surface connect port pinout

with zero-insertion-force and magnetic positioning so its easy to hook up. So I think it's much more likely a problem with my hack-y replacement contacts (long narrow strips of thin copper foil laid over the plastic connector and the holes where the contacts used to be, then wrapped around the back side of the remnants of the original connector, and soldered to wires that run to a laboratory DC power supply) rather than a problem with the suggested pinout. That only provides power.

The laptop was drawing current this morning, but not charging (and the voltage reading was lower than I'd expect (maybe? the center pin is used to energize the four power contacts with full current capability. You can not charge with the USB port. There won't be any people in or out until then either, so he can't even ask someone to hand-carry one here. The connector in question is missing 7 out of 8 of the power contacts (they got etched away... long story). :). Inconclusive.

Press question mark to learn the rest of the keyboard shortcuts, SL1 i5/8GB/256GB / SP3 i3/4GB/500GB (upgraded storage). That's not to say I doubt /u/id000001's advice. Does anyone know the pinout for the charger (the end part that mates with the computer)?

The same wait until all four power connectors are seated before applying the full current from the power supply to the computer; occurs when connecting the power supply connector to the computer. New comments cannot be posted and votes cannot be cast. Cutting the connector off and removing the wires insulation, there are four wires inside: Thick red wire is +12v.Thin yellow wire connects to +12v to delver full power. The higher the water sprays, the higher the measured voltage. You simply can't do this with Thunderbolt. will I only need to fix one ground/12V pair, or do I need to fix all 4)? And based on some posts I've seen elsewhere, I think the outermost (closest to the edge) contacts are +12V DC, the inner most ones are ground, and the middle one is .... something else... possibly a charge sensing thing.

Do you know if it requires the detector circuit to charge? I'm trying to repair the charger cable for a friend's surface pro 3.

If you know the answers to any of those questions, I'd very much appreciate any input. (Even if verrrrrry sloooooowly?).

Frank's record of a bit of his life. This post and comments has helped. The Surface Connect port is the only one on the market that combines high bandwidth data, power delivery, video, etc. The good news is I have not yet fried the computer or set anything on fire. Saved me some trial and error, thanks! The pin out are duplicated on each sides. You will notice the center pin requires full contact of the four power pins before the center pin makes contact. A subreddit for the Microsoft Surface family of products. I think each of the 4 groups of three contacts are probably all repeats of each other (they have to be at least repeated twice, since the charger is reversible).

Basically, we have to fix it, or he'll have no computer for 4+ months.

I believe the centre pin is for overcharge protection. ).

SP4 is DC 12V @2.58A, but it will charge down to 1.2A (I tested this with a different adapter with a millimeter. Anything but ordinary.

I'm trying to repair the charger cable for a friend's surface pro 3. Or does anyone have a working charger and a multimeter and a few minutes to check the pinout by hand? Comments have to be moderated because lots of spam comments. There won't be any people in or out until then either, so he can't even ask someone to hand-carry one here.

Also does anyone know if the mystery middle contact is required for the surface to charge? I cannot find anything about the PCIe part of the dock connector online.

Once the connector pins are seated and the center sense pin makes contact, then the power supply can ramp up the current necessary to charge the battery and operate the computer.Voltage is like the height a water hose can spray and current is like the diameter of a water hose.

He can't just buy a new one because we are in an extremely remote location and there is no mail service until November. Has anyone tried charging the Surface via the USB port? xda-developers General discussion Questions and Answers [Q] MS Surface Cover Connector Pinout by Greg00135 XDA Developers was founded by developers, for developers.

He can't just buy a new one because we are in an extremely remote location and there is no mail service until November.

If you have one, and a few minutes to spare, maybe you could check with yours by carefully putting tape over some of the contacts and see if it works or not? Can someone confirm?

Hello , could you please make small drawing for the wires coolours and 5 pin connector . Also, do you know how many of the 4 sets of contacts have to be connected for it to charge (i.e. Does it charge at all?

While a diode connects between GND and the yellow wire.When the yellow wire is connected the blue wire turns to +5v.I can't work out how the surface connects the yellow wire to +12v.Even though I haven't figured out fully how t works hopefully someone will found this useful.

Counting from the outside in this order: G 12V DET. Assuming the groups of three contacts are just repeated 4 times, how many working ones are required for the surface to charge?

I don't recommend charging the surface via the USB port. However I do have a pinout of the larger surface connect port in the middle which carries USB, display port and power between the tablet and base. I have a new post with more information here: http://thomsoneu.blogspot.com/2020/05/rebirthing-surface-pro-2.html, Strength Fitness Warmup Stretching Rowing, Dans 13th Birthday Party at Kingston Park, Dan BGS middle school celebration of the arts. Got that concept? Or is that only required if I care about the LED indicator light working? The idea is, when disconnection occurs, the center pin will not receive a + voltage from the computer and the power supply will instantly drop the power level available … The larger the water hose diameter, the more current available.Voltage can be measured with a volt meter and current with a current meter. Thin blue wire connected to the centre pin shuts off the power when connected to +12v.Opening the connecter revels what the yellow wire connects to.The yellow wire connects through a resistor to an led and then to GND.

This slight pin height gives the power supply an advantage to reduce current supplied to the four power pins when the connector is disconnected. The idea is, when disconnection occurs, the center pin will not receive a + voltage from the computer and the power supply will instantly drop the power level available to the socket in order to reduce the spark at the connector. By-the-way electrons flow from the power supply via the negative terminals, loop around inside the computer and computer battery, then return to the power supply via the positive terminals. I'm really hoping I only have to deliver +12 V and ground to two or four of the contacts... the little circuit board that's inside the connector is pretty heavily damaged; I doubt it's repairable, though I could conceivably make a breadboard version. using adaptor can work normally once take out the Window Surface Pro 4 will shut down this is a cause, I bought one of these power supplies from an op shop, wondered why the voltage collapsed when a load was applied. I dunno), even for a near-dead battery). This information definitely came in handy when repairing a relative's Surface charger where only the red wire was still connected. A Taste of Moogerah - Parent & Son Weekend.

And no. The power supply can provide +12.3 VDC at low current and this will not cause a damaging spark at the connector pins. Surface Pro 3 Dock Connector Pinout About Photos Mtgimage. the center pin is used to energize the four power contacts with full current capability.

My current info (based purely on speculation) is: 2 PCIe lanes per "side" Likely SMbus (clk/data) and REFCLK on both sides I brought back some thicker copper foil from my lab today, so I'll try that and hope for the best.
