Another option would be to hold the power button down for about 5-10 seconds and simply force it to reboot. This way, you don't have to remove the battery or putz with the power cord. Whenever I can't wake from sleep...that always works for me.

Thanks for the comment. I have tried that, but this is for those instances when even that doesn't wake it up.

Thanks again for contributing.

When my MacBook Pro doesn't wake when I open the lid and then press the arrow keys, I close the lid and after making sure that the sleep indicator light is flashing, I open the lid again (and potentially press one of the arrow keys). So far this has worked for me.

Thanks, I'll give that a shot. It's a lot easier than my method.

Thanks again for the comment.

I've seen this several times where the screen was dark, but the machine was running. I couldn't see, but it was waiting for the password. If you have security on to lock the computer on sleep, then try typing your password and see if it wakes up.

Sounds like the power manage has troubles. Perhaps the next time you start up you should do a pre-emptive PRAM zap.

John

Here is an Apple document about zapping the PRAM and resetting the power manager.

PRAM holds some information about the hardware. Sometimes it gets scrambled resulting in odd behavior by the computer.

Hi John:
Thanks so much for sending me the relevant link. I will check on that and I'm sure it will helpful to other readers who come along and see it. You have certainly taught me about something I new nothing about.

Thanks for for contributing.

I've just taken receipt of my new MacBook Pro (well, as of yesterday actually.)

I had this exact same problem with my trusty iBook, which I solved with the batter removal technique...

It's a strange issue, but judging from the number of times this post has been hit, we are both not the only ones experiencing it.

Enjoy your Mac Book Pro. In spite of this annoying issue, it's the best computer I've ever owned.

Thanks again for the comments.

So far, I'm hugely impressed with my MacBook Pro.

It's so much faster than my dual G5 it's unreal.

But it's also got twice the memory, too...

___
Yea, the 2 gigs sure doesn't hurt. :)

I can run OS X and two versions of Parallels, one running Vista and one XP, with no trouble.

Since I bought a MBP 17" last December it has been experiencing this problem on a regular basis.

If you bought your MBP before November 2006, there is firmware update specifically to address this issue:

http://www.apple.com/support/downloads/macbookproefifirmwareupdate12.html

Unfortunately, it doesn't appear to resolve the issue, since my MBP said it didn't need this update, but has the problem pretty bad.

I'm dubious about the recommendation to use the "Resetting your Mac's PRAM and NVRAM" procedure. It was originally posted in 1987! I don't see how it could be relevant to our MBP's.

I'll keep you updated on my troubleshooting. I have a running log of all my MBP issues here: http://craig39.backpackit.com/pub/848874

This is great information. Thanks for adding the comment.

I did in fact update the firmware and I haven't had the problem as frequently now that I think about it, but it still does happen occasionally.

Partly, I think it also has to do with leaving the machine on constantly and just letting it sleep when I'm not using. I find it's worthwhile to give it a clean shut down every so often.

Thanks again the comment.

Unfortunately I discovered this problem for the first time while ON STAGE with "Air" (French Band) in front of an audience of 2000 people when my machine had just died... I was using it as a sampler. Nothing would wake it - needless to say it was not far short of a complete disaster. Thanks for the hints - I'm progressing through them and trying to see what caused the problem in the first place - I only have my DISPLAY set to sleep for the duration of doing live shows.

Hi Steve:

Thanks for the note.

I'm glad you've discovered a work-around for the problem because I'm sure you don't want to experience that again. I think Apple has the Sleep settings on a short leash by default to save battery life, but if you're plugged in and you know you have to use the machine for a set period of time, changing the settings is an excellent way to solve the problem.

Here's hoping you won't have to deal with that again.

Thanks again for the comment.

Hi, since l bought my MPB PRO 15" l am experiencing very big problem, l started my macbook pro with restore disk, when it began installation it asked disk 2 what l did, then, l waitted to be restated automatically, did not boot at all, just the led flashing indicating as MBP PRO IS SLEEPING l switched of, power on still nothing, now is more than 3 weeks, please need help?????
thanks

Hi:
I would recommend calling Apple tech support on this one. If the MBP isn't working, it's under warranty for a year. You should contact them and get help.

Good luck.

