No battery recognition

Question

Hello, I´ve used niresh mavericks for a while and I had not been able to get the battery works as it should. I mean, it works, I can use my laptop without being plugging in but the battery icon doesn't show any information. I´ve tried to install VoodooBattery for mavericks but it didn't work, any suggestion what can I do to make it to work normally?

Thanks in advance!

remove /System/Library/Extensions/AppleSmartBatteryManager.kext 
 
Install VoodooBattery.kext and AppleACPIPlatform.kext to /System/Library/Extensions
 
you may want to rebuild the kernel cache to avoid issues

I´ve already done it but it didn't work. I removed AppleSmarBatteryManager.kext, reboot, used kext wizard to install both kext and rebuilt the kernel cache and repaired permissions from system/Library/Extension and nothing. it didn't work.

May if I unistall both kext VoodooBattery and AppleACPIPlatform, reboot and reinstall would work?

thanks for your reply.

Thanks in advance

I think VoodooBattery is the only solution out there

so nothing else what can i do? 

I selected Laptop battery during installation, may that cause the VoodooBattery not working??

unfortunately you have to do it by trial and error

try not installing any battery at install time, and then install voodoobattery

 

took me quite some time to get it to work on my ultrabook, but it works fine

always restarting from scratch, checking and unchecking various options at install time.

 

then installing kexts and rebuilding caches

so you got the battery working with the VoodooBattery.kext??

I'll try to reinstall Mac OS X from scratch and don't select battery in the installation and see if that's work.

Thanks very much!

Hello all.

I´ve tried what it was suggestesd before.

I´ve made a clean install of Niresh Mavericks without selecting anything related to battery. Then remove AppleSmartBattery and install VoodooBattery and AppleAPCIPlatform but it didn´t work. I still don't have any battery information. 

I´ve tried to update to 10.9.2 to try if it work but no luck...

I also tried another methods found on Google as install various kext as AppleBatteryManager (or something similar, don't remember the name exactly) with no luck as well...

Anyone know what else can I do?

I read something about patching the DSDT to make it work but I actually don't have any idea of how to do and what to do exactly...

Please I need help.

I also bought a new battery to check if it worked or not but it didn't...

Anyone know if there is others possible methods to make the battery information work properly??

Thanks in advance

Hi, i´ve tried other distros as iAtkos ML2 and not battery status neither... even installing VoodooBattery for Mountain Lion.

Anyone know what can I do to solve it?

I also tried to patch my dsdt to get the battery well working but in the tutorial says look for EC but when I look for it, it didn´t find any line of code with that...

I´m desperate. Please I need help.

I really would like to get it working. It´s a shit not be able to control the battery percentage to know if I need to charge or what...

Thanks in advance
