1. Make sure the video cable supplied with the panel is tightly secured to the video card in the computer.
2. Check video cable to ensure all pins are straight.
3. Check the user's guide to see if any special conversion connector or adapter is required for proper signal continuity between the video card and the LCD

• If any of the red, green, or blue colors are missing, check the signal cable to make sure it is tightened correctly. The pins in the cable could be loose and cause a bad connection.
• Check video cable to ensure all pins are straight.
• Try the LCD with another computer.

• Turn the system off and reseat the memory module.
• Turn the system off and install the Nspire memory module in the first socket.
• Turn the system off and install the Nspire memory by itself.
• Check to make sure all expansion cards are fully seated. Expansion cards can pop out of the socket while memory is being pushed into its socket.
• If you don't hear any hard drive activity and no LED lights are lit on your computer, it's possible that you may have inadvertently disconnected the "Ribbon Cables" inside your system. The gray ribbon cables must go back in a particular order. If they have been installed backwards your pc will not boot properly or not at all. The red edge (typically red) of the ribbon cable indicates pin 1 and has to be aligned with pin 1 of the socket. Please look very closely at the edge of the cable socket on the motherboard to find out which is pin 1 or consult your system's manual.
• An ATX12V or SFX12V with the 2x2 connector is required for all Pentium® 4 processor based Intel® Desktop Boards. Power consumption requirements for high-end video cards, sound cards, peripherals, and the Intel® Pentium® 4 processor will exceed the typical 5A current capacity of standard ATX & SPX power supplies. The ATX12V and SFX12V power supply design guides (http://www.formfactors.org/) recommend a minimum of 8A at 12Volts to properly power any Pentium 4 processor based Intel® Desktop Board. Standard ATX and SFX power supplies typically provide approximately 5A of current, which is not capable of reliably powering the Pentium 4 processor based Intel® Desktop Board.
• Verify that the module was installed correctly and that the module's specifications match those in your system owner's manual. If the memory is installed properly and the specs match those set forth in the owner's manual, the module may be bad and should be returned to the place of purchase for replacement.

WARNING! Installing a memory module backwards may cause damage to your memory module and or system board.

There are a few things you can do, too, to extend the battery life of your mouse. First, make sure you use the alkaline batteries; rechargeable batteries do not last as long as alkaline ones. Second, use the mouse on a light colored surface such as a sheet of white paper. Darker surfaces force the LED on the underside of the device to shine brighter, which requires more battery power.

Note that the light on the underside of the mouse will always be on as long as batteries are installed. This is necessary for the device to work. The only way to completely turn off the mouse is to remove the batteries.

Many things can cause an optical tracking device to have erratic cursor movement. Possibilities range from surface to hardware problems.

Solution

• Surface
  The surface on which you use the mouse plays an important role in its tracking. The optical sensor must use the pattern on the surface to track the position of the cursor. Therefore, using the mouse on a glass or otherwise see-through surface will inhibit the ability of the sensor to track the cursor. Also, if you are using the mouse on a reflective surface, such as a mirror or shiny metal desk, you may also experience tracking problems. In both these situations, try using the mouse on a mouse pad or piece of paper. By using the mouse on a white sheet of paper, you can also conserve battery life. Other surfaces that have been known to cause tracking problems are:
  1. Some wood grains
  2. Grooved surfaces
• Trackballs
  The ball in trackballs is held in position inside the ball cage by three ball bearings. If one of these bearings becomes dislodged or is missing, the ball will not rest evenly and the tracking will be affected. To see if this is the problem, remove the ball from the ball cage. (This may require removing the retainer ring or simply pushing it out.) Inspect the ball cage and look for three tiny bearings. If one or more is missing, please contact Nspire customer service.
• Cordless
  If you are using a cordless optical device, there are extra variables that might affect the tracking.
  1. Batteries: Low or dead batteries can affect tracking. Try replacing the batteries with a fresh set and test the tracking. Although you can use rechargeable batteries, alkaline batteries have been found to have the longest battery life. If your mouse is rechargeable, verify you have a good charge.
  2. Interference with other electrical products: Other electrical devices may interfere with the radio signal that the mouse uses to communicate with the receiver. Try placing the receiver in a different location, away from the monitor, zip drives, and other electrical devices. Also, try rotating the receiver so it is on its side (or back). If you are using a dongle receiver on a notebook try moving these other electrical devices away from the receiver.
  3. Range of the receiver: Nspire cordless pointing devices can transmit a signal up to six feet and more with some of the newer cordless devices. Try moving the receiver and mouse to different positions (eg side up, side down, to the left a little, to the right, etc.). Try experimenting with different locations to see if that helps.

