A1278 13" MacBook Pro Waking Issue

MacBook Pro 13.3" - Early 2010

A1278

2.66 Ghz

16 GB RAM

2 TB Hard Drive (249.11 GB used)

10.9.5 (because I like Mavericks, we're happy together)

The issue is that the MacBook Pro won't wake up if I have closed the lid. I have to reset SMC every time (or hold down the power button until it shuts down) and restart it to get it up and going. (I have also reset the NVRAM, only because I was trying everything. No change.) Resetting the SMC is ineffective, as the issue returns every time I close the lid. Disk Utility only shows the typical Safari permissions that need changing, as they always have. Rebooting in Safe Mode doesn't prevent the issue from happening.

I always leave my MBP plugged in, because I do all my work right by an outlet, so I have the energy power adapter settings to never sleep for both display and computer. I have "put hard drive to sleep" unchecked. I do have "wake for network access" checked. My battery settings are set to 3 hours (although I never unplug it) and again, "put hard drive to sleep" is unchecked.

I recently disabled hibernation because I suspected it might be stuck in safe sleep mode, but it had no effect. I also made sure that lidwake is set to 1. In fact, here is a paste from Terminal:

Battery Power -1

AC Power -1*

Currently in use:

womp 1

halfdim 1

sms 1

hibernatefile /var/vm/sleepimage

networkoversleep 0

disksleep 0

sleep 0

hibernatemode 0

ttyskeepawake 1

displaysleep 0

acwake 0

lidwake 1

(I'm not sure what the -1 next to battery power and AC power mean; maybe someone could educate me?)

There are no magnets in my work space, so I don't suspect that sort of interference. If I put the laptop to sleep by selecting that option from the apple menu, I can wake the computer up. It really does seem to only fail to wake when I have closed the lid.

I would appreciate any insight (short of calling me names, ha)! Thanks so much.

Crickets in here...

Okay, for anyone looking, I may have figured it out (for my unique situation). Not long before all this began, I had replaced my logic board. On a hunch, I opened up my MBP today, removed the board, checked to make sure the LVDS cable was seated securely and not in a bind, as well as the DC inboard cable underneath. I suspect that this was my issue because since I put it all back together, I've gone all day without incident (when it had begun to happen once or twice an hour). All this to say, if you're experiencing the MBP screen going black (or bright orange or hot pink) all at once and having to reset the PRAM several times a day or the MBP refusing to wake up from sleep, re-seat your cables. Maybe you'll get lucky. Not very profound, but there it is.

Well... it's almost November. I think I've waited long enough not to be accused of bumping my thread. For anyone out there who does a search about this issue and ends up here, looking for answers... sorry. Nothing to see here. :-(

Just reinstalled the OS and reset the PRAM. Closed the MacBook to run to town and when I came back, same thing: wouldn't wake up. Of course, some may suggest that I never close the lid... but shouldn't I be able to if I wish?

Very frustrating.

For anyone who's interested, I mulled this over and over and the realization came to me that the sleep light indicator only occasionally pulsates but, more often than not, it is steady. This made me wonder what would happen if I manually put the laptop to sleep through the menu, wait until the light begins to pulsate and only then, close the lid. It does take the light a full minute or two to finally pulsate. I tried this last night. This morning, the laptop woke up when I opened the lid. Apparently, simply closing the lid does not cause the MacBook to sleep. But it should, right? Is this a setting I can address? I intend to put my Terminal pmset changes back to default, but are there ideal System Preferences settings that might help closing the lid to immediately put the laptop to sleep? (It is apparent that closing the lid first does not allow the sleep light indicator to pulsate and is preventing the laptop from really sleeping. When I reopen it, I have a black display and have to resort to the resets and power-ups I mentioned earlier.) Thank you.
