The solution I found to these problems was to download old drivers at the sony esupport site. 1) The Intel(R) PM55 Express Chipset LPC Interface Controller - 3B03 problem was actually solved by downloading a Sony Firmware Extension Driver and installing it. 2) The Base System Device problem was actually an SDI controller driver that needed to installed. 3) The Intel(R) Centrino(R) Advanced-N + WiMAX 6250 problem was likewise installing that driver from the Sony eSupport Site for my particular model # VPCF136FM/B. All these drivers are old and the latest one was dated 2010. Nevertheless it solved all the Yellow Excalmation Icon on the Device Manager.
