"Expansion port 3" pinout, function of pins and signals

Q: "Expansion port 3" pinout, function of pins and signals

Hi folks! Is there a place where I can find technical information regarding the "Expansion port 3" ? I was thinking on building a docking station that could suit my needs, as I could not locate a docking station that could be used with my laptop. If you know the pinout, function of pins and signals of the "Expansion port 3", please, drop me a note, OK? Thanks in advance and regards, Mike

I have a P1 GEN2 OLED. While the internet is flooded with complaints of the OLED screen itself, the thunderbolt 3 port of my P1 GEN2 magically stopped working for no reason.  I have been using the laptop with an external display ever since I got the laptop. All went well. Suddenly from yesterday, the external display starts turning into a blue sreen with "NO SIGNAL" shown on it.  I had a windows cumulcative update (KB4532693) and windows security update (KB4524244) yesterday and I suspected that the update might be the culprit. I rolled back the OS. No change. Still NO SIGNAL.  I searched this Forum. Played with Thunderbold 3 menu in the Bios. Everything was enabled and every single option of "security level" was tried. Still NO SIGNAL.  I checked Intel Mangaement Engine software. It is already the latest version. Reinstalled it. Still NO SIGNAL.  I checked Nvidia driver. Latest version already.  In sum, the problem is: the thunderbolt port is still able to power the extenal display but just simply does not pass signal to the external display. HDMI port, however, still passes signal if use an HDMI cable.  I want to give it a shot here to see if anyone has experienced similar issues and how they sovled the problem before I call Lenovo technical support, the staff of which does not seem to know more than some people here on this Forum.

I am considering on purchasing a Gigabyte Z370 HD3P motherboard to start a new computer build. However, it lacks a PCIe x8. After a bit more research, I found a Gigabyte Z370 UD3H that had a PCIe x8. And, it would cost $100 more. However, It is only sold outside of the US. and Gigabyte would not say why. The Z370 UD3H also has Dual m.2 ports, a PCIe x16, PCIe x8, PCIe x4, and 3 x PCIe x1's However this board is only sold on Alibaba in China. I'm afraid of the expense of the cost of customer support if I have touble with the motherboard. I'm also trying to consider upgrades in the future. I use my computer primarily for eBay sales, accounting, photo collections and am considering on looking into gaming.

If I decide to go with the Gigabyte Z370 HD3P, am I giving up much to be without 1-PCIe x8?

I have a 320GB Seagate Expansion Drive which worked fine for several months, but in the last week or so the only way I could get it to register on my computer was to push the USB plug into the port on the unit very firmly. This sometimes caused the drive to work for a while, but then later ceased to work when I let go. So, I decided to tape it place very tightly. Wrong move! The whole USB port came loose from the mother board! Is it possible to have this fixed? I have a lot of stuff on the drive I don't want to lose!!!

A:USB port loose from Seagate Expansion Drive

I'm not entirely clear on what you are describing. Are you calling an external hard drive and "expansion drive" or is the "expansion drive" a drive physically mounted in a chassis? An external hard drive doesn't have a motherboard.

If the USB port came loose on an external drive enclosure adapter you could remove the drive from the present enclosure and install it in a new enclosure if the external drive is an IDE drive or a standard SATA drive.

Posting a picture may help decipher exactly what you are describing.

Hey guys,has anyone tried a 54mm 3 port USB 3.0 Express Card in their X220?I found this one on eBay... AKE Laptop Notebook 54mm Express USB3.0 3 port 5GB/s HUB T Card adapter FL1100http://www.ebay.com/itm/AKE-Laptop-Notebook-54mm-Express-USB3-0-3-port-5GB-s-HUB-T-Card-adapter-FL11... I've noticed a lot of 54mm 2 port USB 3.0 cards on ebay and in other notebook forums X220 users have said they are using 2 port cards with no issues and no need for power cable so I'm wondering if 3 port USB 3.0 would work? Cheers


Go to Solution.

A:X220 Expansion slot fit 54mm 3 port USB 3.0 Express Card?

I would imagine that as long as you used a USB 3.0 device which did not require external power (like a USB flash drive) or had an external power adapater (like a hard disk drive enclosure) that things would be fine.  You might want to contact the seller and ask what the maximum current is for each USB 3.0 port, and whether or not the card can supply that simultaneously for all three ports.

Summary: Line out port on my pc is completely ****ed. I have to spend 5-10 minutes messing around, jerking and twisting my audio cable before I can get sound. Tested with 3 different devices. I've heard you are able to configure the line in port to function as a line out but google hasn't proved to helpful. Any idea on how one might do this. Using intergrated hd audio on my motherboard Asus m2nbp-vm csm.

A:Configuring a line in port to function as a line out port.

Usually,it can only be configured as something like 5.1 which
would enable the rear outputs but wouldn't give any front audio

Might think about getting one of these and disable the onboard.
These are supposed to work with windows 7 too.

I recently replaced my mainboard and processor.

I installed my DFI Lanparty UT nf3 250gb and my new sempron 3100+ and everything went very smoothly. I have a brand new 120gb Samsung drive with a fresh install of Windows Xp. Here is my problem.

The Line Out port on the back of the mainboard (onboard sound) does not function. I have resorted to plugging my speakers into the Rear R/L port and using it this way although I don't see this as ideal.

Any help would be appreciated.

does your board support fp audio ports? if so, then refer to your manual and find out where this jumper blobk is located. to complete the circuits to the back panel ports, there needs to be one or more jumpers installed on said block as your manual indicates. check that first, as it is most likely the cause. but you have gone over your windows and bios settings twice, right?

