MacBook wake-up problem?

[bill4588]

My macbook has always done this but I'd like to know if it's "normal." Say I'm using my macbook browsing macrumors.com and then I'm done so I close the lid. I open it a couple seconds later because I forgot to check something before I closed it shut - but now I have to wait 15 -20 seconds for it to turn back on. Why? No matter what button I press the computer refuses to turn back on for a good bit. Is there a way to fix this?

When you put your macbook to sleep, the first thing it does is copy the contents of the memory to the harddrive, then go to sleep. This is so that if power is completely lost (say it's running just on the battery, and the battery is unplugged, or runs out of juice) your computer can still restart without a problem when power is restored. It's a deep sleep.

The problem is that if you try to wake it back up while this is happening, it won't wake up--at least until it's done, possibly not until it's done and you tell it to wake up. I find the best thing to do in these cases, is to wait 15-20 seconds and press the return key. If nothing happens, wait another 15-20 and press it again.

There is a way to turn off the deep sleep feature, that would mean the macbook went right to sleep and should be able to wake right back up again, but if it ever lost power while it was asleep, any unsaved work would be lost.

I don't think you can, nor can I see why you would want to. You do this so much that it's actually a problem?

Short answer:

In a terminal type:

sudo pmset -a hibernatemode 0

and enter your password when prompted.

sleep problem seems to be solved with software

Bought a macbook pro two weeks ago. After installing the system the macbook pro did go to sleep but refused to wake up. One could only see a flash and hear the fans. After resetting, giving it back to the repairshop to see if there were hardwaresources I got the macbook pro back with the anouncement: 'nothing wrong, havenot seen a thing. Well, immediately after using the macbook pro the problem re-appeared. It wasnot a resetproblem. I removed the hibernate-disk, used the terminal, etc. to no avail.

Finally I sought a software solution and found the preferencepane: iLid, http://www.ego-systems.com, and the terminalcommand Wakeassist, http://www.dssw.co.uk. ILid forces the macbook pro to wake up when you open to lid of your laptop. Well, after installing the macbook pro promptly starts and doesnot cling to its sleep, or simply freezes. Seems that apple botched up the programming. So, I hope this will help someone. It did help.. If not I'll be back to post again. And scream the hell down to that miserable computermaker who is making a mess..

Thanks, interesting re: software.

Took mine in for repair for same problem, not waking from sleep (screen not waking really, keyboard is active but that's it) is getting a new logic board in repair at the moment as the repair centre couldn't identify the fault either, although one of my firewire ports wasn't working (3 month old SR MBP)

Tried all the suggested fixes, including changing sleep mode, none helped.
