Like we said before, a laptop can only be called Centrino if it has all the three (or four) components defined by Intel, according to the table presented in the previous page. If a given notebook is based on a Core Duo CPU but doesn’t have Intel PRO/Wireless 3945ABG wireless network, for example, it can’t be called Centrino.
A very common confusion is to assume that the Celeron M processor belongs to the Centrino platform. This isn’t true. Celeron M-based notebooks aren’t Centrino. For example, Toshiba’s Satellite A105-S2236 isn’t a Centrino laptop, as it is based on a Celeron M, Radeon Xpress 200M chipset and Atheros Wireless LAN (802.11b/g). On the other hand, Toshiba’s Satellite A105-S4547 is a Centrino laptop, as it has a Core Duo processor, Intel 945 Express chipset and Intel PRO/Wireless 3945ABG wireless network, which are the required components for a notebook to be called Centrino Duo.
Some sellers created the term “Celeron Centrino.” This platform does not exist, as we have already explained on our Does Celeron Centrino Exist? tutorial. This happens for the same reason explained above: even if your notebook uses a chipset and a wireless network that belong to the Centrino platform if your CPU is different from what we listed on the table presented in the previous page your notebook cannot be called Centrino.
