Lenovo Z580 Mav Installation

In the bios.

Keep in mind ~20 sec delay. Test with that in mind...

Also, according to your ioreg, IGPU PM is not done. Third party stuff like 'Boom' can also cause issues. Try to avoid that kind of software until your system is stable.

IGPU PM comes from renaming GFX0 to IGPU. If you implement brightness controls...

HD3000/HD4000 Brightness Fix:
DSDT Patches from here: https://github.com/RehabMan/Laptop-DSDT-Patch

Apply:
"Rename GFX0 to IGPU"
"Brightness Fix (HD3000/HD4000)"
- rename patch must be done first and to all DSDT/SSDT that contain references to GFX0 that you're including in your final SSDT set
- Brightness patch must be done to the DSDT or SSDT that contains the definition for Device GFX0 (search for 'Device (GFX0)'
- Place DSDT and SSDT (if necessary) into a place where the bootloader will load them. For Clover, EFI/CLOVER/ACPI/patched (DSDT.aml, SSDT-x.aml where 'x' is a number). For Chameleon, /Extra/ssdt.aml, /Exra/ssdt-1.aml, /Extra/ssdt-2.aml, etc.

Awesome. I did the IGPU PM from the thread Related to it. However, if I may ask one more question.

My laptop battery is 4400 mAh and its almost 8 months old.

I was just going through the System Report and I found that it stated that the battery has a full capacity of 2883 mAh.

Can that be a fault of the system? I believe this is the reason for my laptop since its showing only half of the true full charge capacity. I get that batteries degrade over time. But 50% in such a short time is too much.

Its showing 481 cycles too.

Some Lenovo laptops have a battery saver mode (which sets max capacity to around 60%).

Do you have it turned on?

No. I always kept it in full charge mode. This was handled by a software Lenovo Power Management in Windows. It could set the charge mode to 60%. But I never used that feature. Also I do not have Windows anymore. Both hard-drives are dedicated to Mac.

What is MaxCapacity and DesignCapacity in ioreg?

Also, I notice you're using VoodooBattery. Better to use ACPIBatteryManager.kext (less bugs). See: http://www.tonymacx86.com/mavericks-laptop-support/116102-how-patch-dsdt-working-battery-status.html

Either:
- battery is degraded
- DSDT is buggy
- battery saver is on
- VoodooBattery is buggy

Ok. So battery saver is off. As the software no longer exists. There is no option in the bios. Never used it.

How do I know whether DSDT is buggy or not?

I am currently going through your thread on patched DSDT for battery status.

The last option is to buy a new battery which is *hopefully* the last resort.
