The Lenovo ThinkPad W550s 24Wh Original Internal Battery is the essential "Front" power unit for Lenovo's mobile workstation series. This 3-cell lithium-polymer battery works in tandem with the external rear battery as part of the Lenovo Power Bridge system, providing the stable 11.4V output required for the W550s workstation's high-performance Intel Core i7 processors and NVIDIA Quadro graphics.
At KSh 8,038, this 24Wh unit is the certified original replacement for part numbers 45N1110, 45N1111, 45N1112, and 45N1113. It is engineered with high-density cells to fit the internal cavity of the W550s chassis, enabling "Hot Swapping" of the external battery without needing to shut down the laptop.
Lenovo ThinkPad W550s Internal Battery: Who Should Buy This?
This internal battery is the essential fit for ThinkPad W550s users in Kenya experiencing:
-
Sudden Shutdowns: The laptop turns off instantly when the external battery is removed or fails, indicating the internal "bridge" battery is dead.
-
Charging Issues: Windows reports "Battery 1: Not present" or "Plugged in, not charging" for the internal unit.
-
Poor Battery Health: Lenovo Vantage reports the internal battery has "Poor" status or has exceeded its maximum cycle count.
-
Swelling/Bulging: The palm rest area or trackpad feels raised or stiff, a critical sign of a swelling internal battery that requires immediate replacement to avoid motherboard damage.