In general, a Nspire pointing device should work once it has been connected to either the USB port or the PS/2 mouse port. Note: Do NOT connect to the PS/2 mouse port (round 6 pin connector) while the system is powered on, as this may damage the system port, mouse, or both. Always do a safe shutdown of Windows and power the system down. Then connect the mouse and restart the system. Connecting the mouse to the USB port while the system is on (hot plugging) is OK.

After the device is connected, Windows should display a message that states "New Hardware Found". If Windows does not detect a mouse on the system, or the pointer does not move, or the pointer behaves erratically, it can be caused by any of the following hardware issues.

• A port specific pointing device connected to the wrong port. For example, a USB only mouse connected to a PS/2 mouse port. You may want to verify the box package under "System Requirements" to see if the system port you are connecting to is supported.
• Using a non-Nspire adaptor or an Nspire adaptor on the wrong mouse. Some Nspire mice are port-specific (USB only) and won't work while connected to certain ports, even with an adaptor.
• Cordless Users only: In some cases the cordless receiver is detected correctly and all that is needed is to re-sync/connect the receiver to the mouse. First, verify you have fresh batteries installed or, if your device is rechargeable, that is has a good charge. Next press the connect button on the receiver, and then press the connect button on the button of the mouse. If the mouse still does not function or the pointer does not move, continue with the rest of this document.
• A disabled, defective, or incorrectly configured port. Test the mouse on another system if possible to see if it is the mouse or the port that is the problem. Or try another mouse in the same port to see if fails as well. If so, contact your system vendor for information on how to configure your system ports.
• A defective pointing device. You can verify this by trying the pointing device on a second system. If the device fails on another system, please contact Nspire Customer Support to inquire about a warranty replacement.
• A basic compatibility issue with Nspire hardware and the system port. You can identify this by trying another mouse connected to the same system and port the Nspire mouse was connected to. If a second mouse fails on the same port, the problem may be with that system or port. Please contact the system manufacturer for troubleshooting system port problems.
• Use of a switch box, extension cable, port replicator or docking station. Nspire does not support the use of these devices with our pointing devices. If you are using a switch box, extension cable, port replicator, or docking station, please remove it and try connecting the pointing device directly to the system to see if this has any effect.
• USB mice connected to a USB hub can be connected directly to the systems USB port to verify the hub is working correctly. Also trying another USB port if you system has one.
• A hardware conflict with another device in the system. (More common with Serial devices).

Solution

If you have verified the mouse and port are functional mouse is not still not detected properly or does not function, please use the following steps to check the Mouse icon under the Device Manager.

For these steps, we assume there is no second mouse on the system and that you are using keyboard commands. Otherwise you can try to use a second mouse to perform these actions.

1. Press Control-Esc or press the Windows key on your keyboard to bring up the Start menu.
2. Using the up arrow key, highlight Settings.
3. Right arrow key to Control Panel and press the Enter key.
4. Use the arrow keys to highlight the System icon and press the Enter key.
5. Use the right arrow key to select the Hardware tab. (Windows 98/Me users, select the Device Manager tab and skip to step 7).
6. Use the the tab key to select the Device Manager button and press the Enter key.
7. Use the Tab key to select the Computer icon at the top of the list of device icons.
8. Use the down arrow key to highlight the Mouse icon.
9. Use the right arrow key to open the mouse icon and verify there is an icon that states, HID-compliant mouse, and another entry that states the name of your USB device. Or a mouse icon that states PS/2 compatible mouse.
10. If there are any errors reported on these icons by exclamation points or red X's, highlight these icons using the arrow keys and press the ALT-A keys. From the Action menu, highlight Uninstall and press the Enter key. (Windows 98/Me users, highlight the icons, Tab to the Remove button and press the Enter key.) When the Confirm Device Removal box appears, press the Enter key.
11. Repeat until all mouse icons with a conflict have been removed.
12. Press the Alt-A keys. From the Action menu, select Scan for hardware changes and press the Enter key. (Windows 98/Me users, use the Tab key to highlight the Refresh and press the Enter key.) This will allow Windows to re-detect the pointing device.
13. Use the arrow keys to open the Mouse icon again and verify that there are no errors reported.
14. Power down the computer system and restart Windows.

Next, check to see if you are experiencing a detection issue.

If none of this applies and the pointing device has just stopped working, try the device in another port. If you were using it on the PS/2 port, try moving it to the USB port if you mouse supports it. If you have another USB port, try that other port. If you were connected through a hub, try connecting directly to the system ports to verify the hub has not failed. If the device doesn't work on a second port, try it on a second system, if possible. If it fails on a second system, then the device probably is defective. You may also want to try a second mouse in the same port that the failed mouse was using. If the second mouse works in the same port, then you know the Nspire mouse is defective. If this is the case, please contact Nspire Customer Service to inquire about a warranty replacement. If the second mouse does not function in the same port, verify the system port has not failed. Contact the system manufacture for more information on the status of the system port.

