FW laptop 13 AMD 7840U fan not working under load or at idle, but does spin once on booting.

If I don’t fully seat the fan connector it’ll blow full blast, already had the fan assembly replaced

BIOS 3.09

Anyone have similar issues

If I put the laptop on my lap, it’ll cook my legs in minutes

If the fan runs on full blast when not fully seated then there might be an issue with the RPM sense at the board level. Could be a bad trace, cold solder at the connector, etc. If you have not already start a ticket with support.
