한성노트북 TFX5135U CPU 동작 속도 0.39GHz

콘트롤 센터(프로그램)에서 조용하게 설정하면 CPU의 성능을 낮춰버려서 굉장히 느리게 동작하는 문제가 있습니다.

조용하지만 성능이 낮아지니 쓰기가 어렵습니다. 

성능으로 변경하면 속도가 올라가는 만큼 팬소음이 있어서 조용한 곳에서 사용하기 난감한 노트북입니다. 

2021년 2월에 접수된 노트북이라서 지금은 프로그램이 개선됐을지는 모르겠습니다만 당시에는 이런 문제가 있었습니다.

 Occasionally, some Samsung or LG laptops have a slow CPU operation at 0.79 GHz or 0.8 GHz. The actual operating speed of the CPU is much faster than that, but when you quietly adjust the system fan speed with the FN setting or the fan speed control program (Samsung Setting Program), the clock may operate very low as shown above.

 I've seen a similar case among some high-end desktop CPUs. I remember being embarrassed because the i9-10900K was operating at 0.8GHz. Even if I change the CPU to i5 product, it is fixed at 0.8GHz, so I visited the AS center of the main board manufacturer and received an inspection. (Not the product I sold, but the repair gun) It's a repair gun) The funny thing is that the center has a normal clock. It was hard to understand why it operated at a low clock. I think I've reset the mainboard (reset), updated the latest bios, and done what I could do as well. I don't know if it was working normally or what the center did when I met the owner. Anyway, the symptoms of low frequency operation have been fixed and you are using it well.

 These are LG laptop products below. It is equipped with an i5-3337U (1.8 GHz by default) CPU. According to the specifications, it will be up to 2.7 GHz. (Click Intel homepage) However, the normal operating speed is 0.79GHz, which is low. I had a hard time because the same value came out after reinstalling Windows 10.

 Task Manager is checking the CPU speed, and sometimes if the CPU is too hot, the CPU may slow down, so the temperature is also being checked at the same time. It's 60 degrees, so the CPU's operating speed has decreased a lot even though it's not that high. (798MHz)

 For LG laptops below, you can change the wind speed by pressing FN+F11. This is a model that works without the OSD program (a program that displays on the screen when you press a special key). Because the fan behavior setting was slow and maintained even after reinstalling the window, it is difficult to know unless you check the CPU speed. Normally, we don't check the CPU's operating speed while reinstalling Windows. When I formatted and reinstalled Windows, it worked too slowly for CPU performance, so when I checked the CPU speed in Task Manager, it was operating at 0.79GHz.

 I was able to adjust the wind speed using the special key of the laptop. Because the fan is turned off, we don't know the relationship between lowering the CPU operating speed or lowering the CPU operating speed to prevent the fan from running, but pressing this button changes the CPU speed and fan speed.

 CPU speed is being restored again. CPU utilization is increasing to 100% as it does not reach the highest specification (2.7 GHz) but rises to 2.49 GHz. (Windows update task is in progress.) My performance is coming out, so I'm responding well to some extent.

 When I woke up from sleep mode, I received a laptop that was very slow in the navigator and was unresponsive when I clicked. When I checked the speed of the CPU, I found that it was operating at 0.79 GHz. Sometimes, a laptop or a desktop...

 It's not a laptop with a good CPU, but can it still be this slow? It's been slow enough. As I checked the speed of the CPU, it is operating at 0.38 GHz at a low speed as shown below.

LG laptop with CPU speed of 0.38GHz

 Before reinstalling Windows, I took down my laptop and replaced it with my test SSD to try booting Windows 10. I replaced it with my SSD and turned on Windows, and the normal CPU speed came out.

 Re-mounting the customer's SSD (when installing Windows, after disconnecting the power of the = hard disk to prevent data corruption) and reinstalling Windows will increase the CPU speed to 0.38 GHz or higher. Although CPU speed varies with CPU utilization, CPU speed is increasing close to a maximum speed of 2.40 GHz when operating 100%. It appears to be caused by a software-specific (Windows or program) problem. Fortunately, it was resolved by reinstalling Windows. The CPU is a Pentium 6405U (2.4 GHz) product.
