Mac Os X Lion Crashes after resuming from Sleep

Hi Everybody, i'm experiencing an issue on my 13'' MBP Early 2011 (i5 processor, 4GB RAM, 750GB HD SATA). My MBP often got stuc after i resume from my monitor sleep. I'll explain it in a better way: After i resume from sleep, there's at first a black screen in which the mouse can move, after that the mouse becmes the classic loading wheel and it freezes copletely, remaining in this situation. I thought it was a screensaver compatibility issue, but the problem stand still after i uninstalled screensaver and deactivate the screensaver options. I think it's a problem with Lion with the HD, but i have no evidence of it. Can Anyone help?


Thank you in advance,


Daniele.

MacBook Pro, Mac OS X (10.7)

I have this issue, but with a twist: my boot partition (as opposed to my Lion recovery partition) is corrupted to the point that it won't boot. I just left the Apple store, where the suggested solution was to replace my SSD. I can see my boot partition from inside the Terminal and back up to an external drive; still, this is pretty unacceptible. The MBA is literally just a few weeks old, and it slept/woke just fine under Snow Leopard.


I'm considering deleting the directory where OS X writes sessions from RAM but I don't know where it is. Any one have any ideas?

To be more specific with my issue: (Late 2010 13 MBP)


If I select > restart and press the option key to dual boot (or whatever) I get a grey screen with a spinning circle that does not go away. The power light goes out on my MBP, the circle spins, but nothing else happens. Then I have to hard reboot.


Additionally since enabling FileVault 2 my recovery partition has dissappeared. I sincerely hope that my Time Capsule which looks like its working is really backing my info up just in case something happens.


I'm a bit skeptical right now. This feels like Vista to me.

Whenever someone comes to me with crashing and freezing on waking up I look at 3 things and typically in this order:


(1) Hard drive - usually if it is the hard drive SMART has already given a warning if the drive is actually failing or running Disk Utility reveals problems - often problems that cannot be fixed. Also, when the crashes are related to the hard drive there may actuallly be nothing wrong with the drive and a simple erase and reinstall will fix it.


(2) Software issues - the old trick of creating a new account and logging into it to see if the problem is in your account or global helps. Looking in console to see if there's an error message logged just before the crash can be instructive - or not. Often the crash occurs before an error is logged. Sometimes reinstalling the OS is the solution - that's where having a FireWire hard drive is helpful. I can just boot with it and see if the computer still crashes on waking. If not I know to reinstall the OS.


(3) RAM - marginal and faulty RAM can be the culprit in many cases. The frustrating thing about RAM is that RAM tests seldom give false positives, if the test says you have bad RAM, you do. Unfortunately when the test reveals nothing wrong the RAM might still be defective, just not enough for the test to catch.



However, past history has led me to put RAM at the top of the list after an OS upgrade. Marginal RAM has been the culprit of many crash on wake problems with previous OS upgrades. I especially recall Leopard and Snow Leopard being affected - at the shop where I sometimes work we did a lot of RAM warranty replacements after those two upgrades. And here at the support forum we saw lots of people complaining of crash on wake problems coming back and saying, "Yep, got my RAM replaced and all is well." So if any of you are like me and upgraded your RAM, if you have the original RAM sitting around swap it in and see if the crashes stop.

If you have VMWare Fusion installed, try re-installing. This took care of the problem for me. I noticed messages during the boot [I had many occasions to watch them] that mentioned VMWare and I figured that if it was deep enough in the OS to be mentioned during boot that maybe it was worth a try. The re-install doesn't take long and doesn't affect any existing VMs (naturally you must stop VMWare and I shut down the actual VM) so if I am competely off base your investment is not high.

Hmm, I think I have a new data point. For me, the crash/hang seems to be related to hooking up an external display.


My typical setup has my MBA hooked up to a 27" Dell U2771 via a Mini-DP -> DP cable. Works great. I operate it with the lid closed.

At night, I disconnect power, video and USB and take the laptop home, maybe work a bit in the evening. In the morning I connect all three cables back up, hit the keyboard and hopefully start work again. This always worked fine in the SL days.


After installing Lion, this routine results in a hung/crashed computer. No response, no display, nothing.


Today I didn't hook everything up right away, I instead just opened the lid. To my suprise, the Mac came back up fine, showing the password page (lock screen).


I then hooked up the monitor and everything crashed. My guess is there's some problem with switching to external displays after coming out of sleep, and/or the lock screen.


Tomorrow I'll try hooking up the monitor after logging in to see if that helps.
