I've recently set this up and there are some learning curves with this build. Still no power management, stuck at 3.5Ghz (can't turbo, or downclock in idle state) even though x86platform shim seems to load. Can't run more than 1 dedicated GPU but at this point I no longer need to do so due to...

Hey RehabMan, I'm a bit confused as to why the keyboard mappings behave differently between 10.10 and 10.11. My DSDT has EC mappings to PS2 codes which works perfect in Yosemite, however in El Capitan they behave differently. In El Cap my F5 / F6 do brightness as shown below but F10 /...

Tried booting to 10.11 installer (on another partition on internal drive) but I'm unable to boot due to error. Error shown is: "OsxAptioFixDrv: Error - requested memory exceeds out allocated relocation block" Here is a photo of the full error message: Without resolving this issue I...

Hey Rehabman I've recently upgraded the trackpad in the T440s to the trackpad from the T450s. Both are Synaptics touchpads, just the T450s trackpad has the touchpoint buttons on it and clicks differently rather than being spongy... Anyways I was hoping that you might know how to fix /...

Rehabman... So I modded the BIOS with an external programmer (didn't need to remove from board - used a clip method) and now my whitelist has been removed. I now have built in WiFi from the NGFF card BCM94352Z + BT 4.0 Combo card. Using: BrcmPatchRAM.kext - your version from march...

This is a quick guide for the T440s... it should provide you with all of the features the laptop can provide. System: Lenovo T440s 20ARS0HB01 CPU: i5 vPro 4300U @ 1.9Ghz RAM: 12Gb DDR3L (4Gb soldered to motherboard, 8Gb in open slot) Graphics: HD4400, 1600x900 TFT LCD (I've upgraded to...

So I finally got around to using the ACPI debug kext and have mapped the brightness keys properly now to the correct Fn+F5 (down) and Fn+F6 (up). Looking for some help on the other keys.... Here is the DSDT patch needed for the Brightness keys: #T440s Brightness key fix # _Q15...

Hey Rehabman, Not sure if this is the best way to 'file a bug' on your version of VoodooPS2 Trackpad or not but I recently had a kernel panic caused by this. So on occasion the trackpad will stop functioning and since I've always got a terminal open for work related I can still use the...

So I finally got around to using native AppleHDA for the ALC292 chipset on this T440s... replaced VoodooHDA. The issues I'm seeing with using AppleHDA + AppleHDAALC are: Headphones no longer work properly just really loud static overlaying the sounds where as they worked fine with...

Hey I'm hoping someone here knows a way to do this... So I've got the following Broadcom card in my thinkpad T440s and attempting to boot with it installed leaves me with the unauthorized network card halt during POST preventing me from using it. BCM94352Z NGFF M.2 WiFi WLAN Bluetooth 4.0...

So I tried to use PhotoBooth and Preview and now I'm seeing CVMCompiler crashing constantly and these apps don't work. This is on the T440s with the HD4400 graphics. Booting with UEFI Only + CSM enabled. "Clover rev 3021 on Lenovo EFI" 0:111 0:008 KextsToPatch: 4 requested 0:115 0:003...

I've got Clover installed to the EFI partition. Booting in UEFI only mode with CSM disabled. "Installer version: v2k r3021 EFI bootloader" I've attached my config.plist file and a debug log and ioreg. For some reason with clover it sees 16GB of RAM but this system is maxed out with...

I've got a Lenovo T440s that you've helped me with (RehabMan and a couple others) for SSDT and DSDT patching. I've got powermanagement working based on the info in the older thread but this thing just runs too damn hot.... HW sensors show it hovers around 60*C most of the time in a room that...

Hey RehabMan ... you helped me out a lot with my T410, now I have a T440S to work with and its turning out to be less than fun so far. Full specs: T440S i5-4300U has well HD4400 8GB RAM (I have the BIOS set to allocate 512MB RAM to the GPU instead of the 256MB default which was set when I...

Thanks to this thread I've now been able to get working battery status on my Lenovo T410 (the patch that mentioned a T410 previously didn't work for mine). Mine is a 2516-DCU (core i5 560 2.66Ghz w/ bios 1.45 w/ whitelist for wlan which is a Dell DW1510 half height card, Intel GPU only)...
