I cannot get my keyboard or my mouse to work with my dell computer. what can i do?


Please add more information to get specific assistance. Are these wireless devices? If wired, do they use USB or PS/2 connections.

For wireless devices, try replacing the batteries and resynching to the receiver. (You may want to check putting the receiver in different USB ports.)

For wired devices, disconnect and reconnect. For PS/2 devices, you will need to restart the computer to check if the devices work. For USB devices, try connecting to different USB ports.

Next step, try using a different keyboard and mouse (that work on another computer (stick to USB or PS/2 to match the current pair)). Try a wired set if the problem is with a wireless pair. If those work, continue diagnostics on the wireless keyboard and mouse. Check if the mouse and keyboard work on another computer. If they don't work with another computer, replace them.

If another USB keyboard and mouse pair don't work in any port, your USB ports may have failed. Check if even one port works enough to access the Device Manager. (Start > Control Panel > Hardware and Sound > Device Manager (Win7); similar directions in other versions of Windows) Check for a problem with the drivers (For USB ports, scroll down to the USB drivers and look for a triangle with a yellow exclamation point or red x). Try to update the driver or roll it back. If that doesn't help and one USB port works, a USB hub may solve the problem.

Otherwise if the USB or PS/2 ports do not work with any devices and the driver fix doesn't work, then I'd suspect a problem with the ports on the motherboard. Replace the motherboard/computer.

I hope this helps.

USB port not reconizing


The time delay depends on the following factors:
  • Host controller hardware
  • Attached hubs
  • Attached devices
  • USB driver versions
  • Support for USB 2.0
  • Additional system hardware or configurations that may change the timing

Method 1: Initiate recognition of the USB device by using Device ManagerTo initiate recognition of the USB device by using Device Manager, follow these steps:
  1. Click Start, click Run, type Devmgmt.msc, and then click OK. The Device Manager window opens.
  2. Click to select your computer as the location for the scan.
  3. On the Action menu, click Scan for hardware changes.

    Windows XP recognizes the new device.
  4. Close the Device Manager window.
If this method resolves the issue, you are finished.
Method 2: Restart the computer To initiate recognition of the USB device, first unplug the USB device and restart the computer. Then, wait five to ten seconds before you plug the USB device into the computer or hub. Windows XP recognizes the new device.

If this method does not resolve the issue, you might want to review the articles in the "Similar Problems and Solutions" section, or contact Support.

My kingston 2 gb flash disk is not recognized, how can i fix it?


Please follow the below steps to fix your problem

1
Connect your flash drive to your computer using an available USB port. If your flash drive is not recognized, you'll usually receive an error that says "USB Device Not Recognized."

2
Click "Start" > "Control Panel" and open the system configuration by double-clicking the "System" icon.

3
Navigate to the "Hardware" tab and click the "Device Manager" button to open the Device Manager.

4
Click the "+" next to "Disk Drives" and locate your USB flash drive. A question mark icon should be shown to the left of the label. Right-click the device name and select "Uninstall."

5
Open the "Action" menu at the top of the Device Manager and select "Scan for hardware changes." This will scan your PC for any new devices. Because you uninstalled the flash drive, it will be detected as a new device and the drivers will be reinstalled.

6
Click "Start" > "My Computer" and look for your flash drive. If this process was successful, your flash drive should now show up under My Computer as a storage disk.

Hope the above information will be helpful to you.
Thanks.

My acer mouse model number mg-0919 stops working after about 2 minutes. I have to turn the mouse off then back on. This happens constantly. What is going on? Is it defective? My mouse is under...


I had the same problem. This mouse came with my Acer Revo which was still under warranty. Tech support basically says to check the obvious (batteries, USB connection, RF interference). Their obviously canned answer goes on to detail a manual reconnect procedure that does not apply to this model. And when all else fails, get a new mouse.
This is what Acer tech support emailed me:
If you are experiencing issues with your wireless mouse not working properly, perform the following steps to troubleshoot the wireless mouse.

1) Ensure that the receiver is 8-inches from other electrical devices. Avoid placing the cordless devices on metallic surfaces.

2) Verify that the USB connector from the receiver is properly plugged into a USB port on the computer. Try plugging the receiver into a different USB port to ensure that the USB port is working properly.

3) Remove the batteries and then reinsert the batteries into the mouse, making sure that the battery polarities are correct.

4) Test the batteries to ensure that they still have a charge.

5) Try the manual connect procedure.

Manual connect procedure:

1) Press and release the Connect button on the receiver.

2) Within 30 seconds, press and release the Connect button on the mouse.

If the issue persists, we can replace your computer's wireless mouse.

We will ship the new wireless mouse within 3-5 business days.

Before placing an order for wireless mouse we would like to confirm the following.

1) Complete shipping address:

2) email address:

3) phone number:

In order to place an order for wireless mouse, the computer must be registered.

I hate this message.
You can use a program like PC Wizard from CPUID that will tell you what all of you pc specs are.

From your specs you may not have usb 2 ports.
Device manager should also say what usb ports you have.

The best ports to use are the ports on the rear of the computer, front usb ports sometimes dont have as much power to drive external hard drives or high drain devices

Sandisk is not being recognized on my computer


SOLUTION 1 - Verify if minimum system requirement is met.
SanDisk card readers support Windows Vista, Windows XP SP2 and Windows 2000 SP4.

