Inspiron E1705/9400 charge adapter compatibility

Hi all,

I bought an Inspiron E1705 notebook last year from U.S and now I am at abroad. Unfortunately, my charge adapter has brake down. I ordered a new one from local supplier but the problem is that: My original charge adapter has output for 90Watt, 19,5Volt and 3,34Amper. On the other hand the new one which I bought from local supplier has output for 90Watt, 19,5Volt but 4,62Amper

I am really afraid to use this because some of my friend mentioned about the possibility of motherboard burning. Only for one time I had to use because I had to switch on my notebook and the battery has been charged very fast but it warmed easily. Should I use this new one or give it to back? Moreover, I am curious about what is the drawbacks of charging battery with an over-current?

Thanks for your interests...

 

I have a similar issue in my post here:

Hi, I am working on a E1705 with a charging problem. I can tell you how to figure out the wattage of the power supply. You mention the original that came with the laptop as being 19.5 volts and 3.34 amps. I have the same power supply. If you multiply the volts by the amps you arrive at the wattage. Thus 19.5 X 3.34 = 65.13, or 65 watts. This is the power of the supply, which it can provide to your laptop. All the replacements I have found on-line are a higher rating, just as you say. Thus 19.5 X 4.62 = 90.09, or 90 watts of power. As you can see you said at first that your original power supply had 90 watts. This would be impossible by the numbers you provided for the first power supply, but correct for the new one. My original power supply shows 65 watts on the unit. There should be no problem with the output being greater by 25 watts. The voltage is the most important for the laptop, the amps are simply more available power delivered in amp hours.
The more amp hours the more you can run the laptop, and charge the battery at the same time. Since all the sources I have gone to upgrade to the higher rated power supply it seems to be the choice to make, and should not cause any overheating of the motherboard. I can also tell you that the 65 watt power supply does not show up on searches for the E1705 by model number that I can find. Perhaps someone has bought the wrong one for yours, and the one I am working on. Hope this helps.
