IMac :: Sleep / Hibernation And USB Becomes Unresponsive
Jan 23, 2009
I have an iMac (20" 2.4 g, 3 gig ram, os 10.5.6) that has recently stopped waking up after a long night of sleep. I have also found that the mouse and keyboard become unresponsive if the mac does wake up. The mouse has power, but the keyboard does not show any sign of life. The mouse glows red, but when I hit caps-lock, the little green light doesn't come on. I have tried switching ports, but no dice. As I said, the USB port clearly is sending power to the mouse, but not accepting any input. When I restart, all is well on most occassions, but the problem has persisted, once or twice, after a re-boot.

I recently bought a refurb iMac G5 with Os 10.4.11 - It has worked fine and now all of a sudden it will randomly go black as if hibernating and takes a few moments to come back on. It doesn't do it often, usually when I'm playing a video clip on the web for some reason, but not always.

I just got a 13" MacBook Air and I'm having an issue with it; googling around I've seen slightly similar problems, but nothing identical to what is going on with mine. I have the trackpad set to use the "tap to click" option in System Preferences and I've noticed that after I sleep the machine and wake it again, something gets bungled with it. The tap to click either stops responding entirely, requiring that I use the regular physical click instead, or it's highly, highly unresponsive. I've seen other reports of erratic clicking and the mouse moving on its own after sleeping the laptop.
Which thankfully mine isn't doing, but I haven't seen anybody reporting this slightly more demure issue. In any event, rebooting the machine fixes the problem completely until I sleep it next. I'm not 100% convinced that this is an Air issue, however, since I think it affected my 15" MacBook Pro to a lesser degree right after I upgraded that machine to 10.6.5, but I can't be entire certain of that since I no longer have that laptop and rarely used it without an external mouse in the first place.

MacPro 12 Core is going into sleep mode (so it seems) and becomes unresponsive requiring a hard reboot by holding the power button. Did this on a new user account I created, then it did it in Recovery Mode while using Disk Utility to repair the drives. I was about to try reinstalling OS X but it seems that this maybe a hardware problem if it happened in Recovery mode. Is my thinking right, or could it still be software? Trying to run Hardware test (D on startup) but can't get it to work so far.

So, sometimes when I wake my SR 2007 15" MBP from sleep, the keyboard and trackpad are unresponsive and I have to reboot several times before they work. I googled the problem and looked around here and didn't find any solutions.

Background info:
A few weeks ago I upgraded from a regular macbook to a brand new macbook pro 2.66 ghz. I replaced the hard drive right away with a 500gb one (had it done by apple). So my machine runs snow leopard now, I used the data transfer mode to basicly copy the data and apps from my old macbook to the new MBP.
The "problem"
It all worked fine and smooth until a week ago ...For a week now I have a problem that really concerns me. Whenever I open my laptop from a sleep mode he gets really slow and unresponsive to my commands. Its like its crashing, all I can do to get out of this is a hard reboot.
However .. during a reboot OR a cold bootup the MBP gets stuck in the grey screen with only the apple logo .. after a minute or 3 it will start loading but it will never reach the login screen... The strange thing is that when I do reboot it over and over again .. it eventually will boot normally and when it does the MBP runs fine .. until I turn it off or put it in sleep mode .. then the nightmare will start again.
What I have done
I personally suspects the Hard Drive to be the culprit, I get the feeling that the Hard Drive is having trouble starting up or getting out of sleep mode. I am not sure tough.
I have done the following:
- Disc Utility (gives no errors)
- Booting up in terminal and run Disc Utility there (repaired a volume issue)
Could this be a leopard issue? I actually can't remember if this issue happened after the last macOS update or not ..I never had a problem with my iBook and Macbook so I have little experience on troubleshooting. So I hope you more technical experienced users can give me some tips on what to do here.

