Recently I upgraded my Acer Aspire a515-51g (which have windows 10 installed) to Windows 11 but due to performance issues I switched back to windows 10 but after that my cpu stuck at 400 mhz 
I thought that it was fan issue but my fan is spinning fine and i cleaned that too
I also updated my bios but the problem is not solved
is there anyone know how to solve this issue?

    Hi @ _Cyberbull
    You could try a battery reset, switch off the laptop, disconnect AC adaptor and follow the instructions in the video, leave the laptop to rest for 15 Minutes, reconnect AC adaptor and fully charge the battery before start using again, 3 is the battery reset pinhole in my snip.

    Hi @_Cyberbull,

    Did you play any game on this unit. Is there multiple tab opens in the unit.
