    Help identifying a chip for Lenovo Slim 7 16IAH7 - schematics needed

    I have this Lenovo Slim 7 16IAH7 notebook that is not booting properly. All voltages are there: 5v, 3.3v, 1.8v but it's still a no-go.

    I spotted this IC chip with markings "6611c" on it. The coil near this chip measures around 200 Ohms which I think is too low. But without the schematics, it's just a guess.

    I wonder if someone has the schematics for this board or perhaps, can help me identify this particular ship. Thanks.

        The motherboard number can't be found anywhere on the board. It has Lenovo FRU: 5821J18076 printed on it.

        SGM6611CYTQV11G is exactly what I was looking for. The coil next to it measures about 150Ohms resistance which I think is too low. By doing voltage injection, only this chip lights up.

          It might be marked on the other side of the board, i think it`s NB6188B-MB-V2 I7-12700H

            ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
            by DynaxSC
            Hi

            I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
            The SPI chip is an Winbond 25Q256JWEQ model (1V8).
            The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
            The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

            I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

            Requesting help identifying chip in Macbook Pro A2485
            by Loki_Fido
            Hi ya folks,

            I have this MacBook Pro A2485 (M1 Pro 2021) which came in for repair.

            It had a shorted SSD power supply chip. Therefore it was stuck at 5V.
            I replaced it and the SSD are fine. No more shorts.

            But The mac still pulls 5V and 200mA. If i leave it alone for 5 mins, the mac manages to receive 20V and 40mA. Of course, which doesnt mean the mac starts after power meter reading 20V.

            But while the mac is stuck at 5V, i checked the board with thermal and found this chip was trying to start. Chip picture is attached.

            Lenovo IdeaPad 3 15IIL05 81WE New Blank Chip - help needed
            by Ardent1
            Hello everyone, I have never flashed a bios before and currently find myself needing to flash a new Winbond W25Q128JVSQ chip without the original bios file.. I have a CH341A programmer and have been able to connect the chip to neo-programmer, but that's about as far as my knowledge takes me so far. When i read the chip the data appeared to be all FF for every entry.
            I do not know the history of the motherboard, only that the old chip was removed because it was dead apparently. When the on button is pressed, the laptop on battery alone just shows a solid white light on the side and same on...

            Help identifying this chip for Yoga 7 16IRL8
            by trepachka
            This chip is shorted thru. Based on what I see, it's either a 3.3V or 5V buck converter, just my guess. The markings on the chip state "S2=AB".

            A photo of the chip is attached.

            Thank you....

            Need help identifying an IC chip on a Bush DAB radio (BD-1801)
            by tyler123456
            Hi,

            Not sure whether anyone can help but I'm trying to identify the IC chip in the photo below.

            I purchased a faulty Bush DAB radio (model # BD-1801) and identified that an IC chip was blown on it. Unfortunately, I couldn't read the manufacturer name / model number of the IC chip.

            I purchased another (working) BD-1801 so that I could open it up to find out the IC details - but the IC chip details are missing (as you can see in the photo.)

            Given the two huge blobs of solder either side of it I'm guessing it regulates power(?)

            Anyone...
