Hello all,
I've been for some time now trying to troubleshoot this Clevo W650SC laptop motherboard. It has no power, no charging lights, nothing. Now please bear in mind I don't have much experience with this stuff, so looking for some info online I decided to search for shorts.
Luckily I've managed to find this
service manual.
VIN is not shorted and I'm reasonably convinced of a short on VDD3. I've desoldered most mosfets, disconnected coils and removed some caps without success in pinpointing the faulty component. The lowest resistance I could find was near ME and BIOS ROM (U27, U28), but desoldering these didn't fix the short.
Any ideas on how to go forward ? Thanks in advance !
