smcbatterymanager.kext remove, thanks
If the adapter is not plugged in, SMCBatteryManager.kext causes more error messages at startup. ACPIBatteryManager.kext offers a better solution.

[Guide] Native Power Management for Laptops

Overview Power Management should be one of the first things implemented when trying to install OS X on a laptop. Because of heat/noise and battery life issues, using NullCPUPowerManagement is not a realistic option on a laptop. Fortunately, with Clover, NullCPUPowerManagement is never needed...

You should implement the process here and use it as ssdt.aml. Your processor is i5, you have to create ssdt.aml for it.

In the attached file you should replace EFI_840_G2> OC> ACPI> SSDT-8x0G2b.aml with your own .aml file. I also put it in zip.

for proper acpi patching I think to take dsdt.aml auto patched by clover pressing F5 key. not shure if it will be right.

Do you have an efi folder on USB that you can launch? You can try this out, but a backup usb should be available just in case.
