When it does not load , what do you see ? Is there an error message , or does it just sit there loading interminably ? What OS are you using , and do you know how to get to its command line ? <| sep |> Just to clarify neither of the standard forward or reverse clicky switches are any good ? Forward clicky means half press from off will turn it on momentarily , full click from off will turn it on permanently . Half press from off will not turn it off , only a full press and release . Reverse clicky means half press from off does nothing , full press from off and release to turn it on , half press form on turns it off momentarily . I know some LED lenser lights are just monentary or twist to turn on fully but they aren ' t generally recommended .
