Before you raise a ticket: five quick checks

Many problems clear up with a few simple checks. Try these first; if they don't help, raise a ticket and tell us what you tried.

1. Restart it. Shut the device down fully, wait 30 seconds and start it again. This fixes more problems than anything else.
2. Check the cables and power. Is everything plugged in at both ends, and switched on at the wall?
3. Is it just you? Ask a colleague whether they have the same problem. If several people do, say so in your ticket: we'll treat it as more urgent.
4. Note the exact error message. Take a screenshot (see How to take a screenshot) or write down the wording.
5. Think about what changed. A new update, a moved desk, a new password? It's often the clue we need.