I leave my imac on at night, from screensaver it goes to a black screen but I have selected that the hard drive never goes to sleep. In the morning when I click the mouse or a button on the keyboard it shows me a frozen screensaver screen and the imac is totally unresponsive. Have run disk utility and everything seems totally fine there. It is impossible to use the force quit option so have to resort to switching the whole thing off from the power button.
The software is all up to date and since disk utility shows everything in perfect working order I am puzzled what this is. A corrupt file or app? I am not a heavy user so no games installed - only software installed is the caffeine app, microsoft office for mac which is compatible with my imac, skype and that's all. Lots of free space on the hard drive too. I am not an expert on macs so I don't know how to look in case something in specific causes this that I can uninstall.

Because it happened to me a few times where the cursor will skip or one time the cursor wont even move or be responsive with my finger. The weird part is that once I exit safari the trackpad seems to work again perfectly. Also not sure if its because I have sweaty hands and my fingers are too wet? But its not something excessively sweaty or nasty just a lil moisture I guess on my finger tips at times.
Update: Never mind, found out the culprit istat pro.

I just got a generic usb keyboard to use with my mbp as schoolwork is taking its toll on the keys and I wouldn't mind preserving it a little better.
This keyboard is the dynex from bbuy that's labeled in windows crap but was cheap and works fine on the mac. Unfortunately, everytime the mbp comes out of sleep, the keyboard is unresponsive and i have to set it up again in settings.
Just hoping there's a simple fix and that it's not terminal
thanks in advance.

it took so LONG to sleep my macbook when closing the lid, and I wanted to eliminate security concerns with the sleep image being on the hard drive, so I tried that SmartSleep preferences panel, latest version. It worked for awhile (this is on Snow Leopard. But now it hibernates every time again! I've tried resetting the setting to something different, then back to just "sleep".

I have been experiencing some unusual problems with my imac. While on the internet today my computer crashed on me twice, the first time the screen just showed a bunch of vertical lines, the second it flashed some random colors then went black. After the screen change the computer was unresponsive. I have a bad feeling, is it due to overheating, a bad logic board or something else. This is the first time I have ever experienced this on a mac. Has anyone had any simiar issues? Or am I up **** creek? I can't really afford a new computer seeing that I just bought an iPad (it comes Saturday). I am not sure if my computer is still under apple care and even if it was I won't get it back by the time I have to go back to college. I attached a screen shot of my computer temps.

I have a 2.4 gig intel core 2 duo imac running S.L., with all the software updated.
Quite often, mail and itunes just freeze up and I get the spinning rainbow colored wheel.
It happened before my clean install of S.L. also.
Ive deleted pretty much all of non-essential files and programs, but still cant resolve this.
Could this be a hardware based issue, or could it still be something I am running on here ?

I recently upgraded my last-gen macbook to a macbook pro 13". I have a feeling there's something wrong with the battery however. On my old Macbook, whenever i let the battery drain completely (After I got the 10 minute warning message), the macbook went into hibernation until I plugged it in. However, on my Macbook pro, whenever I do the same it doesn't go into hibernation. Is there something wrong with my battery or have apple changed how this works?

Our 1.5 year old iMac (20" iMac, 2.4GHz Core 2 duo, otherwise known as "iMac 8.1") has started to act really strange: the busy "beachball" popping up all the time, things lagging behind or being very unresponsive (e.g. I might access an application's menu or press a window button and won't get any response until a minute later). Booting is also an issue: often times the white screen which appears with the startup chime stays there forever with that spinning circle. Other times all seems well and the Finder desktop with the dock appears, but the Finder menu bar never shows up (or appears 20 minutes later!). I've also had instances when a large folder icon with a question mark on it appears right after the startup chime (I take it this means that a bootable drive isn't found or isn't working).
Strangely there are instances when everything works as it should. But something is obviously wrong with it. So what else have I tried in order to rectify or indicate where the problem lies:
- reinstalled MacOSX from the DVD while keeping the user data
- reinstalled MacOSX from the DVD, completely erasing the internal hard drive first (I've back up my user files on an external Time Machine hard drive)
- run "Apple hardware test" from the MacOSX installation DVD. No indications of damaged RAM.
- removed the 4GB memory upgrade (two 2GB DIMMs) and replaced it with the 1GB DIMM that came with the iMac when we bought it
- ran "Disk utility", checking the drive for errors, SMART status and permission issues
- booted into Safe mode (CMD-S while booting), then entering: applejack AUTO restart to do a deep fix/check of the drive
- done several PRAM resets (CMD-ALT-P-R while booting up, a couple of times after each other, repeating the startup chime)

