Peripherals

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.

It started not too long ago. It was at first annoying. My keystrokes seemed to be randomly generated, not the ones I typed on the keyboard. For some reason this only happened in certain applications (especially browsers such as IE11, Firefox and Chrome), but not in others and in some applications only when I typed too quickly. What was, I thought, the oddest part of the whole thing was that the characters were random, in that if I held down a key it would generate a succession of characters, all different, one of which would eventually be itself. Odd....

I was immediately suspicious. Could this be malware of some type? Maybe a keylogger? I am fairly strict when it comes to my production machine and what I allow on it. I have multilayered security installed and several protection apps that work together to protect me from all kinds of malware. So what was happening? I scanned with everything under the sun.

SOLUTION!! (when I first typed that it was totally unreadable)

It turns out that one of my security applications, HitmanPro.Alert, has a setting that is called Keystroke Encryption.  It is to protect you from keyloggers. When it is turned off my typing looks like this, but when I turn it on my typing looks like this: ywsrc2utfsbqi8d4mj62a2hsm5 (I typed "my typing looks like this ").  So if you run into this - check to make sure it isn't this app (now owned by Sophos, not Surfright, and called HitmanPro.Alert/cryptoguard/InteruptX)

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

If you are having problems installing printer drivers, or if documents repeatedly get stuck in the print queue even after re-installing the printer drivers, then follow these steps to solve the problems. Please note that the steps are shown both for solving problems on Windows XP 32-bit and Windows 7 64-bit computers; but they may also work for Windows 7/Vista 32-bit or 64-bit systems.

1.

Delete documents stuck in the print queue, then delete the printer itself (you may need to be logged on as administrator to either clear the print queue or delete the printers).  

2.

If you cannot delete documents in the print queue or delete the installed printers, even when logged on with admin privileges, then follow these steps:
a) Stop the print spooler: Click start, click on Run (for Windows 7 just start typing in the box that opens when you click the start orb). Type Services.msc then press “enter”. In the services window look for and right click on the print spooler, and select stop. Leave services window open, you can minimize it if you want because you will need to go back into printer spooler services again.
b) Open up Windows Explorer and type the following in the location bar: &windir%\System32\spool\PRINTERS and delete everything in this folder. Caution: Do not delete the PRINTERS folder; just delete the files inside the folder.
c) Restart the print spooler: Click start, click on Run (for Windows 7 just start typing in the box that opens when you click the start orb) Type

I recently purchased an HP EliteBook 2540p notebook/laptop. It has two video ports on it – VGA and DisplayPort. HP offers an optional docking station for the 2540p that also has both a VGA port and a DisplayPort. There are numerous online reports documenting that the docking station can drive two monitors simultaneously (obviously, one via the VGA port and the other via the DisplayPort), but I could not find anyone reporting that the notebook itself (without the docking station) can drive both. So I decided to give it a try. Here are the results.

The one word answer is – YES! Running 64-bit Windows 7 Professional (this is the standard, bundled OS for the 2540p), I tested it in two different setups. The first consisted of a Dell 2707WFP 27" flat panel LCD monitor (connected via VGA) and a Dell 2709W 27" flat panel LCD monitor (connected via DisplayPort). The 2540p drove both at 1920x1200 resolution and 32-bit color (in an extended desktop configuration) with excellent performance. The only downside is that the notebook cannot drive the built-in LCD at the same time. I experimented with it for a while and found that it can handle just two displays at a time, not three. So it can drive either both of the external monitors or one of the external monitors and the notebook LCD. I happily gave up the 12.1", 1280x800 notebook display for the 27", 1920x1200 monitor.

Neither of the Dell monitors has built-in speakers, so I was unable to test whether …

Two updates to this article: (1) I tested a DisplayPort-to-DVI-D adapter and it does, indeed, work, as discussed towards the end of the article. (2) One of the articles on my to-do list is about a video adapter/converter (known as as "active" adapter) that allows three monitors (or two monitors and the built-in display) to work on some laptops in some configurations. However, I tried it on the HP EliteBook 2540p, both on the laptop itself and on the VU895UT Docking Station, and with a DisplayPort-to-HDMI active adapter in one test and a DisplayPort-to-DVI-D active adapter in another test – none of the four tests was able to get the built-in display working at the same time as the two external monitors.

Well I am not sure whether i deserve anything (credit or points) for this article, since I have not written the source code but discovered the same while browsing the net. I only wish to help EE users save some money and probably help the environment (for whom it is important of course).  Please note that I have used this utility personally and benefited from it, so i wish to make the solution more widely available.

The article is based on the following link:

http://www.indiabroadband.net/computer-hardware-software-tips-tricks/14122-most-common-problem-optical-mouse-solved.html 

The source code is available there.

Have you ever faced a problem with your optical mouse (any brand - specially the less-expensive ones like: Techcomm, Frontech, Zebronics etc)?  After usage of 7-8 months (the duration differs) many optical mouse users face a problem of multiple clicks (2 or more than 2) on clicking just once.  It becomes really hard to control the mouse clicks while browsing.  Before you dump your mouse, wait there is a solution to this very common problem.

Well, after searching for solutions on many sites I finally found a solution.

Mousefix.exe is a very small free application which you will need to put in your startup folder and which will always run in the background in case your mouse is having the problem.  It will monitor your mouse clicks and won't let it make false clicks.  For interested people, the entire source-code is also freely available.

To Enable Full Function of the Microsoft Office Keyboard (RT9450) in Vista 64 and Windows 7

These instructions worked for me using IntelliType v 6.1, but later versions of IntelliType might also work.  These suggestions work on Vista 64 bit, but I did not test them on Windows 7.  Other sites have suggested that they will also work on that OS, however.  Success requires the use of AutoHotKey (AHK), a free open source program that is downloadable from: http://www.autohotkey.com/.  This is advertised as a "Free Mouse and Keyboard Macro Program with Hotkeys."  

Using this program, a user can discover what key codes are being sent by various keys on the keyboard.  For example, the "Word" key sends 113.  The "Excel" key sends 114.  In "AutoHotKey" terminology, these would be addressed as sc113 and sc114  (sc stands for "scan code").  The ScrollWheel also can be addressed and modified by AHK.  Since the standard installation of IntelliType can enable many of the Microsoft Office Keyboard buttons without modification (e.g., "Web/Home", "Mail", and others), the only remaining keys that did not function according to my wishes were the "Word" and "Excel" keys since I have elected to use OpenOffice 3.1 on my computer.  If MS Office were installed, these two keys might function as expected.  

The "Microsoft keyboard" icon that is installed to the desktop by IntelliType allows the user to program many of the keys, which might not function as "advertised" without depending upon …
