All of a sudden I lost control of my mouse pad. The indicater will move around but it will not respond. I did add a wireless mouse and it still does the same Dell computer

Have you tried to add a mouse pad under it. I have a capricious mouse myself that has to be on a pad to work fine. If you don't have a pad just try it on a dark surface, no glass that's the worst one...

It can also be a simple battery matter, distance is also important depending of the communication technology in use.

good luck

Go to Control Panel
SEE mouse icon... OPEN this
see if the touch pad is disabled

Try to go to the site Sony VAIO model specofic download latest driver for the touch pad

there are specific setting to enable the pad somehate it some love it but you can sort it out by looking at Control Panel /device manager etc

if USB mouse is working at least you can navigate to find issue

Some laptops have a touch pad between the keyboard and the edge of the laptop. This works like a mouse except you slide your finger around the pad to move the mouse pointer and the buttons next to the touch pad are the left and right buttons.
Other laptops have a small round button in the middle of the keyboard which is a mini joystick and it is used to move the mouse pointer around, it will have a couple of mouse buttons at the botom edge of the keyboard.
You can connect a normal mouse to your laptop, it is mush easier than using the laptop's touch pad or mini joystick.

Your mouse could be defective, but let's try a few things first. Try to remove any wireless devices close to it (i.e. wireless router)or try to plug it in a new USB port. Last thing try to use a very dark mousepad. The laser respond to reflection so any white on a mousepad combined with some sun light could result in a free for all mouse pointer.

hi, ok go into control panel,printers and other hardware-mouse -slow the pointer speed a notch at a time. this should help. good luck,glen

replace your optical mouse that's common problem with optical..

Go into your controll pannel then click on mouse. On the mouse properties click on Touch Pad, then you can change the settings for sensitivity of the touch for double clicking with the touch pad.

have you checked that it is the USB port if it is not in the USB port it will not respond

Not sure if it could be a mouse issue or a surface issue. Some things to keep in mind: 1. Most mice have a "channel" buttof on the bottom used to pair it with the wireless base. Try pressing this a few times to see if you get the desired effect. 2. Surface has a lot to do with quality of the mouse tracking beacon. I suggest dropping $10 on a mousepad. I have a mouse pad with a wrist rest I paid $15 bucks for and even though the mouse doesn't move as fast as on the desk, simple changes in the Control Panel for mouse tracking solved this issue. 3. I am not one to harp on a particular mouse manufacturer but I have had a great deal of good experiences with Logitechs line of mice and keyboards. Hope this helps. D.
