I updated my bios from F26 to F56 a couple of month ago. After this my CPU begin to drastically slowdown when on battery. This doesn't allow me to play high-bitrate video or video editing when I'm not connected to the power.
As my job is video editing and I frequently perform my job in the most different situations where power is not always accessible, this issue makes my pc completely unusable.
After updating the bios t the latest version (F56) I'm not able to reinstall not the original version (F26) neither a more recent ones (F43 or F44 or F45 or F55). Using Win+B restore only the current version F56 and when I try via usbKey the led of the Caps Lock Key start to blink.
I believe the issue is rated to the intel speedstep which is impossible to be disabled.
I reaally need help. Thanks in advance.
