Why does windows freeze when changing the type of power supply?
For a laptop, the "power supply" works a little incomprehensibly (Although it may be all about the connector, where to insert the plug from the "BP"). The power goes off and on. Those. the laptop runs on battery, after a minute again from "bp", then again from the battery. And when you change the type of food, it hangs for 3 minutes. It's impossible to work like that. What to do? (I dismantled the laptop to look at the connectors and the plug. Everything seems to be in order with them)

Answer 1

I do not advise you to continue working on this laptop until you fix the problem. And it can freeze due to a change in the energy saving plan, but not as long as yours. I advise you to analyze through the task manager which process slows down the system when switching. And if this is not the case, then the matter is bp.
