Replied on your other post, next time please try to consolidate to a single post especially since it is about the same laptop.
Whilst using my XPS 13 (9300) after closing the laptop (moving rooms in home) lip and reopening it. Any applications I had open no longer perform the same. For example; Youtube will fail to play video, Google links won't open, Music won't play on Spotify. Even reloading the application has zero effect. Therefore, my only solution is restarting the laptop. A lot of action in order to get the laptop working how it should after carrying out a basic exercise (closing the laptop lid).  A ridiculous error for a laptop which has an asking price of £1500+
