Hi DELL-Saharsh K
Windows 8.1 preview x64 UK.
I removed the 1TB HDD the 15R 5537 came with and replaced it with the Samsung SSD 840 Pro.
The 'Flight mode' switch seems to be working fine. It does switch off the external wirelless I am using now.
I did notice that the wireless light has never been on, no matter whether the Flight mode is off or on.
The remaining 2 items not enabled in the Device Manager are:
Network Controller: PCI\VEN_168C&DEV_0036&SUBSYS_020C1028&REV_01
PCIe Simple Communications Controller: PCI\VEN_8086&DEV_9C3A&SUBSYS_05E91028&REV_04
Under Network Adapters:
Realtek PCIe FE Family Controller (PCI\VEN_10EC&DEV_8136&SUBSYS_05E91028&REV_07) is there and working finne (driver: 8.10.1226.2012)
