DSDT Fix for Dell latitude E6410

[musicthebee]

I have been breaking my head with DSDT for the last 4 days to fix the issue with sleep.

The laptop goes to sleep but the fan is still working and cannot wake up from sleep. I need to power it off completely and restart.

I have extracted the DSDT from ubuntu and have tried various fixes but still no headway.

The fixes I have tried are:
- LPCB (AppleLPC loads up)
- DTGP
- _WAK
- removed LCD

and few others but no success yet.
The USB and SATA show up as built-in without any patches and I have tried with the patch as well but to no avail.

Any help will be greatly appreciated. I am attaching the unmodified DSDT and modified DSDT.

Thanks

P.S: Challenge has been to figure out why sleep is failing. No errors show up in system.log and kernel.log. Any insights there would be great.

P.P.S: After editing the DSDT, I have been successful in getting the speedstep working.
