*Tip* Intel 4965agn and Windows 7 Installation Problems

Trying to install the Intel 4965agn wireless card on your laptop running Windows 7 but Windows fails to show any wireless network after the install?

Backup your settings and preferences in ZoneAlarm and AVG Anti Virus, uninstall both of these products, re-install the wireless card, restart your computer, and reinstall ZoneAlarm and AVG. You should  be good to go. Not sure why but a few people have told me that ZoneAlarm and AVG are causing a problem with Windows 7 not able to view wireless networks if they install the Intel 4965agn wireless card after installing those two pieces of software. I’ve experienced this first hand on two Inspiron 1525 laptops. Uninstalling and re-installing these two products seem to help most people. For me it was just uninstalling/re-installing ZoneAlarm that solved my problem.

Remap the Dell MR425 IR Remote to Winamp Commands

Update: To remove the error messages simply remove the duplicate commands in Winamp. For example, if there are two “Previous Track” commands remove one of them.

I recently purchased a Dell Infrared Remote (Dell Part Number: MR425) for my Inspiron 1525. I knew my Inspiron had an infrared receiver and by default only a few keys worked in Windows 7 such as volume up/down and mute.

Using Winamp I was able to remap the keys on the remote to basic functions and add a custom command to show/hide (or minimize/restore) the Winamp window.

First, you’ll need Winamp and the IR Remote. Once you have the remote and Winamp, open the Winamp program.

Next, go to “Options” and then select “Preferences” or press CTRL+P.

A new window will appear. Select “Global Hotkeys” and then check the “Enabled” checkbox. This will “un gray” the unavailable hotkeys.

To begin remapping keys, I selected the “Playback:Rewind” hotkey. The default Winamp action will appear in the “Hotkey” area at the bottom of the window.

Once the default Winamp text appears in the “Hotkey” box at the bottom of the screen, click once in the Hotkey box. Usually your cursor will blink in the box waiting for you to type in a new command. Point the infrared remote at your laptop (FYI: the sensor is next to the audio jacks in the front of the laptop). Once your remote is aimed at the laptop, press the “rewind” button on the remote (or any key that you wish to act as the rewind function). The action will change text. Mine changed from the default CTRL+ALT+LEFT to CRTL+ALT+B. Once the action has been changed, select the “Set” key to save your changes.

Continue to change the default actions to the new actions on the remote. When you’ve completed your changes, close the window. You may receive an error message.

Although I received an error message, the actions I changed continued to work when I pressed the key on the remote. In other words, “Stop” continued to “Stop”, “Playback: Previous in playlist” cycled backwards, and “Playback: Next in playlist” cycled forwards.

You might also notice a red “X” next to the remapped keys. Once again, I still have the appropriate remapped functions.

You can even add a new action with the remaining keys. For example, I added the ability to minimize and restore the Winamp window. Select the down arrow in the “Action” drop-down menu.

In my case I selected “UI:Bring to front/hide Winamp” (UI = User Interface).

Once the appropriate action has been selected, click in the “Hotkey” area and press the appropriate key on the remote and select “Add” to add the function to the list of hotkeys. I used the “checkbox” key on the remote.

If all goes well you should have successfully mapped your Dell infrared remote to Winamp.

BU-353 GPS Receiver and Inspiron 1525

Before I go into my recent laptop upgrade, here are reviews of the BU-353 GPS receiver and Microsoft Streets and Trips, both of which I’m using on this laptop mod:

Now I’m going to jump right in: I permanately mounted my BU-353 GPS receiver to my Inspiron 1525 by drilling a small 1/4″ hole into the rear of the laptop near the CPU exhaust port. I soldered the GPS receiver onto a (previoulsy broken) USB port and finished it off by sealing the port with GE Silicone II Kitchen and Bath clear silicone. The crappy pictures from my Blackberry don’t do the mod justice, but you get the idea.

I’m using Microsoft Streets and Trips 2010 for GPS tracking. This GPS works great outdoors and very well indoors. Satellite acquisition time is within 3 seconds from a cold boot. Laptop battery life has not been affected when in standby mode or while running on battery while not utilizing the GPS receiver. I plan to add an on/off slider switch at some point in the future.

One final note. I had problems with the receiver being detected in streets and trips. I had to change the port speed to 4800 from the default 9600.
