T510 Snow Leopard DSDT help needed, please!

[monty_mcmont]

Hi all,

I've been setting up a DSDT file for my Thinkpad T510 using the DSDTSE software (http://www.kexts.com/view/459-dsdt_simp ... 1.4.3.html). I have managed to resolve all of the DSDT compilation errors, and I've successfully applied the fix to enable sleep mode when I close the lid. Closing the lid only puts the computer to sleep when it is running on battery power, but that's fine for me.

Unfortunately I can't seem to fix the following, despite a lot of research on forums. Can anyone help me to solve them, please?

1. When I put the computer into sleep mode, it wakes up because of activity on the EHCI USB bus. I know this from /var/log/kernel.log, for example:

Aug 13 15:12:32 Montys-Mac-Pro kernel[0]: sleep
Aug 13 15:12:32 Montys-Mac-Pro kernel[0]: Wake reason = EHC2 EHC1
Aug 13 15:12:32 Montys-Mac-Pro kernel[0]: System Wake
Aug 13 15:12:32 Montys-Mac-Pro kernel[0]: USB (EHCI):Port 1 on bus 0x1d has remote wakeup from some device
Aug 13 15:12:32 Montys-Mac-Pro kernel[0]: USB (EHCI):Port 1 on bus 0x1a has remote wakeup from some device
Aug 13 15:12:32 Montys-Mac-Pro kernel[0]: USBF: 4233.867 AppleUSBEHCI[0x6b58800]::ResumeUSBBus - controller took (9) turns to get going

My Wi-Fi dongle is attached to bus EHC1 at address 0x1d, and my internal webcam and USB fingerprint reader are attached to EHC2 at address 0x1a. Does anyone know how I could prevent these devices from waking the computer up from sleep mode? I have removed the NullCPUPowerManagement.kext file from /Extra/Extensions because it was preventing the laptop from entering sleep mode at all.

I have tried sleepenabler.kext but it always causes a kernel panic at boot time.

2. Shutting down the computer doesn't work. The OS shuts down but the CPU fan continues to spin. Only a hard reset by removing the battery will switch it off.

3. The screen brightness controls don't work. Does anyone know how to get them working?

I'm sure that the right tweaks will be able to resolve these issues, and I'd be really grateful for any help. There are also 13 miscellaneous warnings that need to be resolved, so any assistance with fixing those would be great too.

I have uploaded my DSDT file to http://www.personal.leeds.ac.uk/~chmcje ... 510-v2.aml

Many thanks in advance,
Monty
