okay so my neighbor brought this computer
she said it wasn't turning on
and had something to do with the power
the first thing I try to do well
check it
and its connected
right now it's connected to the outlet
no lights here
to indicate power
so
I press the power button
nothing happens
not even the lights come on
so my first thought was either the power jack or the power adapter was
messed up
so
I went and got another adapter from ebay
because I didn't had any
other one to test with
so here unplug that
plug the other one which is already plugged into the to the outlet
no lights either, nothing...
I press it, nothing happens
okay
so then... if it's have the power adapter
its gonna be the power Jack
so
now I turn it over
it's already pre...
lets see.. hard to do this with one hand... okay
so I take out first the battery
maybe it's the battery, if something's wrong with the battery
could be messing up with the power... okay
lets turn it over
try to turn it back on... okay
still
no lights.. nothing coming on... its powered in
nothing's happening
so now
I'm going to check the power jack
on this computer it's pretty easy
you open this
and
this comes from the power jack
red: positive black: negative
unplug it
and I get my... my meter here
since for laptops
we know
the power should be 19 volts
when it comes in to the..
the battery... the laptop
since this is a manual ranging meter
I'm going to set it to 20 volts
okay it's gonna be hard to see here
but I'm gonna set it here
okay
so here
I'm gonna put the red test lead
in one of the red wires
the little windows here
you can see two for red..
and two for black
so I'm gonna test that all of them are working
first of all
I'm gonna grab my leads
which I have them here
okay
so.. put the red on one of the windows
and the black on one of the other windows
okay.. so like that
so we said it was 19 volts
we should be getting from the adapter... so we're getting them
so right now I'm testing both
of the end ones
so right now I'm not gonna be showing you the the rest of them
but I'm gonna test them and hopefully they work
so now with that same red one
I test the other window on the black I get the 9.42 volts
now... I switch the red lead
and test with the other two ground ones
the other two windows in there so I get the same result
so it's working, power jack is working
so we're getting power from power... power adapter
through this power jack
to the motherboard... so right now
it's not the power adapter it's not the power jack
so something's going wrong with the motherboard
or something else in the computer
okay so I'm gonna plug this back in
but first I'm gonna un-plug from the power
and I'm going to plug-in this
to the motherboard
and I put it down here so it can close
okay so another thing that could be going wrong
its the memory.. if sometimes when the memory is not good
its not going to let the computer
turn on
I take out one memory... I take out the other one
okay.. so now its overthere
and we have just a: *motherboard *CPU
and no RAM
right now we have the hard drive here if it doesn't work I'm gonna take it out
and we'll see... if it works
so not battery... turn it off
okay
and this is day
the paradigm after I bought which I know it's
work love it here up
computer day lead
okay okay
its their or guess what
getting out late in their and at light
indicated connected to the power so at this point
to and think okay sure if I'm getting at and
LED to turn on and its s it's connected it's getting power
maybe unplugging it in connecting it back in
and taking out the memory did something okay
so let's try it Sepideh trance on maybe it was just a memory
nothing
no response at all
okay so it's not there another powered adapter not the memory
not day power jack okay so start
time to openly computer see what else we can
isolate and see what's wrong with it
okay saw
since I am recording with one hand I already pre
ok opened a the laptop
say such issue for me okay
some when I get a for driver
with a flat tip
and I'll rate today
day all this Chris from the bottom
right now make sure dad
you to cut
this one the one that goes here beaker
that s holding up the plastic on the that top
here day
keyboard effect of
already okay I take it out put it aside
okay and here you normally would see
screw here
here here here our
all ready to come out stock
left this okay at
and this security lock here
left it pull the ribbon
and put us okay
so here you would also see
several screws
which are marked there although sons
I took him out images from plug this
and I to go all day
screws on the bottom and I put 'em a safe place
sonnets don't think that are holding
lead this to play it here
heard yes which is for this
the mouse and a speaker okay
some gonna unplug them this one also
left at like I'd the keyboard I'm gonna take
this whole thing put it aside
okay so this is an inside of day
the computer see
source since
nothing's happening when I press a the power button
my next stop s
take this out put the power back and
my next fight yes I'll I'll
since nothing's happening make day the power switch is broken
and it's not them send a signal to the motherboard
to turn on since we are getting power
from day adapter to the jack which is coming to
motherboard and it's showing us her Ltd that
we're getting power okay
so my next step at I when
ordered apartheid and
take their their of
first should death take it off
and that's their HR
and here which have a replacement said it here
and
its kinda tricky word hand at their
okay now five-day power back a.m.
okay we're getting
LED to come back on let's try
so let's turn press etc happen so no power reader
okay so so far we know
power check's fine para after spying
heart button
it's fine memory it's not affecting
the we don't know if it's okay
or if it's bad but it's not affecting behavior
so at least it's not that that's preventing
from trying on okay
to right now could be
motherboard CPU or what else do we have connected
screen or Dysport
with Chase for two USB okay
let's say let comply with this
and let's trainer
nothing's happening process
nothing's happening
okay
so
it
the screen
target
there
okay so basically right now it's there motherboard
and CPU that's all we have in their connected
we still have the power LED over here
we go here to rate on
not happens okay
so at this point and thinking motherboard spare
or CPU at strike I'm plugging
plugin can
and we get there LED back on
this is still unplugged and waco here
way
we got something why was that
we have power
L here something was discussing a short
with this board and to preventing
a and it was preventing its from trying on
Serena we have
Adam pluck the screen much
everything plug so it's not gonna post because it doesn't have memory does have
pretty much anything okay so
either this or discreet NSA the culprit
let's and plug it
to complain minor
and use both hands because
thats really delicate here
okay plan then okay
sauce if it if it was a
that cable
or to monitor it's not gonna turn on again her
first straight connected here a good day
LED okay
let's go here it press it gay
filtering on we haven't connected
data board to the motherboard and
should be to have power
K
and a that's fine me
and plug it lemme
since one week's other change
data worse pretty much what I
completed it was a *** so I want
ordered another one shots like
seven bucks the one with purple
that someone we had some and
I got that one this one chest blue
here that plastic in their so I know which one switch
and I when I was strong show that shooting this
beginning I am I tested the cable
day continuity test and a
all the cable seemed fine
so it must be the port something mark
set there
and me connected
okay
so it's connected expert power
can and try to
so
rain our getting that it's getting
power and it if on to LED
okay
nothing's happening
me trade-off
to curb the power now I'm gonna put day
memory back and see what happens type
wont stick and to put this once
gotta put 'em angle
first attack an impressive down until you hear dat click
this one as well angle
10 for superb the bottom one then the top
fairly obvious care
and just for
could make sure lets per day battery see what happens but day

a crease basically it wasn't at at
memory was a cane
motherboards K CPU
data was a bar bad Park something
happened today yes we is be bored
which is data on and
right notes we know that
that power button is fine that a
power supply spine and a
or in their right now to have their the keyboard
the trackpad connected some gonna have to be there
like just implied so I can
turned off hopefully that doesn't mess up
hard right and then I'm gonna
plug everything back and output all the screws back in
see if it works I put all disc respect to gather
everything where should go plugged in the
power okay
and its sometimes when you put everything back together
stuff doesn't work get so let see
me yea
we got power
Imagewear
okay saying
said action okay so start normally
and that's because
data had a the keyboard connector
or the trackpad so I had to shut it down by day
what a power button pressing at keeping
pressed until turned off and that's way
gave me that air an
here a