• Button is difficult to press or makes a strange noise when pressed.
• Button no longer gives a soft click sound when pressed.
• The system does not respond when the button is pressed or responds intermittently.
• Button must be pressed very hard to get a response.

To verify if the mouse button has failed, please try this mouse on a second system if possible, or try a second mouse on the same system to see if the issue changes. If it fails on another system, please contact our Customer Support for a possible RMA replacement.

If it works on another system, try removing our software by going to the Windows control panel and launching the "Add/Remove" icon. From the list of installed programs find either and click the "Change/Remove" button. Follow the on-screen instructions and restart the system. Verify the issue is now gone. Restart the system and test the mouse to see if the button is still failing. If so, contact our Customer Support for a possible RMA replacement.

1. The most obvious cause is that you've neglected to plug your telephone line into your modem. Double check to make sure. Or the telephone cable may be bad -- test it on a regular telephone.
2. A common problem is plugging your telephone line into the wrong jack on your modem. Many modems have two jacks, one for the telephone line and one for a telephone handset. On some of these modems (e.g., USRobotics), you won't be able to get a dial tone or otherwise use the modem if you plug the telephone line into the telephone handset jack. Double check to make sure.
3. Another common problem is that some other device on the same telephone line (e.g., a telephone answering machine) is off-hook. Double check to make sure that all other devices are on-hook.
4. There may be a problem on your telephone line. Make sure that you can get a dial tone on a telephone handset connected to and through your modem when the modem (or computer in the case of an internal modem) is turned off.
5. Many voicemail systems use a "stutter" dial tone or beeping when you pick up the phone to indicate that you have voicemail waiting. These unexpected sounds can make the modem think there is no dial tone. If you must use the modem on a line with these voicemail or similar sounds, you can try the following workarounds:
   • Increase the amount of time that the modem waits for dial tone by setting the number of seconds to wait in register S6 (e.g., S6=5).
   • Lower the Xn setting to an odd number value to make the modem ignore dial tone and dial blindly (e.g., X3 instead of X4, or even X1).
6. Your modem may not be designed for the phone system in the country in which you are trying to use it. As a workaround, try lowering the Xn setting as described above.

• If you have Call Waiting, the incoming call "beep" may sometimes (but not always) disconnect you. To avoid this problem, you may be able to temporarily disable Call Waiting when you make a data or fax call. (See "How do I shut off Call Waiting?")
• If your modem fails to negotiate error correction (V.42/LAPM or MNP4), the uncorrected transmission errors may make the remote site hang up on you. To avoid this possibility it's a good idea to force error-correcting connections; that way if the negotiation of error correction fails, the modem will fail to connect, and you may be able to configure your software to retry the connection automatically. In Windows 95/98 you can go to Properties | Connection | Advanced and check the Required to Connect option; otherwise, check your modem documentation for the correct option to set in your modem initialization string.
• Disconnections may be caused by momentary drops of DTR by certain comm applications. (By default most modems respond to a drop of DTR by hanging up.)
  • With most modems you can work around this problem by disabling DTR (i.e.,&D0). Note that when DTR is disabled you have to escape the modem to command mode and use the "ATH" command to hang up.
  • With USR modems you can also use register S25 to work around the problem (e.g., S25=10 will ignore a DTR drop of less than 10/100 or 1/10 second, which is twice the default of 5/100 second).
• For those experiencing disconnects (and/or erratic connection speeds) when calling Rockwell-based V.FC modems from a USR 28800 (V.FC or V.34) modem, a firmware fix is now available for the Sportster (dated 4/18/95 or later for USA modems) by calling USR (847/982-5151); for the Courier, the fix (dated 7/5/95 or later for USA modems) is available by FTP. In the meantime, the author's workarounds (which may help in some cases even if you have the updated firmware) are:
  • Disable V.42 Detect Phase (i.e., S27=48).
  • or Disable V.42 completely (i.e., S27=32). If you then sometimes get non-error-correcting connections, force error-correction mode (i.e.,&M5). You may find that you have to redial several times to get connected; if so, try the following.
  • Disable the highest symbol rates (e.g., S54.5=1S54.4=1S54.3=1). This will limit your top speed (to 24000 in this example), depending on how many symbol rates you disable (3429, 3200, and 3000 in this example). also
  • With V.FC-only firmware (as opposed to the newer V.34 firmware) it may help to also disable the 32S-2D map (i.e., S55.2=1).
  • -- finally -- It may also help to set S10=255.
