Many R5 series users encounter this problem. The CPU runs at the frequency of 0. X after boot, and the computer runs stuck and returns to normal after restart.
as long as it returns to normal use after restart, it will not be a hardware or driver problem. First of all, let’s talk about the solution: turn off the fast start function in power management
reason: the quick start function of win10 has not been perfect, Moreover, it is not very harmonious with the sharp dragon Series CPU. After this function is turned on, the quick start actually realizes a system level sleep state. Rebooting will cause system bugs to lock the CPU to run at low frequency, but it will be released after a complete restart. In fact, this quick start is not fast. In fact, the more correct name should be “quick recovery of last work” 。 In addition to abnormal CPU frequency operation, there is a problem that the system startup time is too long. You can also try to turn off this option to return to normal. Huawei Yu Chengdong: Huawei mate 40 will be released in September, carrying the “out of print” Kirin’s latest 5g chip
