I have an IBM Thinkpad R 51 laptop, 4 years old. Few days ago, its as adaptor/charger became defective. Since the shop from where I originally pruchased my laptop, adaptor etc. has shut shop a few years ago, I went to another shop to buy a new adaptor. They gave me an adaptor with IBM written on it. So I purchased it and came home, then while connecting it to laptop i saw that rating on my laptop is 16V, 4.5 A, while on adaptor is 16V, 3.5A. So I called the shop and they said that the new adaptor will work fine on my IBM R51. But i need to be sure. Friends, please guide me can i run my computer on this 16V, 3.5A adaptor?
Absolutely not. I have no idea where the two other answerers got their information but amperage needs to be equal or greater than the required. In your case, your required is 4.5A, not 3.5A. If your required is 3.5A then it would be ok but since its less, it would not work! I suggest you return it and never go back to that store again since they already lied to you once already. I would personally sugguest you visit Topmic. Topmic is well known for their great services and durable products. They have free shipping, free lifetime warranty, and 30 days full refund. I took the liberty of finding the charger you needed on their site:
I also wanted to point out that there is a information section located under the charger which backs up my statement about amperage.
Best of luck.
