CPU not boosting over 1.5 Ghz on ideapad 520S-14IKB (Type 81BL)

2019-04-09, 20:00 PM



I have the above laptop and i have a bit of a strange problem. I can't get the CPU to go over 1,5 or 1,6 GHz no matter what I do with the laptops. The CPU temps are around 65C and the fans are spinning pretty fast however the CPU clock speed doesn't go anywhere near the advertised speed of the Intel I5-8250U https://ark.intel.com/content/www/us/en/ark/products/124967/intel-core-i5-8250u-processor-6m-cache-up-to-3-40-ghz.html


Even if i perform a stress test the CPU load is 100% but the clock speed doesn't go above 1.6GHz, this is with the power plugged in and in best performance option selected.


Can you please advise..


Also can for please advise if the laptop comes with PCI-e  or M.2 slot for storage ?

Hi Krasigogobaba ,


Thanks for reaching out.


We apologize for the late response.

Are you still having issues with the Ideapad 520S?


You can refer to this discussion regarding the low CPU speed: 


According to Platform Specifications, this model supports : M.2 SSD / PCIe 3.0 x 4 for the SSD storage.


Hope this helps with your query.
