System: Windows 10 Home Battery or AC: both Model: UX325EA Frequency of occurrence: always Reset OS: Screenshot or video: ======================== Detailed description： hello, When i start my laptop the CPU is 90% of the time at a nice high speed on OC and super stable, whether it's on AC or also on battery - in high performance mode, and "performance" from the Asus app, great!! for instance i get 4.05 - 4.35 - 4.50 ghz. BUT when i unplug AC then it drops down noticeably. Even if i am on battery FIRST stable on 4.3ghz then I plug in the AC then it drops. it seems when there is a "change" in power source, there is a drop or something triggers. Why does this happen? During these times, laptop wasn't under pressure or load or anything at that time, so is really cold and cool, no temperature increase (which i know affects the tiny zenbook), so why does the clock drops so much when you change the power source? either on battery TO AC or AC to battery? simply by unplugging or plugging it? all intel power savings are switched off. is that because the machine thinks that during AC operation it might overheat? then if i restart it goes again to high frequency. or just cycling on and off hibernate 2-3 times, which is what i do most often, sometimes it even takes 4 cycles of hibernation, which are fast anyway since it's a very fast laptop. Still is it possible to avoid this? thanks Gabrio
hi Blake, thanks for that Few questions: Did the machine you tested have "Modern Standby" turned on? that's the default setting which i don't like Do you have all power modes available? I do and only if the answer is YES we can do a fair comparison and then i can decide whether or not doing a full reset. so do you have these?: or you only have Asus Recommended? this notebook by default has Modern Standby enabled, which i don't really like for a variety of reasons so i disabled it. This is the flag you need to run: reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0 You can just run regedit as admin and delete PlatformAoAcOverride under HKLM\System\CurrentControlSet\Control\Power again to revert back. Or just as admin in cmd.exe: reg delete "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride many thanks, Gabrio
Hello Gabrio, We tested on clean OS, all default setting. Did not change a thing. Since you have adjust quite a lot of things, let's go back to the beginning and try it one by one. Please kindly reset the device. Thank you.
