    Dell CPU Throttling while charging (0.46 GHz)

    This is my laptop's issue when it's been bought. When it is plugged in, it is throttled to 0.48 GHz

    , while if it is not charging, it can go up to 2.56 GHz. I tried removing the battery and plugged the charger, but it is still throttled. What can I do? Thank you for the future answers.

    during the charging did you try to run any CPU stress tools to see the difference?

    My computer will lag out when I plug it in. (Don't know if it's the right section)

    Sounds like some software is optimizing when plugged in. This would draw from your CPU causing a frame rate drop. Some programs are designed to only optimize when the laptop is plugged in.

    What security software suit are you running? Can you give a list of non-windows processes when plugged in? Give it about 10 minutes plugged in before gathering the list. This will allow any program optimizations to start and bog the CPU.

    I don't think there is anything wrong with his Laptop. This smells of a software issue.
