Apple Aluminum Keyboard Low Power Warning

If your Aluminum Apple keyboard suddenly tells you it can't power a USB device anymore (that it once did power without issues -- WTF Apple?!?), try unplugging the keyboard for 30 seconds and then replugging it. My SD card reader works again after doing that, though the LED no longer lights up. My Logitech camera (that once worked plugged into the keyboard) seems to not work anymore. I wonder if this was a change from Leopard to Snow Leopard?

Apple makes great stuff, but they'll just randomly change things sometimes, seemingly unconcerned with the problems those changes will cause to their uses. Rakin' frakin'...

Just had this problem on my late '07 Alu iMac. never had any bother before, it was always possible to have the wired MM and 5th Gen iPod attached. Today got a low power warning on just the iPod! (wireless MM now)

I unplugged it and reconnected after 20s - was all fine again. How odd.

interested on the power discussions here, the system profiler says the ipod is drawing 500mA thru the keyboard, and the keyboard itself only needs 20mA

Shutting down with the newer keyboards

Losing my old Kensington keyboard means losing my power button. But even though I can't power up from the keyboard anymore, I can still shutdown or restart easily:

Apple - Support - Discussions - The ole keyboard shutdown ...:

Hit CTRL (yes, CTRL, not CMD) and EJECT key. This will bring up 'Are you sure you want to shut down.... dialogue box. Once in there, hit enter/return for shut down or hit 'S' to sleep.

And to bypass the dialog:

Apple - Support - Discussions - Power up from keyboard. ...:

Sleep = opt + cmd + eject
Restart = ctrl + cmd + eject
Shut Down = ctrl + opt + cmd + eject

New Apple Keyboard!

Well, this New Year's Eve, I stupidly spilled coffee into my old Kensington keyboard, while typing away over at GtrOblq. Even though I took it apart and used a hair dryer on it, the bottom row of keys refused to come back to life. So, we did a mad dash to the nearest Best Buy before they closed for New Year's Eve, and I purchased one of those slender, new Apple keyboards. We didn't have time to make it to the Apple Store at La Cantera, because everything closed at 6 pm.

Man, what a great keyboard! I barely feel like I'm typing, and it's so thin that I don't even need a wrist support! Yeah! The front housing is made of Aluminum, so it seems sturdy. I looked at the other Mac-compatible keyboards, but they all came with a mouse and were at least $20 more than the Apple keyboard! So much for that theory that Apple is more expensive.
