Oh but I didn't get 4 years from my last one, I got 2 at best! I've considered getting a new battery for it (the old laptop) but I can't bring myself to pay the $100+ that the local Batteries Plus store is charging. I've been toying with the idea of getting one off ebay for $38-$48, but am just leery about the quality.
Only reason I'm still thinking of getting a battery for the old one is cos my dad wants to take it over and use it now that I have a newer (and better) one.
Thanks guys for all your help! It's much appreciated!
