Not true, you can run the 130 watt or 150 watt brick no problem at all. Running under powered brick can be a problem. As long as the voltage requirments are met for the laptop it will take what ever current it needs from the supply. (with in the design limits)
thanks. that's what i thought. what he said didn't make any sense so i came here to confirm. especially since the batteries are suppose to have a "smart" chip. i guess i'll just get one off ebay hope it a dell original product and not some after-market crap. any suggestions as far as the 130w or 150w?
