Hi all, I have been hunting around the various groups and forum's for a solution to my problem with an ibook, so I am hoping someone here will be able to assist. I have a g3 Ibook 900mhz 384MB Machine running a recent upgrade to Tiger. ( I cant rememebr if this problem happened with the change over, but I vaguely think it did)
I just bought a second battery for traveling e.t.c and both batteries hold about 4hrs charge. (big smile) However I have a problem when I put the book to sleep (sad frown) When I close the lid the ibook goes into sleep mode, but for some reason it completely drains the battery. One all occasions the battery has been almost fully charged before I closed the lid, and upon waking up my ibook I have noticed a battery drain. My research on the fourms has not yet found someone with the same problem so I have been racking my brain trying to find out why this is the case. is it something to do with: A/. My airport connection? I have a wireless connection at home, is it picking this signal up and turning the HDD back on? B/.384MB RAM, is this enough to temporarily store tiger's data? C/. A bug in the 900mhz Ibook model?
If someone can please help it would be great, I LOVE the instant sleep and wake of my book, and I dont want to have to keep shutting my system down when I am planning on leaving the item unused for a few hours.

No.
B/.384MB RAM, is this enough to temporarily store tiger's data?
If 384MB is enough for your operational needs, it's enough for sleep. If it were a problem, you'd notice it while running first.
C/. A bug in the 900mhz Ibook model?
Not one that I am aware of. I don't own that model, however so I'm not as familiar with it as I could be.

Two questions:
- When you put the machine to sleep, what exactly happens when it goes into sleep mode? (drives shut down?, LED pulses?, etc.)
- How long do you leave the machine asleep for?
Sleep mode drains approximately 10% of the battery per day, so 10-14 days is about all you get off of a battery.

One other possibility:
Go to System Preferences -> Energy Saver -> Options (with 'Settings for "Battery Power"' selected) and make certain that the Wake Options are both turned off.

John, Thsnkf for your reply. It happened again last night. I put it to sleep via the menu to be sure it was actually initiating, the machine was at about 40% battery power, and now 6hrs later...completely drained. In answer to your question, when I put it to sleep, the drives shut down and the LED pulses as it does on my Imac G5.I usually put the machine to sleep overnight, only to find it completely dead in the morning.

It needs the PMU reset. Do a search at Apple Support for "PMU reset" and follow the directions for your model.

I guess I spoke too soon, I woke to a dead laptop this morning. What next???
D.-
Did you fully charge the battery after doing the PMU reset? If not, you may have started with a nearly-discharged battery that appeared to be fully charged because of the previous PMU problem. It needs to fully charge to calibrate the battery monitor circuit.
I suggest you repeat the PMU reset, and let the battery charge overnight before putting it to sleep again.
