I have a laptop - Dell Adamo Onyx. It's with Win7 (64bit). Yesterday I bought a Huawei E173 HSPA usb stick with a plan. All works fine, but how can I use the sim card directly from my laptop, without the modem? I think it has 3G support (or it's GPS only?)
Given the specs I found here I would say it doesn't have a build-in 3G slot.
If unsure, check the slot where the battery is. Most laptops that are 3G enabled have a SIM slot there.
To verify, check the owners manual if there is anything about a SIM slot.
