Hi all, I ask for your help in recognizing this M2940A QFN28 chip is damaged on a microsoft surface laptop motherboard, I wanted to know if it is a programmed chip or if it is a voltage stabilizer and therefore easily replaceable with a new one. Thank you all... -
Re: Help Microsoft Surface Laptop 3 flashing logo
Thank you very much for your interest, I apologize because it was up to me to introduce myself first, the motherboard in question is M1098028-008, I hope you can help me, I too was afraid of a short on the card, but I read that the bios is also defective, it does not start the machine and flashes the logo -

Help Microsoft Surface Laptop 3 flashing logo
Hi everyone, as the title suggests, I'm asking for help for useful advice for the Surface laptop 3 1867, when I turn on the logo appears for 3 seconds and then it turns off, it's not a battery problem, because I tested it with another one that works and the charger doesn't work well either, I'm afraid it's a bios problem or even some ram module not working.
Can you tell me what test I can run? I also have basic equipment for desoldering and soldering smd components.
Thanks all in advance -

Hi everyone, let me introduce myself, I'm Morriss, an electronic engineer, and I work at an IT company. In my spare time, I like to buy ipads, macbooks, iphones, and more to repair and then resell them, not for an economic return, which is almost always equal to 0 but for my passion, I met this forum because I was looking for a Microsof Surface motherboard diagram, I hope to lend a hand to someone and receive answers to my questions. Thank you allLeave a comment:
