As a side note to this. I was reading something recently (from Apple I seem to remember) that its a bad idea to leave your laptop plugged into the mains, when it does not need to be. Apparently it shortens the batteries life. I nearly always have mine plugged in and have not had any battery problems yet, but perhaps I will one day. I thought (perhaps wrongly) that the Lithium batts were a big advance on the older types, perhaps the advance is not so great after all? regards Paul -- Paul Tansley Fashion & Beauty Photography London +44 (0) 7973 669584 http://www.paultansley.com =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
