A few questions for consultation

[void285]

Hello, Thanks for your share, I have installed Catalina under the post instruction and run it for a few days. I have a few questions which are not mentioned in the known issues, and not sure if they are related to the dosdude1 method or the kexts or macOS itself, please help, Thank you.

1. The wireless green light never shown, no matter whether I connect to a wlan.
2. I have a 1600x900 LCD, and have copied the DisplayVendorID-* directories, but there are still glitches/lines, not serious, but sometimes shows often and annoying.
3. I have an USB 3.0 NEC Chip ExpressCard, macOS warn there is a power lack problem and the ports can't be used, is there a solution to this?
4. We have power management solution to windows and the battery stops charging when it's 80% full, how can we achieve this under macOS?
5. Airdrop is not available, it's not shown in finder sidebar, even in preferences->sidebar settings, I can find the package in the system, but when I try to open it from spotlight, Macos tells it can't open it because it can't find the the application. It seems some Mac users report this issue sometimes too.
