It has sense.

I assume that, unless an absolutely new one, old batteries could last
between 1 hour and 1 h. and a half of average. Which I own are into
these numbers. But about 9 minutes... ejemmm...

Could you be more explicit, please? I don't know if it's due to my
not-very-good English, but I got a bit intrigued with the above.

That's not true, AFAIK, hence my doubts. According with the papers of
IBM-Lenovo for these models (T43), I mean... pdf docs available (on
line) with detailed specifications.

CMOS-> yes
keyboard volume control-> It was that! But sorry, I didn't understand
this point and I have to pay for it... :-P

Everything I can say here is that the fan seemed O.K., big piece, with
some extensions over there (I took some photos when the keyboard was
removed, in prevention someone could be interested in), and I also took
note about the model: Cooler: 26R9066, Fru Fan long M24; 26R9074; Made
in China; Furukawa electric; S060307CN; that's all.

There are enough complains over the Internet about the T43(p) related
with this issue. I just discovered them AFTER it dropped into my hands.

;-) Thanks.

It was discovered. Already commented in my previous post (today).

I didn't get any message about such a issue, AFAIK. I don't get this
point... Hard drive is O.K. 
I understand that what you mean is that someday in the future, when the
drive start to fail, I'd have probably problems to find an unit to
replace it, don't you?
