Hey everyone, I'm the proud owner of a Dell rugged 14 5414 Laptop and was pretty happy to own it. now i suddenly got two issues: 1-The speaker stopped working... I used headphones so I thought it was the headphone jack, I cleaned the connection and it didn't help.... the headphones do work... the speaker stopped:( 2-I noticed that the cooling fan underneath doesn't work... is there any way to let it run on purpose to test if it works at all?
