    Bought the 1705 with up grade to Li-ion 9 cell thinking longer portable time. I use it intensely plugged in & then take it to show customer the work. Well, one year and 9 days later (out of any warrenty) it won't operate on battery power except to hibernate. If I buy another batttery is there a better way to use so battery life is extended?

    Leaving the battery in your laptop while plugged in is a good way to destory your battery. Lithinum ions are meant to be stored with 30-40% power left when not in use. When your battery is in your laptop with the AC plugged in, it's not being used and it's being kept at 100% all the time; this plus whatever heat is generating in your laptop will affect the battery and will allow it to break down.

    This is just ONE out of a few reasons why this happened to your battery. However.. for example.. if your laptop worked fine on battery for like.. lets say 2 hours without the AC plugged in. And then ALL OF A SUDDEN the next day, it wont turn on or hold a charge or only last 10 mins, then yes you could have a way of fixing it as all notebook lithnium ion rechargable batteries are considered "smart" batteries with a chip, circurity inside that regulates everything from charging, to monitoring the temp of the battery to counting how many times it's cycled.. etc, mostly it's designed as a safety thing to prevent lith-ion cells from exploding or over heating and etc and it also has.. Oh.. yea..

    That brings up another point.. one out a few "fuse" in the battery could have been blown due to heat or etc.. another safety thing that'll prevent you from using your battery...

    Well, getting 9 cells on ebay is cheap, but prices can vary. I got two of them for around $58 each. All my 4 batteries are good, each 1.5 years old because I haven't cycled them much.

    If you've been using 1 battery intensely it's no wonder why it's gone bad. Just get 2 from ebay and split their usuage.
