BIOS Beep Codes
Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem. The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (a faulty video card or no card installed) or if an external ROM module does not properly checksum to zero.
An external ROM module (for example, a video BIOS) can also issue audible errors, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that external device.
There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of the screen (using both monochrome and color adapters).
If POST completes normally, the BIOS issues one short beep before passing control to the operating system.

What is the best way to connect 2 computers to this monitor


If you have two separate computers for different purposes, such as personal and work use, you may find it convenient and necessary to connect both to a single monitor. Many monitors have dual inputs, making such a connection simple. However, you might need a keyboard, video and monitor switch to accomplish this task if the monitor lacks a second input. Dual Inputs
Step 1 Examine the back of your monitor for the presence of dual video inputs, such as a single VGA and DVI or HDMI output.
Step 2 Connect the VGA cable to one computer. Plug the other end of the cable to the matching input on the monitor. Rotate the retaining screws until tight at both ends of the cable.
Step 3 Plug the DVI or HDMI cable into the back of the second computer. Insert the other end into the monitor's digital video input. Screw down the retaining screws if you're using DVI.
Using a KVM Switch
Step 1 Ensure both computers are turned off. Place the KVM switch on your desk where it is within convenient reach.
Step 2 Locate the video output port on the back of the KVM switch. Plug a VGA cable into this port. Plug the other end of the VGA cable into the monitor.
Step 3 Plug the VGA monitor outputs from each computer into the inputs on the back of the KVM switch. Tighten the retaining screws down for each connected VGA cable on the computers and the KVM switch.
Step 4 Plug the keyboard and mouse cables into their respective outputs on the KVM switch. Plug each set of keyboard and mouse cables from their ports on each computer into the matching inputs on the KVM switch. Plug each cable in sequentially to avoid mixing them up between machines.
Step 5 Double-check that the mouse, keyboard and monitor cables leading from each computer all correspond to the right machine. Plug the KVM switch's power cord into a nearby AC outlet or power strip.
Step 6 Turn the computers and monitor on to verify the connections are correct.

Required Items

  • VGA cable
  • DVI or HDMI cable
  • KVM switch
  • Power strip (optional)

Where do i connect everything inside the pc?


Be calm, all wires only plug where they belong to and most times they're color coded.

1. Two cables connect to the monitor, one is a power cable and the other is a video cable, most of the times its VGA cable which end in a connector with 15 pins and a blue plastic cover, search for a blue rounded corner trapezoid in the computer tower, once you find it carefully instert the cable from the monitor and tight the screws that are at each side. image

2. If your keyboard and mouse are USB then connect them to any avaiable USB port (these are squared and the computer has many), It may be that your keyboard and mouse end in round conectors this are called ps/2 and look like this, purple is for keyboard and green for mouse.

3. This far you have connected most common input output, if you also have speakers connect its jack in the green audio socket.

Finally connect your computer to the power, this should be all.

My monitor has kicked into sleep mode and won't "wake up".


Unplug all the Cables from Compaq Presario 5103 CL and leave the Keyboard, mouse and monitor cable pluged in.

Now make sure the power cable of the monitor should be pluged in and the power cable of the tower should be pluged in.

Now to check if the montor is fine just unplug the video cable only which will show no input signal on the screen. If it shows this signal the monitor is fine. Plug back in the video cable.

If the monitor is going to sleep mode it might be possible that the old computer ( Compaq Presario 5103 CL ) is in stand by mode. hit any key on the keyboard and it should come back .

If it is not in the stand by mode then do one thing. Check the same monitor with the new computer. If it is working. Perfect ..!

Do one thing now ..!

Unplug all the cables from your old system and then press the power button for 30 sec and let it go. Now plug the keyboard, mouse and the monitor try again.
If it works Perfect. If not ..!

Then you need to open the tower and check on the processor FAN is it running..? If its not running you will not get the display as the fan is responsible for the display on the screen. Otherwise...!

Check the Tower possibly the Tower is not getting the power.

Try these steps and let me know If it works

How's the status light of your computer monitor? is it blinking amber? and the status light of your computer tower's power button? blinking amber as well or solid green or no light at all?

1. Disconnect all the connection at the back of your computer tower
2. Press the power button of the computer tower for 15 seconds
3. Reconnect the power button and the monitor cable at the back of your computer tower and turn on the computer (if it turned on that means that one of the device plugged at the back of your computer tower is faulty)
4. If still the same problem, open up your computer tower.
5. Reseat the video card, Reseat Hard drive, Reseat Memory, Reseat CPU, Reseat power cord coming from the CPU to your computer (doing all things one-by-one to pin-point the root cause of the issue)

If none of the troubleshooting steps fixed the problem, possible that the power supply is faulty and if the power supply is faulty sometimes it goes with the motherboard.

Using KVM-121 with 2 monitors


the way the kvm switches works is you have your mouse/keyboard and monitor plugged into the switch then you have the cables connecting to where you would have your mouse/keyboard on your pc, youll be using the same keyboard/mouse and monitor to run 2 pc's. there will be rather a switch to move between the pc's or like the 1 i use i have tp press ctrl the number 2 twice.

Sounds like there may be more than one problem, so first let's make sure you shut the computer down completely:

1) Press and HOLD the power button on the computer tower until it goes completely dark. A single press often puts the computer in sleep mode, so holding the key for approximately 5 seconds usually forces a power off. After doing that, If you're still not sure if it powered off, unplug the AC power cord from the back of the computer tower for a few seconds and plug it back in. Now, make sure all other cables (monitor, keyboard, mouse) or wireless USB adapters for keyboard and mouse are securely plugged in where they are supposed to be.
2) Press the power button on the computer tower briefly to turn it back on.
3) Everything may be working now, but if not:
a) Monitor still dark? Make sure the monitor is on and plugged in, also, there is often an input source button on the bezel of the monitor to toggle between input sources (such as VGA, DVI and even HDMI). Press and wait a few seconds for a picture, repeat slowly at least 3 times.
b) Keyboard or mouse still not working? If wireless, make sure they have fresh batteries and that the wireless USB adapter is plugged into a USB port firmly. If wired, make sure the cables are plugged in firmly into the correct places on the back of the computer.

If all that fails, your new computer may be faulty and need to be returned to where you purchased it.

Hyundai monitor connects two computers .how do i switch between them?


Use a KVM (keyboard,video, mouse) switch to connect your 2 computers to this monitor. Then you can also have only one keyboard and one mouse. Connecting to the VGA header with one computer and the digital with another is probably not a good idea and the only way that can work is if your monitor has a built in video switch that can be controlled with software. If that is the case they would boast about it in the user manual and tell you how to activate the switch. VGA KVM switches are relatively in-expensive. Some high end KVM switches will exceed the cost of your monitor.
