CPU issue
Hello, I'm dealing with a laptop that has an Intel i5-5200U and recently encountered some unusual issues. It seems like the CPU clock suddenly drops to very low speeds—like 0.38 or 0.78 GHz—and doesn't recover. This happens unexpectedly while gaming or streaming, but it can last for days without problems before resuming normally after a restart. The system specs are: i5-5200U, NVIDIA 920M, 2 GB RAM, Intel HD 5000, dual GPUs, 12 GB RAM, and a 248 GB SSD.
Is it powered by battery or wall outlet? I experienced a problem similar to this when working with battery—clock speeds fluctuated from 3Ghz to 0.8Ghz and back, then again. Eventually, I installed Intel XTU and adjusted some settings so the system could consistently run at higher frequencies. Make sure to also set Windows profiles to high power.
You can also configure the minimum CPU state to 100 and set the CPU speed to run continuously at full capacity. Make sure you install the most recent Windows updates.
I've tried everything you mentioned earlier, but it's still running on battery power. I have some solid IT knowledge and straightforward fixes, yet it seems like these won't work. Thanks for your help.
It seems you're facing challenges with your laptop's performance. You mentioned not being able to tweak voltages or frequencies directly through the BIOS. While tools like Torque exist, I don't personally endorse them. Have you tried using HWmonitor? You might think it's about heat, but perhaps the thermal paste isn't applied properly. The system could be restricting the CPU speed for some reason. A CPU crashing is uncommon.
Using a laptop usually means reaching out to the maker directly or sending it for repair. Laptops can be quite challenging at times. From what I understand, your issue might be connected to temperature or power problems. However, I’m still not entirely confident.
Consider trying ThrottleStop. It's the sole free tool that lets you disable the BD PROCHOT feature. When a sensor fails, it transmits throttling commands straight to your CPU. Your processor interprets this as overheating. Even if the temperature is normal, it will initiate thermal throttling and settle at 400 MHz or 800 MHz based on the model. Disabling these signals lets your CPU operate at full capacity. Before adjusting settings, check the Limit Reasons window—it'll reveal if BD PROCHOT is responsible for throttling. Search online for this issue; it's a frequent concern across various Intel laptops. With some knowledge, you're already aware of it! You can also use ThrottleStop to limit voltage and boost performance.
