Hi folks,

I have brought HP Pavilion dv6000 laptop USA. I am using this one since last
month. It is found that Battery charger is heating more. Battery charger is
compatible imput 100 - 240 volts and frequency 50 - 60 Hz.

I have found a sticker on battery charger 'REPLACE WITH HP SPARE 402018-001'.
I would like know what is the exact cause of charger heating too much. Does
it effect to the Laptop and battery?

shall I purchare the same configuarion charger in India?

Waiting for earliest suggestions.

Thanks in advance.

the charger heats up because it
is an affect by the physics
of electricity.

your charger is a transformer
and transformers emit much
heat when they convert
ac into dc for electronic
equipment and batteries.

a failing charger will simply
fail to charge your onboard
battery in the laptop.

----------------------

the worldwide concern about
the dangers of heat is due to
the onboard batteries that were
manufactured defectively.

batteries heat up as well, but
the recall are for those defective
batteries that meltdown.

there has been a recall for
these defective batteries however,
it is unclear if you have a
defective battery.


here is more info:

--------------------------

as a word of caution, it might
be a good idea/investment to
get a laptop cooler and if you
are a "male" don't use your
laptop on your laptop.
 
Girl - the statement "'REPLACE WITH HP SPARE 402018-001'. does not refer to
the AC adaptor (charger) but evidently to the battery. The adapter type is
in a sentence above.

Not quite. Rectifiers (diodes) convert AC to DC. Transformers step down
the AC input line voltage (which is nominally 120 VAC) to a much lower
level.

(You're correct in one aspect, however, both emit some heat).
 
i could have elaborated,
include schematics and
provide a multitude of links
related to the science, but
such details are irrelevant
and stupidly convolutes
the objective.
 
I don't need wiki, I already explained that I am an EE. Look that term up.
Note: you know, it's really ok to be wrong about something, and we ALL are,
at times, but what is not so mature is to never admit it.
 
He couldn't possibly admit he was ever wrong. He would lose face. After all,
he spends all his time
erroneously trying to impress us.
