I usually do not use the track-pad, or the "eraser" in the keyboard much. I prefer a mouse, either wireless, or wired. I have seen signs of what you describe happening in the track-pad. I have not had time to look into this. The only thing that comes to mind is usually there are some parameters associated with a mouse, acceleration, for example. Perhaps they are not being restored.

Here it is. First some notes: For the D4X0, I used the DSDT from EDP 1.9 as a starting point. I do not know what chipset is used in the D4X0 machines, but I do know the D620 uses the ICH7 chipset. So the updates to the D4X0 DSDT are based on the D620. 1) The DSDT USB0-3 devices are UHCI devices. Using lspci and looking at the data sheet, I found these devices DO NOT have a power management capability in the PCI configuration space. I believe you can still have a machine that supports power management, but these devices are on or off. This is why I did not include the _DSM() methods in these devices. They were present in the D4X0 DSDT, so I commented them out. I figured it would be best to start with what worked for me. I also added the other pieces. 2) The DSDT EHCI device is an EHCI device. Using lspci and looking at the data sheet, I found this device DOES have a power management capability in the PCI configuration space. I did include the _DSM() methods in the EHCI device. The version that is in the D4X0 ECHI device was largely a super set of my version. Since I am not clear what side effects the additional items will cause, I commented out that version, and added my version. This may not matter. I also added the other pieces. 3) I changed the AAPL,Haslib to AAPL,HasLid in the _DSM method in the VID device. Lastly I suggest updating the BIOS parameters to match the values I used. Let me know how it goes. Joe dsdt_d4x0.tar.gz

Hi All, I have a D620 with a DELL TrueMobile 360 Bluetooth card. Overall it has worked well, but I loose the connection to my Bluetooth mouse after a wake from sleep. I have noted others seem to have the same problem from the notes in their signatures. I decided to look into this problem. After reading various forums on other websites, I decided to try some changes to the DSDT, specifically the USB* and EHCI devices. I compared the same devices in the DSDT from a Macbook1,1. The two machines are largely the same. I added the following to the USB0-3 devices. Method (_S3D, 0, NotSerialized) { Return(0x03) } Method (_S4D, 0, NotSerialized) { Return(0x03) } and the following to the EHCI device. Method (_DSM, 4, NotSerialized) { Store (Package (0x04) { "AAPL,clock-id", Buffer (One) { One }, "device_type", Buffer (0x05) { "EHCI" } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } Method (_S3D, 0, NotSerialized) { Return(0x03) } Method (_S4D, 0, NotSerialized) { Return(0x03) } With these changes, I am able to get the USB-based Bluetooth adaptor to reconnect with the mouse after a wake from sleep. I am also able to change the hibernatemode parameter in pmset back to the default value of 3. Here are my pmset values. Active Profiles: AC Power -1* Battery Power -1 Currently in use: hibernatefile /var/vm/sleepimage hibernatemode 3 disksleep 10 sleep 10 displaysleep 3 lidwake 1 ttyskeepawake 1 womp 0 acwake 0 halfdim 1 autorestart 0 To be complete, here are the BIOS parameters I have updated that are related to the USB. Onboard Devices External USB ports: Enabled Integrated USB Hub: High Speed Power Management USB Wake Support: Enabled POST Behavior USB Emulation: Enabled I am also running 10.6.8 with EDP 1.9. I have not had time to try EDP 1.9.1 or 1.9.2 When the EDP is configured, I choose all the Apple versions of the drivers. Although these changes seem to solve my original problem, I believe the DSDT is removing the power from the Bluetooth adaptor when going to sleep. This makes it hard to get a wake-on-bluetooth-mouse-event to work. I decided to start with a wired USB-mouse. Using lspci, I was able to verify the power management registers were getting set when this mouse was used. I was able to get the machine to wake on a usb-mouse button hit. Looking at the "Advanced..." tab from the "Open Bluetooth Preferences..." tab, wake-on-bluetooth-mouse-event seems to be supported, but the "Allow Bluetooth devices to wake this computer" is grayed-out. It seems I do not have a supported Bluetooth adaptor. I have been able to "trick" the OS into thinking I have a supported adaptor, but with the power being turned-off, it does not work. I have seen other people comment on this problem, and they have even found the line that disables the power, but their DSDTs are different. I will put this on my list of things to look into. If I ever find the way to keep the power connected, I will most likely try to get the wake-on-bluetooth-mouse-event to work. I am going to attach my modified dsdt.dsl and the compiled dsdt.aml files. Note this DSDT also includes a fix to get the VGA port to work correctly on a docking station. dsdt_d620_gma.tar.gz

