Dear rezmez,
For battery indicator, you need to find the right kext. Have you tried all the battery kexts in EDP?
As for sleep, you can try the latest sleepenabler kext from voodoo project, generate s and p states in cham or check your dsdt to make sure the system states portion are there. You may also try without dsdt to see if sleep works. Also try the guide in the website on getting sleep to work.
Cheers!
