I'd be interested to hear how you do this ... but assuming it's true your solution has two parts: 1) the UPS to deal with the "power hiccups". Before you buy, check ports/sysutils to see what models are covered by available software. 2) a more vigorous internal power supply. I have no idea if it's even possible to upgrade HP products short of having HP do it (and maybe not even then). Respectfully, Robert Huff
