A little more info:
turning off and disconnecting the power for 5 minutes just now and everything was ok, but after re-setting the time & date yesterday, then turning the pc off last night and booting up earlier today, the settings for the T&D are all messed up.
Cheers fellas, So one new battery comming soon
EDIT: not tried cmos jumper as yet - gotta find the mobo manual first hehe.
