Put to Sleep and Don't wake up when i open my macbook pro
Hello,
i have a Macbook pro 17' (2,33ghz) using leopard 10.5.2 with all the latest update.
Everytime i put my computer to sleep for more than 10 minutes (random time), when i try to wake up nothing happen, i hear a strange noise of the HD for about 2 seconds and the screen stay Black.
When i close the computer again, the light stay On, when i open the computer again nothing happen, the screen is black, no buttons works, nothing happen.
So i have to press the Power button for a few seconds and then turn on my Mac again.
this happen to me every day !
i try:
Remove the charger = Same Problem
With the charger = Same Problem
With Apple Bluetooth mouse = Same Problem
Without Apple Bluetooth mouse = Same Problem
With External HD = Same Problem
Without External HD = Same Problem
when i try to wake up the Mac, I wait for more than 10 minutes and nothing happen.
i see the Log's and i can't see antything Wrong.
this is not the first time i have this problem
in 10.4.8 i have the problem, when i update to 10.4.9 "fix the problem" until 10.5.2
i have the AppleCare.
i dont know if this is a Hardware or Software problem and if the guarantee cover this?
thinkin that this could be a HD problem so i check in the disk utility and everyting is OK.
Thanks!
Well. in my searching i find an """"Answer"""
Some body was talking about that the new's Mac have something called "Safe Sleep" so when someone sleep the Mac the Information of the Ram make a copy in the HD this can take for 30 seconds to a minute. In this time, if you move the mac or do something else, generate a error and corrupt the Information of the ram and the Mac stop working.
Say that to remove this "Safe Sleep" have to open the terminal and:
The Unix command to disable SafeSleep is:
sudo pmset -a hibernatemode 0
To re-enable SafeSleep, the command is:
sudo pmset -a hibernatemode 3
Maybe Apple going to Fix this in future Updates.
Sorry for my English !

Whenever I open up my Macbook Pro, Firefix is unresponsive. I can see all of my tabs, but nothing (except the top pull-down menus) are clickable. If I wait a few minutes it seems to work again, but I usually have to force quit. Anyone else have this problem?
Firefox uses plugin-container.exe to run Flash and other plugins. The theory is that if the plugin were to crash, it would not crash all your tabs, just any active plugins. Are you getting a message that a plugin crashed?
If I understand the problem correctly, Firefox is hanging or freezing when trying to open a link, and you are exiting Firefox, after which it won't start up again until you kill firefox.exe in the Task Manager.
Have you noticed any pattern to when Firefox freezes or stalls?
How are you exiting Firefox (for example, from the menu vs. red X button vs. Ctrl+Alt+Delete)?
In case you haven't seen it, this article might be useful: [[Firefox hangs or is not responding - How to fix]]. -
My computer sleeps and doesn't wake up
Battery might have run down, but even when plugged into AC, computer won't start up. It appears to be sleeping, but won't wake up even though I'm giving it juice.
I have the same computer, and probably the same problem. I never had any problem with sleeping and waking until one day when I closed and then opened and then closed the computer lid all in about a second. From then on, if I ever did a sleep by either closing the lid or selecting "sleep" from the Apple pull-down menu, the chance that it would wake up was about 1 in 10. The rest of the time, the disk would spin up but the screen was dark. There was nothing I could do except hold down the power button for 5 seconds and then restart. This was exceedingly annoying, as quickly sleeping the computer with all of my applications up is one of the best things about the laptop.
I got on the Apple phone support line and they told me to do an "archive and install" with my original disks, but it didn't help, so the expert I finally got on the line said that it was probably a bad switch in my lid and to take it into my nearest Apple service centre. This I was loathe to do, because the most convenient one is run by the biggest bunch of jerks, so I put up with having to "Shut Down..." from the Apple menu and then restarting for a few months until I had time to take it to another place which is less convenient.
However, recently I bought Leopard and did an install. Presto, my problem disappeared! It looked like a file was corrupted and was not fixed with "archive and install", but was with a new OS. I wish I knew what file that was.
I should say that I also disabled the "safe sleep" option, which was mentioned as a potential problem when I was researching earlier. I greatly prefer having no safe sleep, because sleep now takes 2 seconds instead of almost a minute. -
My mac iMac 27 2010 vintage goes to sleep and won't wake up till I hold the on off power button....Then I have to restart as it is locked up....This it intermittent..
Help Please
JimOps I replied to myself in error.....
Tom:
I performed the steps indicated but this morning when I clicked the mouse and hit the space key and clicked the track pad again as before nothing happens.
I hold the power button for a few seconds and the screen fills as if the computer was normally awakened but it is locked up.
Then I have to shut it down with the power button and then power it up as a reboot.
Not good...SMC reset didn't work....Throughout the day yesterday I put the computer to sleep and woke it up normally. It seems to be a overnight problem.
Am I going to have to shut it down everynight?

