ash7498 Posted November 30, 2020 Share Posted November 30, 2020 (edited) Hello, I'm having a problem where patching my system DSDT with Rehabman's laptop DSDT battery patch: battery_lenovo_E440.txt. The patch is said to support Lenovo E531 laptops. However, patching and compiling my DSDT using this battery patch results in 8 of the same errors: "Object does not exist (\_SB.PCI0.LPCB.EC0.HWAK)". I'm stuck and I can't figure out why this is happening. (Unfortunately, I'm not a programmer). I would really appreciate some help with getting my battery to work. I've uploaded a copy of my system DSDT and Rehabman's battery patch is found here: https://github.com/RehabMan/Laptop-DSDT-Patch/blob/master/battery/battery_Lenovo-E430.txt Thank you in advance!

ash7498 Posted November 30, 2020 Author Share Posted November 30, 2020 Fixed myself. Patching with Rehabman's version MaciASL does the job. Weirdly Opencore suggest against this. Link to comment Share on other sites More sharing options...
