MacBook Pro :: Resetting The PRAM - Won't Stay Asleep
Nov 2, 2009
I have a February 2008 MBP and am having issues with keeping it asleep. I currently have it set up as a desktop connected to an external monitor, keyboard and Magic Mouse (along with a variety of other peripherals) and I've recently noticed this issue. I'm running 10.6.1, I have tried everything from resetting the PRAM, SMC and repairing disk permissions to even installing a clean copy of Snow Leopard and restoring from Time Machine backup.
For power management, I have it set to never sleep, since I manually set it to sleep and don't want it sleeping on me when in use. I also have Wake on LAN activity disabled. Yet when I set it to sleep, at approximately noon the next day it wakes up by itself. I've even turned off the Magic Mouse to make sure it wasn't being moved by vibration and waking up the Mac. I'm completely stumped!
For troubleshooting purposes, I've installed a clean copy of SL without restoring TM backup to see if it's a program that's causing this issue or if it's a problem with a peripheral. I've yet to check back on it as I'm at work, but I'm hoping it's just software related. I'm at a loss as to what to do.

My Macbook Pro will not stay in sleep mode.
When I close the lid, it will go to sleep for about 5 seconds and then just continuously wake up, then sleep, then wake up etc.
If I press sleep for the menu it just wakes up again after about 5 seconds.
The battery is completely screwed and the laptop is often plugged in, but even when I take it off charge the same thing happens.

I have been having an odd problem the past couple of days. Every time I put my MBP to sleep, it wakes up immediately after the fans shut off. I have tried shutting down all of my programs and even killing of most of my process in activity monitor to no avail.

Been having a few huge issues with my new MBA 13".
#1 - Putting the laptop to sleep. I put the laptop to sleep and put it in the bag and at some point it wakes back up. If I don't remove it during the day by that afternoon/evening when I go to remove it the battery is at 0% and it's fully discharged. One day I took it out a couple hours in and the fan was blowing like mad like it had been running for a while, when I opened the lid I had a black screen and it was frozen. Disabled waked for network access but it was no help.
#2 - When the laptop goes in standby and I open it back up I get a beach ball forever - I've tried to let it go for upwards of 30 minutes and it never unfreezes, but I can move the mouse around. I ended up telling the laptop not to standby when it was plugged in to a power source otherwise I ended up always losing work.

recently had a small USB issue, so I reset my PRAM which fixed it.Now every time I boot the PRAM will reset itself. This particularly annoying because:1) It takes longer to boot as it restarts again and again (sometimes 3-4 times).2) I have the boot volume set to 0 and when the PRAM is reset it will go back to default which isn't fun [and it loud].
3) I have verbose mode on and a PRAM reset removes that as well, so I need to do the 2-finger combo [which on the bluetooth keyboard doesn't work half the time].I can't seem to fix it. I've done all the usual things (ie: manual PRAM reset with 4-finger combo, SMC reset, reseating hardware, disconnection hardware) and I've also gone ahead and installed OS X on a new volume for testing. Nothing is working and this getting a little frustrating.I try not to restart my computer, but recently I've needed to it a couple times. Apple Support doesn't know what to do and they're reluctant to send a on-site tech because they're not sure what the issue is. They want me to take my computer to the Apple Store, but (1) I don't have a car, (2) it's windy and snowing like crazy outside so there is no way I'm walking a mile to the Apple Store carrying the Mac Pro by hand, and (3) even if it was sunny outside my computer weighs a lot.Anyone know what's going on here? The computer passes all hardware tests and disk scans reveal no bad sectors.

I am desperate and really need an answer to this question. I have tried everything and had no luck.
I have a MacBook Pro (13-inch, Mid 2012) running Yosemite. Whenever I close the screen, it will fall asleep like it normally does. However, the external light will only pulse once (instead of continuously), and then I can hear the hard drive begin spinning again. The external light then stays at a constant, but the screen does not light back up.
It's like the computer falls asleep, but then only the hard drive wakes up, and stays woken up. This fact causes my Macbook to eventually use up whatever battery power it has and get warm in my backpack. The only thing I can do to preserve battery power is to shut down the whole computer and boot it up every time I need it.
Also, on a side note. My computer seems to run much slower than it did on it's native Mavericks.

If i set my displays to sleep in 1 minute (say, if I leave it on overnight, and want it to sleep pretty quickly), they both come back to life after a few minutes. Since they're bright, they absolutely illuminate the room and the S/O isn't too happy with me.
I have an Alu iMac 24", Dell 24", bluetooth mouse, external USB drive, USB keyboard. I tried switching off the bluetooth mouse, and it was no better.

I put my iMac to sleep before I go to bed and it usually stays in that state until I get up. Lately something is waking it routinely during the night. I have attempted to fix this by following the suggestions in Mac Help but I still can't get to the bottom of it.

With OSX 10.6.4 my 2.66 GHz iMac will not stay asleep. It will wake up even though the Wake for Network Access box is NOT checked in System Preferences. Why is this? This happens every night. It is becoming very frustrating.

For some reason (which I hope someone knows why) my computer started to not stay sleeping. I would go to the apple menu, select sleep, the screen goes dark but then a few seconds later the screen comes back on. I haven't changed any preferences so not sure why it's doing this.
When using screen saver it stays.

Lion makes the sleep process take a while. But after a short time my Mac Pro wakes from sleep and even though I have it set up to go back to sleep after five minutes of inactivity it never goes back to sleep. This wasn't a problem with the first version of Lion.

