Tengokutosh Posted June 16, 2012 Share Posted June 16, 2012 I recently installed Lion on my Dell Latitude E6400 (10.7), and I'm having an annoying problem. Randomly, my keyboard and trackpad just stop working, and then I got to do a reboot to fix the issue. My specs are as follows if needed Dell Latitude E6400 Intel Core2 Duo P8600 OSX 10.7 & Windows 8 Dual Boot 4GB DDR2 RAM 160GB HDD BIOS Revision A32 Webcam and Fingerprint Swipe Link to comment Share on other sites More sharing options...
MrBryan Posted July 27, 2012 Share Posted July 27, 2012 Did you ever figure this one out? It's a problem that has plagued me since I've had this laptop (same one as you) I've seen it written up that interrupt requests are to blame and that certain versions of AppleACPIPS2Nub.kext or ApplsPS2Controller.kext will fix this...
