Hi, I've bought a P6661 on 27th December 2016. For about 2 months, all was ok, then in early March I started getting freezes when the laptop was running on battery. The computer would simply freeze, the screen would stay on. System would be halted and completely unresponsive. After hard restart I look into Event Viewer and find 4 entries for "The speed of processor X in group Y is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report." respective to all 4 cores. This freeze is random and occurs for example when working with 3DS Max or within Unreal Engine. It never happens when on battery or when simply on without any graphical load. Today for example I could play 30 mins of Witcher 3 but within 2 mins of Unreal Engine, the freeze would occur. I'm running latest NVIDIA drivers, I've updated BIOS to the 19.10.2016 version too. No change. Would you be able to give me some advice?
