From: "Dwight K. Elvey" <dwight.elvey(a)amd.com> Hi Al I was hoping you might have the answer for this one. I just got a HP2113E. I've not been able to use it because it wants to have a battery connected. There is suppose to be a battery simulator plug for these. I'm looking for any schematic or part information for this item? Do you have this or any schematics for the supply. It seems to be the same as the 21MXX type B supply that is in the CE manual on your web page? Thanks Dwight
