As I said, I jsut did that during the test to have something 
connected... (no laser printer)

Strange, because there was at least a 22" samsung tft and a Logitech 
Soundsystem attached.

                   ^^^^^ TYPO: 25% im sorry!

But why did the same thing happen with nothing but a monitor and a 
soundsystem connected?

Well... maybe you don't mean the same with server than I do.
This is not one of these Sun/HP whatever super servers.
Its a home lan. The server has a BE-2350 CPU with two harddisks.
So, I really, really, really don't think the UPS is overloaded. A friend 
of mine measured the power consomption of the "server" and it was never 
more than 80W. Plus a Monitor connected to the non-battery port. Plus 
an Intel Core2Duo System with a midrange graphics card. 

Maybe the ups is dameged?
But why does it then work with mges crappy psp?
