Cj Shaw, you did not tell us how you set the time and date. Download the service manual [http://www.hp.com/ctg/Manual/c00444244.pdf|from here]. Page 42 will tell you how to set it. If it does not maintain the proper time and date, consider changing the RTC (Real Time Clock) battery. Page 81 of the same manual will explain that procedure.
