Understand.Agree, Mr_gauravin.ftp://ftp.dell.com/Manuals/all-products/esuprt_laptop/esuprt_latitude_laptop/latitude-e5400_service%20manual_en-us.pdf[ In case you cannot directly download the Service Manual in PDF file format, here is the Dell Support link,http://www.dell.com/support/Manuals/us/en/19/Product/latitude-e5400Click right on - Dell Latitude E5400 and E5500 Service Manual (1698KB) ]1) Remove ALL power. Remove the AC adapter (Charger) and Battery.2) Use an ESD wrist strap, and connect to a good ground source.(Electro Static Discharge)One example,http://www.radioshack.com/product/index.jsp?productId=2103245[I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.You can also set a large metal serving tray, (Unpainted), on the table you are working on, or use a large metal knickknack (Unpainted) ]3) Use a multi-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.SOME screws look VERY similar to other screws.Advise DO NOT mix them up.4) The wireless switch is composed of two spring metal flat strip contacts, inside a plastic housing. One flat spring steel strip is stationary. The other spring steel flat strip slides over it, to make a contact. It slides over a 'bump', or protrusion, on the stationary flat strip. The wireless button is attached to the movable strip.Due to;A) Poor designB) Low quality materialsC) Accidental bumping of wireless switch button,can make the wireless switch defective.I have been searching to find the switch itself to no avail. Perhaps you can find one, or some other expert on here has a link to one.(Suggest check 'Mom and Pop' computer stores, to see if they have one from a 'parts' laptop)IF, one cannot be procured, then suggest you use a USB wireless adapter. Use it's wireless capabilities, which will bypass the wireless module in the laptop.One example,1) http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5265581&CatId=2704IF you do find a wireless switch, in the Service Manual click on -System Board. Follow the procedures down to -Palm Rest.(Palm Rest Cover)This should gain you access to the switch.For additional questions please post in a Comment.Regards,joecoolvette
