I'm not familiar with the guts of that model (meaningI haven't stripped one down, yet), but if you can remove the keycaps do that and then let it sit somewhere where it's warm (on top of a computer or CRT monitor) and let it set for a week. If that doesn't work try a month Normally for something like this I'd wash it with Isopropyl Alcohol but that only works if you can wash the water and juice off the keyboard. If you can't open it up it would just move the contaminants around. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Don't know if this will be helpful with the aluminum. A friend used to get a lot of earlier keyboards that had had spills from a local shop. He found damaged traces and used a trace pen to repair them.

Thank you very much! So I will keep the keyboard around; soak it several times and "spin it around" a bit, and hope for the best. I’ll also look out for isopropyl alcohol. I hope that no damage has been introduced by connecting it while possible moisture (or worse!) was still inside it. That was very helpful! So again, thank you very much!

On Jan 16, 2013, at 2:42 PM, Mac User #330250 wrote: Could it really be broken beyond repair? All suggestions are wellcome… I suggest the 98% isopropyl alcohol soaking solution. They sell pure isopropyl as a gasoline additive to dry any water out of gas. Sometimes you can get pure isopropyl from a pharmacy. It's almost impossible to get stronger than 98% due to the fact that it absorbs water so easily. Isopropyl & water are miscible (mutual solvents of each other) and normally exist in equilibrium at 88% isopropyl & 12% water. Anything stronger than 88% will absorb water and evaporate that water relatively quickly. The problem with the keyboard is that the contacts are in flat, thin sheets that absorb liquids by surface tension capillary action, so it will be hard to get all the juice to dissolve out from these restricted areas, and you might need to soak the keyboard several times, perhaps swinging the keyboard hard to use centrifugal action clear the dissolved juice before soaking again. Then let it dry a good while in a warm environment before using. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Spillage on keyboard - broken beyond repair?
Hi! Yesterday I spilled some juice all over my Apple Keyboard.

I inverted it and allowed it to try for about 20 hours. I later found that 24 to 48 hours would have been better: http://guides.macrumors.com/Spilled_Liquid_On_My_Mac_or_Keyboard The good news: the built-in USB hub works.

The high temp of the chip may be due to a poor solder connection - I have reflowed ball grid arrays on graphics card gpu chips which were faulty due to heat problems caused by stressed solder joints - strangely enough the stress was caused by high operating temps due to poor heat dissipation like a faulty fan or heatsink contact - sometimes the fans and vents were entirely blocked with dust bunnies and gunk.

Good advice but, as I said before, I consider disassembling the G5 my last possible chance. Since right now it's working (thanks to the "hair dryer trick"), I don't want the burden and the risk to disassemble it and - maybe - break something else. :-/ I was looking for an advice to improve the U3 temp, *without* disassembling the whole shebang. :-) -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
