You aren't doing that either. Charging the battery isn't 100% lossless. So you'll actually spend more electricity charging the battery than you'll get out of the battery. So you actually waste electricity while running on battery and save electricity by running the laptop on the mains! > > Thanks for enlightening. I don't know that.

Nope the rule is "run on mains whenever possible". In case you are running solely on mains for a month or more(not really possible with power cuts and all in India) You might have to do a discharge/recharge cycle to calibrate the battery meter reading. > > * Link:- > http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries > (posting > this so that we could get some information over this, even i have to read > this fully yet) Battery university is an excellent resource on how batteries work, and how to make them last etc. For those interested in a summary of sorts, I'd written about it on my website a few years ago http://kingsly.net/kingsly/Random_Chaos/news/item/1191965806/lithium_ion_battery_maintenance_tips.html Kingsly -- --------------------------------------------------------------------------- Kingsly At Users Dot SourceForge Dot Net -- http://kingsly.org/ ---------------------------------------------------------------------------
