Dealing with my laptop. I believe it had a huge buildup of static electricity. It completely died two days ago, even the charging light wouldn't turn on, and kept making a very low but audible static crinkling sound.
And this morning, I guess electricity was discharged as I saw and heard a spark, followed by the charging light turning on and a slow booting up processing. Thankfully it's still under warranty lol never had anything like this happen.