For MAC users, see
Troubleshooting USB device on MAC



SOLUTION 2 - Verify the reader's status under Device Manager.

STEP 1 - Connect the reader to the PC

NOTE: It is recommended that you plug your card reader to the back USB port on your PC to ensure that there is enough power from the USB port for the card reader to be detected properly.

STEP 2 - Check under Device Manager
1. Right-click My Computer.
2. Select Manage.
3. On the left pane, click Device Manager.

NOTE: The card reader will appear in two places: Disk Drives and Universal Serial Bus controls as USB Mass Storage. If there is a yellow exclamation point (!) or question mark (?) next to the device, try to refresh the drivers.

STEP 3 - Refresh the drivers
1. Right-click the entry with the error mark, select Uninstall.
2. On the top menu, click Action, and then click Scan for hardware changes.

STEP 4 - Verify if the reader is detected
1. Double-click My Computer.
2. Look for the card reader under Devices with removable storage.


SOLUTION 3 - Try other USB ports.
A yellow exclamation point (!) under Device Manager usually means that the device is not receiving enough power. If the reader is not receiving ample amount of power from the USB port, it may not function properly.


SOLUTION 4 - Change the drive letters

NOTE: The SDDR-89 reader should show 4 drive letters under My Computer.

try one of the method below:
Method 1: Try different ports loadTOCNode(2, 'moreinformation'); Warning If you have to change a PS/2 connection, shut off the computer, make the changes, and then restart the computer. Do not plug a PS/2 device in the PS/2 port while the computer is running.

To determine whether the problem is related to the ports on the computer, use only the two cables that are included with the wireless desktop receiver, or the single cable that is included with a mouse.
USB keyboard and USB mouse loadTOCNode(3, 'moreinformation'); If the USB cable is currently connected to a USB hub, disconnect the device from the hub, and then connect it to a USB port on the computer. If your device is already connected to a USB port on the computer, try to connect the device to a different USB port if one is available.

Note Only one USB connection to the computer is required, even if your device has two USB plugs. If the problem persists, disconnect other USB devices and connect only the USB plug from the receiver to a USB port on the computer.
PS/2 devices loadTOCNode(3, 'moreinformation'); If your devices are connected to PS/2 ports on the computer, verify that you have the following configurations: • Verify that the USB plug for your mouse is connected to the green USB-to-PS/2 adapter and that this adapter is plugged in the mouse PS/2 port on the computer. The mouse PS/2 port on the computer may also be green. If you are not sure which PS/2 port is the mouse PS/2 port, see the documentation that came with the computer. • Verify that the USB plug for the keyboard is connected to the purple USB-to-PS/2 adapter and that this adapter is plugged in the keyboard PS/2 port on the computer. The keyboard PS/2 port on the computer may also be purple. If you are not sure which PS/2 port is the keyboard PS/2 port, see the documentation that came with the computer.If you have to change your configuration, shut off the computer, make the changes, and then restart the computer. If your mouse or keyboard has both USB and PS/2 connections, try using the other connection.
PS/2 keyboard and USB mouse loadTOCNode(3, 'moreinformation'); Verify that the USB mouse is plugged in a USB port on the computer and that the purple keyboard PS/2 plug is connected to the purple PS/2 port on the computer. If you have to change the PS/2 connection, shut off the computer, make the changes, and then restart the computer.

Method 2: Install fresh batteries loadTOCNode(2, 'moreinformation'); Both the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. If the problem persists, install a fresh set of batteries in the device that you are experiencing problems with.
uparrow.gifBack to the top
Method 3: Resynchronize your device to the receiver loadTOCNode(2, 'moreinformation'); To resynchronize the mouse or keyboard to the receiver, follow these steps.

Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put other wireless keyboards and mouse more than six feet away. 1. Press the button on the receiver, and then verify that the light on the receiver starts to blink. 2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen.

Otherwise, go to the next step. 3. Press and release the Connect Channel button on the bottom of your mouse or keyboard. 4. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.

Method 4: Install the latest software loadTOCNode(2, 'moreinformation'); If you are troubleshooting a wireless mouse, download and install the latest Microsoft IntelliPoint software. For more information about IntelliPoint software, visit the following Microsoft Web site:
http://www.microsoft.com/hardware/mouseandkeyboard/Download.mspx (http://www.microsoft.com/hardware/mouseandkeyboard/Download.mspx) If you are troubleshooting a wireless keyboard, download and install the latest Microsoft IntelliType software.

Method 5: Clean the mouse lens loadTOCNode(2, 'moreinformation'); This problem may occur if you are using an optical or laser mouse and the lens on the mouse is dirty. To clean the lens of an optical or laser mouse, follow these steps: 1. Use a dry cloth to clean the bottom surface of the mouse. 2. Check to see whether the mouse functions correctly. 3. If you see dust on the bottom of the mouse, use a can of pressurized de-ionized air to blow away the dust on the lens. 4. Check to see whether the mouse functions correctly. 5. If the pressurized air canister is not available, blow dry air on the lenses by using your mouth one or two times. 6. Check to see whether the mouse functions correctly. 7. If these steps do not resolve the problem, use a cotton bud to clean the lens without scratching it.
