Query: Software isn't very good and tech support sucks and can't put laptop on standby.

The instructions that came with it were terrible and tech support is in India and they don't really know what they are talking about. Plus, my laptop is UNABLE to enter standby mode with this adapter plugged in. I have to pull it out each time I set my laptop on standby or the laptop will freeze
