what is a port replicator?
322871
It is a thing that replicates the ports of your laptop, by forwarding data to and from its own ports. Docking stations like this one usually are also port replicators. E.g. your laptop has ports: USB, audio, network, VGA/DVI/DP (external video for a monitor) and more. The docking station has the same or bigger set of ports, and when you drop your laptop on it, they are automatically mounted as if they were internal laptop ports. You can attach a bunch of cables from stand-alone keyboard, mouse, several monitors, speakers - all to the docking station, and when you drop a laptop on it, they will be all instantly re-attached. That's why it's called port replicator. It's often that port replicators have more ports than the laptop had originally. E.g. laptop may only have a VGA port for one external monitor, but a docking station may have two (VGA + DVI or VGA + DisplayPort), so you can make a better workspace. It often has more USB ports as well. I am seeing 4 on my ultrabase, but the X220 itself only has 3. I think buying an X-series laptop without a decent docking station/port replicator means getting substantially less value for your money. Since I tried it for the first time, buying a docking station is a no-brainer decision for me (and it's also the reason why I don't buy certain brands of laptops - some of them do not come with good docking stations).

It is a cheap answer for a docking station. Instead of plugging your computer in to a docking station, the port replicator has dedicated input ports. They are then combined into one by the replicator with a single USB to connect to your computer plus power. So instead of plugging and unplugging 4 or 5 or more cords depending on how many peripherals you have it's just 2, at least in theory. I could never get the printer to work. Other things like the key board and mouse had to be reset from time to time. I ditched the thing and bought a docking station. I have been much happier with the docking station. Pop it in and pop it out. It's worth the extra money. It is a cheap answer for a docking station.

It has a port forwarding configuration, but I haven't been able to get it to work. I haven't tried all that hard, though.

As best i remember....yes. Since the amperage is usually higher than the one for the machine (peripherals attached via the station), the plug has to match the replicator.

This unit is only designed to copy 2 duplicate USBs from one master USB. I do not believe it is designed recognize a USB hub to take place of one of the slots to duplicate a USB. I'm attempting it now with 2 gb worth of data ... it has taken 33 minutes and is only 45% finished. It is really bogging down.

None, the systems ships with only the power adapter. I recommend getting a USB 3 Port replicator with/without power.

My port doesn't work any more . It like all cell connection ports is made cheaply. It lasted about a year. I now bought an extra battery with a battery charger from radio shack and charge my batteries this way.

I'm not sure why it's so difficult for the HP representative to give you a yes/no answer. If you go to hp.com they do appear to sell port replicators for the HP Envy line.

What is a dock extender? What does it look like? What does it do? Where do you buy one?

Dell Latitude E5430 E5530 E6230 E6330 E6430 E-Port Replicator Dock Station PR03X.....it will work with it!!!

Yes, and this is the reason I bought one. It's cheaper than having the port repaired, which can run $80 or more.

It is realiable and I have never had a loose port issue. I own three of the LaCie Rugged Harddrives...one standard and two portable. Never have had a problem, always runs fast.

Yes it does, 2 of the ports on the relay pack stopped working on the 2nd gig I had. Buy with caution!

Hummmm. Darnn thing stopped working months ago. More like a no port. Not sure what your question is but this thing turned out to be a waste of my money.

OK, I see the confusion. I have a Lenovo W500 for which I need the Lenovo ThinkPad Advanced Mini-Dock Port Replicator (250410U). I originally ordered the Lenovo Mini Dock Plus with USB 3.0 - 90W but this did not interface to my W500 and so I had to return it. So my answer was in reference to the 250410U and unfortunately does not apply to your situation. Sorry.

Not sure what you are asking. Some new computers have A drive facility but a separate drive dock is necessary. This device permits you to operate a floppy via a USB connection.

All 2.5" or 3.5" SATA Interface HDD or SSD can be fitted into this Aleratic Duplicating Dock. Target Disk must be of same or larger capacity than the source Disk.