I had my 2008 Mac Pro unpugged for a few days. When I turned it back on the USB ports weren't functioning. I can't reset the PRAM as my keyboard is not working.

So I am one of those guys that keep my desk in the same room I sleep, but can�t stand light of any kind while I am sleeping ( I know this will eventually be a hardship for me sometime, somewhere) .
Sure I know I could just move my desk out of the room and avoid this issue but I would like your input.
I like to leave my Mac book on and open with an external display always plugged in. I do not want to shut down or put it to sleep as I want it to be available 24/7 for some type of remote access. I currently have my display set to sleep after one minute with a hot corner to activate (running on 10.6.2) however at random the displays will wake and thus cause this light eyed sleeper to also wake. I can defeat this partially by killing power to one monitor every night but there is nothing I can do about the internal display short of turning down the backlight. I have wake for Ethernet disabled. Can anyone tell me, how can I do what I need to do? What type of background events cause the display to wake and why? And how if at all, can I stop them from doing this? I just want to only be able to wake the display from suspend or power save when I press a key on an attached keyboard.

I used to reset the PRAM by restarting and holding alt+command+p+r My new iMac came with a wireless keyboard and this way of resetting is not working. Apparently the Mac starts before it hooks with the keyboard.

I have a first gen Mac Pro with a 20" Apple Cinema Display connected to it. I always leave my computer in, but I let my display sleep. My display will go to sleep fine but it will wake up randomly and then fall back asleep again after the time interval. This has been going on for a long time but it's starting to really bother me.

What does everyone mean when they say this?
What does it do?
Basically, all the general information about it.. I've been reading people's problems and I see this all the time, and I'm totally confused on what it.
Also, what is PRAM? What does resetting it do?

I have a 24" 2.66 bought in Oct 09 and it is current with updates. No matter what I do it will not stay asleep, even when I manually put in down with the power button it wakes a short time later. Is there no solution to this simple problem I know many experience?

I have a 2006 Mac Pro and recently my firewire ports stopped working (front and back). I did a little searching around found a suggestion to try resetting the Mac's PRAM and NVRAM by holding the Cmd-Option-P-R keys down while booting. I have tried this numerous times and it doesn't seem to do anything (i.e. the Mac just loads OS X and doesn't re-boot like the instructions say). I'm using a MS Wireless Comfort Keyboard for Mac. Can you reset using a wireless keyboard?
Since I wasn't making any progress with that, I was toying with bringing in the Mac to a genius bar. Never having used the genius bar before - how does it work? Do I bring the computer in and leave it with them? Do they work on it while I'm there? I don't have an extended warranty so do they charge time and materials? I'm wondering if that might get awfully expensive and if I ought to just buy a PCI-X firewire card instead.
Any suggestions?

Man, what's up with this? Shut down on my early 2008 MacPro (10.5.7) takes forever! I've tried resetting the PRAM and it did this with earlier versions of Leopard as well. I've reinstalled the OS twice, changed hard drives and wish I could fix this.

Bought a new iMac in January, have a problem with the screen saver not coming on automatically after working okay for maybe three or four days. Have had about six calls and spent many hours with Apple techs. We get things working and then after a few days the hot corners won't hold, the screen saver won't come on automatically and the computer doesn't go to sleep as set up. If I manually put it to sleep it doesn't stay asleep for very long. Shutting down or a safe boot, will make it work right again.

I've recently purchased a broken 1GHz Alum PowerBook G4 12", and the display isn't working. I have a total of two 12" PowerBook displays, and I've tested both. They've worked perfectly fine. Then I've tried reseting the PMU and PRAM, no luck, but they've attempted to work. Tried the Mini-DVI to VGA adapter with my display, still no luck. The keyboard, optical drive, and hard drive works as if it was booting, and there was always a clear chime, even when I've reset the PRAM and PMU (the beep sound when PRAM also attempted). I've inserted a Leopard install disk, and it sounded like it was working perfectly fine. Hopefully it's not a motherboard issue

I have a mid-2011 iMac (with Mavericks OS), and am doing a clean install before giving my computer to a relative. I performed a secure erase of my entire harddrive (using disk utility), reset the NVRAM / PRAM (but it only chimes once even after I tried several times), and now I get the grey screen even when I try to boot from CD, safe boot, or any other commands. I can't even get back into the disk utility.
On a side note, I have the install DVD in the DVD drive and I can't get that out.

Once asleep and enters hibernation, the laptop will not start up. Even after I hit the space bar. The "sleeping light" stops going on and off and just sticks on and the screen stays un-lit. I am then forced to shut it off, so I will hold the power button down until I hear the hard drive shut down and then start it back up.
Then one of two things happen; either it starts up nicely or it starts up and remains with no display and I am forced to hard restart again. I have found that if my external HD is plugged into the USB port upon start up it will get stuck in start up; it will keep starting up the main hard-drive and nothing happens so I have to hard shut off and unplug the external and then start again. I have been trying to keep music going on my machine to avoid hibernation, but night times kinda suck.

This has been happening increasingly. When I start up my MacBook Pro (running Snow Leopard) the system boots up (chime, etc) and all is well except at the end of the process the screen is black. If I push power button and then "S" (which puts into sleep mode), of course the screen remains black. Then pushing any key will wake the screen and all is as normal.

My late 2012 MacBook Pro overheats when asleep. The fan blasts until it shuts itself down (I get a message). This started after the most recent update. I am at 10.9.3. Also, I now have a magenta flash when starting up. Now I always shut down the computer when I am done so it won't destroy itself.
