⚙️ Fit Notes

• If your laptop’s power jack is the yellow Slim Tip, this adapter will physically fit.
• Match the required wattage printed on your original adapter or on the laptop’s label; using a higher-watt Slim Tip (170W) on lower-watt Slim Tip systems is OK—the system only draws what it needs.
• Systems that require more than 170W may restrict performance if used with a 170W adapter.
