Tell Us when computer come off
Thank you for taking the trouble to pass on your concerns. If you are working on a LRSE PC which needs to shut down (for administrative reasons) a shut down warning drops down from the top tool bar 5 minutes before shut down takes place. This should give you time to save your work to a USB or your network space.
