I don't remember if I mentioned it, but I'm leasing a new laptop and its had a few issues... brand new out of the box even.
They replaced the keyboard unit about a month ago and here's the thought process I had last night.
Me: Hmm... the screen hasn't glitched in a while, not even on shut down... maybe them replacing the keyboard fixed the screen issues too, wouldn't that be great!
Me: Time to shut down the totally fixed laptop, I'm glad it's all better.
Laptop, upon shut down: .... .... ... GLITCH! HA HA!
Curse you false sense of security!