I just put a system together with a Compaq Presario 5000T motherboard (motherboard model 686C3 with P-III 933) and am having trouble getting the front case USB ports to work. The header on the board looks like a standard 9 pin header but no matter how I connect to port cables I get a "unrecognized USB device" message in Win XP. I've measured voltages on the pins and get 5 volts on the first and third pins instead of the standard first and fourth. I've rewired the connector on the cable to the front panel accordingly but no luck. Seems like no matter how I arrange the wires into the header I get the same message when I plug my thumb drive in. The thumb drive reads fine when plugged into the rear USB connectors on the board.

I know it's usually a waste of time trying to make use of old Compaq parts, but other than this problem the board actually hooked up and runs great in a new mini ATX case. If I can get this little annoyance figured out I'll have a pretty decent little machine for cheap.

Any help would be great. Thanks

I am installing an Intel motherboard into a case that is equiped with 2 front panel USB connectors. The case came with no documentation.

c)VCC (red)
d)Ground (black)


I found the following on the intel site:

Hello, I moved my z420 workstation mainbaord to a different case (Fractal Design R4) and keep running into the screen that notifies me of different panels not being connected. So far I was able to solve the issues with: Front Panel Audio, USB2.0 and ieee1394 due to searchin through the HP Forums and figuring out which pins need to be connected to ground in order for the mainboard to pass the test.One issue I can`t seem to figure out / get to disappear is "939-Front Panel Usb 3.0 not connected".I have connected the USB3.0 cable from the case and it still displays this issue - reading through the forums I came accross that z420/z620 have a USB3.0 redriver .Do I need the original panel to make the board believe that usb3.0 is connected? Is there any other way of fooling the mainboard that usb3.0 is connected (similar to the detect pins with audio and usb2.0?) Since the pc will be running 24/7 as small fileserver, I don`t really need front usb3.0 - I`d rather have it boot normally after a power failure and not needing to be physical present to press f1 for it to bootAny help on how to solve this is highly appreciated

Does someone know where I can get the pinout for the 10 pin header called "PB/LED" labeled P5 (connector) on the MS-7860 Ver 1.2. (Pro 400 G1 MT)? I have seen manuals that avoid that connector. Note the "missing or key" pin is exactly in the middle (pin #6). I have seen many diagrams with the key or missing pin at one end. That is not my board. This is where the cable containing the power switch (not to be confused with power supply) meets the Motherboard. I am replacing a failed Motherboard (three Months out of new Warranty with no physical indications of damage) with an ASRock H97M Pro4. I has every other connector perfectly wired. The only one I will have to "convert" is P5 (on the very outside edge of the SATA port corner). Thank you for your help.

I am trying to connect a FIC K8MC51G motherboard to a case. The case has a front panel for two USB ports. Each port has a connector for VCC, D+, D-, and ground. I don't know how the pinouts are set up on my motherboard. It shows an arrow and a two next to two of the pins. I'm assuming the arrow is pin 1 and the 2 means pin 2 so if I follow that logic, I at least know which pin is which.

The problem is that I don't know which pins should be placed where. I can't find the manual.

And the front audio is even more confusing. I can't tell which pin is what number since the one with the arrow also has a number 2 next to it. Any help would be appreciated.

Hi guys,

I am replacing the stock fan/heatsink on my HIS Radeon HD 6790 with the Arctic Accellero R2 Plus. This fan has a 3 pin and 4 pin option for the fan. The stock fan is only 2 pin...black and red. The aftermarket fan's wiring is black, red and yellow, and black (ground), red (VDC), yellow (signal) and blue (PWM).

My question is can I just splice the original connector with just red and black into the aftermarket wiring? The fan came with a molex adapter but I'd rather the video card be able to regulate the fan rather than it just be going full out all the time. Is the factory red and black also considered VDC and ground?

Thanks in advance!

I have also found an adapter made just for this purpose from moddiy, however without any pinout information I do not just want to blindly trust them either.Thanks in advance for any and all help.

Hello all. I have HP Pavilion 15-n031sr notebook, model F2U14EA, OS Ubuntu 14.04. With my notebook i want to use  headphones and microphone with standard three-contact stereo jack plugs.  User manual for this notebook says: "NOTE: Be sure that the device cable has a 4-conductorconnector that supports both audio-out (headphone) andaudio-in (microphone)." So, i bought converter where 4-contact male pluged in notebook and  two female sockets from the other side: green is for headphones, red for microphone. I don't know what pinout of this converter is, but headphones plugged in green sockets sounds fine; it's stereo and clean sound. But when i plug my standard 3-contact mic into red socket it clicks and produce huge noise in my headphones.  My questions are: 1. What pinout of headphone/mic socket for this notebook model? CTIA, OMTP or some else?2. Is it really unsafe to connect 3-conductor phones directly into notebook socket, or i may use my standard headphones without any converters?3. Is large clicks on system startup and shutdown (with no mic) causes by incorrect converter? 

A:HP 4-conductor headphones/mic jack. What kind of pinout: CTI...

This is a puzzel, have a similiar problem.  You use the Mic and Ground for the Mic and the Left/ Right Ground for the speaker on the to jacks on the left side.  If you use a splitter you (we) still may need a four connection mic Jack. I tried two different splitters that killed the audio, however I used a conector similiar to the first and second one from the right for the microphone and the speakers, causes a mismatch on the microphone Kills the speakers. presume that the splitter uses a 4 contact on all connectors. So I presume that the microphone only will needs to have a four contact jack. Hope this helps. I either have to buy a four contact jack and rewire my microphone or find a three contact to 4 contact microphone adapter. Found the connector on Amazon    3.5mm 4 pole connectorhttps://www.amazon.com/Areyourshop-Plated-Stereo-Repair-Headphone/dp/B01CJE03OW/ref=sr_1_13?ie=UTF8&... Hope this helps
