We have had a number of “Out of order” signs on PCs that Library IT know nothing about. If a sign has been there more than 24 hours, report the PC to Library IT again. Another option is to try to use the PC to see if it is faulty. Some of these PCs have nothing wrong with them when we investigate so it may be possible that students are putting these signs on rather than library staff so they can reserve the PC, particularly if it is a hand written sign.
