Lenovo Y40 Battery: Who Should Buy This?
This internal battery is a precision fit for the Lenovo Y40-70 (Type 20347 / 80DR) and Y40-80 (Type 80FA). It is the recommended replacement if your gaming laptop is experiencing:
-
Thermal Instability: The laptop becomes excessively hot near the palm rest, often a sign of a failing internal battery.
-
GPU Throttling: The AMD Radeon R9 M275/M285 graphics card performance drops significantly because the degraded battery cannot provide enough peak current.
-
Sudden Power Loss: The device shuts down instantly when the 90W AC adapter is unplugged, even if the software reports a partial charge.
-
Chassis Pressure: The touchpad is lifting or difficult to click, which is a critical warning that the internal 4-cell battery is swelling and needs immediate removal.
