Re: [Phys-l] computers



Other recent devices's instructions suggest full capacity of their batteries is not reached until fully cycled several times. I suspect this may even be true of Pb-acid cells also. *

I often pack my PB in it's case w/o shut down. When I begin using it, it is not even warm. Turning off the display's illumination reduces the temp. considerably. I dropped my second PB while it was "running". The result was broken hinges, nothing else. This is certainly an improvement over the mini-computer Physics (UCSC) had in the mid 80's. Huge sign: Do not bump the computer.

* I suspect this is the explanation for much improved mileage of my Prius after a few weeks; thank you.

bc, who has not enabled auto update.

This (battery use) is the same advice I have been given by my neighborhood
Mac man, especially the first few cycles. John's advice may be more
up-to-date, but I have followed the advice. He also said shut down, or at
least sleep, when not using for a long time (overnight). Be sure to shut
down a laptop before packing it in a case.

I worry about the useless use of energy by leaving computers on all the
time. I am willing to power on when arriving in the morning and waiting
while I am settling in for the day.

Interesting!

My tech guy also said it is best to charge the battery to 100%, unplug,
use the computer, and let the battery drain to nearly 0%, then recharge
again. He said this will extend the battery lifetime, rather than to just
keep the plug in all the time, or to not let the battery completely drain
before recharging.

Thoughts?
