If you were pulling 2 A, that's be the same approximate amount as many 2 x 1U servers. Nate's right -- something is wrong there (this is particularly true if you're in Europe because you'd be pulling less current per device as the voltage is actually 240V RMS based, not 120V RMS based). > What isn't realistic though is that the capacity (both, "design > capacity", as well as "last full capacity") is given as just 279 mAh. > > Should I provide any ACPI dump files? > > I'm not sure whether there are any ACPI BIOS updates available for > that computer. =A0I've always got a hard time finding them on the HP > website. =A0They are telling me everything about Windows device drivers, > Windows 7 upgrades, and other completely uninteresting (to me) items, > but nothing about BIOS/firmware upgrades.
