Laptop Service In Hyderabad
in
this video we're going to be doing acer laptop repair a power Jack repair on a Dell B 130 laptop
first thing I want to do here is check the power adapter cord make sure the
cord is okay a lot of times cords come in and there they could be frayed they
could be bent the pins could be messed up so acer laptop repair in hyderabad I take the voltmeter here and I
set it to 20 volts because typically a laptop power adapters 18 volts and
you're gonna see I take the black tip and acer laptop service I put it on the outside of the pin
and I take the red tip and I put it on the inside of the pin and I'm bending
the cord around here to make sure that it's making a connection you can see it
was 19 volts and that's correct so we know the cord is okay at this point the
outside of the acer laptop service in Hyderabad of the tip of the power diver is usually negative which is black
and the inside is usually positive which is red so that's why I did it that way
now I'm testing to see if I jiggle the cord around in here doesn't actually
make the laptop go on or give it power I want to just determine if it really is laptop repair services Hyderabad
the power jack that's bad or not and I'm bending and bending and still giving it no power now I know the power adapter is good so therefore it's telling me that the jack is bad in sony laptop service the laptop or it could be another motherboard problem so we're gonna open it up and see what's going on in there I usually put sony laptop service in Hyderabad a piece of foam down when I'm working on laptops just say don't scratch the surface when I flip them over that piece of foam is from if you buy a motherboard normal like m ATX motherboard that's usually the piece of foam that comes in the box and they're great for working on laptops in this case now what I want to do is start taking out components like you see I just pulled the battery out now I'm going to pull the RAM out the wireless card out then I'm going to pull the hard drive out as well now the reason I do this is I want to get everything out of Dell laptop service the way see I'm going to be working on the motherboard so anything that's attached to the motherboard or touching the motherboard that's gonna be loose I want to get it out so the first thing I do when I want to do a power Jack repairs I just take all Dell laptop service in Hyderabad the components that I can out of the computer now in this case there's a little flap there you see I lifted that flap up it revealed the heatsink which sits on top of the processor so I could take that off as well sometimes you can't get to the heatsink until you open up the laptop all the way and you see the processor sitting there under it I'm going to pull off the wireless card and I'll tell you a little bit later why it's really important to get the wireless card out of there and lenovo laptop service then one screw pull out that one screw and a CD drive comes out laptops the key to working on laptops is in my opinion to get the motherboard out you want to get the screen and a keyboard off first and the key to getting the screen in lenovo laptop service in Hyderabad the keyboard off is to remove that flap that tab that a piece of plastic that sits right above the keyboard you saw I'll be trying to pry open sometimes it's screwed in from the bottom so I don't know if it's screwed in from the bottom or not in this computer but I'm gonna be taking all the screws out anyway so I might as well pull out all the screws that I that appear to be under that plastic piece just in case there is a screw holding it in then I'm gonna pry it up and just with a screwdriver you'll see a lot of Dells on the right hand side there's a little tab there you hp laptop service put a screwdriver in pulls it right up you gotta get out right under the hinge there that's a good way to do it with a with a flathead screwdriver hp laptop service in Hyderabad and if the end is a little tricky to get off I hit it again with the flat head screwdriver right onto the hinge usually pops right off now don't force that if you have to force it there's probably screws holding it in and then we got two screws holding the keyboard in here once those two screws are out the keyboard should flop right up and what I'm doing is recharging my screwdriver magnetically that's just a magnet that came out of a speaker or something I believe and when I leaves a magnetic charge on my screwdriver which I like to have to pull out lenovo laptop service the pull out screws I just rub it up against that magnet and it recharges the screwdriver now the keyboards gonna flop up and over and you have to pop that ribbon cable off in there codes to keyboard this is the LCD cable after I get the keyboard out I like to get the screen out of the way screens are very delicate part of the computer so let's get it out of lenovo laptop service center in Hyderabad the way so we don't mess it up when we're trying to get to the motherboard so you want to pull out any connect also pull out any connectors that are attached to the motherboard this could be ribbon cables this could be battery connections this could be like trackpad connections which I'm pulling out here you don't want any of those ribbon cables attached to the dell laptop service motherboard so when we pull the top plate off those ribbon cables might rip if they're still attached now in this computer it's a little out of the frame okay we're gonna pull it put it in there's two screws holding the monitor in these screw right into the hinges and dell laptop service center in Hyderabad it keeps the monitor screwed right into the hinges now again on this computer I'm you see I'm kind of recklessly throwing the screws into a pile there's no particular way I'm taking them out because they're all labeled on this particular dome you can tell the size of the screws by the label next to the screw hole which is great and if the computer offers hp laptop service that a lot of Dells do Toshiba does and so now the screens off we're just going to start unscrewing every screw that's holding the top plate on and the bottom plate on you want to get to that motherboard if we can get to the power jack at this point straight on I wouldn't have to do this step but it's the power jack is hidden in between the two the top and bottom cover hp laptop service center in Hyderabad so we have to get them off to get to the power jack now I'm just pulling every screw every place I see a screw hole I'm taking that screw out of the bottom case now I'm not touching any screws on the motherboard itself just the screws that are screwed into the case just gonna give it a check there and make sure I got them all and then make sure I got this got acer laptop service the same ones done on the top and if the case comes apart as easy as that then you know you got them all now we're gonna take a look at the power jack here and see what's going on I'm putting that screwdriver in the power jack hole there to take the pin around now the acer laptop service center in Hyderabad pin inside the power jack may be loosely attached to the motherboard and that's why you're not going to connection now mind you that cord the power adapter cords not plugged in right now to the outlet to the wall so it's not doesn't have power and you'll see that that Center pin the one that's actually pointing in a different direction is loose from the motherboard it's not actually making a connection on the motherboard there so Laptop service in Hyderabad we're gonna have to resolder that point to the motherboard and when we jiggle the power adapter you'll be able to see that pin inside move up and down and not really be soldered strongly to the motherboard and that's what we're going to be fixing here so to get to that point we got to take off take the motherboard out of the machine because laptop repairs we need to get to the top part of the jack and we gotta get to the bottom part of the jack so we can only get to the bottom from here so we're gonna take the motherboard out of the bottom case now I'm unscrewing screws from the motherboard usually on a motherboard if you see that white arrow I'm pointing out there a white arrow will point to laptop repairs in hyderabad
the screws that you need to take out to get the motherboard out there's several other screws in that motherboard and I'm not taking out usually that will guide you that only the ones at the white arrows only the screws that are next to the white arrows are laptop repairing in hyderabad the ones you should have to take out to get the whole motherboard out so you'll see I didn't I didn't need to take the fan off or the PCMCIA slot or a couple other things just because I followed the white arrows and just took those four or five screws out they kept the motherboard in now that the motherboard is out laptop keyboard repair we're gonna operate here we're gonna fix that power jack using a special technique that I do but first since we got the motherboard out laptop keyboard repair in hyderabad we're going to hit it with some compressed air that was time-lapsed right there I actually took it outside I blew all the air out there's a lot of dust that accumulates in that fan and now that you have access to it you might as well take advantage of that and just blow it out okay so I'm taking a look here just inspecting the laptop repair best way to go about attacking this problem and I'm just gonna get some materials here like a soldering iron that's just a typical 15 watt RadioShack soldering iron laptop repair in Hyderabad that I'm using and I'm going to pull some other tools out here I'm going to get a file and the first thing I'm gonna do is I'm going to file off a spot on the motherboard laptop repair services where I can reattach the power Jack
