Dear Yvon,
Thanks for replying.
First of all i wanted to test if the unit still wouldn't power down. So,
Via the web Shutdown procedure i powered the unit down......forever

It's completely dead.... Tried everything to power it up again (no disks, replace battery (CR1220) with a new one), but to no afail. Unit is dead.
????? RMA looks like the solution. Looks like de powerunit has broken down.
