Hi, I managed to install Catalina on E5430, but I am facing a strange problem. If I try to put my laptop to sleep on battery power supply, everything works fine. But if I try to put my laptop to sleep with AC power supply attached, it prepares for sleep, I think it enter the sleep but then it wakes again in a second. Display stay black, but according to less, it is not sleeping. Anyone can try to help me with it please?
