Calling electronic Oppo's

I was given a free laptop. It’s about 5 years old, but i7 and 8gb means it’s SIGNIFICANTLY faster than the laptop I’m currently working from (A6, 4gb, from 2011). The problem is that it’s got a broken power port.

So, I know I need to strip it down and take the mobo out (incredibly easy on the Samsung, it’s put together like a phone) and have the old port de-soldered. My question is, do I need to put the exact same port back on, or can I change to something more common?

What do you mean by changing it to something more common? Your charger will only output a certain voltage/amperage required by the computer to run and charge. If you get a different port, that charger will no longer work with that laptop unless you have a charger that fits the NEW port type, but outputs at least the SAME voltage (no more, no less) or the same amperage (or higher).

Also, it depends on the pinout...which portion of the port’s connector/charger’s connector carries what (ground, power).

Just stick with the original port type and charger. Desoldering it shouldn’t be too hard if you know what you’re doing.

As long as you have only 2 leeds on the motherboard, a positive and a negative, it will work. Some power supplies will provide additional voltage with additional leeds in the power cable, you want to watch out for that.

Have you considered looking on Ebay for a replacement mobo?

If I were going to replace the DC jack, I’d replace with the same. A replacement charger can probably be had on Ebay for $10.

You want to replace it with the same. It’s designed for a specific input voltage, and switching size likely means you are getting a different voltage (their are exceptions, but easiest just to keep everything the same.)

Depending on how bad the existing port is, you may just be able to solder the broken connection, either directly, or with a wire. Could be easier than desoldering everything and putting in a new port.

As long as voltage, amperage and polarity of the new input/power supply match your computer won’t care ( so long as it’s only hot and ground wires and no additional data wires)
