The seller said "The display fades away a few seconds after turning it on." He was right. Opening the battery compartment to see if they were dead, instead I found the same three 12V batteries you did. Popped in the right ones and all was well. HP made them tough at one time, so give yours a try... ~Mark Remember kids, "In a democracy, you get the government you deserve." |
