You may have to disable the second battery (return 0 from CMB2._STA). You do need to install ACPIBatteryManager.kext (ioreg shows it is not installed). 1 Link to comment https://www.insanelymac.com/forum/topic/306131-need-help-fujitsu-e752-battery-and-usb/#findComment-2135042 Share on other sites More sharing options...

I attach the new ioreg You need to disable the second battery device (CMB2). Change _STA in CMB2 to return zero.

carbo178 Posted May 13, 2015 Author Share Posted May 13, 2015 Return (Zero) is already present in the Method _STA of device CMB2, so i deleted the device and the battery works well; thank you Rehabman You're great!!! Any tip for the USB? Link to comment https://www.insanelymac.com/forum/topic/306131-need-help-fujitsu-e752-battery-and-usb/#findComment-2135251 Share on other sites More sharing options...
RehabMan Posted May 13, 2015 Share Posted May 13, 2015 Return (Zero) is already present in the Method _STA of device CMB2, Doesn't matter if it is present or not. What matters is what it actually returns. Removing it is fine too, but you could have edited _STA so it always returns zero. The last ioreg you provided showed it returning 0xF. Any tip for the USB? You probably need DSDT patches for USB3/USB2 multiplex. 1 Link to comment https://www.insanelymac.com/forum/topic/306131-need-help-fujitsu-e752-battery-and-usb/#findComment-2135282 Share on other sites More sharing options...

Ok, I try and let you know Rehabman, you're a wizard Thank you for all, i have re-edited my original dsdt, i have disabled the second battery as you suggested (Return (0x00) instead of (0x0F)) and applied your patch for USB Multiplex. Now everything works well Thank you so much again Link to comment https://www.insanelymac.com/forum/topic/306131-need-help-fujitsu-e752-battery-and-usb/#findComment-2135285 Share on other sites More sharing options...
