Lenovo 4X20S56713 230W SlimTip ThinkPad Power Adapter
Overview
The Lenovo 4X20S56713 is a 230W AC power adapter fitted with Lenovo's SlimTip connector — the high-output end of Lenovo's ThinkPad charging line. At 230W, this unit is intended for workstation-class ThinkPads with discrete GPU configurations or other high sustained power draws where a standard 65W or 135W adapter would throttle the CPU under load. If your ThinkPad ships with a 230W adapter in the box and that adapter fails or you need a spare for a docking station at a secondary workstation, the 4X20S56713 is the direct replacement. The SlimTip form factor is physically incompatible with older barrel-pin ThinkPads — confirm your system specifies SlimTip before ordering.
Compatibility
This adapter is designed for high-performance ThinkPad systems specifying a 230W SlimTip power supply. The SlimTip connector was introduced across the ThinkPad P-series mobile workstations (P1, P15, P17, P16, and related Gen variants) as well as select high-wattage ThinkPad X1 Extreme configurations. Cross-reference your ThinkPad's original adapter part number or the system's power specification in its Hardware Maintenance Manual before substituting — a 230W adapter will work on any system that accepts SlimTip at lower wattages, but a lower-wattage adapter will not safely sustain a 230W-rated system under full GPU and CPU load. Verify the required wattage from your system's published spec sheet rather than the wattage of the adapter currently in use, as field substitutions with under-rated adapters are common.
