Re: Lenovo V110-15ISK burned ic
I don`t know.The schematic is available on a few paid sites,and its expensive.Nothing on the free sites yet.You could desolder all the chips and check each one for shorts,get replacement ones and reball the ones that test ok.While they`re removed put some ram in the slot and see if it will work without having to move any straps. EDIT: Do you have a DDR4 test card to check the cpu - https://www.aliexpress.com/item/4000614399711.htmlLast edited by SMDFlea; 10-02-2020, 10:46 AM.Comment

This Yoga 720-15IKB (board LA-E552P) has a burned PU501 IC. As there is no schematic or board view, I am guessing that it is some kind of step-down converter for some rail, maybe 3.3v? I can not read the markings to find a replacement....
