Conservation for PowerBoo,

I reintalled my system (OS 8.1) on my PowerBook 3400 and now the conservation feature of the PowerBook Control Panel does not work.  (It worked fine before I did the clean install.)  I have tried various settings, but the computer never goes to sleep by itself.  The screen dims OK, but the hard drive takes much longer to spin down than it should.   Any ideas what would cause the computer not to sleep?

Ill assume thats a "no"...hehe ok have a read of http://til.info.apple.com/techinfo.nsf/artnum/n14449 ...about 2/3rds of the way down it will describe how to reset the powermanager on a 3400. The power manager handles things like...well...power..Battery consumption, sleep, etc. Sometimes it gets confused and needs resetting.

Didn't help.  I tried holding down the reset button for 20 seconds several times as described in the tech bulletin.  I recall, however, that when I had some work done on this machine about 6 months ago (it wouldn't boot up), the technician was using the same proceedure without any luck and ended up replacing the motherboard.  It could be that it has never worked since and I just didn't notice at the time.  Also, I note that my control strip module (Jeremy's Battery CSM) which is supposed to give me the historical estimate for the time left on the battery also does not work.  When I set it to the Apple estimate, it works fine.

Quackerback - Have you tried deleting the preferences in the system folder for the Control Panel you are using?  Or maybe since you did a clean install you can transfer the old control panel out of the previous system folder into the new one. That is unless you removed the previous system folder.  Can I ask the reason for the reinstall of the system?  It might help.

Quackerback - are these the steps you followed to reset the Power Manager?

Reset Power Manager:
1. Remove battery
2. Remove AC Adapter and unplug from the wall
3. Press and hold the reset button for ONE MINUTE
4. Plug AC adapter back into the wall oulet
5. plug the AC adapter into the powerbook
6. Test

Reset PRAM:
1. Unplug AC Adapter
2. Power on the computer by pressing the power key
3. IMMEDIATELY hold down the Open Apple (Command) key + Option key + P + R
4. Continue to hold these keys down until you hear the computer chime more than once.  I sometimes make it chimes four times.
5. Press the reset button once.  Wait for a moment it should start up.
6. If the Powerbook does not power up, turn it on by pressing the Power key.
7. After the computer starts shut it down doing Special Shutdown
8. Plug in the Ac Adapter.  If the computer stays shutdown then you did it right.  If not, then reset the power manager, as I showed above.

I know this is a pain but I hope it helps.

I held the reset button down for 30 seconds.  The tech article said 10 - 20.  I think I did the rest, but will try again.  I reinstalled the system because I had my hard drive divided into 4 partitions and decided to reduce that to two.  I could have just reinstalled the backup but thought it might be wiser to start from scratch as I would crash several times a week, maybe even a couple of times a day.

I did everything cdeagle suggested and it still won't sleep on it's own.  I also ran TechTool Pro and repaired a number of files.  I reset the PowerBook control strip to the minimum setting.  Nothing works.  I shouldn't say nothing--the screen dims right on schedule but it won't go to sleep.  Anyone know a good lullaby?

Okay, can you put the system to sleep by going to Special then Sleep?  Have you tried loading only Mac OS 8.1 Extensions using the Extension Mamanger?  Have you tried rebuilding the Desktop (hold Option + Command {open Apple} down before the desktop loads.  Keep it held down until the system asks if you want o rebuild the desktop).  When you say you have meesed with the settings in the control panel which control panel are you messing with?  Energy settings, are you using the advanced settings?

"Rock-a-bye baby on the treetop,when the winds blow the cradle will rock...."   the best one I know of. :o) hee hee

Just curious, did you ZAP the PRAM as well? I believe some of these settings are stored there?

If this does not do it, I can ask the programmer on the power manaer for the 3400 and see what she can tell me.

Time for a CLEAN system re-install followed by troubleshooting.

1) Open CD-ROM drive and insert Mac OS 8.1 install CD
2) Reboot, zapping memory management and PRAM while you're at it
3) Reboot Mac, Hold the 'C' key down during the reboot. The Mac should boot off the install CD.
4) Double-click on "Mac OS Install"
5) Click "Continue" at the Welcome screen
6) On the select disk screen check the "Perform Clean Install" box after selecting your disk. The clean install will rename and deactivate your existing system folder "Old System Folder" and install a new one.
7) Proceed the rest of the way through the install, let it pick the right install choice for you, don't do custom
8) Reboot
9) Test Power Management
NOTE: If it doens't work at this point it is time to talk to a service person as it is probably hardware.
10) Now you can start dragging items from your old system folder that you need in the new one (Extensions, Control Panels, Preferences, etc).
Be careful what you drag over, and reboot and re-test after each few drags. If the problem re-occurs then one of the pieces you just dragged is the problem, remove it.
Be sure back up any pieces of the new system if you are dragging the same filename from the old, after all, that could be the problem piece.

Good Luck!
Scott

Turns out that cdeagle30 had the answer.  Switching to OS8.1 only did the trick so evidently I have a system conflict.  Time to put Conflict Catcher to work!  So if cdeagle responds, I'll give him/her the points.

Ignore my previous comment.  I just figured out how to give cdeagle30 the points.  Thanks!

Quackerback,

I am glad that this helped you.  I was beginning to wonder what had happened.  Had not heard from you in a while.  When you figure out which extnesion or control panel is causing the problem let us know.  It might help other in the long run.  Thank you for the points.
