OS X 10.6
I use deepsleep widget to put Mac into hibernate without powering DRAM. However Mac always wakes up like 2 hours later unexpected.
Things I've checked:
- No scheduled wake up in Energy saver
- Wake for network access is turned on in Energy saver (guess this would be the cause. If so, can I still leave it on and keep Mac from waking up unexpected?)
Wake reason = ECH1 OCH1 ECH2 OCH2
compared with the usual wake up by any keystroke on keyboard
Wake reason = ECH1
What could cause this? How to avoid the expected wake up? Thanks.
