Default Problems: No sound with Bluetooth, no force sleep on low battery - 12-21-2009, 12:21 PM

I am running 10.5.8 on a DellMini 9 with a 16GB runcore ssd and netbookinstaller 0.8.3 RC4. In General, this works just great, I only have two problems:

I can successfully pair my stereo A2DP headset or normal headset, it will show up in the BT menu, but I cannot connect/use it. When I select "use headphones" from the menu, nothing happens.
It will show an active connection to the device for a short period if I select "Update Device Services" from the Bluetooth preference panel, but that's all.
I can, however, browse the files from my mobile phone, so connection to other BT-services works.
It remember A2DP sound did work using DellEfi but it was crackling/distorted.
Maybe I can exchange the KEXTs for these Services? I would really appreciate some help here..

>Force sleep on low battery
On my original Mac, when the battery is below 5% there is a warning and after some time the computer will force-sleep.
This doesn't work on my Dell-Mini. There will be the same warning but the computer just runs till the battery is completely empty and is switching off suddenly.
I could not find much about that. So maybe this is a known limitation to this configuration?
Otherwise I really would like to activate the force sleep if, lets say, the battery reaches 3% or so. Any hints?

The system management controller (SMC) on a real mac is what forces the machine to sleep. This happens because the battery doesn't report reliable information, so the smc take over that function. I *could* modify the battery kext so that it forces sleep at a certain percentage, bet again, it's unreliable and may still have 30 minutes of life left, or may never even reach that percentage before it dies.

Hi Meklort, thanks for the fast reply, and thanks for netbookinstaller, it's an amazing piece of work.

Back to force sleep: you are right about lack of reliability. In my case, if the battery shows zero percent it will still run for a considerable amount of time (here it is never the other way round, shutting off before zero).

But I would always trade in this extra runtime for safety sleep time. So here's my suggestion: If the battery behavior is repeatable in general (it _is_ on my machine) then it would be great to have a force-sleep parameter.
