1.) Audio crackling. Happens at random and sometimes it doesn't occur for days or weeks and sometimes it'll happen multiple times in one day. I'm not able to reproduce it. I notice it when playing videos via VLC/Chrome/YouTube (I'm sure it'll happen with any audio source). It goes away when I close down the media player or close down the YouTube video and reload etc. Sometimes I have no choice but to reboot the computer to address this issue. 2.) Whenever I close the laptop lid for about 6-8 hours, 95% of the time when I open the lid back up I have to manually reconnect my Wi-Fi. Never used to do this. 3.) Left USB port ejects external hard drives after a certain period of time. The right port is fine. Again, this never used to happen. So, what do you guys think? I was considering a reinstall to see if It's a Windows issue, but haven't got around to it yet. Told Dell about #1 and #2, but they were pretty useless and just told me to reinstall the audio/network drivers, which I did and it didn't fix anything. I still have this laptop covered under warranty so if this is a hardware issue, I could have the component(s) replaced.
