    Had this computer since August 2008. Put 285 cycles on the battery over 15 months...

    I'm now at 30% capacity according to the Lenovo Power Manager in Windows 7. Defective? Think Lenovo would ship me a replacement? Any advice on what to say to the repair dudes?

    Nope, the battery warranty is only one year.

    Just set power manager to charge below 45% and stop at 50% or whatever gap you choose and leave it pluged on AC all the time. My battery has a cycle count of 108 and its more than 2 years old.

    Some of us (particularly those with ultraportables) actually use our batteries from time to time so those thresholds are a bit too drastic. However, something like start at 60% and start at 95% is probably a good idea to reduce the number of cycles.

    I don't think your battery is defective, but I would say it's done. My x200 Tablet battery has 116 cycles after nearly a year and still holds 97% of design capacity (it was originally 104%). However, in my experience with my T40 the max charge starts to fall off a cliff when you get above 200 cycles (my original T40 battery only held about 15% [but would run past 0%] after 5 years and 500+ cycles). I would suggest you buy a replacement battery if you plan on keeping the x200 for the foreseeable future.

    Interesting... So a cycle is a 0 -> 100% movement?

    It's then safe to assume from your comments that I don't want to start charging right away (i.e., 50-75%), and I don't want to store at 100% (i.e. 50-95%)

    I don't think I could do 45-50%, but the 60-95% ratio makes sense.

    It then suggests that going from 60-95% and back down more often is better than 100 to 0 less often

    Sorry I'm not a notebook snob and dont own an ultraportable. Need to get real work done. I dont work out of Starbucks, McDonalds or the public library. I have a home office and my own company.
