A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e., the memory and microprocessor). These auxiliary devices are intended to be connected to the computer and used in conjunction with it. Examples of external peripherals include mouse, keyboard, printer, monitor, external Zip drive or scanner, while internal peripherals include CD-ROM drive, CD-R drive or internal modem. Today's new devices, such as tablets, smartphones and wearable computing devices are considered peripherals as they can be connected and used on a computer system. The difference, however, is that these devices can run independently of the computer system.

I think an old Dell 2709W monitor just died but want to check if I am overlooking anything. The monitor display suddenly became a mess of unreadable, moving colors. I did not take a picture of that but have two others below.

Here is a picture of the monitor's on screen menu:
on screen menu
And here is a picture of the text that moves around the monitor screen while no input is active:
screen saver with no input
The monitor looks the same way when disconnected from any computers and video input cables. The computer to which the monitor was connected when the failure occurred is working fine connected to another monitor.

I cannot read the on screen menu enough to try resetting the monitor to factory defaults.

In your experience is there a way to possibly restore proper operation of the monitor? Or should I stop investing time in it and replace it?

Thanks, Pete
My Logitech Anywhere Darkfield mouse could pair
with its Unifying Usb receiver & work well on my
home Win 7 or Win XP but on my office Win10
laptop, the pairing greys out : see attached

How to fix this issue?

There's applications whitelisting on my Win10
laptop which office support colleague has
whitelisted the Logitech unifying software &
there's no more alert that pops up when
running the unifying software/pairing.

The unifying software is Ver 250:
4,147,600 bytes        Logitech_unifying250.exe

Is there a newer driver for Win10?

By plugging & unplugging more than 10 times,
sometimes, it detects the unifying receiver but
after using a while, mouse will not be detected
anymore (ie moving it will not move the cursor).

Think I've seen in youtube that this Anywhere
mouse could be paired with other receivers?
How can we go about doing this (in case the
Unifying doesn't work).  Would still like to
use this Anywhere mouse as there's glass
surface at home/work.
We have a problem with some old software that will not be updated when we complete the switch to windows 10.  The author will not be making any newer versions of the software.

The old software basically acted as a serial printer.   I need to capture that data and have it converted to a text file and then will have some other software process the data.

Is there some 3rd party software that can receive the serial input and produce a text output?
Apple Airpods microphone is not working with Windows 10 Pro.

After some research I found this response saying the microphone will not work.  This is from two years ago.

Are there any new updates that will allow me to use my Airpods microphone on Windows 10?  

Why do I need this ability?
I use Slack, Skype, Zoom daily and this would be nice to use and not have to resort to plugging in my earbuds to use those apps just so the microphone works.

Additional info:
When I use my Airpods with Zoom I've noticed that I can hear everyone talking through the Airpods, but I believe my laptop mic is still the one being used when I talk.  This is fine.  I can hear people talking in the Airpods and I can still use the laptop microphone.

When I use my Airpods with Slack or Skype I've noticed that as soon as I join a call all audio/mic is killed on the Airpods and I have to stop using the Airpods and plug in my earbuds to be able to talk/hear others on a call.  It would be awesome if Slack and Skype would allow me to do the same as I do with Zoom!

Eg Slack interface when I make or receive a phone call > Settings

No matter what option I choose here in the drop down I cannot get audio in the Airpods, but I have had success getting the laptop microphone to work.
Thank you for reading.
I've tried 3 different brands of inks (for Brother MFC-J680DW) : all of which claims
they're compatible, including 3 from Amazon which won't get detected & would
give message like "try reinstall again": Blake,  IKong & Jarbo.
(I must say Blake's ink won't damage my Brother printer & was successfully
 detected in older models of Brother printers of 5-8 years ago;  actually
 Brother did not build chipsets on those old models at that time)

A local dealer claimed the same & I took my printer to test on
the spot & it failed to detect: he claimed my printer is not made locally & thus
his cartridge can't detect:  well I've bought original Brother cartridges (at four
 times pricier than those compatibles) from eBay Hong Kong & Singapore
online & they are detected.

does it really matter which country the printer & cartridge is made in.

There are still a few brands in Amazon including Inkjetcorner & Vmosgo:
anyone know if they'll work with MFC-J680DW ?

