Dell Inspiron 3721 :: SuperSpeed USB 3.0 Docking Stations - Network Cable Unplugged
Jan 3, 2014
Our company recently purchased two Dell Inspiron 3721 Laptops (Windows 7) with two SuperSpeed USB 3.0 Docking Stations. Both laptops are fine and can connect to the network, but both network adapter on the docking stations don't seem to work on either computer. The lights on the network adapters for both docking stations don't light up and the adapter settings on the laptops show the LAN connections as "Network cable unplugged." The cables work, as we tested them on the laptops themselves. We've also tried uninstalling and re-installing the drivers with no success.

I tend to take my laptop around a lot and I get kind of annoyed at having to constantly hook up all the various USB cables and the monitor it interfaces with.
Docking stations seem ideal for convenience, but they seem awfully expensive.
Are there any affordable docks or USB hubs out there? Like less than 30-40 dollars?

I have tried looking at Dell's webpage, but couldn't find any lists over compatible docking stations. Not to mention that when trying to "buy" another identical computer dockings are never mentioned in the "Buy accessories for your Dell" subpage. I have seen a few cheap, used docking stations on the web, but I don't know if they will work. This is the one I can get really cheap:
Would that work on my Preceision M6500? It's for my second and third office (a.k.a. my wife's pet shop and our cabin by the sea), so I need two dockings. And this way I can save 80 % of the cost!
For some stupid reason the M6500 has no SPDIF output, and I see that there is one on this docking. But I don't care if that works or not, I only use SPDIF at home, and I have an USB sound card with SPDIF there.

My wife and I each have new ZBook 17s that work fine on our wireless network. How do I force them to use our wired network via CAT5 cable connection? There is a button that turns off the wireless, but that doesn't seem to do anything except turn the wireless off.

My Inspiron 17 3721 won't turn on and beeps and pauses for a second and beeps again. It is just a black screen and to make it stop beeping I have to hold my power button down for 5 seconds. It is a windows 8.

Recently bought Inspiron 3721... When I try to download some of the driver links are not working. For example Dell Application.
I have already installed all of the drivers on my Windows 7 x64,but I'm searching for a program to control my fan. Or a Bios update?
Is there anything for fan control on my laptop because almost all the time it is at max and is getting annoying.

My laptop INSPIRON 17 (3721) has problems to start and makes 5 beeps. I saw in other forum that it is a matter of the coin battery. I have already changed it and it is still doing the same. It doesn't show video, there's no fan noise but the power led is on. After about 5 minutes the fan starts.

I had to have my motherboard replaced because of some audio issues and after I got my laptop back i noticed something that hadn't been happening before.
As soon as I turn on my laptop the fan start working extremely loud with cold air coming out. I know that the fan is supposed to be this loud when laptop is close to overheating, but I don't see the point of being this loud while everything is on normal temperature (checked with SpeedFan) and laptop doesn't feel hot at all.

I just bought an Inspiron 17 3721 running windows 8. The cooling fan runs continuously at one speed. I have had numerous laptops and none have done this before. Is this normal?

I'm setting up a my new Dell Windows 8 laptop.Now, I'm trying to create a set of recovery disks in case anything goes wrong, I'm using Dells own software. Unfortunately there seems to be an issue with, in other words its pish, and it fails after creating the first disk when it needs to create four. Every time I put a second DVD in it just ejects with no error message.it seems that a lot of people around here are having the exact same issue. It wouldn't be such a problem if you could boot into the recovery partition by hitting f8 during boot, the only way you can access it,though, is by holding down shift in windows 8 and pressing restart which is absolutely no use if windows won't boot!! I've got a hold of Acronis True Image 2013.
My question is can I make recovery media by creating a boot disk and then creating and image of the PBR partition, which I'm sure holds the recovery data? I can't back up the whole system as there is now 120Gb in data on it. I don't wan to back up the whole system, I just want to be able to restore it to factory default,in case anything ever goes on it, by using DVD media.

This morning, my Inspiron 3721 (18 months old) failed to turn on. Worked fine last night.
Symptoms: on pressing power button, only power light illuminates, but no other noises, no fans, no screen response.
Have removed battery, removed power lead, held down power button for 50 seconds. Reconnected battery & power lead, but no change to above behaviour.
Tried a different power lead but no change to above.

