Sorry for my bad English. This might be a memory problem. I have a ASUS VivoBook16(I can’t find it on ifixit,so it might be China special?) and I ran the same problem yesterday. I accidentally poured my coffee on the computer.after I cleaned it up,I found the computer didn’t turn on,and the charging light blinks. After looking for some videos on BiliBili (a Chinese video platform),I found a Lenovo laptop owner says it might be a memory problem. After cleaning the socket and pins, system posted and successfully booted into windows Hopefully this will help you. Awmc233
