HP Envy x360 13.3 inch CPU problem

[GarethS1994]

Hi all,

At the moment, i’m experiencing an issue with my HP Envy X360 where the CPU speed is sitting at around 0.40ghz. This has happened since I changed the M2 SSD and installed a clean version of windows onto it. However I suspected that the new M2 SSD wasn’t compatible so I put the original M2 SSD back into the machine and performed a restore using the factory restore image on the SSD that it shipped with. After performing a restore I noticed that the battery was no longer charging but was recognised as being plugged in and the CPU speed is limited to 0.40ghz, anyone got any ideas how to fix?

I read a previous post on here about updating the firmware from Device Manager, this seems to have cured the issue of the battery charging as it now shows it being 100% fully charged whereas before it said it was plugged in but not charging and the battery was only at 27%. I am however still experiencing the lack of CPU power.

If anyone could help me, that would be greatly appreciated.

@GarethS1994 Your suspicion on the SSD not being compatible, was that a hunch or did you go through the maintenance and service guide of your HP device? I respect both, but HP prefers you check the guide before making any hardware changes, to be on a safer side, to obtain the same for you, here's what I'll need:

Hi Richie,

Thanks for the reply. I have tried all of the above that you’ve mentioned. The battery test came back as working normally. What’s interesting is that if I go into the BIOS and load the system defaults by pressing F9 and selecting yes and then save and reboot, the CPU works fine, however when I reboot the machine again, it goes back to 0.40ghz and is really laggy again.

If you could point me in the right direction on how to fix the issue, then that would be great.

@GarethS1994 So, in other words, you've made use of the HP Recovery media to install the OS and yet have these issues, and you've confirmed the SSD is compatible with your product using the maintenance guide? Could you share your product information as requested, earlier?

Meanwhile, please consider using the "Power" settings to step-down from "maximum-performance" to "balanced",

And check if that helps with the lag.

Keep me posted
