Re: Sony Vaio CPU Throttling and Slowing Down on Battery Power

Hi theAviator, 

How did you upgrade the OS to Windows 10? Did you get the required drivers and software for Windows 10? This is one of the reasons why we do not recommend upgrading the operating system of units that came with Windows Vista and Windows 7. Windows 10will not work well with you laptop. 

Aside from that, your unit VPCF235FAis a non-U.S./Canada model. We have limited information and we do not have the drivers and software for this computer: https://esupport.sony.com/US/p/model-find.pl?DIRECTOR=KBSEARCH&sonymodel=XBR75X940D&region_id=1&template_id=1&sonyregion=US&sonytemplate=1&mdl=VPCF235FA. 

For better assistance with this specific concern, Sony Asia Pacific is actually in a better position respond to this. 

Regards,

Vincent
