Whenever I wake I get security errors.

Okay I think I have found a fix to some people who get a black screen or nothing on wake. This is only for people with Airport. What I did was use original EFI strings. Then Sleep WORKED! But I installed an Airport Card and would give me a black screen. So now what I tried to do was turn off Airport and put the PC on Sleep. And It fired back up. So hopefully this works for you guys.

Ironically... I have the exact same problem, but on my real Mac (a MacBook Pro)

I actually just reinstalled the operating system last week, but for the last year I've been in the habit of never putting it to sleep, so I haven't tried yet. Maybe it's fixed now, I'll try soon. This is running Leopard, however.

Mine doesn't even go to sleep, the hard drives turn off but my video card's fan goes to 100% and the screen goes black and it just stays like that.

I too am having a wake up issue. I'm running a retail 10.5.5 install. The notebook will wake from sleep perhaps 3 in 20 times. The only pattern I have been able to observe is that when it fails to work from sleep the error console says:



These errors do not show up when the system correctly wakes. Disabling wireless before sleeping does not help at all. The strange thing is physically removing the wireless card does not fix the problem but only removes the error messages. System specs in profile.

I am running an Acer Aspire 5610 that has 10.5.4 and it went to sleep, now it will not wake using either the original drive or the Vista one. Every time on start it looks like everything is working and then nothing happens to the LCD or the external monitor. Any suggestions?

[[color="#9932CC"][/color][size="5"][/size]Hay is there anyone who has had a problem with the apple update, if i update the software it wont boot osx back it just scrolls the screen and reboots but it seems as thogh you have to use the software on the osx 86 disc any thoughts other then a sound driver problem my e machine pentium d is working great

I found this page which explains how to change sleep mode of Leopard. Might be useful for some people?

Terminal command to check your current mode -

Then to change modes you can type this: (Example of setting it to mode 3)

List of modes available -

0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.
1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.
3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.
5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences —> Security).
7 - This is the same as mode 3, but it’s for those using secure virtual memory.
