How do I replace the AC adapter port on an original LabQuest?

The preferred way to replace the AC adapter port on an original LabQuest is to replace the UAP (USB, Audio, Power) circuit board in the unit. Unfortunately, we no longer have replacement boards available as some component parts that make up the board are no longer available.

It is possible to replace just the power jack, but that can be tricky, and if not done right, additional damage can be done to the board. Because of this, we no longer make this repair ourselves. If this is something you want to try, it should only be done by someone that is pretty good at soldering electronic components. Below is information on getting the component you need for the repair.

      Manufacturer: Mouser Electronics
      Part Number: KLDX-SMT-0201L-BTR

If replacing the adapter port is not for you, here are a couple of options that might allow you to continue using your original LabQuest. These options assume that your LabQuest works normally, except for the power port, and that you will be required to use the LabQuest on battery power only.

1. Charge the unit using a LabQuest Charge Station, order code LQ2-CRG, $129. Note: This charging station does not include the inserts necessary to work the the original LabQuest.
     You can get the inserts for free, but you will want to request them when purchasing the charging station.
     LabQuest Charge Station Insert (Set of 4), order code LQ-CRG-INST, $8

2. Use a different LabQuest unit to charge the battery, switching batteries between units as needed. See TIL 2189: How do I remove or replace a LabQuest battery?
     NOTE: This is certainly not ideal and we only suggest this as a last resort as it is easy to damage the battery connector on a LabQuest, which is also something not easily repaired.
