You say… sometimes you have to ask staff to turn PC monitors on in booths and rooms

We say…
We don’t ever turn them off, however, some of the monitors have power saving functions which mean that if nobody has used the screen for a while the monitor turns itself onto standby (this tends to be an issue in the mornings as we are not as busy overnight) there is a button behind the monitors which turns the screens back on.
Ideally, as the power button is in an awkward position due to the wall mounting, we recommend asking the help point to assist with this.
For meeting rooms though, the button is accessible and is normally at the back bottom corner of the screen.
Also we’re working continually with IT to resovle any PC issues before they affect you.
