Mateusz,   It looks like it's an empty slot.     Rick
Hi I'm form Poland and my English is very poor so please bear with us. I bought my notebook Dell XPS L501x about year ago, and i had to do a format of system disc "C". I installed all drivers, and nearly all things works super, but not Dell Wireless 5620 EVDO-HSPA WirelessMini-Card or Dell Wireless 5540 Mini HSPA, becouse i dont't know which is a modem to sim cards. I installed drivers to this modems, but when i put a card to slot, and run a computer, program - Dell Mobile Broadband utility show me message: "Nie wykryto urządzenia" - Eng. Not Detected Device. When i run a manager devices i see there one unknown device. I think that is a modem, becouse it's not on the list of network cards... When i want install a drivers to this device automatically, system show me a message that cant find a drivers to this device... I tried install drivers from dell web site a lot times but it doesnt work... Please help me, becouse it's very important for me. Thanks Mateusz(Matt/Mathew) B.
