yes i can see a whole lot range of drivers but specifically non is written for bluetooth drivers and still l am not quite sure were the base system device drivers fall into which category too.
Which bluetooth drivers you need, depend on whether you've a 370 or a 410 card. They're under Network drivers.
It's very difficult to say what the other drivers are because it depends on how your system is configured. Be sure you've installed the Dell notebook system software and the chipset drivers (under System Utilities and Chipset). These MUST be installed - they're not optional. Also check to make sure you've installed the security (trusted platform driver) driver, and if you've a fingerprint scanner, that driver as well. There's a Ricoh driver for the card reader as well - see what's missing from the control panel and install accordingly.
