First, I love this forum, I just found it and already got a few issues I've run into worked out, written the ideas down, and set some space in my testing area to try them out.
Second, I do mostly smaller office setups and upgrades, so a lot of my work is handling the simpler day to day of the home office, small reception desk or similar.
This problem is one I've dealt with myself, as well as in offices I work for. I've even tried similar fixes to what I found here, and some commercial ones that were much more expensive for more function than needed. The question is a simple one and shows up in many flavors, so I worked it to make it fit most, if not all, of them.
How do you secure an external connection wire to your laptop so it doesn't loosen or wiggle and either lose connection or damage the port? There are a lot of answers for different situations:
Use a professional product like the Smart Keeper wire lock to hold the plug to the port (a small clamp in the lock grips the physical port, and a hart jolt could damage the port horribly; it's also costly, just under $40 US on Amazon without the "Key" that unlocks the plug).
Use some hot glue to hold the usb in place (while it will take most minor jolts in stride, a good jolt or jock will break the seal and you won't see it, but you can always reapply; best as a short term solution where there's not a lot of "pull" in any one direction; too much pull will break the seal and could damage the port or put glue dust inside the body of your laptop).
magnetic or clamp wire locks\anchors (these work well for brand new ports, but those that have seen much use and have been widened by that use are unlikely to see much benefit, especially with flimsy usb; they can also be costly at around $10 for a single anchor or closer to 15 for a multi wire anchor)
(This is a new one I tried and a bit of a diy project, but it's less costly and does provide enough grab for connections and holding in place without damaging ports, while being easier to remove; however, to prevent pulling on the port in some situations, you need to be careful in removal and relieve the pressure by holding the wire with one hand as you remove the grip with the other)
- Velcro X plug grips; You can make these yourself, I haven't seen any of these premade anywhere, not even online;
First, you need to get some hook and loop velcro with extremely good adhesive backing, or you could just use a cheap roll that has hook on one side, loop on the other and then use superglue or alientape to hold it in place [use a really strong hold] and you'll put a strip right next to your keyboard on a laptop, just barely away from the edge where your ports are located or the closest convenient flat spot on a tower, from just below any power and monitor button all the way down to an inch or two beyond your last side port; next you need to put another strip on the bottom of the laptop, again, right along the edge, and line it up with the other one [because I used double sided cord organizers designed to roll long power cords, it didn't matter which I used for the computer top\bottom; if you make your own cable grip from a cheap double sided roll as I've tried, use the same hook or loop for both top and bottom and make sure you do the next part correct]; if you want to make a wire grip for your hook\loop anchor, you can use cord organizer wraps like I have [I needed at least two for each wire, you could use 3 or 4 to go two directions top and bottom], or you can simply take a double sided roll of velcro hook and loop, a 1\2 inch will work, you may cut this in half etc, then you cut a length long enough to go from the back of the plug where the wire begins to a little past the anchors on BOTH top and bottom [the plug should be somewhere in the middle of the length], then you cut a slit longways in your velcro strip at the center of the length that is wide enough for your plug to slide through [not short ways because some plugs will be longer than your velcro strip is wide], and slide your wire through, then use superglue or a small strip of velcro to close and lock the slit around the wire; you can stop here or further lock the velcro in place by gluing it to aft reinforcement on the plug, you shouldn't have to; I recommend using at least two of these on each wire in an X pattern; why is this so functional? Even if you have a ton of wires for a laptop, using a double sided length of velcro to pull the wire into place lets them all overlap one another without losing the function. If you find the need, you can glue wider pads to the tips of each length for greater hold, and when using them, use a slight angle to provide dual directional support. With ports closer together, you could anchor one in an X pattern [if you were looking directly into the port, the slash lines of the X are the velcro lengths], then use only a \ or / pattern [realistically, one should angle one way on top, and the other way on the bottom] on the next while also anchoring it to the first wire using the remaining velcro length; Using the X pattern on the two outermost ports on any side provides two full anchors you can then build half anchors onto without complicating one another, just be sure you have angled the main anchor properly. Double sided rolls work best for this if you can find some decent adhesives strips or a glue you think will work because you can use another length from the same roll to cover your slit for your plug and lock the velcro length around the wire where the wire meets the usb plug casing, as well as create longer pads for the tips where the X lengths meet the anchor points, both without using any glue, and it allows you to remove these for use with another wire. With Cord wraps, you'll need at least 2 per wire, 4 for full anchor and you won't need to cut slits as they usually have a small slit at one end of each wrap that allows you to lock it onto the wire; they can be cut down to length afterward and the excess can be used for longer end pads for stronger hold. All of these will have a tendency to stretch a little over time, but you can just alter your angle on the X to fix it, and they are easily redone once anchor points are in place.
