Detailed description：
Hello good evening, I ask for your help with the following problem.
I have an Asus X512DA laptop that has 20Gb of RAM, with a 1Tb SSD hard drive.
But the problem with the laptop is that it is too slow. I have verified that the CPU or cores are only at 0.40 GHz and not at their maximum speed which is 2.1 GHz.
I have installed the latest drivers from ASUS, also the one from AMD and there is no solution.
If I enter device manager, the Processor drivers, it comes out manufacturer Microsoft (year 2009) and not AMD.
Apart from that, I also tried to modify everything related to the energy plan by changing from an economic plan to a high performance plan from windows but no luck
I will be grateful if you can guide me on how I can improve the performance of the processor.
Thanks a lot.

Can I downgrade bios version 313 to previous version?

Hello smirandac,
Was there any update or modification before this issue occurred?
Maybe a reset is better than downgrade BIOS?
Thank you.

Hello, I reinstalled Windows 10 4 times, and with clean windows is still the problem.
I think the only change I remember is the bios upgrade.
On september and october, I was working very well with this laptop with the same hardware and software

Please kindly send the device to service center.
Our service center can further examine the issue and you may request for BIOS downgrade.
Thank you.
