Computers do not communicate directly with satellites they connect with ground towers/stations and THOSE communicate with satellites. The laptop talks to the satellites through a proxy.
Obviously any ground stations are inactive due to being without power for almost two years.
Even if the computer could/can connect with satellites, satellites requite occasional data and instructions from ground sites in order to ensure that the satellites are staying in the proper position, not to mention staying on the same time as us as their altitude starts to make gravitational time-dilation something of a factor.
Without being maintained from the ground the satellite network would quickly become out of alignment with ground stations and be of little use.
The group's been in this situation for almost two years now and has encountered groups from other areas, not to mention what they learned from Jenner at the CDC. It's probably pretty clear to them that the world is over so using a computer to try and to communicate with a computer network hundreds of miles away would be pointless.
