What's the correct order: Sleep or disconnect dock

[rangor gubbins]

Hi all,
I've got a lenovo laptop from work (can't remember the specs or model off the top of my head). I use it with a dock for connecting to wired network, monitors, power, keyboard, etc., both at home and at work.
I usually put it to sleep at the end of the day but often wonder if it's better to set sleep first or disconnect from the dock first.
Anyone know what is best or if it matters?

thanks. It does seem to work ok either way so you're probably right, it doesn't matter.
