Hardware, Embedded Systems San Jose-based sent us one of their best-selling laptops, the LC2430. We've used it for more than a month with four different distributions and here's what we think about it.

if i had a nickel for every time i recharged

the aforementioned links states (for nicads only) "Discharge to 1V/cell every 3 months to prevent memory. Do not discharge before each charge" so there it is folks, NiCads do develop memory, but deep-cycling them over and over is not good. they need periodic moderate-cycling only. but NiCads are going the way of the dodo anyway.

I've heard a number EE's chime in on the subject of so-called "battery memory" and I think that, in the final analysis, it's just an urban legend that was perpetuated early on by some misguided marketdroids.

i'm not an EE, but i've had loads of college physics. i do believe nicads have a memory, since most battery manufacturers tell us this. there are some urban legends in EE. for instance, it's compression not harmonic distortion that blows tweeters when you clip an amp. and maybe magnetic screwdrivers are ok near hard drives, but it's an old-school rule of not using those tools near high-voltage i.e. promotes bad habits. most rules aren't universally applicable, they are situation-dependent. the problem is then -- language is sufficiently bulky that you can't convey every single caveat in a finite set of words.
