Can't find POWERin the system profiler!

Question

Can't find POWERin the system profiler!

Iseemto be having some sudden battery issues and in reading some of theposts they recommend going to the system profiler and looking at the POWER reading...but my system profiler does not show POWER as a heading. I did: about this mac>more info>hardware, but there just ain't no power listed there! I chose extended report....nothing. I downloaded a couple fo freeware apps that were recommended in the discussions and find that my battery has cycled 342 times, and that the temperature on my laptop is just dandy. But suddently, my pb is not charging as it should; it is very slow to recharge and doesn't seem to hold it through sleep (when I close the case). Is it possible it is not sleeping when I close it? Well, any help would be appreciated, as always!

How bizarre. Anyway, try deleting the file …

/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

… and restarting to see if things appear.

Have you tried the usual resets…

PRAM and NVRAM

PMU

Ok this is starting to freak me out a little! I reset the PRAM and NVRAM following the instructions, and then reset the Power Manager. I had to reset the date and time so I know I affected something! Still no POWER heading in the system profiler. So I thought maybe after doing those things I should once again trash the preferences as above...now that file doesn't exist at all!! Shouldn't it rebuild as soon as I restart the computer?
By the way, I reset the PMU by turning off the computer, removing the battery and power supply, then holding down the start button for 5 seconds, then replacing the battery and booting up. That's correct, yes?
Thanks,
Debbie

Yes it should!!

That's correct, yes?

Not all PowerBooks do this quite the same… which model/CPU speed do you have?

EDIT : With regards to the date and time being reset, this is normal and does show that the PRAM was reset correctly. Don't be freaked by this bit.

Hi Debbie,

Maybe someone with a better memory than me can clarify this, but I think the Power heading you're being pointed to may be a function of Tiger and not Panther.

Hi,
Oh

Well that might explain some of it anyway! I have a G4, by the way, 15", 1.67 GHz.
Thanks for your help!

While I'm not sure this is the case as I do recall, I have the same problem as you Joe 😉, power settings being shown under Mac OS X 10.3. As you say, it may not be in the same way.

Having said that, there still is some weirdness going on as the power management settings weren't recreated as I would expect.
