Read out laptop temperature how?

Hhomework Monitor shows nothing, only the voltage and load, no temperature

(Lenovo Ideapad 5 14are05 with Ryzen 7 4800u)

Coretemp for the CPU

Right click as administrator

I use a tool called "Core Temp" for this.

Either coretemp or gpuz

Do you have the latest version of Hhomework MOnitor installed? It could be that your CPU is still too new, I know that from Speedfan, for example, that no longer supports my Ryzen 7 3700x, also because it is probably no longer being developed.
