System halted at a speed of 0.39 GHz
You encountered this problem recently. The laptop, a Dell Latitude E7470 running Windows 10 Core i7 with 8 GB RAM, functions properly when connected to power but slows to 0.39 GHz and freezes when unplugged.
It might be attempting to conserve energy. Have you attempted to optimize your power management options? You could also attempt a stress test to determine if performance improves during intensive use. It appears the device is prioritizing efficiency while preserving battery life. If stress testing doesn’t yield results, reviewing BIOS settings for any accidental activations and considering an RMA might be necessary if it’s defective.
