Changing LED Guide


DISCLAIMER: I am not liable for any damages caused by changing LED's in your system. If done incorrectly, it may cause damage to your system. Make sure to unplug computer before starting this project.

Parts Needed:
      For each LED changed:
           T1 (3mm) Blue LED. Forward Voltage 5.5V Max, Luminous Intensity:12.5 Min; 40 Typical, 60* Viewing Angle.
           100 Ohm 5% Tolerance resistor (needed if LED voltage is less than 5 volts)
      Soldering Iron, solder, heat shrink tubing (can be substituted by twisting wires together and electrical tape) or solderless
      terminals.
      Parts bought from Mouser Electronics (www.mouser.com)

Step 1: Getting to the LED's to be replaced.
Case Front:
          1. Remove Side and Top panels, if needed. Gently pull tabs (or remove screws) holding front panel in place.
          2. LED's are either screwed in with a bracket, or glued in. Remove bracket or glue to expose LED's.

Keyboard:
           1. Keyboards differ widely, but basically follow these same procedures.
           2. Unscrew bottom of keyboard.
           3. Making sure keyboard is key side down, remove bottom, plastic sheets (if there), keys (if needed). The LED's will
               be screwed in, or most likely just be sitting in there.

Step 2: Replacing LED's.
Case:
          1. Most motherboard leads have 5 volts, so there was no need for me to add a resistor. I cut the old leads off as close
               to the end of the other leads as I could.
          2. Slip a small piece of heat shrink tubing (enough to cover the connections) over the exposed wire, leaving enough
               room  to solder.
          3. Bare the wire from lead, solder the wire (heat wire, not solder) lead to the LED. Make sure you have the positive
               and negative leads correct.
          4. Slide heat shrink tubing over the connection, and heat (with heat gun, lighter, etc.) until tubing is tight against the
               connection.
          5. Turn on the power and make sure it works.
