Yosemite sleep deprivation

Sleep has always been flaky under Windows, but it has always been solid under Mac OS X until I "upgraded" to Yosemite. For the first time ever, I am having trouble putting a Mac to sleep. Sometimes it goes to sleep and stays asleep. Other times it wakes up almost immediately. Then I have to shut it down instead.

How old is it, and how much RAM do you have?

with 6 GB of RAM. I bought it in 2011, but "About this MAC" says the vintage is "Mid 2010".

And is 'Allow Bluetooth devices to wake this computer.' checked?

I find this is the culprit most of the time in non-sleeping or re-waking Macs.

I wasn't aware of the 'Allow Bluetooth devices to wake this computer' setting. I have unchecked that box. Thanks for the tip. I'll just have to wait and see if that takes care of my problem.

...it's meant to wake it upon a click or tap of the device.

However, sometimes a bluetooth device can spontaneously ping to see if it is 'needed.'

My Jambox bluetooth speaker was guilty of that, so I unchecked the wake box.

which uses Bluetooth. My speakers and keyboard are hard-wired. Here's hoping it was the mouse that woke up the computer.

Another glitch: sometimes when I type the letters don't appear right away on my screen.

even though I followed your advice and unchecked the wake box. Tapping the magic mouse no longer wakes up the computer.

I suspect there's a bug in Yosemite which sometimes causes my computer to wake itself up.

I have to watch it and make sure the sleep light starts flashing or it will stay on with the screen black, heating up. Then when I open it I have to restart it. I finally realized that if I touch the mouse or move it wrong that it stays awake/wakes up. If that happens and I lift the lid fast enough it saves me restarting.

Its done the same under the last 2 operating systems, I think I have snow leopard now. I don't know if I have enough room to install yosemite, the hard drive is pretty much full.
