Before ordering this replacement ac adapter, you MUST check your laptop's input voltage and your original ac adapter's output voltage. For example, laptops with 18V-20V input voltage can use our ac adapter which has 19V output voltage; Remember: never exceed ±1V tolerance. 2. You can calculate your original ac adapter's output Wattage [W] by multiplying the Ouput Voltage [V] by output current [Amps] i.e 19V X 4.74A = 90 Watts. You can choose a replacement ac adapter which has higher Amps than your original ac adapter's; but you can not choose an ac adapter which has lower Amps than your original ac adapter's because it can not provide sufficient power to your laptop. 3. Please carefully check the plug tip's size of the adapter to make sure it can fit into your computer.
