How-To: Install Dell Bluetooth 365 in Precision M6500

20 Aug

So I received a brand new, ultra-fast, Dell M6500. It is everything and then some for programming and digital design needs. However, the Dell support site is rather lacking in the documentation on an aftermarket install of the Bluetooth 365 module.

Note: Do not follow instructions in the Dell M6500 Service Manual on installing it as a PAN – this is for the Wireless USB install.

Therefore, tonight, using some ingenuity and research between the M6400 and M6500, I was able to install the part.

Important! Before doing anything, discharge any static, have a clean workspace, and remove the power supply and battery.

  1. Using a tweezers, carefully remove the two screw covers on the lower right and left of the display bezel. Then remove the two screws.
  2. Using a flat, narrow, plastic device (I used a thicker zippy tie), carefully insert in the opening behind the Dell logo at the bottom of the bezel.
  3. Gently pull the bottom corners away from the display and upward. Be extra careful if you did not remove the display from the machine, as there are a few flaps at the bottom that need pulled from behind the speaker guard.
  4. Continue to gently pull outward from the display and upward until you reach the top. The top took a little wiggling and there is a magnet that messes with your mind. Eventually it will come off.
  5. I apologize for the blurring image – the area we’re looking for is at the bottom, just left off-center.
  6. Carefully pull back the black connection cable.
  7. Insert the Bluetooth 365 module first under the black plastic retaining clip.
  8. Next, keeping the black cable from step 6 out of the way, screw down the module. The hole is located behind the black connection cable.
  9. Finally, attach the cable to the module. Also, on mine, there was a pin #14 on the module and the cable, so I made certain they lined up.

That’s it! Reassemble your bezel by reversing from step 4 backwards and you’ve gotten it installed! In my Windows 7 64-bit the driver (both from the Dell site and the CD-ROM) would not install. It works, but it detects it as a Microsoft Generic Bluetooth device.

Cheers! And happy modding!

ASP.NET MVC 1 FormCollection & Checkboxes

19 Aug

While working on a project in C# 3.5 using ASP.NET MVC, I have a challenge where I cannot use a strongly-typed view. I noticed the checkbox is coded as

1
<%= Html.CheckBox("HoldFlag", Model.HoldFlag) %>

However, calling form["HoldFlag"] was behaving oddly. When the box was checked, it was returned as “true, false” but when unchecked it was “false”. So I guess for now I’m going to handle it as follows:

1
var hold = form["HoldFlag"].Contains("true");
