Cheers Dr, brand new Battery and no charging light on the lap-top, though it does flash with an old duff battery present (whose internal fuse has probably gone).
Its just a matter of knowing which part has gone, there were some other issues with the power supply which I have sorted, but don't have any easy reliable way of testing the charger/laptop data link, the laptop's bios isn't acknowledging the data link, but it still could be either end at fault.
Don't know why Dell included the expense of the data link - they aren't renowned for putting i n surplus hardware.
