Really? Most batteries lose life if repeatedly discharged and recharged.

He's remembering advice for the old NiCad type batteries. Unless
you're using a laptop that's over five years old, his advice is
in fact not appropriate.

That's scary.
I've been using my laptop 24/7 plugged into the mains.
Can you refer me to some documentation which details about it ?

I'm not sure how "significant" the degradation is. I almost never use my
battery, but I leave it in, even when plugged in. It's down to about a 1hr
charge (originally 3) after 2 years. But I've been told best practices
won't give you much more than a 3 year life span, anyway.

I know it is.... Technically. If you have all proper dependencies,
"includes", "dev" packages - it works.
But trying to guess what components I should install to satisfy all
dependencies is a russian roulette.
Commercial software is equipped with clear and intuitive helps and
manuals. Free one is not, what is somewhat obvious. For sure it's a blue

Part of the difficulty is that if you are downloading a TAR file and |
installing that then this is not a TAR file for this distribution, but
rather for all distributions. Getting consistant package names across
all distributions is non-trivial. There are also problems sometimes
when an source package name clashes with another name that is already
in a distribution. So while in a perfect world all names are the same
in the real world oddities are quite likely.

Hi Zbigniew,
this is why Knoppix, and Now Ubuntu was created! They target a different
audience. Debian can be used by many folks, but it is not as end-user,
no-command-line focused as the ones mentioned before. It was not
targeted to an average M$ or Mac user. This need is being filled by
other distros that want to target those users. Free software allow this
natural competition/free market and it gives users the power to make their
own
choices.
cheers,
Kev

My Sony laptop does have little feet at the back for that very
reason, while the Dell 600M does not. The Sony is proped up about
20 degree's but rests on the front bottom. That laptop is about 5
years old got it back in 2001. I must say I am not a big fan of
Sony, but that laptop has been great.
Put it this way my battery life even when new with both batteries
was about 2 hours, with one it was like 45 minutes. It got so bad
that if I would unplug from the mains the battery would only power
the machine for about 4-6 minutes. Now it's down to about 30
sec's, if I unplug and go to another room, I would have to restart.
If you want to read up on battery life this might be of interest to
some of you.
http://www.buchmann.ca/toc.asp
I figure I will see how long this laptop lasts, as it would be cost
prohibitive to invest in new batteries, for such a short working
battery life.

Absolutely. I power off, but I never do a shutdown except when changing

I always suspend instead of shutting down for the same reason . I don't

I would say to do a reboot and possible a file system check once a month
to avoid corruption and unintended loss of data. Other then that, you
don't need to reboot.

Does your laptop get hot under load? My wife has a Pentium M that
burned out two motherboards, when used to crunch RC5-72.
I look at it like this, if a computer is left on it might as well be
doing something, might as well get some use out of it. So I suggest
putting a distributed client on that machine let it help the world,
be it aliens, or dna, or math problems.
Now saying that I have found that some laptops are not desktops, and
heat is a problem, such as my wife's. So if your laptop is prone to
overheating then it might be better to leave it off. As in my
wife's case I had to disable RC5-72, as my warranty is about to
expire and I want it to last a bit longer.
Now I do have a Sony pcg fx215 with an amd duron 800 chip that is on
24/7 crunching RC5-72. It does get hot, but not as hot as my wife's
laptop, she is using a Dell 600M if your curious. the Sony runs on
the mains, the batteries have long since died and have been taken
out. As long as it is able to boot, and crunch, I am happy.

Consumer laptops were not designed to stay that hot for weeks on end.
I use a 12" piece of 2x4 wood to prop up the rear of my never-moves,
always-on work laptop. That gives room to circulate air underneath,

Restarting all services *should* be all that is necessary when
upgrading core libraries. However, it's just as easy, and easier,
to just reboot the box.
There goes your 490 day uptime, though...

That was a real problem with NiCad batteries. Li-Ion don't suffer
nearly as much. Some packs do include logic that tracks charge cycles
and essentially shuts the battery off once a certain limit is reached
whether the battery is physically good or not.
I think this just happened to the battery in my T23. Up to several
days ago it would maintain suspend for about 18 hours. Within the past
24 hours it "died".
