La luciérnaga pequeña no quería salir por las noches con sus padres y amigos porque pensaba que la luna brillaba más que ella. Su abuela la convenció de salir explicándole que la luna no siempre brilla y que aunque sea pequeña, la luz de la luciérnaga es constante. Al ver a los demás brillando, la luciérnaga comprendió que cada cual debe brillar con su propia luz, sin compararse con el sol o la luna.

The document discusses laptop components including AC/DC power adapters, batteries, motherboards, keyboards, processors, cooling fans, and CMOS batteries. It provides instructions on testing and replacing these components if faulty. The main points are that power adapters must match the laptop's voltage/polarity, batteries can be tested but usually must be replaced if faulty, and motherboard or keyboard failures may require replacing the entire component.
The document discusses power supplies and the differences between IDE and SATA interfaces. It provides details on how power supplies work, converting alternating current to direct current and regulating voltage. While SATA allows higher bandwidths than IDE, a SATA hard drive is not necessarily faster as most drives cannot sustain speeds above IDE's maximum throughput. The key difference is that SATA uses fewer pins and a simpler serial interface compared to the older parallel IDE interface.

Here an electronic circuit breaker is designed which is based on the current sensing across a series element typically a CT (current Transformer). The current sensed which is compared against the preset value proportional to the voltage by comparator which is inbuilt in arduino to generate an output that drives a relay through a MOSFET to trip the load very fastly.
The concept of electronic circuit breaker came into focus realizing that the conventional circuit breakers such as MCBs take longer time to trip.
The steadily increasing population has more demand and consumption of electric energy in the market as raised and that of equipment’s used like electrical and electronics are also costlier
So to protect the electrical system from overload or short circuit here is one possibility, which is by ultrafast acting electronic circuit breaker
The electronic circuit breaker is based on the voltage drop across a series element proportional to the load current, typically a low -value resistor.

Similar to Why hp smart adapter still can not work (20)
The Indian government has been working over the past few years to include elements of ITS in the transport sector. This standard ensures the optimal operation of the current transport infrastructure. It also increases the efficiency, safety, comfort, and quality of the system. That is why the government created the AIS-140 standard. Compliance with this standard means all vehicles used for public transit must have panic buttons and vehicle tracking modules installed. Nevertheless, in future in the standard protocol of AIS-140 you can expect fare collection and CCTV capabilities.

1. Why
Laptop
HP
Smart
Adapter
Still
Can
Not
Work
After
Replacing
Battery
And
Adapter?
Laptop
ac
adapter
can
not
charge
for
your
laptop
to
perform?
Many
friend
around
me
encountered
this
problem.
"I’ve
replaced
both
battery
and
AC
Adapter,
but
why
it
still
could
not
charge?”
Maybe
you
are
one
of
those
who
are
complaining.
Broken
battery
and
AC
adapter
are
the
most
common
reason
while
there
is
another
one
that
most
people
would
neglect
:
Loose
or
Broken
DC
Power
Jack.
Symptoms
of
a
broken
DC
power
jack:
l The
laptop
only
operates
when
you
hold
the
DC
power
plug
in
a
certain
direction
(DC
jack
is
broken
or
loose).
l The
laptop
only
runs
on
battery
power
(no
power
is
getting
through
the
DC
jack).
l The
laptop
gets
no
power
at
all.
l The
laptop
will
not
charge
the
battery.
l The
laptop
switches
from
AC
power
to
battery
power
intermittently
due
to
a
loose
or
broken
power
jack.
l The
laptop
suddenly
shuts
off.
l The
DC
jack
may
feel
loose.
l Parks
come
out
of
the
back
of
the
laptop
when
you
insert
the
power
plug
into
the
DC
jack.
How
some
repair
centers
handle
DC
jack
repair:
Most
service
centers
don’t
want
to
deal
with
this
problem
by
attempting
to
repair
the
DC
jack.
Many,
including
the
large
nationwide
stores
and
the
laptop’s
manufacturer,
will
either
tell
you
the
machine
is
not
repairable
or
that
they
will
need
to
replace
the
motherboard.
These
quotes
usually
run
from
$250
to
as
much
as
$800.
They
choose
to
ignore
the
fact
that
a
broken
DC
power
jack
can
be
repaired
without
a
motherboard
replacement
because
they
are
not
equipped
with
the
tools
or
training
to
do
DC
power
jack
repair
on
your
laptop.
How
a
DC
jack
breaks:
l The
HP
Smart
Adapter
jack
on
most
models
of
laptops
do
not
have
enough
reinforcement
within
the
structure
of
the
casing
and
motherboard
to
handle
the
stress
caused
by
movement
of
the
power
plug.
l Some
DC
jacks
simply
fail
under
normal
operation
of
your
computer.
After
a
year
or
two
of
usage,
parts
just
come
loose
on
certain
models.
l Sometimes
the
laptop
gets
dropped
and
the
plug
jerks
the
DC
jack
loose.
l People,
pets
and
vacuum
cleaners
trip
over
laptop
power
cords
and
break
the
DC
power
jack.
l The
laptop
is
moved
around
a
lot.
After
the
DC
jack
is
moved
back
and
forth
enough
times,
it
comes
loose.
l In
some
cases
the
DC
jack
was
not
soldered
onto
the
motherboard
well
by
the
manufacturer.
