Issue Details

I'm using an NI Thunderbolt device with a laptop and experiencing a slow down of the CPU speed when the laptop is running without a power supply. What can I do?


This behavior can occur on laptops using power throttling. The CPU speed is slowed down to save energy without overheating the CPU. Laptop manufacturers implement this feature in their energy profiles shipped with the laptops or within the BIOS. Contact the laptop manufacturer for detailed information or support on disabling this feature.
