[piggynose]

I have got a Packard bell dot s laptop, or should i call it a netbook. I´ve had it 18months, and the battery needs changing. I have had a look at prices, which seem to vary from 20 to 85 quid. plus do i go for one with 4 cells or 6 cells?
thanx in advance

Go for 6 cells and the highest mAh rating (if they differ)
