Sorry, I have the option on the E6430 BIOS version A24, so I assume it's the same on the E6230.

No such settings in the BIOS of the E6230. It's just Standard or Express Charge. No custom mode. For a generic/non-Dell battery, I reckon Standard is the desired mode of operation.

You can check your BIOS under Power Management/Primary Battery Charge Configuration. If you have the setting set to Custom, you can have the charge stop at certain %. See if that's what you have it set to. Change it to Adaptive or whatever settings you like.

No such thing as "battery health" for our E6x30 Series and probably most (if not all) Hacks. It's a feature available for some Apple Macs with TB3 ports only. Don't know where you got that it was available on Hackintosh platforms. Your screenshot shows everything you can expect to see in your Energy Saver PrefPane; you won't get anything else. You should, of course, disable those 2 x options to ensure Sleep works at its best on your E6230. If you want more detailed info about your battery, go to SysInfo->Power.

No such limitation in macOS; check your BIOS settings. Note that non-Dell batteries can also behave a little strangely. Injected kexts (from Clover or OC) do not get listed in SysInfo->Software->Extensions, only cached kexts (cached from /S/L/E or /L/E).

@thawri You might have to fully disable the dgpu. Go to the BIOS Boot Option Create a new boot option, call it DVMT or whatever you like Point it to /EFI/Boot/DVMT/Bootx64.efi Save and reboot, press F12 Select the new boot option DVMT or whatever you assign it At the grub shell, select Option 1 for "#1 iGPU-only configuration. No dGPU. " You can restore if with Option 2 if you decide to enable it for Windows. The script is tailored for Precision 7510 / 7710 since they have the same BIOS Test to see if that works, it works for my 7510. Place system to sleep over night by closing lid, woke it up the next day without an issue. It might take a couple of second for screen to show or you could try tapping the ESC key. Darkwake =No and igfxonln=1 are already set on the boot arg. You could try different darkwake value to see if the screen will wakeup faster.
