report" screen comes up with the following

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 RelatedI am still having this waking up issue with my mba 13. When it sleeps for more than 1/2 - 1 hour. It doesn't seem to wake up. It normally wakes up asking my password on top of the screen. But sometimes it reboots. Today something weird happened..the welcome screen came up asking my password.
I entered it and I seen the blue desktop screen, than back to the password box. I entered my password 3-4 times.. it did the same thing. I pressed and hold the power button. Turned it off then back on. Again my outlook file under windows xp in parallels is corrupt.
Last night after I shut my MBP, I went to re-open it a few minutes later to find the computer to do nothing. If I try a hard restart with the power button it sounds like it is going to boot but nothing happens. The only real indication I have that it is even on at all is the light on the lid latch is on but not pulsating. When the lid is up the light is very faint and when the lid is closed the light is bright. I have tried most of the things i saw on the apple support site with no luck.
View 13 Replies View RelatedI've heard that Macbook Pro's have this issue, but it seems like my white Macbook is exhibiting this sometimes. It's not a lot but I've encountered it about 3-5 times now. When I just close the lid, the little white light at the front should glow and unglow. It seems like the light stayed lit so when I open the lid the screen wouldn't turn on and there is no response and I would be forced to cold boot. My Macbook is up to date, with no problem in diagnostic.