Why does updating virus definitions on microsoft security essentials make my macbook go to sleep and hard to wake it up from its sleep state? does this happen to anyone else? its really bugging me.
Just you probably, having used it for years since its beta days.
don't run more than one malware suite/programs. it is possible to use some as long as they aren't running.
I'd look elsewhere for why. -
what is an smpt password? I have problems sending photos using the stamp at the bottom because it asks for some smpt password and I have no clue to find out what it is, how to set one of find one if I somehow put one in and don't know what it it.
It's the password for your outgoing mail in your Mail account. You need to set it up in your Preferences.

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem
Hi I've been following this thread (along with a different one on the same topic). I've been having the same problem with my ibook. I can add that I have no problem with startup. It's just that the screen "goes to sleep" unexpectedly and may operate normally for a few minutes or a few hours at most. Opening and closing the lid or restarting seems to cause it to awaken but then usually for just a few seconds or minutes. If it is connected to another video display that display continues functioning fine even though the computer screen is blank. In addition the desktop is there and visible faintly or if totally blank can be backlit through the apple logo and can be read. I've had my logic board replaced twice under the extended warranty and assumed it was that but now I'm thinking of the reed switch. Apple refuses to consider any further work under warranty as the last repair was in Jan, 06 and they claim only a 90 parts warranty and the machine is from 03. Any thoughts before I cut the wires? I have reset the pmu, run cocktail and disk utility. Other than the sleep issue the machine works fine. thanks Ronda or anyone else who has any ideas... Dave

I just tried to wake up my 4 year-old MacBook Pro after perhaps an hour of inactivity, and it just 'pinwheels' and won't restart. HELP!!!!!!!!!
Semi-experienced user - Western New York.
System was operating nominally until I opened it from 'sleep' mode after ~1 hour of inactivity.
No idea what's going on. I had just installed a Flash Player update [not an atypical occurrence] at ~6:00 PM this evening, but used the system without incident after that. Re-Start attempt does not appear to succeed, the circular pre-OS icon never clears and displays the authorization screen.
Anyone with an idea how to help would be greatly appreciated. We have so much personal and business data on this machine!!!
Thanks!
Jim F.Press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly to restart.
The fact that you're worried about the data implies that you have no backups, or that you don't have confidence in your backups. Your first priority must be to back up all the data you intend to keep. Ask if you need guidance. -
Downloaded music apps o.k. Says login failed when I put in user and password. No trouble when getting any other apps.
Sounds like you may have deleted something you shouldn't have. Boot to an OS X DVD or a bootable backup, and using Disk Utility, do a repair disk, and while there repair permissions. Disconnect any peripherals, and reboot. If you get the same startup behavior, do a safe boot, by holding the shift key down when booting. If that works, try a normal boot. If neither step helps, you may need to relaod your operating system.

hello..i have the macbook pro and i had a password when it opens and when i have updated the software when i delete something it asks me every time to put my password ;/ how do i delete my password or just correct a setting for it?
You may need to rebuild permissions on your user account. To do this,boot to your Recovery partition (holding down the Command and R keys while booting) and open Terminal from the Utilities menu. In Terminal, type: ‘resetpassword’ (without the ’s), hit return, and select the admin user. You are not going to reset your password. Click on the icon for your Macs hard drive at the top. From the drop down below it select the user account which is having issues. At the bottom of the window, you'll see an area labeled Restore Home Directory Permissions and ACLs. Click the reset button there. The process takes a few minutes. When complete, restart.