Last month I removed my super drive from my MBP i7 and replaced it with an SSD using the New Modus caddy. This was done so I could place a 1TB Scorpio Blue in the HDD bay. Last night, I left my computer on, and I must have accidentally pulled out the power cord. When I tried to wake it, nothing happened, so I reattached the magsafe and, low and behold, OSX would not load. I restarted with the same result - the grey and black startup wheel spins continuously (not the rainbow beachball) and the OS wont load. In response I attached my external superdrive and ran disk utilities on the SSD drive, which contains the OS. Apparently, the drive is corrupt and cannot be repaired. Disk utilities displays a "B-tree" error and recommends that I reformat the drive after removing any files that I am able to.
is there anyway that I can repair my SSD without reformatting? I thought about swapping my HDD from my old MBP for the Scorpio Blue drive and selecting it as the start up drive so I could try to transfer files, but its not a S-ATA connection. Would Disk Warrior or something similar be more effective at repairing the drive than Apple Disk Utility?

just purchased a new 27" Quad core i5 and it takes about 5 seconds for it to go to sleep, and then makes a loud noise after.
My hard drive is also noisy, it whines and drums constantly.
I also have got yellow tint on all sides of the screen.
I live in NZ so if i will not get a new replacement, instead it will be sent away to apple which will take forever
by the way it is the older 27" (late 2009) version.

It used to go to sleep without any problems after 20 mins or whatever I had set it to, but recently it won't do it. I repaired permissions, zapped the PRam and turned off my 3rd party screen saver but still no change.

I wanted to know if anyone else is having this issue.
It fails to sleep after the given time. Screen dims but I can still hear it running.
If I manually put it to sleep, it clearly makes noise (hard drive parks heads).

I just received my new iMac and everything looks great and seems to work fantastic compared to my 9 year old Power Mac G4. I set in my System Preferences under "Energy Saver" for my Mac to go to sleep (Hard Drive) after 20 minutes. My Mac does turn the monitor off but it doesn't go to sleep unless I choose "Sleep" when leaving my computer.

I assume that this could be a problem with my graphics card or RAM? I am trying to get some advice here before going to Apple since I work at home and I really can't afford lost productivity while they hang on to the computer for two weeks.

I have set it (10.5.6) to sleep after 1 minute, but it never goes to sleep. No External drives attached, iTunes sharing turned off etc. Though I never needed to turn off sharing of any kind before to get it too sleep.

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.

I recently had a hard drive failure in my imac which i replaced with the the samsung drive listed below and a fresh install of snow leopard. Now i am experiencing a problem when waking my mac from sleep. about 50% of the time when it wakes it will immediately freeze which can only be resolved by a reboot. Could this be caused by this new drive being a "green" drive that conserves more energy when asleep by going into a slower state than a typical drive or is this a software issue?

4 g ram

Whenever I put my iMac to sleep it comes out of sleep immediately but the second time it goes to sleep and stays asleep.
I believe this is due to the bluetooth mouse I'm using however I have the setting to allow bluetooth to wake the mac turned off. Is there anyway I can pinpoint exactly what's causing this.

I have a C2D iMac about 3 years old, with 10.6 and all the updates. I have it set to go to sleep after 30 minutes of inactivity. Sometimes at night I will use it to listen to a podcast or watch a TV show. When I do this, it never goes to sleep. It's always still on when I wake up. The display will sleep, but not the computer. I can put the computer to sleep myself through the Apple menu, but it never sleeps due to inactivity.
I'm worried that having the computer on 8 hours a night due to this problem will shorten its lifespan. Does anyone have an idea of what may be causing it? Does it have something to do with webpages being open? I always have Safari open. It's easier to leave pages open than it is to go through dialog boxes and menus to create and delete bookmarks all the time.