One way is I drill hole in original cartridges & use syringes to transfer
over but this often results in drips/spills : very messy
I am looking for a 2-in-one laptop where the keyboard that comes with it, will still function in fully "detached" mode.

In order for the OEM keyboard that the laptop comes with to function in fully detached mode, it would have to have batteries and be chargeable from the laptop itself, as opposed to an add-on cable.

Assistance in finding this would still be greatly appreciated.
My Surface Pro 4 will not display on our new Insignia TV (not a smart tv).  
My iPhone and my partner's Surface Book 2 will both display on the TV, so I know it is not the HDMI cable.
I checked and my Windows 10 is up to date, as is the graphics driver.

When I connect the Pro 4 to the TV, there is a momentary recognition of the HDMI input and the display resolution on the TV, then the TV display says No Signal.

As far as the Pro 4, one of three things happens:
1.  The screen goes black.
2.  Mouse and keyboard are nonresponsive but keyboard is lit; touch screen in unaffected
3.  Mouse and keyboard  are nonresponsive and the keyboard is not lit; touch screen is unaffected.
Control of the keyboard does not return until Pro 4 is disconnected from TV, plugged back into Surface docking station, and power cycled.

In Display Settings, the Pro 4  will not detect the TV. In Advanced Display Settings, it sees the Insignia TV but does not display to the Insignia.

Going to tablet mode seemed to make no difference.

I have usb device which I don’t know if it’s memory or what it is.  I have placed a picture below see if anyone can say or how can I identify what is it? What should I look for? Thank you.

Logitech Keyboard K350 I have been to the site and looked up solutions tried them all. The board is only 5 years old. THE ONLY thing I did unusual is disconnect the cables took my computer outside and with an air compressor blew out the dust and cat fur...! Put it back the unit came back up and unfortunately the keyboard and my Logitech M570 stopped working. So I went to the closet pulled out the old PS2 keyboard and fortunately was able to type this message spent about 2 hours on it last night following all the rules and nothing so far. Does anyone here know what I can try. Again nothing changed but the dust cleanout........frustrated.....!ARRRR!
I have been here to downloads at Logitech the drivers and update software. Restarted No Change.
And here with many other pages too long to list here.


Any help is greatly appreciated. Thank you.
Any recommendation on All-in-one computer for a small construction bussiness?  My buds 12 years old computer died finally :)

Would this be a good option?
Basic use.  Office, quick books, etc.  And he even storing files on local HDD.

Or any other suggestions?
Hi there!

I'm currently working with an HP LaserJet Enterprise M506 printer with a client and we've been having repeated issues with black streaking occurring across the page each time we attempt to print out a document. I've attached a scanned PDF document of a printed page from this printer for context.

We've already attempted to replace the ink cartridge as well as the drum, however the issue is repeating past both of these changes. For the ink cartridges, the client is using a Premium Imaging Cartridge CE255X.

Does anybody happen to have any ideas as to why we're not able to get these streaks to go away? Is it just a matter of using a genuine HP ink cartridge instead or does something else need to be done here?

Thank you for your time!

I have speakers plugged in and recognized because audio is playing out of them on the 3.5 mm audio (headphone) port on my windows 10 pro tab.  However these speakers are not appearing in the playback tab of the "Sound" setting of the control panel nor are they found in either "Sound, video, and game controllers" or "Audio inputs and outputs" of the control panel.

What is found under:

Audio inputs and outputs:
Microphone (Intel SST Audio Device (WDM))
Speakers (Intel SST Audio Device (WDM))

Sound, video, and game controllers:
Intel SST Audio Device (WDM)
Realtek I2S Audio Codec

Playback tab of the Sound setting in the control panel:
Speakers Intel SST Audio Device (WDM)
Default Device

Also, none of these settings change when these speakers are plugged into this 3.5 mm audio (headphone) port.

What I would like to do is, using Visual Basic 6.0,  when a command button is clicked (cmdSound1_Click()), have a message (msgbox) that reads simply if there is a device installed in this  3.5 mm audio (headphone) port.  For example "Hardware found in audio port" or "No Hardware found in audio port, please be sure that the speakers are powered on before trying again."
I have two Microphones connected to my Windows 10 Pro (64-bit) box.

One is built into my Web Cam ( Microsoft LifeCam Cinema ) and what I've been using up until now.

Recently I purchased a much higher quality USB Microphone that does a significantly better job at filtering out background noise.

