I have got a Dell Inspiron N5110 which I purchased in January 2012.
The problem I have with it is that, when I close the lid and then reopen it a maximum of 5 minutes later, the cursor is VERY erratic and, if it does move, it dosen't follow my finger. If I leave the lid closed for any longer, the touchpad becomes unresponsive. The only way I can get it back is to use the Windows key on the keyboard and then use the arrow keys to restart the laptop.
Is there anyway I can stop this from happening with the touchpad?
