  1. Hello, 

     I wonder if there is any kext needed for Dell e5520 to make the sd card reader work. Must I modify something in the clover as well ? 

    Also to uninstall some kext that not work for it I just go and drag it to trash?

     

    PS. I have the O2 micron card reader in this Dell ...

    Yes, use Rehabman's latest ACPIBatteryManager.kext will resolved that issue.

    More info here

     

    Great! This fix the issue,  going with the first 2018 versions ( second latest 2018 version not show the charging icon). Can I also install the latest USB kext (I don't know if it is the rehabman inject all version will work) and also the latest trackpad kext from Rehabman or this need modification?

  3. Hello,

     I have some crashes in the Activity Monitor when I select the Energy Tab. I read in a previous post here in the forums that this affected by an ACPI Battery Kext. Can I use Rehabman Kext for this or must I compile my own kext for the E5520? Can I remove the energy tab from Activity Monitor? What is change from the old and new kext... is it something important, that can cause instability?

    Remove the battery and only use the power adapter, see if you still hear the high pitch noise.

    Happy Christmas!
    Thanks for your continue support on this topic! Thanks to all that contribute to make the installation package possible!
    I have made a lot of tests test days and I conclude the following:

    0) A (regulator noise?)Strong noise raise for some mili-seconds while booting and then disappear while booting, and the rest of mixed noise is appear especially while have disk, USB IO Operations and while charging.

    A) Using Power adapter, the noise is in lower volume and appear only while have disk, USB IO Operations.

    b) Using battery the noise is little bit more ( while laptop charging) but, it is acceptable as I state in the previews posts.

    C) I run a Linux OS on the same machine and laptop do similar noise while have disk, USB IO Operations but in lower volume. 

    D) In windows 10 laptop also do this noise, but it is in lower minimal amount.
    I must make this test earlier, this is my fault.
    From the above, it seems that the laptop in in good state, but I have two more questions before we close the post:
    Can this Laptop Support OSX Mojave using similar procedure as Dosdude patch?
    I can afford this noise, but can this noise make serious damage (for that mili-seconds that I hear the strong noise)?

    No hi pitch noise. Perfectly quiet. Brightness control works without icon on screen. Sound control works and shows icon on screen. Both brightness and sound control do not always remember the last value, so need to set again after reboot. The delete key works perfectly.

     

    As written in the initial post, I have used the guide from OSX Latitude for the E5520 and it works flawlessly now.

     

    However, there is one thing with power management I am still working on: booting from battery results in a kernel panic and removing the power plug when the system is running hangs it after 2 seconds. So I think power management (ACPI) is not yet configured correctly. 

    Also in my setup both brightness and sound control do not always remember the last value, so need to set again after reboot as well! I use Sierra .4 version and I have this high pitch noise especially when i run on battery, but no kernel panic at the moment. Just this high pitch when i run on battery it is not so hard i can afford it, but i am afraid for any damage in hardware level. I can make more tests if it is required and post back here. I use the configuration from the tutorial here in osx latitude and i update only the sound driver from the files below the tutorial, but it does not fix the hi pitch. I will try this laptop with Linux to test if makes this sound and i will post back.

    If you look at the link I provided, you'll see it's listed under the unsupported section. You'll need to replace it.

    Follow the link I provided to upload the debug file


    This is what i manage to get so far for the hi pitch noise. I can update the file once I have a compatible dell dw1510 card because the laptop rj45 ethernet is not fully functional.

  7. Hello, 

     Thanks for your reply! I have a wifi card dell dw1501 (update: this card is incompatible confirmed) and i try to make it works. I have it installed in the system during the installation process.  It seems that is detected by the mac os but not installed on it. I try some fixes from varius paces with no luck. For high pitch noise it might be from speakers or from the left side of the laptop. I dont know if it was because i run on battery..... I have installed the latest version of el capitan sound kext from the guide.... i can upload files if it required like the efi folder and library extensions...
