My dell optical mouse cursor does not move and shows yellow triangle. what is the problem

The cursor operated by the mouse?
Try using the cursor (arrow keys). If they work, try cleaning the mouse ball, unscrews from the underneath, or change the mouse if optical.

If the keyboard is working, try the "tab" key or a combination of the "tab" and "shift,ctl or alt" key.
You should be able to move the cursor to highlight to Ok message, then hit return.

Hello Dear... Mouse cursor don't response, It possible your usb port fail to response because one of your usb drivers is missing ...To find out about it please, check in your setting control panel, click on system then on hardware then on device manager.. it will show a yellow icon ...this icon need to be install or re-install due to corrupt file inside your machine...To fix that problem delete that icon and restart your PC then your pc will ask you to insert you windows CD to re-install the corrupt file for your usb controller..

Hi , your mouse is losing signal too the adapto that you plug into your PC , try putting it close , and change the batteries , this will help
Thanks

1) Is it wireless? Check batteries/re-synchronize.
2) Check the plug/connector at the mouse port on the back of the computer-loose/unplugged?
3) Broken mouse? Try plugging in a different mouse-one you know works.(New optical mice are relatively inexpensive-$10 or so)

If nothing above helps, use ARROW keys, TAB button and ENTER button to move around, and do the following:

go to windows START(lower left corner)
go to system
go to device manager

Now find your device MOUSE (yellow triangle indicates error)

Open your mouse ("Mice and other pointing devices")

On the first Tab GENERAL, it should say if the device is working properly or not.

You can DISABLE the mouse on the second Tab DRIVER, see if he disabled it. (You can enable it.)

Hope this helps.

Do you have an optical mouse, is the light lit on the bottom? try another usb connect in the back of your computer if you have one, try another mouse.

REPLACE THE BATTERY AND UPDATE THE SOFTWARE AND PUSH IN THE RESET BUTTON ON THE BUTTOM OF THE MOUSE SO IT KNOWS WHAT FREQUENCE TO OPERATE AT

Is it corded or cordless?

If your mouse is "locking" the two most likely causes are either due to a battery issue or a connection issue. The first is unlikely since you're saying it started just after you replaced the battery, but you might want to try again if you have other new batteries around that you can use. Also you could try Re-Pairing (if you have the bluetooth wireless keyboard/mouse combo that dell offers) the keyboard and mouse after reboot. step by step Instructions for re-pairing or fixing a corrupted are should be available on the Dell support website and vary depending on the exact model you have.

I just read one of the other solutions, and it was to try and press the reset and mouse reset buttons together - woked for me! yay!
