Hi,
I wanted a second AC adapter for my laptop and i couldn't find an universal adapter with the right output plug. The guy from electronics shop sold me the right fitting plug and told me to solder it to a compatible adapter. He told me it should be easy, to just solder the inner wire to the center of the jack (negative pole) an the outside wire to the outside part of the jack.
I bought an universal AC adapter with the same specs as the OEM one (19v 2.1A) and cut the DC chord. The problem is it has 3 wires, one red (the hot one), one black (positive) and a white which i think is ground. I soldered de black and red to the plug and ignored the white one.
At first it seamed to be working fine, the computer detected the power adaper and gave the signal that it was charging. But soon i realized it was not charging the battery nor feeding the computer.
What did i miss? should a power adapter have 3 wires connecting to the DC output plug? what's the third one for? why don't the computer charge? It might be something Can anyone help me?
The power adapter brand is "eurotech", if it helps.
Here's the laptop specs: http://media.wix.com/ugd/238d97_645306ef26ed74d3632353c4ed2b4879.pdf
