Hello,
Need help. I‘m working with dead Lenovo V-15 ADA (motherboard GV451&GV551 NM-D151). The laptop is quite new, mfg date 2020-10. Can‘t find any schematics for it. One of the chip LV5028 had a burned spot on it. Before ordering it from China, decided to do some measurements with chip removed. And now I‘m not sure will the new chip solve the problem. There are suspicious readings (chip desoldered):
Pin 5 – 0.4Ohm
Pins 7+8 – 5Ohm
Pins 17+18 – 0.5Ohm
Pins 12+13+14+15 - 4.6Ohm
Found some datasheet of this chip (attached). Are theese readings normal? Or the problem is not only the chip?
