Case
The ProBook 6540b (WD690EA) comes out strong in terms of its construction. We have to say up front that though we are not dealing with a perfectly stable construction, the whole package seems right. The heavy chassis (2.768 gram) makes no pretences with its 15.6" format and doesn't try to hide its dimensions. On the contrary, the palm rests and the working area around it comprise a surface which hangs roughly three to 6 millimeter over the edge of the notebook. Because of that, the hands especially have a very large support. The keys sit in a black, somewhat deeper lying area.
Connectivity
n terms of connection options, the ProBook 6540b displays some special features. First, the conventional attachment of the cover makes it possible to situate ports on the back. Next to the modem port (RJ11) one finds a Kensignton lock as well as an Ethernet and VGA port. Though the power socket is no doubt bulkier than necessary, it is nonetheless found on the back side. By using the side face away from the user, the optical view of the side components is less encumbered by the many cables attached.
