Quite enthusiastic about Cospaces, I have developed the bulk of my Digital Technology course for Yr 7/8 around it. This year we have a new classroom space and the laptops are only charged at the end of the day. They are HP Elitebooks and new this year, but they only hold the battery charge for 3-4 hours when used predominantly with Cospaces. They are used with 3 different schools and classes in a day and we have four hours of class before lunch. Do you have any suggestions for reducing the battery drain? Thank you.
