Recently I noticed that my Pismo, when sleeping and not plugged in, seems to suffer some pretty serious battery drain.

If it slept 5 days it'd pretty much drain a fully charged battery.

Any thoughts? Is the battery bad, or maybe it's a Power Manager thing? How do you actually reset the power manager? Is it just a "paper clip" hard reset, followed by a normal reboot 30 seconds or so later?
thanks!

To reset your power manager, turn off your computer and remove all sources of power (power adapter and battery) from it. Leave it like this for about ten minutes (or more, to be safe).

Personally, I think it's a bad battery...

Do you have anything plugged into it while it's sleeping? USB or otherwise?

nothing plugged in now. at one point, around the time i noticed the drain, there were externally powered speakers plugged in.

now, though, nothing. still drains. do you think the speakers may have impacted the battery?

i'll try resetting the power manager and see what happens.

thanks!

The speakers could possibly have impacted the battery life.

Are the speakers powered by the PowerBook, or do they have an external power source?

This could very well have been your problem.

They are externally powered...

[seanyepez]

Then it's not the problem.

If they're externally powered they wouldn't use much power, or any at all, even.

I think it's your battery.

Sean, the method you mentioned is NOT a reliable way of resetting the Power Manager.

Instead, go to the Apple Tech Info Library (http://til.info.apple.com) and look for the proper method (see http://til.info.apple.com/techinfo.nsf/artnum/n14449); your method largely ignores the rechargeable PRAM battery built into every Apple notebook.

Hey tooki - thanks. I didin't know of another way to reset the power manager.

I'll check out the TIL, again, thank you!
