I just bought a used Dell Battery Slice (UJ499, KJ320, or TU211) for my Dell Precision M6800.
When I attach it to the laptop the battery status led just flashes amber.
When I plus a power supply into the socket on the battery pack the LED turns on white to indicate charging, then after about ten seconds it flashes amber, then white, then continually flashes amber.
Does anyone know what these fault codes really mean? Is there any reasonable chane that replacing the Lithium cells will fix this or is it locked into a dead state?
