just tried it, it didnt save my manual profile, just wondering if the battery that comes with it is a dud
(edit) nope, it will not save the time/date or my profile, think i may have a problem returning it now tho, i had to modify the cables slightly to put 4 pin fans into them, thought i ordered 3 pin ones
little update on this, turns out the battery supplied is re-chargeable or something, needed time to power up, took a few days but it now holds time/date/profiles perfect
