New NEC versa E6300 laptop, not recognizing the logitech wireless bluetooth mouse. Running on Vista. It has recognized it a couple of times, but now won't at all.

Go to your control panel and use the bluetooth detect feature to recognize the bluetooth mouse.

I'm not familiar with this particular model, but I have a Logitech wireless mouse w/ a nano receiver. You say the software recognizes the mouse? Is it functioning at all with the battery in it (a new one preferably). Have you tried setting it up using the Setpoint software? Without more information, I can't really help you. You're saying it's DOA, but at the same time you're saying the software recognizes it, which makes me think there's something going on there. Please write back with more details as to whether or not you've tried to set up the mouse with the software and whether or not it's wireless or not. Thank you.

you have to program it in control panel try that

go to the logitech website. Logitech.com support. give your model #. Download the complete software pertaining to your model and plug into usb the software will recognize the mouse.

I would go in and uninstall the mouse completely and then reinstall it fresh using the Logitech software.

You can get both SetPoint 4.80 and Logitech Connection Utility here...

It does sound like it could be a driver issue or the card itself. You will never get anyone to admit they are to blame. Realteks make good stuff and seem quite reliable. My guess would be the driver as your symptoms are what I have seen before on other brands with driver issues. If its under warranty scream and holler (nicely) and see if they will take it back to "fix" it. Generally they can't and you can get it replaced or refunded. If not you can try an earlier driver as well as keeping an eye out for new ones. Sometimes they fix something minor and cause something major like this. If no driver fixes then you can try replacing the wifi card. See what other brands came with your machine such as an Athera.
Fairly cheap to find on places like ebay and installs much like a ram module. No easy fix for this one I'm afraid.

turn ON your bluetooth with switch hardware in front of your laptop, or side in your laptop.
and press Fn and F...to turn ON. i am not sure with your function key F...
