In September, I'll have a couple of long flights. I'll be using my
IBM ThinkPad T41 to catch up on some long delayed FreshPorts
enhancements. Apart from charging whenever I can, I'm afraid I'll
get only about 140-150 minutes from my battery.
Apart from buying a second battery, any ideas?
Turn off wifi and all networking and turn down the screen brightness to
the absolute minimum.
Use the console (and not X), kill all unnecessary daemons. This will
increase the chance the the CPU can enter low consumption mode while you
ponder your code.
That said, I doubt this will buy you much, probably less than half an
hour. You can always try recharging the battery in the toilet using the
shaver socket :)
