The CPU shuts down when it consumes excessive power.
The CPU shuts down when it consumes excessive power.
I have an Asus X450JB laptop. The issue is my CPU speed is stuck at 800Mhz, which is way below its designed 2.6GHz. I use ThrottleStop and uncheck the BD_Prochot option so it runs at full speed. But whenever it hits boosted speed, the laptop shuts off without warning. Even when I try to lower it to 1.7Ghz, it still stops. The safest setting is around 1.3Ghz, but that's too low. There’s no overheating—max temperature during gaming was 60°C—and I’m using the recommended power adapter (19V, 4.74A, 90W).
It's unclear if the temperature problem is due to cooling. If stress testing the CPU keeps it under 65°C, maybe a local technician would be better.
