Lenovo E531 - DSDT Battery Patching Error

2 posts in this topic

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:




Thank you in advance!
