I have an Inspiron 9400 and things appear to be working well. However, I just noticed the battery status light which normally is steady green when on ac power is blinking 4 times orange and one green, pauses and then starts over. I don't recall seeing that before. The manual talks about shutdown warning when you are on battery supply, but this is when it is on ac power. It would appear to be a warning, but I can't find any reference. This occurs regardless of whether the computer is on or off.
