6] Disable C-state in your system BIOS

Each CPU has many power modes that are collectively called C-states. By default, the C-states are on. These are the power-saving states which help save energy when the CPU is left idle. The idea behind introducing C-states to computers was to cut clock signals and power from the CPU’s idle units. The C-states start with C0, which is the normal operating mode of the CPU. At C0 state, the CPU is completely turned on and is 100% active. With the increase in C number, the CPU sleeps deeper. When more signals are turned off, the CPU takes more time to return to the C0 state.

According to the users who received this error by connecting the Lenovo Thunderbolt Dock with the Lenovo laptop, disabling the C State from BIOS fixed the issue. If you have a computer of another brand, you can give this method a try. If it doesn’t work, we suggest you revert the changes in BIOS.
