Dell Latitude E5520

[Jake Lo]

thank you. 

 

created a new install drive with the extra folder from your link, now after booting, when the install should show me the screen, the display is black.

 

I think, the olny diff. from the downloaded extra is the CPU, its not an i5, its a i7 2620m, could that be the problem ?

 

same found here: https://osxlatitude.com/index.php?/topic/1301-no-screen-after-installing-lion-on-a-latitude-e5520/

 

 

will try to post a full install doc, when its running

 

regards

See if this DSDT would make any difference

Hi Jake,

 

tried that, but same behavior. How could I troubleshoot that best? Will try to install a generic extra.

 

kind regards

Check and see if this works. http://www.osx86.net/view/3757-[new]_intel_hd_3000__hd_4000_10.8.3_ml_driver.html

 

Edit:

ben_beton,

 

What's the resolution of the display?

If it's higher than 1366x768, try this DSDT

Hi,

 

gerneric didn't worked. the resolution is a good point, its full HD 1920x1080

 

Will try the dsdt this evening!

 

kind regards

 

edit:

 

the DSDT worked, great! 

 

After that, I tried the edp install, but after a reboot, the sys hangs. Will figure out, which kext causes the problem.

 

edit: I'm not able to get past the error:

 

 

 

any ideas, thanks!

 

thanks

Hi Ben,

In the EDP build menu you need to select to patch AppleIntelCPUPowerManagement.kext

Has anyone been able to get VGA out working?

[halbertweber]

For Retina-like resolution:

 

in Terminal:

 

sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES;

 

// by the way, you need to logout and log back in for this to take effect.

 

// P.S. Go to [Apple menu --> System Preferences --> Displays --> Display --> Scaled] after logging

// back in, and you'll see a bunch of "HiDPI" resolutions in the list to choose from.

PS

I set mine to "960x540 (HiDPI)"

I did this, and it didn't add any options to my Displays.  Rather, it REMOVED all options except 1366x768 and it removed the slider to adjust screen brightness.  Luckily, I can still control brightness with my Function keys.

Has Anyone been able to enable basic use of the trackpad?

 

I realize it can't handle multi-gesture.

 

thank you for any help with this

This works pretty good on my E6220. 

1. Copy VoodooPS2Daemon to /usr/bin
2. Copy VoodooPS2Controller.kext to /E/E
3. Remove AppleACPIPS2Nub.kex from E/E 
4. Remove any PS2 Controller from E/E
5. Run myfix/full
6. Reboot

​Of course you could also try different versions from bpedman if this doesn't work for you.

Jake,

 

Thank you for this.  I will give a try and report back with my results.

 

I have another question

 

Power Management.  Is there a fix for basic power management?

 

I actually will be leaving it on all the time as a media server (until I build a desktop hack)

 

I am noticing that when i get up in the AM it is frozen and I have to reboot.

 

Any thoughts on how I can remedy this?
