The DOs and DON'Ts of Power Safety?


Hey, I just got a new Dell 600m, and I'm wondering what the new standards are for power safety with a laptop? Should you always have a battery in the laptop when running from the A/C? Or...is this bad for the battery because it messes up its longjevity? Should batteries be run down to the brim before re-charging? etc. etc. Thanks ahead!

Hi.

In short, don't worry about it.

Draining your (almost undoubtedly Li-Ion) battery until it's empty (called deep cycling) will not improve its life, and you won't gain any capacity from doing so. Keeping your battery in while on AC won't make any difference either, as the charging hardware in your laptop will not overcharge, regardless of how long you keep the laptop plugged in.

Most of the 'rituals' people use when dealing with batteries are from the Ni-Cad days, and can be safely ignored on most other cell chemistries.

Deep-cycling a Li-Ion battery once or twice does help to increase runtime due to the "learning" circuitry. Most laptop batteries have "intelligent" batteries nowadays which helps to vastly improve runtimes (not to mention more accurate estimates of "time remaining").
