Two Leopard 10.5.1 Sleep Issues and Two Unacceptable 'Fixes'
Initially, we had two sleep-related issues with Mac OS X 10.5 "Leopard." Kernel panics in our MacBook Pro on waking from sleep were fixed with a new FirmTek eSATA ExpressCard driver (v.5.3.1) but we still have a problem with Dreamweaver CS3 unexpectedly quitting after waking from sleep. The latter is likely to be fixed eventually with an update to Dreamweaver.
However, the 10.5.1 update to Leopard has created two additional sleep-related issues, both afflict our MacBook Pro and one our aluminum iMac.
1. After we put our MacBook Pro to sleep, it wakes on its own some time later but the monitor remains asleep. First, we tried removing all directly-attached peripherals (a huey PRO, FirmTek Expresscard, iPod, iPhone and our FW800 Time Machine hard drive) but that didn't work.
Next we took the batteries out of our new aluminum wireless Apple Bluetooth keyboard--bingo! Apparently, the keyboard's power management feature occasionally polls the computer and causes it to wake. This did not happen with 10.5. This is not a problem if we use an original Apple Bluetooth wireless keyboard instead of the new aluminum one.
The fix--Turn the aluminum keyboard completely off by holding the power button until the green light goes off or move it more than 30 feet away or use another keyboard.
2. On waking our 15" MacBook Pro or 24" aluminum iMac from sleep, it can not be used because the monitor does not wake. The happens only occasionally on our MacBook Pro but frequently on our aluminum iMac. One has to press the power button until the Mac shuts down, then press it again to restart.
The fix--Set both Mac and monitor to never sleep, letting the screensaver take over after a short period.
Curiously, the wake from sleep/dead video issue has never happened with our Mac mini Core Duo nor any of our PowerPC Macs running Leopard. In fact, our PowerPC Macs seems to be completely problem-free running Leopard 10.5 or 10.5.1. [Update: Corrected aluminum wireless keyboard power off procedure.] [Bill Fox and Dana Baggett]
