Instructions for doing so are as follows for several systems: Possible Solution: Resetting the PMU/SMU Another procedure that has resolved wake-from-sleep issues for some users is resetting of the PMU (power management unit) or SMU (system management unit) dependent on the Mac model. So, for now, I'm back to using a corded mouse (along with an Apple bluetooth keyboard, which works just fine)." When I power the mouse back up, and re-pair it with my system, the problem returns. Also, the problem occurred whether or not the Kensington MouseWorks software was installed.
However, I found that after removing my Kensington Bluetooth PilotMouse (actually taking the batteries out), the problem seems to have disappeared. This generally happens when the computer wakes from sleep. The system becomes totally unresponsive, where not even the force-quit window can be launched. "Since installing Mac OS X 10.4, I've had about five hard crashes of my system. Put Tiger to sleep and was able to wake immediately without any problems."įinally, MacFixIt reader JD was able to resolve wake-from-sleep issues by unpairing a Bluetooth mouse manufactured by Kensington from his system. Remembering that I had a media card reader plugged into an internal Orange Micro Firewire/USB board, I pulled the device from the board and restarted. "I had a similar experience where Tiger wouldn?t wake from sleep after an erase/clean install. If I boot from the 160GB drive in 10.2.9, I can also put it to sleep and wake it with no problem (this is with both drives installed)."ĭylan Menges describes a case in which a FireWire/USB PCI card was causing similar issues: If I remove the original 160GB drive and boot from only the 74GB drive, I can put it to sleep and wake it with no problem.
The only thing I can do to get it working again is to do a hard reset. The problem I have is now when I put the G5 to sleep in Tiger and then wake it up, the screen comes on but I get the dreaded spinning beach ball. I left the original 160GB Seagate Barracuda in the other drive bay (it still has 10.2.9 installed on it). "I have a Dual 2.5 G5 and I just installed Tiger onto a new 74GB Western Digital 10,000 rpm Raptor drive. One reader describes a case in which removing an internal 160 GB drive connected via SATA resolved wake-from-sleep issues: Wake-from-sleep issues continued We continue to receive reports from readers whose Mac OS X 10.4-upgraded systems will not wake properly from sleep, either refusing to wake completely or freezing upon wake-up.Ĭonfirmation for device removal As noted yesterday, errant devices (or devices, one way or another, in conflict with a Mac OS X 10.4 installation) can cause problems with waking from sleep.
