I find DSDTEditor to be trouble free. Give that a try...

The D620 is not a supported hardware platform for ML (unsupported GPU means no graphics acceleration - no OSXL bootpack - no 32bit kernel mode). If you want ML, you need to use a special installation that requires a legit' retail ML installation package + MLPF hack. Look for the guide in the relevant section of the forum. The Niresh distro will not get you anywhere useful or usable as it'll be a more "classic" installation but you won't know for sure what it installs.

myHack does not support Yosemite for the moment. So you can't use it to install 10.10. You have to use other methods that are well documented here or at other places like IM. You can then boot with Chameleon of Clover, keeping in mind that Chameleon will be a little more difficult to start with...

The WWAN slot can take a full-size card. It's clearly visible at the right of the 1/2-size card on the pictures in Jake's link. You can use it for a full-size WLAN card too (and probably for a 1/2-size card as well if it's anything like the E6440). Depending on your exact E5440 model (basically if you have nVidia GPU or not), the WWAN slot should support PCIe (WLAN), SATA (mSATA) and USB (WWAN). To give you an example: my E6440 was delivered with an Intel wireless/BT card. The E6440 has 1x1/2-size WLAN slot, 1x1/2size WWAN slot and 1xfull-size combined slot (clever use of space under the bottom cover: horizontal 1/2-size, vertical full-size). That full-size slot supports PCIe, SATA and USB modes. I left the Intel card in place and inserted a good old DW1490 in the full-size slot. I immediately obtained OOB wifi connectivity.

Mavericks has no support for the AMD 8xxx/9xxxx, this was introduced in Yosemite. As such, you'll never get graphics acceleration with current version of Mavericks (10.9.5) unless Apple brings out a new update that supports those. But don't bet on it now that Yosemite is out...

At this site, we advocate myHack as the installer tool. You have posted your thread in a myHack section, so... Follow the process detailed in EDP->Documentation at top of pages. Other methods you mentioned have their own web site with supporting forum.

Funny this need that people have to always go beyond specific instructions... Leave those Cx states alone and noone advised you to delete all those CPU parameters you've listed. Do you know what they do? As I said, just select GenerateCStates/GeneratePStates. If you really must change any other CPU parameter, only adjust the bus speed to the correct theoretical one (eg: 200000 instead of 199949 in the case of FSB800) and that will show show exact/theoretical speeds in OS X. Look up for the thread on performance tuning in R&D->Other Research section of the forum and you'll find what you're after.

You want Clover to patch it on the fly; that's a good thing; means you don't have to do it manually (patch the FameSMC kext to adjust SMC keys + smc-compatible). In addition, since Clover also selects the correct SMBIOS profile on the fly, that's another thing you don't need to worry about. Really, the only 2 parameters to check on the Clover config for native CPU PM are P+C states activations. If you disable kext patching in Clover, I guess FakeSMC will retain its default settings or the settings you might have edited yourself in the kext. GPU speedstepping can be expected too, but that really depends on the GPU itself (if it supports it) and your own computer platform... But, to give you an element of comparison, I can tell you that Latitude D630/D830 with nVidia Quadro NVS 135M/140M do show GPU throttling in HWMonitor with tuned FakeSMC kext and appropriate SMBIOS profile. Same applies to the Precision M4300 with nVidia Quadro FX 360M. I'm talking about Chameleon based installations here, but it should be the exact same thing under Clover.

All you need now is to select/activate CPU P&C states generation in your Clover config.plist. Use HWMonitor 6.11.1328 to monitor CPU speed stepping.

Then you're not suspending to RAM as stated. Your laptop is not entering sleep properly. Your DSDT probably needs patching.

Probably is, yes; I don't know all the parameters by heart. But that's the tool to generate the SSDT. Now select DropSSDT and do not select P&C states in your Chameleon boot plist of Clover config file. You'll then obtain Turbo boost of your CPU. Use MacPro11,1 profile to get extra intermediary speedster CPU multiplier.

If the laptop's power led fades in and out, you've got sleep and no, HDD and CPU are not still running.

First of all, you don't need any SSDT patching for CPU power management on Core2Duo CPUs. You just need a tuned FakeSMC, the correct SMBIOS profile and the activation of P&C States. Don't waste your time extracting tables you'll have no use for. Secondly, extracting BIOS tables to simply place them as-is in an /Extra Chameleon folder or an ACPI Clover folder will do nothing at all. You only use extracted files if you patch them! Search for the long-published articles and threads about performance tuning. SSDT for CPU PM really only applies to "i" core CPUs.

If you're trying to generate your own SSDT for the CPU power management, it's not the right process. Use the SSDT generator script and ignore those tables from BIOS.

I went to DP7, then the HDD failed miserably on me.

You would extract them all, but what do you intend to do with them?

Well, you kind of omitted the on-board discrete GPU in your description; you just stated to have an Intel HD4400, but that does not seem to be the sole case, does it? Instead you seem to have an E5540 with the additional nVidia GeForce N14M GE, i.e. Optimus.

Yes, I had installed Yosemite and sleep was indeed broken: https://osxlatitude.com/index.php?/topic/6728-vostro200-yosemite-1010/

And delete any sleep image file found in /var/vm with sudo rm -f Terminal command. Don't delete the swap files!

You could try and patch your audio device in DSDT to get it back after wake, as per E6440 patch: https://osxlatitude.com/index.php?/topic/7387-dell-latitude-e6440-with-i5-4300m-hd4600-and-1600x900-lcd-mavericks/&do=findComment&comment=44670

Of course it does, you missed the pack, that's all. It's a the bottom of post #9...

I would not use the E6440 DSDT on your E5440 unless it really is the same hardware. Remember that the E6440 I use also has a discrete AMD Radeon GPU for instance. I was able to boot, install and run Mavericks without any DSDT to start with, I just patched it as I was progressing with post-installation tuning. All you'll need with a Chameleon boot loader + myHack installer + generic bootpack will be to specify the correct Azul framebuffer as boot flags & options -f -v IntelAzulFB=xx (where xx is in the range 0 to 15). Start with 10 to 15. You may have noticed that my guide recommends using the USB port on the left... That one always works on the E6440, the rear+right ones not unless I bypass the cache.

It certainly should be able to run OS X all the way to Yosemite. If LAN or Wireless aren't supported (I have not checked that at all), it's pretty easy to add a wireless card or USB dongle that will be. Same principle with the HD4650. Give it a try...

Sorry, I have little experience with ATI boards (outside the X1300) and have only been using nVidia cards since. I find them easier to deal with (OOB or with patches) but that's probably a matter of experience and taste... There's a pretty good wiki at InsanelyMac for all sorts of supported hardware, including graphics cards. Just scrounge the web.

There's a new modded BIOS at bios-mods.com for the Vostro200. It widens CPU support to quad-core Yorkfield-CL and Harpertown Xeon CPUs. So, not all quad-core CPUs appear supported but interesting models like the E5450 for instance. X series are supported too but at 120W compared to 80W for E series at same or slightly higher speed (@FSB 1333MHz, E5450/X5450 run at 3.0GHz, X5470 runs @3.33GHz), E models should indeed be favoured for what are otherwise strictly identical CPUs. I've got an E5450 on order too. Running Ok on a dual-core Xeon [email protected] meantime. NB. Quad-core cpus are only supported on the G33M03, the G33M02 only supports dual-core CPUs.