Whenever I unplug my laptop from external power, the screen considerably dims and the taskbar turns white over it's usual blueish black. I've gone into the power settings and changed them so that brightness is 100% when unplugged, but to no avail. According to my computer it's at maximum brightness when unplugged but it's obviously not. Trying to increase the brightness by the sun key or pressing Fn up doesn't work either. Tried to go into BIOS via F2 but couldn't find a video or brightness option.

my Inspiron 17R no longer recognizes when it is unplugged from the AC adapter. This means that when you check the power icon it always claims to be connected, even if it's not, and that the charge meter basically can't be trusted (it'll say it's fully charged when it's not). It also means that it fails to adhere to its power plans because it never goes into battery-only mode. I have contacted my local Dell tech support, but after checking my bios and seeing that my computer recognizes the AC adapter, they didn't know what to do. how to get my laptop to properly recognize when it is and isn't plugged into the power supply?

I have an XPS M1530 running Vista Home Premium 64-bit, T-9300 Processor, 6 gig RAM, 320 gig 7200-rpm harddrive. I am using it with the Kensington SD100S Laptop Docking Station (with stand) and a 22" Samsung monitor (monitor as primary display and laptop display as secondary display) and the Dell Bluetooth keyboard and mouse. The Kensignton docking station attaches to the M1530 via USB.
My question is, is it safe for me to detach the docking station when the M1530 is booted up and running? What about detaching the monitor? Except when I have an external USB harddrive turned on, there is not anything in my tray icons to indicate (as far as I can tell) that any hardware needs to be safely removed.
I have a 2nd AC adapter in my den separate from my home office, but I so rarely take the laptop mobile in the house since I power down first. Please let me know whether I am being too cautious, and if it is safe to detach the docking station and monitor while running any precautions that I should take. I do have my XPS backed up via Ghost if a problem should happen.

I have Inspiron E1705 with WUXGA (1920x1200) which I want to connect to my rear-projection TV that has only component video inputs.
I've bought this S-Video to Component adapter:
[url]
But when I switch to external monitor (TV) via Fn-F8, the screen switches to 1024x768 (TV starts showing in that resolution too), and there is no way I can raise the resolution.
But I really want HD 1080i !
I know my TV can support it, as I can switch my XBMC to 1080i and TV switches to it.
I tried to play with PowerStrip options, without much luck.
Is there any way to achieve my goal?
I have Windows XP Professional SP2.

Laptop is on and plugged into the docking station which is "powered". Connection to monitor / keyboard and mouse is fine, however I'm surprised to see a lower power - plug is soon message. Isn't docking station supposed to provide power to the laptop?

I have recently purchased Dell Inspiron 15R 5521N laptop with Windows 8 Pro. When I try to connect my laptop to an Acer monitor with an HDMI cable, it gives me a no signal error. But when the same laptop is connected to a Philips monitor using the same cable, it works perfectly. As usual I thought that the monitor was the culprit, but when I connected another laptop to the Acer monitor using the same cable it worked without any errors. So where does the problem lie. The HDMI cable is OK, the laptop is also OK as also the Acer monitor?

XPS 16, approximately 2 1/2 weeks old, using a 5100 wireless card.
I'm having ALOT of drop-off issues from my wireless network when my system is unplugged. Sounds really odd, and my system is either set to balanced or high performance when unplugged, but there it is.
When plugged in, I have yet to notice a dropoff. So I'm assuming they are connected.
It'll typically drop for about 2-5 minutes and then reconnect.

Whenever I'm copying files over the network to/from my M6400 Covet, I lose network connection.
I get the 'Limited Connectivity' message in Vista 64. It seems to happen for larger files transfers only.
I have the latest software from Dell already. My solution is to restart the laptop.

BIOS reads the battery health as "Performing normally" and the charge at 100%.
but when I unplug the computer, it doesn't go to battery power, it just shuts off. Like there isn't a battery there.
Bought the battery off ebay, it's not a genuine Dell battery, but it worked great.

new screen/inverter/ backlight installed. NEW screen still black, but visible with flashlight. Went ahead and got ANOTHER inverter off eBay and tried that - screen still black. Haven't ever replaced a backlight, and the operation looks delicate (and expensive to HAVE done) ...
