Hello all! I am new to all this so please bare with me.
I have a lenovo carbon x1 7th gen a friend gave me. It hung and he turned it off to restart. After shutting down it had no power/no charge light. I pulled it apart and found a blown cap on what appears to be the main power rail. I cleaned up the area and tested, but no luck. Everything around the coils/inductors comes up shorted (caps, ic pins etc) to ground. I also have a few caps here and there that seem to be shorted to ground. I removed an IC and a cap to see if the short would go away but no luck. (i removed the ic because freeze spray showed it was getting hot and I thought this might be the cause.)
Does anyone have a boardview for this? I can't seem to come up with one anywhere. I believe this particular model was a Costco only unit.
Physical inspection of the board looks good otherwise. As stated I am new to all this and not sure what to check next. I'd really like to fix this laptop as I need one and funds are tight right now as I was laid off for CV19 related reasons.
Let me know if any clarification is needed. As stated I am totally new to this level of diagnostics so you may have to dumb it down for me. I am however very eager to learn more.
