macbook was fine until catalina upgrade. now is starting but after 20 sec is turning off in normal mode or safe mode. i have tried other bios for 820-4924-A, now laptop is working but system is very very slow, that made me think that problem is bios related. Can someone check my bios for problems and hopefully fix it? tnx

Can you post both the BIOS dump that turns off after 20 seconds, and the one that works but is very slow?OpenBoardView — https://github.com/OpenBoardView/OpenBoardView

Try this.
Attached is "820-4924-A slow.BIN" with clean ME and serial number from "820-4924-A catalina problem .bin"
If you have problems, do 3x PRAM reset.Attached FilesOpenBoardView — https://github.com/OpenBoardView/OpenBoardView
