Hello,
I am in search of a schematic or boardview for Lenovo Ideapad Flex 5 14ALC7.
No power and no charging LED with AC Adapter connected. AC Adapter is functioning at 19V, and also tried another Lenovo AC Adapter -- no charging LED still.
There is an active 19V from the USB-C port to the motherboard with AC Adapter connected, so the port is also fine. I am assuming there is a short on one of the power rails, but don't know where to start looking.
Any insight, schematic or boardview would be greatly appreciated.

For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

Hello everyone,
OK, so here is my issue.
This Lenovo B470 motherboard I am troubleshooting died and I identified it is the discrete Nvidia graphics chip that has lost it's ways!
So I removed it and now I am trying to change this motherboard to use UMA graphics, but I am having an issue interpreting the attached diagram. I have a 10K resistor in at the R2013 position and another one at the R2012. R2010 and R2011 are empty.
The motherboard starts, the fan spins but no display. It turns off by itself. I restart it and it does start but stays on...08-12-2024, 02:01 PM -
Hello everybody,
I am asking for the boardview and schematic for a 2023 Lenovo Yoga 7
Manufacturer: Lenovo
Model Name: Yoga 7 14ARB7
Motherboard Part Number: JYG71 / JYG72 NM-E671
Couldn't find them online. If you know where to look, please tell me.
I know this was asked 2.5 years ago by user treewaver, but i'm asking because his post went unanswered.
I am trying to repair a friends laptop with a short on 3V.
Thank you all very much !
