As the title says i need help finding a replacement for a chip i accidently shorted while preforming a thermal paste replacement on my laptop. A fan screw fell onto it and that is what caused the problem; i found it was the chip that is causing the problem because it would overheat and produce a burning smell.

My laptops modle is the Acer nitro 5 an515-58-59XZ and here are some photos i took of the effected area:

Edit: the chip is labbled RW=9k 444 i know it isn't easy to see in the photos that is why i am saying this now lol

[Edited the topic title to include model number]

    Not all the captions that you have posted in your post are showing, try again, also, its impossible to read what is written on the mosfet chip with your huge size caption that you have. Try and reduce the caption by at least 50% with windows Photo and also try and read the numbers and letters on the mosfet chip as that is how you should look the chip up on the web which will be your best way to find this mosfet chip or enquire at www.electronicloop.de as they have a good range of quality chips for computers available as long as you give them the mosfet exact chip number that is written on that chip. Good luck and hope this helps you out.

    I haven't put a caption on the a images?

    But the labbleing on the chip as i said above is RW=9k 444 nothing comes up when i search for it on the web that is why i am asking here to see if anyone knows a replacment part (it doesn't have to be original) also i was told that it was a power stepdown chip .

    @Lmar

    Can you take a picture of the whole motherboard and mark the chip location?

    Even if you get the RW=9k 444 chip you will need a microscope and all the proper tools to solder this chip properly onto the mobo, don't attempt to do this if you don't have these tools as you will cause even more damage, aslo this chip could be welded onto the mobo and could have mobo damaged traces which is another issue that needs to be tackled and fixed. Get an experienced technician that specializes and has all the tools to fix this sort of a problem.

    See Sorin Electronics as he knows where to get all these chips, I don't know where you are situated, but he is just outside London England, as he has a channel on YouTube and this guy is a specialist and a great technician that fixed burned mobos which their chips are have welded themselves onto the mobo and he knows what he is doing, as that is the sort of technician that you need to take your mobo to so it can be fixed properly, otherwise you are wasting your time..

    Hello, @StevenGen

    Unfourtantly i am situated in Germany so it would be a bit hard to contact SorinElectronics.

    However, I have spoke to multipule technicaians about this issue they have told me that all i need is a new chip and it would be fixed because it can be replaced with by simpily unsoldering it and putting another in its place.

    I couldn't find a fit replacement yet, however i have come across the MAX7311ATG+ which seems to be a posible replacement but i am still looking into it as we speek.

    Regarding @AnhEZ28's request here is a picture of the whole board:

    Ignore the circule around the vram that was something else (I am just reusing the image(this image is after the short circute))

    The PU301 is a 3V power rail chip. Part number is SY8388BRHC. Check the surrounding capacitors for shorts also.

    @AnhEZ28 The surrounding capacitors are okay, but the RW-9k 444 chip (PU301) has 24 pins from what i can see but the SY8388BRHC has 16, why is that?

    I think I got the wrong board schematic. What is your motherboard part number? Check on the other side of the motherboard.

    @AnhEZ28

    I couldn't find the board number nor the schematic for my specific model online that is kind of where i am stuck right now.

    (The board number isn't on the board somehow i searched on the whole board and couldn't find it)

    That is the connector labeled to the motherboard side.

    Can you take a picture of the whole motherboard? Top and the bottom side.

    It should be somewhere around the SSD area or under the silver shielding at the bottom side. Or under the thermal pad near the RAM slots. Take out each thermal pad to reveal.

    Lmar just some additional advice, as this site that I’ve given you at; www.electronicloop.de is in Germany and Sorin uses them for allot of his chip purchases so contact them and ask their advice for that chip, as I’m sure that they will be able to help you. Good luck and I hope you sort this issue out.
