Detailed description:

Hello,

I have a problem with my laptop. The CPU gets stuck 2-3 times per day at 0.38Ghz. It helps when I close the lid (when I put my laptop to sleep) and open it again - after that CPU frequency is back to normal. I believe it happens only on a battery. My laptop is running on the last available BIOS 309.

I'm not sure but I think I didn't have that problem on BIOS 307 (at least not that often).

It is possible to downgrade the BIOS to 307? Or do you have any other solution to this issue?

  • Hi there,

    May I know what program or APP were you using when the issue occurred? What is the % of the battery?

    Can you check if the device is set to power saving mode ?

    Thank you.

    Hello,

    Usually, it happens during web browsing (I often see this when I close fullscreen video) I'm using Firefox as my primary browser. Yesterday this issue appeared when I had a 40% battery.

    The laptop was on Better battery Power Mode and the battery saver was off.

    I had this problem for last weeks almost everyday but between 26th June and 2nd July it occurred only one time.

    Hello,

    It happed again today but this time with AC Adapter connected. Battery charged to 80% (in MyAsus I set 80% as the maximum)

    Any Advice?

  • Hi there,

    Have you tried to enter BIOS and load default setting again?

    Thank you.

    Hi,

    I tried it but it didn't help. Today it happened again, this time when I was watching a movie using VLC (VLC media player) When it happened I had about 68% battery.

  • Hello PorteX,

    I have reported this case and asked for more advice about this.

    Thank you.

    Thanks,

    I not sure if this will help find the root cause, but I have found I can unstuck the CPU just by disconnecting the AC adapter (when AC adapter is connected) or by connecting AC Adapter (when the laptop is running on battery).

  • Hello PorteX,

    Yeah, that's one way to solve this kind of issue.

    Thank you so much for the information.

  • Hello PorteX,

    May I know which fan mode did you set in MyASUS ?

    Thank you.
