Probook 6550b EHC2 Sleep

[griftopia]

So I have decent install of 10.11.5 on my HP Probook 6550b by following the Intel HD graphics bible on this website. The ONE issue I have at this time is Sleep instantly waking up. I've searched and searched and searched many forums but I am facing two challenges. First my Probook does not seem to be as common. Second, I've tried everything I could but to no effect.

 

I'm attaching my DSDT here. It has the EHC1,EHC2 replace with EH01, EH02 fix and I have also removed Method (_PRW,...) from under both Devices. Now my syslog says Wake reason is EH02 (used to say EHC2). Would really appreciate any help. I have tried everything that's out there to no avail

So I solved my sleep issue. Instead of removing _PRW I returned 0x09 instead of 0x0D. I got the fix after googling. syslog indicated sleep deprivation because of EHC2 and HDEF. For for those devices I return 0x09.

 

But now I have another problem. After laptop wakes up, I lose my webcam. I'm thinking it is because of HDEF _PRW fix. Can anyone help me with DSDT patch so I don't have to reboot to have use of my camera? I've attached my latest DSDT.

It is not valid to change the GPE index in the _PRW return package.
