I enjoy my new Inspiron. But I'm still a notebook newbie.
But I know with my Dim 2400, there was no problem having it on all day and
using it some days for maybe 4-8 hours.

Now, I don't intend to just leave the Inspiron on all day (heck, there is
definite heat involved).

But at times I'd like to have the Inspiron on my desk, plugged in, and use
it for say 4-7 hours.

Should that be a problem.

Nope. HDD in Laptops are designed to run for a business day, but not
longer. The MBTF for such a HDD is always calculated for running
about 8 hours a day- not continously. So this shouldn't be any
problem. Besides mine is always runnig, sometimes day and night and
never had any problems in a year and a half..

Can you cite a specific manufacturer's link for such a claim? I've never
heard an MTBF based on 8 on / 16 off.

I leave my Inspirons on 24/7

Please don't blame me, but can't. It was a hazzle to find these
specs anyway. You will be able though to find these specifications
and measurements on every manufacturers site, just take a
deeeeeeeeeeep look at their available links.. For instants use
www.hitachi.com and then make your way through to the travelstar
series and then move on to the sepcs somewhere.. But in fact I could
claim, if you have found that site. Only server hdds are made for
continous run.

Well, until you can cite a link, I'll go on thinking that it isn't true.
I've been involved in PCs since 1981 and have never seen it quoted that way.

Tom,
for how many years have you been running your inspiron laptop harddrive
continuously 24 hours a day?
I also believed you could leave it running and after 2 years of running
my latitude 640 24x7 , i started having weird problems, caused by
overheating with hard drive and possibly internally. if i leave the
laptop spinning for more than 1 day, it often never makes it out of
powersave, but fails with blue screen of death the next morning.

i'm still not sure what's going on with mine, but i have no time to deal
with it. i turn mine off (suspend mode) nightly.
but i tell all my customers that laptops are not desktop replacements
and they should be turned off nightly, not kept running 24x7 unless you
want strange overheat problems.

Tom, I will have to agree with you but do you really think he cares
what you and I think???

I will say, lately I'm seeing some strange specs tho...for ie:
http://tinyurl.com/bhw7b
they give the mtbf and power on hours and on another site I saw
something like time to repair = 30 minutes (can't find that site right
now).

Hence, maybe I'm going to have to back off a bit tho it would be nice
to see his reference for educational purposes.

You will wonder why, but I do. I am right now moving so I am a bit in
a hazzle, BUT I will provide the link if you give me some more time,
say two to three days- if you can be that patient, i can prove it.
BTW also a German magazin called computer & technics also 'claims'
this as a fact.

I run my Inspiron 600m a LOT. On the weekends and holidays it runs for at
least 10 hours per day. On weekdays I run it at least 4 hours per day.

Well, my current Inspirons, not that long, as they're pretty new. My
Thinkpad X40 (which is a tiny 1.8inch drive), a little over a year.

My Inspiron 2100, roughly 2.5 years before I replaced it.

If you're blue screening, that's unlikely to be a hard ware failure, but a
software one.

Except for the machine in our bedroom, all our machines run 24/7. I've seen
nothing that says laptops that are properly made are more likely to fail.

Well, that lists an MTBF, but in a more 'traditional; mode -- no 8 hour
limitations.

Agreed. Thats why I'd like to see his reference to educate myself tho
if it exists, I'll have to figure out why. So it seems we have two
problems here, first finding if this terminology exists and then
explaining what it means.

MTBF 300,000Hours
Power-on hours 2,800Hours
Product life 5 years or 20,000 POH (whatever comes earlier)

Couldn't one take the product life spec as an indication that they design
for ~11 POH per day?

I couldn't really make sense of the second line with the 2800 POH...
