I used to manage a small fleet of about 6 XPS laptops at my old job. 3 of them needed motherboard replacements under warranty within a year. People would put them on standby and put them in their bag, then get home and find the laptop had decided to start up of its own volition and overheat to the point it would be searing hot to the touch. The charging would randomly fail or the laptop would go into a boot loop. Not to mention problems with Windows deciding to update 2 minutes before an important meeting (and then naturally the progress bar would get stuck).
