At this time, there is no permanent fix available. We have identified a confirmed trigger: the issue occurs when the AC adapte= r is unplugged or reconnected while the laptop is in suspend mode, causing the C= PU to become limited to approximately 443 MHz after wake. Temporary Workaround: Please advise users to avoid changing the AC power state while the system is sleeping. If the system does enter the reduced 443 MHz state, performing a full system reboot will restore normal CPU performance. I am escalating this to our L2 firmware/ACPI team for deeper investigation.= I will provide an update as soon as we receive their findings. To strengthen the escalation, could you please share the total install base= for the affected model(s) within your fleet? This information will help us prioritize and push for an urgent resolution. ... Good they are at least aware now. Will keep updated. --=20 You may reply to this email to add a comment.
