Hello everyone!
Need help with Asus Vivobook M3502Q, Ryzen 5.
First time working with failed power supply via USB-C ports. no schematics available.
Symptoms:
suddenly turned off and does not turn on,
Upon first observation, turned out both CSD87501 mosfets had unsoldered due to overheating.
Manually charged battery and laptop works on battery
Soldered 2 new CSD87501 on board, but it didn't solve the issue.
there is 3.3V and 1.6V from TPS65994. and it talks to charger, so charger sends 20V, but no load. There is 20V...

Hello everyone! My name is Greg, with computers and any tech since 1993. First interaction with tech was at school: Bulgarian PC [B][URL="https://en.wikipedia.org/wiki/Pravetz_(computer)"]Pravetz[/URL] [/B]8a (on a CM 630 cpu and 256kB of RAM). Grew up on Pentium 2 300MHz computers, 128MB of RAM, 8MB VGA, 1GB HDD. Learned, burned, trashed many components. Still remember installation of windows 95 using 13-15 floppy disks. It was fun and torture. Today I have Ryzen 5600x, B550 aorus elite, 16GB of GSKILL 3600, RX580 8GB, 850W EVGA SuperNOVA 80Plus Gold.Hello everyone! My name is Greg,Leave a comment:
