Powerbook G4 and Water... and a broken heart
Sorry if this is too long...
I already got a new one (MacBookPro) but can't get over the loss, or give up. So I look for advice, as how to continue from where I'm stuck.
This is the situation.
Water got into my 1GHz Powerbook G4 (aluminum) while it was *sleeping* (on, in other words). And it quit. I took it apart, opened it up and dried it out over some time (days...). And *put* it together while still open. And it did boot (only without the battery, though) So here is the situation at this state: It comes to life, screen and all, but it makes these *sounds* ( on and off...) like when you hit the wrong keys...and the *eject disk* icon pops up on the screen now and then. Also other F-key functions *wave in and out* ghostlike: the F11 function...) I so disconnected the keyboard (while the Mac was on) and connected an external USB/Apple keyboard. No change. I then managed to get up an onscreen keyboard, since the MOUSE PAD still works. The on screen keyboard shows several keys *engaged* : 7, u, k, , (comma) ( a strange diagonal pattern?) . F9 and F10 are also *grey*, but can be disengaged...
My idea was to reset the parameters. Unfortunately, this is done by a keyboard combination on this machine... which is where I am stuck. Isn't there a hardware switch SOMEwhere on the Motherboard???
That said, I don't know if I'm on a probable path at all, thinking that some key-command needs to be *undone*; I'm no expert, other than that I dare to open the box...and use MY common sense. I know I will need anew battery...
And I'd so like to have it work again... I do have all my data (drive works fine) and a nice new mac...still...there is love left.
Any advice to had?

I think shutting down, and then holding down the Power button with the battery out until it either makes a noise or flashes the LED might reset the motherboard on this model. Look at the Support tab at Apple.com keyword CUDA or PMU or Power Management Unit.
Wow, that is a weird situation - even the external keyboard gives the same stuck keys? I'm wondering if Sticky Keys got turned on - check the Universal Access Preference Pane for clues.

Haven't thought about that; I'll try it. Anything...Only I have the drive in a 2.5" drive cabinet at the moment, which is the way I retrieved the data. My (wild?) theory was that those keystrokes...caused by a short rather than *a hand* are somehow *frozen* in transit between the keyboard...and wherever they go to...on the motherboard? Just like certain key combinations *set* your mac in a kind of waiting mode (special characters...) the strange thing is, that (most of) the F-keys work... Desktop Macs have a reset button which I had to use now and then, and which solves A LOT OF problems... Bottom line; I'll never buy a new motherboard... So I'll keep trying!
