Grid LT 1755 bat indicator

I've scoured the net, even joined the URGrid mail-list, read the Tandy specs closely, but can't find any info as to what the flashing red battery indicator means on my Grid 1755. Even the Grid proponents pass on it. It works but the battery had gone belly-up. I bought a "new" battery and for a while the former orange changed to green but later on changed to the flashing red. It accepts minimal charge but not enough to power the HD when off charge and displays the low-power steady red indicator before dying. If it was simply indicating a dead battery the old one wouldn't display a steady orange. Could it be lack of enough amperage from my adaptor to be able to charge ? I submit myself to the collective knowledge of the list. Lawrence Reply to: lgwalker(a)mts.net Love of the Goddess makes the poet go mad he goes to his death and in death is made wise. Robert Graves