It has been a while since I updated this, but I have some additional information. First, using EDP 1.7, I went back to see if I could add back the device-properties line in com.apple.boot.plist. After adding it back it still worked correctly when in the docking station. It also worked out of the docking station. The only problem I observed is then the screen entered display sleep. It does exit display sleep, but the screen seems to be at a lower resolution. It is still 1440x900, but it is as if half the pixels are not being used. I was able to track the problem to the option AAPL01,DualLink It seems with displays of this size, 1440x900, this needs to be set. So I updated and added the following "AAPL01,DualLink", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "AAPL01,Height", Buffer (0x04) { 0x84, 0x03, 0x00, 0x00 }, "AAPL01,Width", Buffer (0x04) { 0xA0, 0x05, 0x00, 0x00 }, This fixes the display sleep problem, and it still works in the docking station. I have also moved from 10.6.7 and EDP 1.7 to 10.6.8 and EDP 1.9. I have not had time to update to EDP 1.9.1 or 1.9.2. Things have changed in Chameleon since EDP 1.7. The com.apple.boot.plist has been changed to org.chameleon,Boot.plist. The device-properties is no longer present in the new file. The good news is these changes have not been a problem for this docking station fix. At this point I decided to look back at the fix to this parameter. "AAPL,HasLid", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, This parameter had been updated from AAPL,Haslid to AAPL,HasLid. I did a strings on /System/Library/Extensions/AppleIntelIntegratedFramebuffer.kext/AppleIntelIntegratedFramebuffer After pruning back some of the junk I got. AAPL,HasPanel AAPL,HasLid AAPL,NumFramebuffers AAPL,NumDisplays AAPL,DisplayConfig AAPL,SelfRefreshSupported AAPL,display-alias AAPL,boot-display saved-config saved-timing0 saved-timing1 AAPL00,CurrentDisplay AAPL00,IODisplayMode AAPL00,Pipe AAPL00,BootDisplay AAPL00,Depth AAPL00,Width AAPL00,Height AAPL00,Interlace AAPL00,Refresh AAPL00,EDID AAPL00,display-alias AAPL00,IgnoreConnection AAPL00,no-hotplug-interrupt AAPL01,DualLink AAPL01,T1 AAPL01,T2 AAPL01,T3 AAPL01,T4 AAPL01,T5 AAPL01,T6 AAPL01,T7 AAPL01,PixelFormat AAPL01,BacklightIntensity AAPL01,InverterFrequency AAPL01,CurrentDisplay AAPL01,IODisplayMode AAPL01,Pipe AAPL01,BootDisplay AAPL01,Depth AAPL01,Width AAPL01,Height AAPL01,Interlace AAPL01,Refresh AAPL01,EDID AAPL01,display-alias AAPL01,IgnoreConnection AAPL01,no-hotplug-interrupt So this driver does reference AAPL,HasLid. I have also found the same string in /System/Library/Extensions/AppleIntelGMAX3100FB.kext/AppleIntelGMAX3100FB I am not clear what systems use this driver, but the same fix might work in that case. Anyway this fix has been stable for me for some time now. I still have not found a way to get the DVI port to work, but it is still on the list.

No, the DVI port is still a problem. I would like to look into this as soon as I get time.

Hi all, First nice work by all. I have not been an Apple user, but now that I have access to a machine running the Apple OS, it has given me something to think about. Since I have an interest in using a D620 in a docking station, I decided to try the solution posted by "Fireman Sam". I was able to implement the documented changes, and found it worked at advertised. I started looking at why the DVI port did now work. I looked over "dumps" from real Apple machines, and found an interesting different between the Apple version of a variable, and the one in the D620 DSDT. The variable, from the EDP 1.7 DSDT is: "AAPL,Haslid" Apple uses "AAPL,HasLid" Note the "Capital-L". I updated the DSDT, and gave it a try. It still worked. I backed-out the DSDT change (detection of lid/dock), and gave it a try. It still worked. Using "system profiler" I was able to note the internal display was not "configured" when docked, but was when not docked. This should help save on power, I guess. So my modified fix is; 1) Remove the device-properties from com.apple.boot.plist (As documented by Fireman Sam). 2) Change "AAPL,Haslid" to "AAPL,HasLid" in DSDT. To be accurate, I did update two of the other variables, "subsystem-vendor-id", and "subsystem-id". This should not matter. I also noted that there are various other variables, in the Apple version. Most I do not know what they do, and I am not clear which should be in DSDT, and which should be in com.apple.boot.plist. This version of the fix, seems to move the decision making from the DSDT, to the OS level. This fix should be more portable across laptops, and other VGA chipsets. "Wake from sleep" still works. I did not try mirror, and there are still other things to test.
