HP Compaq nc6320 laptop boots to HP Invent splash screen, then immediately prints "163-Time and Date not set" then cursor just blinks continuously. There is no line to set time and date in BIOS. Reset CMOS battery, put new CMOS battery in nothing works. Tried another HDD, did not work. Will not boot any further than BIOS and error "163-Time and Date not set". Thoughts?
