-
Inaccurate Power Reporting: The battery percentage fluctuates wildly or the laptop hibernates unexpectedly at 20–30% charge.
-
AMD Performance Issues: The Ryzen processor is being throttled because the old battery can no longer provide the peak voltage required for "Max Boost" frequencies.
-
Internal Expansion: You notice the laptop's bottom case is no longer flush or the trackpad feels stiff, indicating the internal cells are swelling.
