Sleep problem : Cant wake from sleep without AC power (Charging)

[alfadog007]

So im having a strange problem where my laptop (Lenovo P400) wakes up from sleep immediately when it is plugged into AC power and charging. But when im using it without power (i.e., on battery) it doesn't wake from sleep and boots with no display. Then i have to manually switch off and restart again after which it starts for 3 seconds then again restarts normally back to clover bootloader screenIm running yosemite 10.10

Did you solve your problem? I have a Lenovo T440s with the same issue

AppleACPIPlatform 1.3.6 is wrong for Yosemite. Should be version 3.1. Restore the native kext.

Also, it is likely you have installed a GenericUSBXHCI.kext not built for Yosemite (it is not my build).

Always test sleep without USB WiFi.

You should also eliminate 3rd party software (I see: metakine_handsoff, ControllerMate, you might check for others).

By the way, how is the dual-battery situation working out?

The dual battery works fine, with HWMonitor i see the levels of the 2 batteries.

I'm wondering about the built-in battery status provided by the system...

 

[Tlacuas]

It shows the level of the battery that is "on line" at the moment =)

OK. And then it transitions smoothly from one to the other? I think it used to show multiple batteries in prior versions of OS X...
