I know that it is simpler to pick up the phone & use someone else's brain rather than your own.  All of the information provided below is drawn directly from my experiences as a mobile computer engineer!

 

If your computer will not work, before calling out an engineer, please carry out these few simple checks first:

1) Is the computer plugged into the mains?

2) Is the monitor mains lead plugged either into the computer on directly into the mains?

3) Are you in the middle of a power cut - do the lights work?

4) Has the fuse blown in the mains plug on either the computer or monitor power leads?

7) Has the fuse blown in the multi socket or in its mains plug?

8) Have you spilt tea, coffee or any other liquid on the computer or monitor recently?

9) Is the computer connected to a UPS? (un-interuptable power supply unit - a small box near the PC) If so, is that working?
