Ok, well, I think we can conclude that your USB key/HDD preparation is not good. Can you try with another device? Assuming you have a good/genuine OS X image, you should obtain a good fully bootable installation media with myHack once you add your model-specific /Extra contents at the end of the process. No messing around with kexts or anything else at that stage, so I'm a bit curious as to your remark about the SleepEnabler kext...

3.0, 3.1 The download listed in the EDP pages is for the tiny shell script which, when run, will download the latest EDP version. It doesn't really matter to us whether it's a 3.0 or a 3.1 version (that's more for those clever cookies who develop and maintain the tool), it's sort of transparent to us. A new feature of these last few days is that when you re-run your EDP tool command, it checks if an update is available and you can choose option 5 to update if you wish. You may notice that 3digit revision n°, which is currently at 410.

7hours! There's something very wrong with your USB device! Which stage were you at when you got this KP? Was it a reboot post EDP installation?

So, its 32bit only then, until you swap it out...

Ok, I have a MT362 BT adapter in the D630 and although it's detected, it won't work: can be detected and cannot detect anything. I have a BT adapter in my Inspiron 6000 under Leopard and that works perfectly (I think I had actually removed it from the D620 a couple of years ago). I don't have that old banger with me at the moment, so cannot check the model. Are there any models that are fully supported on the D620/D630 under Snow Leopard & Lion?

Pity this does not work on the D620. If you enable Wake on USB, the D620 won't go to sleep at all (or it does, only to wake up immediately).

The driver for putting the computer to sleep. Install it.

Excellent, congrats! I see you have an SSD drive. How long does it take fast to boot into Lion?

Intel graphics or nVIDIA? It's not the same bootpack for both, so make sure you're using the correct one...

Could you give us your D620 specs? You're installing SL retail 10.6.3, right? You should also follow, not the above guide (which is kind of obsolete now), but that fully documented in the EDP pages: http://www.osxlatitude.com/edp/ It'll get you through without headaches.

Great video indeed. It's possible to do it without so much dismantling, but it does require a bit of dexterity. When you change your CPU, I'd strongly recommend that you do the following: - clean off dust of the CPU fan, it's a perfect opportunity to do it (hoover does wonder there) - wipe any thermal paste residue off the new CPU + heatsink's bottom - put a rice grain-equivalent of ArticSilver 5 thermal paste on the CPU and apply it evenly to the surface before putting the heatsink back into place (buy some AS5 if you don't have any paste at hand, it only costs a few bobs). This will ensure best possible cooling for your CPU.

CPU change is not too difficult but it does require a bit of dismantling. Anyone with a bit of time and patience/care should be able to do it. D620 will support any Intel C2D with FSB 667MHZ, the T5600 being one of them but not the best. A T7xxx is a much better choice with bigger cache and higher frequencies.

Sounds like your installation USB key is invalid: it's not booting. Re-install Chameleon on it and give it a try, or re-un myHack completely if that is what you used. For SL, I was always using ModCD, not myHack, so here's an opportunity to play again! (sad...)

If I'm not mistaken, there's an Intel tool for Mac that provides the CPU model. It's not at all like a CPU-Z tool, but does the job in terms of CPU identification. Then you can consult the specific pages for the CPU model/family. Wasn't it supplied as a tool in previous releases of EDP to think of it?

Indeed, you can recover from black screen by putting the D620 to sleep (close lid or press Fn-ESC) and then wake it up. The other problem with this black screen thingy is that it won't let the computer go to sleep automatically. It seems to hold that feature.

Did you try to bootload your new Lion system via your USB installation key (boot off the USB key and press [ENTER] when the Chameleon delay bar starts scrolling, then select the new Lion installation)? This should let you boot your new Lion system for the very 1st time, finalise the OS settings and get you to the desktop. You can then install EDP to secure things off and be able to boot directly off the hard disk from there on. It always works for me on D620 nVIDIA or D630 Intel, so I see no reason why it'd be different for a D630 nVIDIA...

Yes, the USB ports are not electrically fed when the computer goes to sleep and, consequently, cannot supply 5V to connected devices. Not really a surprise, it is an expected behaviour during an energy-saving mode after all. This can be somehow/partially controlled in the BIOS. If you enable the USB wake feature, the USB ports will remain electrically fed when the computer is connected to the mains but not when operating on the battery.

I don't know (yet) what causes that black screen issue, but it's bugging me. The D620 does that in SL and in Lion, grrr. I think I had seen a message from Leon that indicated a possible AppleIntegratedBuffer kext issue. To be confirmed... I have found that an alternative to setting the Energy Saving parameters to off/never via the Preferences panel is to open the Chameleon Boot plist in /Extra with the wizard and set the "darkwake" parameter.

I do the kext installation (you don't choose any order there), then I do the hibernation fix and then the S/L/E fix. Obviously, I'd always do the kext installation before the fixes...

Yes, it's a known minor problem. Just disable Intel Dynamic Acceleration in the BIOS (Performance -> Dynamic Acceleration) and you'll see the expected frequencies within Mac OS. See here: https://osxlatitude.com/index.php?/topic/1388-d630-intel-screen-goes-black-during-boot-to-install-snow-leopard/page__gopid__9358#entry9358 IDA is not a critical feature, it only allow a very brief/temporary frequency boost of 1 CPU core when the other core is idle (for e.g., on my 2.2GHz T7500, IDA would allow occasional brief boost of 1 core to 2.4GHz). Not much gain in terms of real performance to be honest.

Yes, you should be able to upgrade to 10.6.8 without hiccups but maybe your downloaded combo upgrade is corrupt. After the installation and before reboot, re-run EDP 3, re-install your kexts and myFix will automatically be run at the end. You can then reboot to 10.6.8 successfully. Out of curiosity, how did you disable screen off?

I'd be interested to hear if you experience the 'black screen' issue. This is when the screen goes off before the computer goes to sleep, but when you try to reactivate it, it stays dark. Found a workaround, but it seems to have other side effects...

Yes, those D4x0 models need specific BIOS settings to avoid KP at wake from sleep. It's well documented on "Tweaks" pages of this site, but basically, you need to do 2 things in the BIOS: 1) set a System password 2) set password bypass on reboot/resume It's a bit annoying on initial switch on, but afterwards, no need of the password and you can put the lappy to sleep & wake without problems.

Don't worry about the error messages, they won't prevent anything from working. Now, re: lack of sound, I guess you proceeded with "pre-defined values" for kexts in EDP. Run EDP again and opt for your own values this time. Choose 'VoodooHDA (more stable)' option and you should get your sound back. That's how I fixed it.

Sounds like a duff installation. How did you create myHack USB key and with which version/media of Lion?
