I also noticed in the picture that you don't have your battery in, is that by choice?
Many laptops will auto-switch to a low power mode to conserve the battery. Including your cpu
Change the minimum to 100% and then check cpu-z. If both are at 100%, the processor will not "speedstep" down to lower frequencies.Ok my charger is the issue , tho I dont really know why . I guess I'll have to buy a new 90w charger .
