Joy! >>High temperatures cause battery issues as well. While laptop running hot , && battery charged @ 100% and power being on AC; is certainly a cause for damage to battery; if am right.
>>running the laptop off battery is obviously inefficient in terms of power consumption (laptop off battery == running without battery && directly thru AC) ? If so, I still could not comprehend the reason behind this. Please explain. =) (IMHO, many laptops do not provide this option of running directly on AC without battery, in the first place) Thanks! /* An interesting topic, laptop battery usage guidelines. :) */ /* My current style is to top the charge up, then let it drain till 20-30%(remaining) and recharge again. Had been advised that completely discharging an Li-Ion battery is not a best practice. This discussion might help us learn the proper way, so that we might adapt it. =) */ On Mon, Apr 20, 2009 at 7:57 AM, joy merwin monteiro <[email protected]>wrote: > > The more you charge/discharge batteries, the faster they get > 'worn' out. bad idea. your experience with the other laptop was > prolly due to the fact that the laptop was running on full perf mode on AC, > and very hot.