I just got a MacBook Pro about a month ago (Feb 2008). At least half the time it goes to sleep, it won't wake up. I have to press and hold the power key to do a full reboot. It is a huge pain, and the recent firmware update didn't do much to help. It doesn't seem to be associated with any particular program I run. But it makes my Macbook Pro very unreliable. I don't consider having to lose all my open programs and spend 5 full minutes rebooting a very good work-around. I wish Apple would address the issue (or recall the computers).

macbookprouserlikeyou

do you guys unplug or remover the battery whenever you have your mbp at home or if its power cord is connected??? my friend adviced me to remove the battery whenever the power cord is connected, put it on the mbp only when going away it makes the battery life longer...is this true?? thanks in advance......

Steve L

Hi, Thanks for posting this issue. My Feb 2007-purchased MBP C2D 2.16GHz OSX 10.4.11 is experiencing the same problem. After opening the notebook from sleep, the screen remains blank. (Tried PAKUR (pressing all keys until response)) but that was futile. Sometimes, I can hear the cooling fan and disk drive, as if the CPU is active. Closing the lid, I see the LED light turn on but stay on (not the pulsating sleep mode). I tried the above mentioned suggestion and I got a re-boot. Are you sure you don't mean leaving the cord connected? This is more than annoying, as I have had to reboot in front of a large audience the other day, and the machine took a while to recover. I'll try the password suggestion as well as the arrow keys, though I was pretty sure I pressed about every conceivable combination.

Trav

Hey Patti and Steve - I have the same problem you were having (LED won't pulsate although the screen is dark, acts like it's in sleep mode but I can't wake the machine up without restarting). Did you ever successfully resolve this?

Ingrid

I am having the exact same problem with my MBP. I've had the computer since Jan. 2007, but only last week did this become an issue. I'm going to Apple Store tomorrow to see if they can help.

darnitol

I read http://forums.macrumors.com/showthread.php?t=441089 on which one user complained that his problem was solved after removing the popular iStat Pro Dashboard Widget. I had iStat Pro installed. I liked it very much, but was embarrassed repeatedly when my supposedly awesome Macbook Pro wouldn't wake up without repeatedly closing the lid, letting it sleep, opening it, repeat until my login worked.

Nick

Just as an update, this is happening with reckless abandon on my Intel Core 2 Duo processor MBP with the latest and greatest Mac OS X Leopard (purchased January, 2008).

Before researching this issue my first action was the battery trick you mentioned, then the button reboot, changing of power settings, and I also stumbled upon the password entry technique (sometimes it took multiple times to work but it would occasionally do the trick). So none of this was necessarily new, but it did ease my mind that this isn't just my machine.

A couple of things I've noticed (or questions I pose to others) in trying to find a specific cause or solution to this annoying bug in what is otherwise the greatest computer I've ever owned:

1) Could turning off my Bluetooth device (i.e. wireless mouse) after putting to sleep disrupt the environment and trigger this issue? Could the same be true (environment change = problem) of unplugging the LAN connection or power cord?
*I've noticed at times when this is occurring that if I turn the mouse back on or re-establish the LAN or power connection and try again it will -sometimes- wake up.

2) Could removing the necessity for a password work?
*I'm not keen on this being a solution for obvious reasons.

Just my observations and questions... I'll be on the hunt for a real solution and will come back here and post if I find anything useful.

Kunal Choksi

I've got a 1 year old Macbook Pro 15" that is having the same problem.

None of the things I have tried above are working including holding the power button for 5-10 seconds. The lights shut off and then when I hold the power button again to turn it on, it's still in sleep mode. Keyboard won't engage and the screen is black.

Nothing seems to work.

It happened once before and it started again - but I'm not sure why.

Any help would be useful.

Thanks.

paulo

that solution didn't work for me. i've been reading alot on this issue, my MBP led light just blinks softly, I can hear the disc churn when I try to power up, but screen remains black. If this is logic board problem shouldn't it be even if under warranty or not Apple should replace it?

Lisa

Last month, my (early 2007) MBP 17 went to sleep and never woke up. It was the logic board. We had no problems getting the data transferred from the HD before shipping it to Apple. It took 3 weeks before Apple Care decided it was better to replace the MBP than to repair it. I bought a new MBP and then bought Apple Care for it; then Apple refunded the remaining months of Apple Care on the original machine. This new MBP has occasionally decided not to wake up after going to sleep, which scares the beezwax out of me, but I use time machine on a regular basis and hope for the best.
