Default Any recommendations for improving battery life? - 05-23-2009, 07:29 PM

I just finished installing and upgrading to 10.5.7 via the mechdrew method (thanks!)

Just wondering if anyone has any recommendations on how to save battery juice?!

I have already disabled dashboard. Don't know if that will help much. But will definitely help reduce RAM usage.

Dim your screen to about ~50% or less if you're comfortable with it.
Disable the ethernet port if you are running wireless.
Disable bluetooth when not in use.
Disable wireless when not in use.
Any programs that load on boot that you dont need, remove.
Use VoodooPower kext for added speedstep settings (read DellEFI 1.2a5 thread)

You're guaranteed 4+ hours of battery life with the above settings.

I get currently get 4+hours of battery life leaving WiFi on all the time and screen at 50% with 10.5.7 and DellEFI 1.2a5. I do not use the VoodooPower though as it makes the unit whine when in low power, i found it too annoying for an extra ~20mins of battery life. I also still use Dashboard, i like that too much to give it up.

How do I do this? I'm new to messing around with BIOS, so I wasn't sure which option to disable (Bluetooth was pretty obvious, though ;-) ).

You can't disable the ethernet in the bios, but you can disable it in leopard.

1) System Preferences
2) Network
3) Highlight Ethernet
4) Select the 3rd button next to the + and - buttons below the Ethernet selection box and select "Make service inactive"

This will prevent the OS from constantly checking for activity on the port.....minimal savings...but savings!

Lol i didn't notice the high pitch whine until you mentioned it and I put the laptop next to my ear. What is up with that!?!?

oh and for the Ethernet, if you turn if off from bios setting, you can get much faster WIFI and bluetooth load up when you are waking from sleep.

Since I don't use ethernet often at all, I have it turned off from bios.

when you say disable BT, is there a way to toggle this besides in the BIOS? rebooting to toggle this is somewhat annoying... and when i turn it on in the bios, i cannot turn it off in osx- is this normal?

i too am wondering the same thing... mine says "bluetooth: on" but it is grayed out and there is no way to turn it off it seems. Any other way then going into the BIOS? sorry if this is a stupid question - first experience with a mac... thanks

Default Bluetooth Terminal Mod - 08-10-2009, 01:40 AM

http://www.mydellmini.com/forum/mac-...nal-mod-3.html

Check that thread.

Follow post by HussainX word for word. Your bluetooth toggle will be enabled in OSX.

I'm running 10.5.8 with that mod and I'm getting great battery life. 4-5 hours on my A90
