I don't have a D430 at hand, but can you check the Video settings of the BIOS? There is a brightness default setting there on D6x0... I'd suggest to set it to max there too.

Looks like you have a very similar D630 as I do: Intel graphics and T7500 C2D CPU.

 

I initially managed to install Snow Leopard with ModCD and Retail DVD 10.6.3. I had no need of any flags to launch and complete installation. It's at the end that I encountered issues (black screen on my 1440x900 LCD) and I basically had to boot on an external display for Snow Leopard to switch automatically to my LCD at the end. Otherwise it was working 100%, albeit with legacy kernel, but the external screen boot method could not go on for ever.

 

Copying the OSXL bootpack/correct DSDT for my Intel 1440x900 model to /Extra then fixed the problem. What a difference!

 

It is from that base that I created a myHack USB installation key and re-did a vanilla kernel SL installation and subsequent upgrade to 10.6.8. No turning back since, except a move to Lion 10.7.4...

 

Oh, you probably know it but your Intel Wireless card won't work, it's not supported. You'll need to swap it for a Broadcom model (Dell-branded 1390 or Broadcom BCM93411--- will do).

Magic, hey? Please note that if you ever re-run EDP again to re-install kexts, you'll need to modify your CPUMonitor kext again as it'll be overwritten and you'd be back with TjMax at 0.

You have an Intel T2400, i.e. a Core Duo CPU. Lion needs Core 2 Duo minimal...

 

Either you upgrade to a C2D (eg: T7200/7400/7600 for instance), provided it is supported in your D620 (I'm starting to have doubts for some D620 these days) or you limit yourself to Snow Leopard.

 

The reason why I say that I'm starting to have doubts with C2D in some D620 is because another forum member is not able to upgrade his D620 to C2D. He's on a similar CPU to yours but he says a T5xx0 does not fit in. I, for one, have a C2D T7200 2.0GHz in my D620 and it's a fully legitimate D620.

 

When I look at the Intel doc, I see:

T2400 -> socket PBGA479, PPGA478

T5500 -> socket PBGA479, PPGA478

T7200 -> socket PBGA479, PPGA478

 

In other words, the same! So go figure...

Not that simple... There are several D630 models. Which one do you have? nVidia graphics, Intel graphics, which screen resolution?

 

You appear to have legitimate Leopard + Snow Leopard retail versions, so installation of SL should be a piece of cake (I myself started and reached success with Retail SL 10.6.3). All you need to do is follow rigorously the process detailed in EDP pages od this site and ensure you use the bootpack that corresponds to your model.

Hi, not sure PCIRootUID option is valid with SL. I'd say it's more likely to be 'PciRoot' and it should probably be set to a non-zero value (say "PciRoot=1") as that is the default value.

 

Upon installation, you may try to reboot off your installation media in case Chameleon was not installed (or not installed properly) and press [ENTER] as soon as you see the scroll bar. Then choose your newly installed SL partition.

 

I take it you've used the correct BootPack at then end of myHack OS X installer procedure...

 

Are you doing your installation with a proper Retail SL image?

Can you give us the specs of your D630?

 

I had success with Mod CD (with a bit of work & tuning) before moving to OSXL myHack/EDP method which is the best I've found until now.

 

If you follow the recommended process listed in EDP pages, you should be Ok.

How much memory do you have in that D620?

 

It would really help to know the full specs of your machine like some of us indicate in our signature (model, CPU, RAM Qty, HDD size, graphics card, screen resolution, etc.).

Which BIOS is your D620 running and could you check the BIOS settings, namely SpeedStep?

Can this kind of tuning be used on the D620 nVIDIA to fix the energy-saving black-screen issue?

I've sent you a private message. Let's get you sorted.

Either

- use Finder->File->Search then type the file name as provided with Syonagar

or

- browse through the hard disc tree, starting from the root. Extra is a folder located directly at the root.

I recently found out that, on my D630, I needed to re-enable the BT radio from within Windows to be able to use BT within MacOS. It seems that the enabling/disabling of the radio is stored somewhere in flash on the BT adapter (it's not in the BIOS, that's for sure) and that Mac OS does not access that flash.

 

If you can check with Windows (XP or 7) and, eventually, enable the BT radio if disabled, you may find your fix.

Tested Ok last night with:

• D630 Intel graphics, Lion 10.7.4
  
• D830 nVIDIA graphics, Snow Leopard 10.6.8
  

In fact, it'd be nice of you try this http://www.osx86.net/downloads.php?do=file&id=173&page=2 and report back how it goes.

Hi, I doubt it's a bug as such, more likely an unsupported model or one that requires either a new kext or a rebranding. For info, the Broadcom BCM94311 is supported "natively" and, provided the 2 cards are compatible (i.e; no major differences in operation and/or configuration), rebranding the 94312 into 94311 might work, if such rebranding is possible...

In theory, yes, you could run your CPU at FSB667, which would increase your CPU frequencies to 2.16GHz max (13x167 instead of 13x133).

 

The key point is to keep T° under control which is always the main problem on laptops, where heatsinks and fans are of reduced size and reduced capabilities. You'll probably need a bit of time and patience.

 

This is not really the place to talk CPU overclocking but, having successfully O/C'd a Pentium M 1.8GHz/FSB400 to 2.4GHz/FSB533 on my old Inspiron 6000 laptop, I should be able to give you a few pointers off line if you wish.

 

You'll also find many sites on the Internet with ample discussions on the matter and samples for your type of CPU and, of course, start with the Intel datasheet:

http://download.intel.com/design/mobile/datashts/31407804.pdf

 

To me, for a few $$$, it's a lot less hassle to get a T7xxx FSB667 directly.

Nope, my D630 Intel graphics goes to sleep and wakes up just fine under Lion 10.7.4 (and I'm not using the BIOS password fix).

 

Karpais, did you disable hibernation (option 2, EDP fix menu)?

You can clear the BIOS password by replacing it by a blank one. That'll remove the password. Meantime, you can also configure your BIOS to bypass the password on reboot/wake, that'll save you from entering the password all the time.

Yes, indeed...

 

1) I'm very surprised a T5550 would not fit, unless it was not a T5550 you actually got delivered.

2) the T5300 is FSB 533MHz and the D620 is meant to use FSB 667MHz CPUs. Unless you're trying to overclock the T5300 (which may be possible through FSB pinmod), it may not be usable at all in the D620.

3) you had mentioned getting a T5600.

 

I'm confused...

Just found this thread too. Don't know if it'll work, but you could always make a backup of your existing kext and try the version provided:

The Dell-branded 1390 card is a Broadcom BCM94311. I'd say there's a good chance it'll work if OS X can be fooled into thinking your 94312 is a 94311, i.e. rebranding.

We should also look at the specs of each card to ensure they're similar.

Did you use EDP3 from the very beginning or did you initially setup your laptop with an earlier release like 2.1/2.2? I was told moving from one to the other could create issues.

Sounds like it wasn't a laptop CPU but possibly a desktop one. What's written on it?

Hi madmax,

 

You need to ensure you point to the correct .dmg image. Usually, you need to open up the initial Lion image and extract/point to the proper installation image, called "install ESD".
