Great!
I knew it! But I'm not familiar in dsdt editing.
I will try when I'm back to my hack.

Need for SSDT drop or not?

good: extracted dsdt patched with Inspiron 15R N5110.txt+ your hdef patch, from the old guide.
bad: the latest which you uploaded to the new guide.

I also don't worry about the benchmark, it was only additional info for the Mhz issue.
(Anyway, only for fun: same hw and benchmark, Win7: ~5000pts / OSX: ~5500pts and the cpu can't run at full speed. Benchmark trolling ended! )
Maybe some problem with p-state detecting/setting?

Hi Mohamed,

I have used your earlier patch for my dsdt (and install method), and it works (almost) like a charm.
With the newest dsdt I have no backlight after boot and start an endless "sleep-wake up" cycle.
But my nb has only the HD3000 graphics, maybe it is the problem?
And another minor issue: the peak CPU freq. is 2673Mhz when I stress the system. But the i5-2410M max turbo boost freq is 2.9Ghz.
Under Win7, it works at 2.9 when need it.
Geekbench(32bit test, under OSX) also shows ~5500 points against the ~6000pts readable on the Geekbench's website at the same CPU (ok that is 2415M, but only the GPU speed is the difference according to Intel specs.).
What is the problem?
