Yes, via one of the cardbus slots at left rear. I just installed such a card, and my old C600 now sports two USB 2.0 ports (in addition to the OEM 1.1 port in the back). You can also buy cards with four ports, but these stick out about 3/4" from the side of the machine and so may be prone to damage if the laptop is moved about. I chose a flush mount card, so it never needs to be removed.
Note: USB 2.0 ports via cardbus may not provide sufficient power for high-drain components such as audio interfaces, external drives, etc. but will work fine for flash drives and low-drain peripherals.
If you have another display from another computer try hooking it up to the blue VGA port on the back of your laptop. If you still don't get display you have something else wrong with your laptop besides a failed display.
First you need to decide how much you need the high speed hub. If it's one of those "I gotta have it" things, you'll need to add some hardware. Your Dell is a laptop so you'll need to add a PCMCIA USB 2.0 card, but if someone were updating a desktop he/she would use a PCI card. See the related links on this page for more information.
yes i have use this key board with my dell latitude c640 and working fine from USB port and keyboard is an excellant choice if you have good typing speed.
There is no IrDA port on D830.
No.
The Dell D520 does not have a dedicated printer port. It has 4 USB ports, any of which could be used to attach a modern printer.
I do not believe this model of DELL has a firewire port available. You will need some kind of adapter.
yes, it has 2 on the back and 1 on the front
The port speed setting for a modem, controls the speed that the computer communicates with its modem.
yep just plug it in from the usb port from the back.
The speed of a USB 2.0 port varies, depending on the hardware being used. However, the top speed the 2.0 port can reach is 480 Mbit/s.
No, it does not come with a 1394 port, sorry.
