N5050 Lion 10.7.2 issues...


Recommended Posts

Hi all,


After a being a very happy d620 user the last few years I had to replace my ol' pall with a new Laptop since my LCD's bckligt broke down.


I bought me a Dell inspiron 15 n5050 i5-2450 / 4gb / HD3000 gfx / 500gb hdd. I've managed to get Lion 10.7.2 booting on my new laptop. But still have couple of thing that wont work...


I've been spoiled with edp on my d620 so now I'm struggling to get thing sorted out. Maybe someone can point me in the right direction in resolving these problems.


My Touchpad is not detected after installation. I've tried voodoops2 but without success. Keyboard works and external usb mouse also works, just no trackpad... My n5050 has a alps trackpad, but i can't figure out how to get it detected...


Also I can't figure out how to get my wifi working. According to windows it's a "Atheros AR9485 Wireless Network Adapter" and Dell says it's a "dell 1703 802.11b/g/n" VenID/DevID 168c:0032


Who could give me some advise? Any help is welcome!

Dear bjorn,


One of the crew has an Extra for his machine with similar model. I'll attached it when i get back from my trip for you to try. If it works we can add it to edp.




wow, that'll be awesome! tried a lot of trackpad kexts but never managed to get it working properly. Can use it when it's detected as a standard mouse, but no scrolling :( Seems my wifi card s not compatible so I ordered an Ebay (Atheros AR9280 AR5BHB92 Half PCI-E Wireless Card 300M) Should be detected OOB. I'll report if it works when it has delivered.


Looking forward to your attachment

My Wifi card from Ebay arrived by mail today. Swapped the original card with the Atheros AR9280 AR5BHB92 Half PCI-E Wireless Card 300M and as expected it was detected OOB. So a very cheap hardware fix: $10,50 in total.


Trackpad keeps buggin' me a bit though. Using a modified voodoops2controller kext for Alps from Projectosx.com I managed to get my trackpad to be detected as a "normal" mouse. Still, i'd love to be able to get side scrolling / multi finger scrolling working. For the time being I found out that when I click and hold the left + right mouse button simultanioualy and swipe over the trackpad It scrolls. Not very elegant but works better than using the scollbars.


I've been trying to figure out what the model (deviceID etc) of my trackpad it is but I can't find it. Does anyone know how I can find out what exact model the alps trackpad is? Some linux/windows/osx tool I don't know about?

For anyone interested, I've been running ML now for a while on my N5050. Most things work.


Not working: Ethernet, original WIFI card (replaced It) and Sleep


Here's my EXTRA folder.





For intallation I used myHack-3.1.2 to make a USB ML install drive. During installation choose Use Custom Extra Folder. Delete the problematic kexts MyHack asks for.


After installation I installed some kexts to S/L/E (2nd zip) to get sleep, audio, battery and touchpad working.


Touchpad is a work in progress, check bpedman's threat for progress https://osxlatitude.com/index.php?/topic/2545-new-touchpad-driver-for-e6520-alps/

The trackpad is fixed now, see this thread by bpedman https://osxlatitude.com/index.php?/topic/2545-new-touchpad-driver-for-e6520-alps/


side scrolling and two finger scrolling works fine now. I'm quite happy with my N5050 now. almost everything works now.


sleep is still a bit buggy, sometimes it won't go to sleep when I shut the lit or use the menu. No real problem, and haven't bothered to research it any further. Ethernet is not working, but since I don't like cables hanging off my laptop and Wifi works fine I don't mind.


EDP?  ^_^

I'm trying on the same box , got the installer USB 10.8.4 with myHack 3.3.1 when I start the installer it gets all those initial messages then it changes the resolution of the screen, it is supposed to get the messages in a smaller font, on the Inspiron I just get a blank screen and it freezes there, sounds like some video setting??? I did put the Extra there but didnt make a difference.


  Would you mind sharing your BIOS settings???


   Thanks in advance
