[Guide] Lenovo ThinkPad L440

[Sniki]

Install latest Clover Bootloader version or the one forked from Rehabman.
When i get back home:
- I will make a fresh config.plist
- i will make a fresh correct SSDT-BAT for your laptop (u are using the one from L450)
- i will make final SSDT-X240.aml

Will upload the files.
Then test if audio is working.

Im doing some changes/fixes/adjustments to my L440 and as soon as i correct them i will upload changes to the guides
Changes include:
- New Keyboard Map (All buttons work)
- FAN Speed code for HWMonitor
- Fix “No Sound” on Headphones when booting with headphones plugged in.
- Hotpatch Optimizations (config.plist/SSDTs)

I’m a bit confused! You mean to reinstall Clover and after that start using new SSDT Patches and new Config.plist?

Look at the differences in config.plist/ACPI/DSDT/Fixes.
The new config.plist requires new Clover that accepts those new names for Fixes.
I didn't check which version of Clover you have.
You should make sure you have the latest from my bitbucket.

You are right for new CloverI updated my Clover from last one /bitbucket/ and now my Audio start working again (still doesn't work after sleep/wake up)
Maybe you are right as well for SSDT-BAT, which I used from L450(makes from Shiki) because after new Clover my battery status is gone at all and can’t tick battery status . I will waiting the new finally SSDT-X240 and fresh Config.plist from Shiki and will make full report
PS: Used now Clover_v2.4k_r4270.RM-4359.cc5db5ba

Here is the new config.plist and SSDT-X240.aml

Hopefully now you should have everything working.

I re built config.plist and SSDT-BAT from scratch.

Hi Sniki, I removed old Patches and Confic.plist. Now tested new SSDT-X240.aml with new Config.plist but unfortunately nothing happens. I still doesn't have battery status and doesn't have a sound after sleep/wake up
Battery status - same screenshot like previous post

PS: Do you thinking that I need to back to my previous Clover_v2.4k_r4243 version for testing?Now used version 4297

Your kextcache output seems to indicate ACPIBatteryManager.kext is not installed.

Also i wanted to mention the Audio Issue that you are reporting of no sound after wake from sleep:
Make sure you installed CodecCommander.kext and ALCPLUGFIX.

Hi Sniki that will be great if you can. Now my machine working really well, just have this small Audio Issues-no sound after wake from sleep.
PS: I have installed CodecCommander.kext and ALCPLUGFIX( used method from your Guide)
- ALC_Fix - copy alc_fix folder into desktop and open terminal and enter:
Code (Text):
cd desktop/alc_fix
- After you entered the command, open the alc_fix folder on desktop and drag the install.sh and drop in terminal window and then press enter, it will install alc_fix into his proper location.

FYI: You have two PNLF objects in ioreg. config.plist/ACPI/DSDT/Fixes/AddPNLF_1000000 should be removed.
