Workaround for TiBook wake from sleep glitch
Aug 15, '02 09:28:07AM • Contributed by: William McCallum
I have had an intermittent problem with my Titanium powerbook not waking properly from sleep: the hard drive wakes up, but not the screen. I don't know what causes it, but I seem to have discovered a workaround: if this happens, close the cover, wait till the pulsing light at the hinge indicates the machine has gone back to sleep, open it up again, and hit the spacebar. This has worked for me twice so far (it doesn't happen very often, so I haven't had the opportunity to test it more than that).

Same problem with Pismo
I have also had this problem with my Pismo G3 PowerBook. It has happened a number of times, and the method you described seems to do nothing. I always have to hold down the power button and restart it the hard way. Has anyone found a workaround for that?
Fix on Wallstreet
I had this several times on a G3 Series Wallstreet Powerbook. I got it fixed by booting into Mac OS 9, putting the system to sleep there and waking it up again.

Fix on Wallstreet
Thanks for the tip on booting up in OS 9, then go to sleep and awake. For some reason ?????? it worked and now I can put it to sleep in OS X and awake it with the screen bright as ever.
brightness button
On my Pismo sometimes this would happen. I tried the power manager reset
brightness button
Just a quick note: using a dark screen saver does nothing to prolong the life of an LCD screen. Unlike a CRT the individual pixels of an LCD screen are actually just color filters in front of a backlight. So when a pixel is black it just blocks all the light from the backlight. The backlight is what usually goes bad in an LCD, so the less it is on the better.
Same here
I've observed the same behaviour often on my iBook 500 2*USB.
sleep problems w/ Lombard too!
ditto!
Not only powerbooks
I have the same problem with my PowerMac G4 sometimes. The method described in the hint works for me every time.
Not only powerbooks
Same here, my G4/400 does this periodically. I can even get itunes started with my F-key combo and start the visuals and the monitor still doesn't kick on.
Not only powerbooks
Whats the secret on the G4? My G4/400 does this about once a week - but I hav eno brightness F-keys on my keyboard - any other technique?
Here's how to reproduce it, at least on my 667 DVI
This seems like the same thing that happens to my titanium once in a while. If I close the lid to make it go to sleep and then open it before the pulsating light has had a chance to come on, it's sitting there with a black screen but with the HD/fans still running. The only solution I've found so far is to hold the powerbutton for a while to turn it off and on again. Will try your tips tonight and report back.
Discovery.
I also ran into this problem on my TiPB.
Virtual PC
Earlier versions of Virtual PC caused wonky sleep/wake behavior on my TiBook, though I don't remember the exact details. It took me a while to figure out because the problem was so intermittent and unexpected—I don't have many uses for Windows apps on my laptop, so I would attribute it to knocking it around in my backpack. Ever since upgrading to the latest VPC version (5.0.4?), I have not had sleep/wake problems. How many of you were using VPC when this happened? Or perhaps some other application is at fault?
Another sleep bug?
I've got a pretty infuriating problem with my Powerbook. It's only every so often but it's incredibly frustrating. I often close the display and have the computer go to sleep if I'm not going to be using it for awhile. When I want it to come out of sleep, I'll pull the lid open, the computer will come up and ask me to type a password to unlock the computer from the screen saver. I'll type in my password, hit the enter button, and it'll unlock the computer for a second or two before the screen saver reactivates and asks me to type in the password again. It will loop like this until finally I have to press and hold the power button down until it shuts off. This has happened in 10.1.5 and I would have hoped that wiping the hard drive and doing a clean install of Jaguar off of my friends new iMac computer (I have a copy on the way from Apple :) but wanted a chance to install it), but Jaguar does it too. Any ideas?
Another sleep bug?
Any chance you have the caps lock down?

I've had this same problem, but it is usually caused by the laptop closing, and then getting bumped open and closed without getting to fully wake up or sleep. Since this is only an issue when I'm transporting it from home/work/travel, it only happens when it's on battery power, and therefore one solution is to "disable wake from sleep when the lid is opened, when battery power is used". You can do this with:
TiBook Sleep Problem Workaround
My laptop wakes up with a black screen if I disconnect a second monitor aftrer it has gone to sleep by closing the lid. Adding the second monitor back only produces two blue screens. Hard reboot is the only way out. I had hoped that OSX 10.2.1 would solve this problem but it has not. However this workaround continues to work.

Actually, my comment was supposed to apply to the post before this one.
An Easy solution in 10.2
I'm not sure when this became available but, I know it works in 10.2
An Easy solution in 10.2
On my original TiBook, at least, Command-F2 (brightness up) does detect displays from the keyboard
An Easy solution in 10.2
another easy way to Detect Displays from the desktop is to turn on the "Show displays in menu bar" option in the display control panel -- don't know why this isn't turned on by default, but i change resolutions and (because of my ti-400's lousy graphics card) color depth without hastle via the menu icon. |
