DELL LATITUDE E6420 PRECOESSOR BEHAVIOR

Hello guys, I own a Dell Latitude E6420 and I run it on Windows 10 pro. I have being having this issue; When I use my laptop while the AC power is connected the processor speeds come down to a constant 0.60Ghz making my laptop slow but when I run it on battery without AC connected the processor speeds shoot up to 3.10 Ghz making it very fast and smooth.My BIOS version is the A23.
