Default Warmth/Battery Drain While Sleeping - 01-10-2009, 09:11 PM

So I've finally put OS X on my machine using the Type11 7.7 disc. So far, everything is working very well. It reminds me of a much lighter/smaller version of my old iBook that I recently retired (plus it runs 10.5 instead of only going up to 10.4).

Anyways, I closed the lid to put the machine to sleep before I went out earlier today. I was gone for about 3 hours. When I got home, I picked up my Mini and opened the lid. Waking from sleep worked fine, but I noticed that the machine felt very warm--pretty much as if it had been running at full power the entire time. Also, the battery had gone from about 85% to about 20% in that time. Is anyone else experiencing this? From what I just described, it almost seems like closing the lid only turned off the display while leaving the rest of the machine running at full throttle. Is there something that I missed when setting up the machine?

And one other thing--it looks like the OS X audio driver also controls the volume level of the low-battery beep. But I'm sure most of you already knew that. I'm waiting for an "official" A04 release before updating my BIOS.

Thanks for all the great work you guys have put into getting this working!

I have also noticed my battery draining after I closed the lid it's slept for a couple hours.

It should only go down 2% per hour while asleep. Make sure the white LED starts to throb after you shut the lid.

"Only" 2%?!? My 7-year-old iBook can't hold a charge at all anymore (it literally goes to sleep immediately after unplugging it from the wall), but it can stay in sleep mode for about a week before the battery finally gives out. I would think that it should be more like 2% every day or two with the Mini...

And the LED was definitely pulsing when I came back home, because before I picked it up I remember thinking "Wow, it really is like the iBook's little brother" (I had the two sitting next to each other, both pulsing away). Anyways, I'm doing some experimenting with the Mini at the moment to see what might be going on. It seems to be sleeping much cooler at the moment. I'll see if I can reproduce what happened earlier and I'll let you guys know if I find anything.

It's asleep, it's not off. Yes, 2% is perfectly fine for battery drain while sleeping. If you shut down and turn it off, you won't lose any battery life.

Yes, I'm well aware of the differences between sleep and off (as well as deep sleep). When I swap out the SSD for my Windows disk I'll see what the power drain is like in sleep over there. I don't remember it being that high, but I guess it's possible that the Mini uses 5-10x more power in sleep mode than the other laptops I've used.

I've already done the windows comparison, battery drain is identical while asleep. The drain might appear lower with a Chinese battery, or A04 bios, because I have the korean battery which has it's capacity misrepresented.
