AMD PSP technology

Hi guys

I am interested to know how can i check if i have AMD PSP installed on my Laptop and which version do i have?

I am afraid for the security on the machine that i am using.Its HP laptop with AMD A10 5745M CPU and dedicated GPU(R7 M260 Topaz XT).Compared to the another Acer laptop with Beema E26110 the HP laptop has LED indicators for the ethernet.

Now quite often my ethernet LED would remain active even after my Laptop has been turned OFF.Now sometimes it would happen when i turn OFF the Laptop(initiate through Ubuntu interface)my screen just goes into loading for the power OFF and remains there,and then if i would turn OFF laptop on the power button(by holding it until laptop turns OFF),my LED for the ehternet would turn OFF,only in this case,otherwise it would still remain ON.

Now i already tried fixing this with newer BIOS firmware,but this did not worked.Also worth of mentioning both laptops have really low number of options in their BIOS and on A10 version overclocking is not available at all,as there are no GUI tool for GNU/linux and options inside BIOS are limited.

So maybe you see my previous thread where i was interested in ARM,but when it comes to purchasing old Libreboot laptops such as X200 ,i am really skeptical as eroding is a problem and i do not like to buy used stuff .

Regards
