      Hello, I have this Thinkpad L15 Gen 2 with shorted TPS65994 and also this component near PL040 coil which is also shorted.

      It has "MJ=8D" printed on it and right below it says "L6X". Can someone tell me what this IC chip is?

      Also, if you happen to have the schematics for this board, please post it here.

        Never mind, I was able to find the chip description. It's LV6228CGQUF

          Thread merged with another NM-D271 schematic request thread. Try using the forum search.

        I did try to search for it. If you notice the original poster used "Gen2" vs "Gen 2". That's why his original post didn't show up in my search.

          Did you read SMDFlea's comment carefully?! You're looking for a motherboard schematic, right? Well the motherboard number is NM-D271, and the first result when searching for "NM-D271" is this thread!

        Good afternoon everyone...does anyone have the boardview and schematic for this motherboard?
        LENOVO Thinkpad L14 Gen 2 HL4A0 HL5A0 NM-D271 REV 1.0
        It has 2 bios and I went to remove the IC to rewrite it and they ended up breaking...and now I don't know which chips were there.
        Could someone help me?

          I've already used the search engine...but I only found the datasheet...I would like to know if anyone has the boarview and even photos of the bios ICs...of the 2 bios actually.
