when i conect my sd to loptop there is no notification that shows it can or cont read the sd... how can in fix this?

How are you connecting it? With a USB reader or the laptop's card reader? If that card works find in another computer, then the issue is with the reader you are using.

Does the card show up in My Computer as a drive letter? You could simply have autoplay disabled which will prevent the pop-up when you insert it.
