    Help identify IC on MSI laptop

    Hi guys,

    Need help identifying this SMD IC on an MSI laptop.
    The only marking which makes sense is 3518. But there's nothing on the internet about it.
    It's located right next to the USB ports.
    Can anyone help me out ?

        Thanks for the replies. But the white marking around it suggests it's not QFN, more like a 12pin IC (6pins on top, and 6 pins on the bottom). Where the white Notch on the left indicates Pin 1 is on that side.

        I'll try remove the IC when I get a chance. Probably Tuesday due to Easter Weekend & Bank Holiday Monday.

          Also, sw3518 has more pins than what's on the board.

            First row of the IC is barely readable. Please write the marking code out in Full.

            Other than i am curious too what turns out when you finally remove that IC.

                Agree with this one. Good find. Just want to add to pay attention get the 01 variant (Auto-Restart)

                    MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
                    by RdeveLabs
                    To all the members here...

                    Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

                    So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...

                    Please help to identify the components on Surface Laptop GO3, model 2013, i5-1230U
                    by User2025
                    Hi,

                    I am working on a Surface Laptop GO 3, which is the new release 2024 with a i5-1230U processor. Originally, it had a 256GB SSD, then the owner attempted to upgrade it to 1TB SSD by himself. "Surprisingly", it did not boot afterwards, then changed back to the original SSD, did not boot either.

                    It turned out to be that just a couple of components had been knocked off when the owner was trying to get off the SSD cover with his beloved screw driver.

                    I do not have another board of same model. Although I have a Laptop Go 2, the layout of that bit...
