Sep 16, 2015 8:41 AM in response to Klaus1by kenlesser,Klaus, this is great because I also have an old Power Mac G5 desktop that will at some time need a PMU reset. Now I know how to do that on this big boy.
Might you also be able to refer me to how to do the PMU reset on my laptop, the PowerBook G4 Aluminum, 1.25 GHz model? Thank you!
Also, a fantastic feline foto!
Gratefully,
Ken

Our good pal Klaus barely missed it with his 2nd link - 5 article numbers and one Generation (G5)
This one may be it (G4 PBs) > Resetting PowerBook and iBook Power Management Unit (PMU) - Apple Support <https://support.apple.com/en-us/HT1431>
good luck

I simply used Google Site search for the OP's first sentence (copy/paste PLUS)
[ How to reset PMU on powerbook G4a, 15", 1.25 GHz.; model: PowerBook5,2. site:support.apple.com ]
Internal search is not my cuppa tea. ;-(

PS: I have an ongoing Battery issue - turns out, I had been resetting PMU in my Pismo ALL WRONG!! Didn't solve it though (I don't think - maybe time will tell) [x-ed fingers]

Sep 22, 2015 2:13 PM in response to ChitlinsCCby kenlesser,Hello, ChitlinsCC,
Thanks for supporting us olde Apple folks. I am now so close to lifting my keyboard and doing the PMU process. The link you kindly provided explained:
Disengage the two keyboard latches located between the Esc and F1 keys, and the F11 and F12 keys. (You may also need to disengage the keyboard locking screw located between the F5 and F6 keys.)
I've looked at the two places to figure out how to disengage the two latches, but at this time am still puzzled about what to look for and how to do the disengage process without any collateral damage. Any further assistance would be appreciated.
Gratefully,
Ken

If you have found *where* these are, feel with your fingernail for a tiny 'lip' to slide the latch (mine on my Pismo is 'toward the display' edge) toward you gently.
