The post by Gilles has reminded me ... Does anyone know of a good UPS
solution for the 3000/957?  HP tells me that since the 957 has an internal
battery, the HP PowerTrust UPS and importantly the HP PowerTrust UPS
Monitor software doesn't offer any intelligence for a graceful system
shutdown.  Purchasing the HP UPS (for a 957, anyway), supposedly offers no
particular advantage over a UPS available from any other supplier.  Any
words of wisdom out there on the topic?  TIA.

<<Yes and no. It will provide the necessary protection in the event that
