Dell monitor turns off its USB Ports as well

 

I’ve been using this 22’’ monitor (SP2208WFP) for more than one and half year now. Its great one with inbuilt webcam, mic, usb ports etc.

However, only drawback I found is when I turn off monitor, it turns off its USB ports as well. This is not expected behavior. I’ve attached my USB mouse through monitor. But when I turn off and turn on monitor again, my mouse doesn’t work and I have to re-plug it.

In another example, let’s say you’ve attached external hard drive to the monitor and some bulk data transfer is going on that drive. You just want to go away for some time, and you naturally turn off monitor... wham!! That turned off USB drives and consequently your external hard drive as well. Just turning off monitor could thus result in data corruption.

Any idea if this serious issue can be addressed?

The USB ports must have the monitor on to function. That is by design. The mouse and keyboard should never be plugged into a monitor. They should be plugged directly into the PC.

In theory, USB ports must have CPU on to function. Monitor button could have turned off only display (which is desired most of the time). Turning off any USB ports abruptly is definitely not recommended.  Could be a design flaw.

* Nope. It is a design choice.

Re: Dell monitor turns off its USB Ports as well

The following is for the U2211H dell monitor, wich also has the same problem,(accidentally or wanted, flaw design or design choice, whatever), In the Dell ultrasharp U2211H page:

http://accessories.us.dell.com/sna/products/Displays/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku=320-9271

go to:

+ More Images of UltraSharp U2211H Monitor

and select the image which show you the monitor ports.

There It clearly says:

With four USB 2.0 hi-speed ports, you can easily connect a keyboard, mouse, webcam and other peripherals. Other peripherals, could mean, let see a simple and commonly used pendrive. Well, let say that i have a 8 gb one, very common this days, and i'm transfering files to the pendrive, 8 gb takes a considerable time, so meanwhile i may go wherever i want, and so, i turn off the monitor, OH my god, DATA CORRUPTION. Turning off the monitor is exactly the same as disconnecting the pendrive abruptly from the USB port.

First, I don't appreciate the personal attack! Next time, I will delete your post.

Second, that statement is from marketing, not technical support. Do you honestly think a marketer is going to know the technical reasons to not do something?

Re: Dell monitor turns off its USB Ports as well

It clearly means Dell marketing and tech support doesn't agree with each other on what they claim or say. Which further means Dell cannot support what their marketing department tells their customers at the time of selling products. Now listen, "abruptly turning off USB devices to the system" is NOT recommended, and that’s for sure. We must have to accept it. If your monitor doing it, then its clearly a defect. If you saying "It's by choice" I would like to know from your designers what made them to make such a defective "choice".  It’s very easy to avoid such malfunctioning in the design.And yes, nothing personal here. We are customers we pay from our pockets on the basis of what marketing guys tells us. and thus DELL get business and you get salaries.

* Sales persons are only trained in the minimal specifications. No one would have ever thought of a user actively transferring data through the monitor USB port would power off the monitor. That just does not make sense.

Which further means Dell cannot support what their marketing department tells their customers at the time of selling products.
* I cannot speak to what Sales/Marketing say or do. I speak for Technical Support.

Now listen, "abruptly turning off USB devices to the system" is NOT recommended, and that’s for sure. We _must_ have to accept it. If your monitor doing it, then its clearly a defect. If you saying "It's by choice" I would like to know from your designers (and not from you) what made them to make such a defective "choice".
* It is by design that if you cease power to the monitor, the USB ports built into the monitor will turn off.

It’s very easy to avoid such malfunctioning in the design.
* It is not a "malfunctioning in the design".

And yes, nothing personal here. We are customers we pay from our pockets on the basis of what marketing guys tells us.
* Agreed.

and thus DELL get business and you get salaries.
* Agreed.

Re: Dell monitor turns off its USB Ports as well

Yes, I attacked you because you attacked . I thought, why this guy was answering in such a way? I only posted because of that, i'm not being affected by this BAD design, i don't need to use the usb ports regularly.  question was completely understandable, what you said was like: "I don't care what you think, we design our products as we pleased". There are a lot of ways to be rud, not only a direct attack. You don't need to be actively transfering data. Just use it once in a while, to transfer data to a pendrive, if it is a 8 gb one (ever worst a 32 gb or more) it takes long to finish the transfer, but Why you would need the Monitor to be turned on while you are transfering data? What kind of design is that?By the way i have an AOC monitor that doesn't turn off the usb ports when the monitor is turned off. But i could tell you why this is designed like this, the monitor has a bus-powered hub, so if you want the ability to turn off the monitor and leave the usb port on, you need an extra power circuit with eventually an extra power button for the usb port, and that is more expensive that no having one. I don't buy the products to the technical support, i buy them from marketers, and i have no other means (except web reviews) to decide what product to buy that believe what is stated in the company's web page. Maybe you the "technical stuff" need to work in conjunction whit marketers to guarantee that what is marketed is Real and not a marketer invention. You should, you are selling what is stated in Dell site, i'm, personally, not talking about what the seller says at the moment of selling the products, i'm talknig about facts, i'm talking about what is stated in DEll site, see the above post.
