If your laptop model is not listed here, kindly match with the output rating from your old ac adaptor, as given above. If it is same, you may buy this adaptor.
Important Note :
1.Before ordering this ac adapter, you MUST check your laptop's input voltage and your original ac adapter's output voltage. Laptops with 18V~20V input voltage can use ac adapter which has 19V output voltage; Laptops with 15V~17V input voltage can use ac adapter which has 16V output voltage; Remember : never exceed ±1V tolerance. Using wrong output voltage adatper will damage your laptop computer.
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 X3.42A = 65 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. Adapters with higher Amps will not damage your laptop computer. The adapter's output current (Amps) and output power (watts) are maximum load ratings. Computers only draw as many amperes or watts as they need.
3.Different laptops have different connectors. You need the right tip for your laptop. This is very simply to find. Basically, laptop AC adapters comprise of 2 ends. One end is male power outlet. You use this end to plug into wall power outlet. The other end is called "TIP" which you will plug this tip into the "DC IN" in your laptop. Your laptop won't work on the wrong tip.
I purchased lenovo G460 laptop battery with Shreelaptop online this product is very good i get above 3 hour battery backup ...Very nice product..
the package was well protected and in good condition when i received it. I totally recommend it.
I like your doorstep service apart from your product It was unbelievable for me to receive my order at my home since my address is at remote location where courier is unable to reach with reason out of service area.
Have bought 3rd battery from Shree Laptop Solutions. All of them worked well. Last two lasted for more than one and a half year, which seems a good life for a replacement battery.Wish I could get discount on next purchase :)