Sometimes though, I still want to use the built-in Microphone in my LifeCam Cinema WebCam.

I know how to make the change via UI methods, but it takes too many clicks for my liking, so wondered if there is a simpler way to achieve the desired result?

Change Default Mic in Windows 10 using a script of some type.
So... what I need is a batch file, script or Powershell command way of telling Windows 10 which Microphone to use by default. Something I can double-click on my desktop which will result in all of the needed changes to be made to make one or the other Mic the default in Windows 10.

Please note that I am heavily challenged when it comes to any type of coding, scripting or automating. A programmer I am not.

Using a GUI I can figure out how to do just about anything on Windows, but if I need to make changes via Powershell or similar, please include detailed instructions on how, where and why I need to run the script(s), and if doing so will have any negative effect on Windows 10 security.  It's why I stay away from using PowerShell unless an expert in it tells me exactly what to do and why! <g>

With all that said, can anyone offer a solution?

Regards, Andrew
I have Power Supply and Motherboard from HP Z420 workstation. I bought a case for it: Corsair 275R. The problem is that HP's PSU will not fit there at all and even if it did, the CPU cable would not reach the top of the motherboard where it is supposed to be plugged. So I have a new PSU: Corsair VS550. The problem is that ATX and CPU plugs are different on HP's power supply and Corsair's one. See attached pictures. Does it mean that HP is custom that I won't be able to get PSU for that motherboard or I can't use that specific Corsair I have and have to get something else? or am I missing something else?

Thx in advance
I previously used a Logitech headset with microphone combination for recording voiceover narrations for training videos.  The one I have been using broke (USB dongle broke).  Does anyone have suggestions for a new one? (reasonably priced of course).
I am looking for a switch which, when turned on, automatically switches off after a predetermined time like 1 minute or two minutes. The application is a door light which is turned on when someone rings the doorbell.

What would such a switch be called.

Any link would be welcome from which I can purchase it. Ali Express is preferred as it definitely delivers to my country.
I am looking for a wireless mouse and keyboard that will work through walls at a distance of at least 40 feet.  Are there any models available that will do so?

Are you thinking about creating an Amazon Web Services account for your business? Not sure where to start? In this course you’ll get an overview of the history of AWS and take a tour of their user interface.

Everything that comes out from our HP M227fdn is powdery. We leave it sitting to maybe dry but it doesn’t help and if the printed area is touched the ink smears. Any ideas as to why this is happening?
Hello - we have a Surface Pro 2 that has a problem with the USB port not working.  It has been working ok for about a year now, but suddenly stopped working.  only the Sufae cover-style keyboard and mouse work for peripherals.  I have updated the unit to the latest Windows 10, but there are some updates waiting, which I am installing right now.  when I check Dev Mgr, nothing is in an error state, and it appears that all drivers are installed and OK.  what would cause the USB port to stop functioning?  looking for some help on this.

Please provide me with the FRU # to purchase a replacement built-in keyboard for a Lenovo T450 20BUS05B08 laptop.
We have a couple of old Lexmark 2500+ series dot-matrix printers still in service that are used to produced shipping labels, one or two or ten at a time. These printers have a horizontal metal shaft and the printhead slides back and forth on that shaft, driven by a motor and cogged belt. One of these printers has started to malfunction and as best I can tell it's because the printhead/shaft mechanism is in need of some lubrication. If you slide the printhead manually, you can feel resistance. Cleaning the shaft with rubbing alcohol seems to provide a temporary fix. Once upon a time, I was told that printers of this type should never be oiled as it would ruin the bearings in the printhead mechanism. However, according to the service manual on this Lexmark this one should be lubricated when certain parts are replaced, including the "oil felt (carrier block)". It further goes on to say that only mineral oil based lubricants should be used and gives a Lexmark part number 1280443 and these approved equivalents: Mobil DTE27, Shell Tellus 100, Fuchs Renolin MR30. My questions are, should I be lubricating this printer even though I'm not replacing any parts? Secondly, I'm having difficulty finding the specified lubricants in any size other than 5 gallon containers, costing over $100 each. These all appear to be "anti-wear hydraulic oils". Am I obsessing too much trying to find the exact spec oil or can I get by with something off the shelf, as long as it's mineral oil?
I installed a newer nic in my win 10 pc and it isnt installing.
