If I shutdown my PC, then remove the connection to the socket and boot it again, the CPU runs at a minimum possible 480MHz. But if I then reboot it again, this time, without removing the socket, the frequency is normal. If you haven't understood yet:
- Shut my PC.
- Remove the socket connection.
- Reboot after a while.
Result: Frequency of 480MHz(which is the minimum possible) and very slow running and booting.
- Shut down the PC.
- Don't remove the socket.
- Reboot
Result: The frequency is back to normal.
Note that I have a laptop with a battery that doesn't work which needs to be constantly plugged in so that I can do my work.
