    HOW TO REPLACE A DAMAGED ADAPTOR ON A LAPSAFE MINI MENTOR TROLLEY

    Disclaimer: While due care has been used in preparing this tutorial, I take no responsibility for any harm or loss arising from use of or reliance upon the information provided. You should not rely nor act upon any of the information contained on this page without obtaining professional advice

    If you are unsure of what you are doing or any of the included information, it is your responsibility to obtain advice or guidance from a certified electrical contractor or the original manufacturer of the goods.


    So you need to replace a damaged adaptor on your Lapsafe Mini Mentor? This step‐by‐step guide will show you what’s involved.

    It has happened to us all, finding out that one of the leads has been shut in the Lapsafe Trolley door and has been damaged - leaving the trolley unusable due to the risk of electric shock. Depending on the outstanding warranty on the unit it could be repaired onsite, or returned to the manufacturer for the repair. If your laptops are in constant demand, then being unable to use them while the trolley is away for repair is not an option.

    Thankfully the adaptors are simply a plug in module, and can be purchased individually. I suggest purchasing some spare modules with any new trolley so you have some on hand when the need arises. Thanks to the well thought-out design and build of Lapsafe equipment; as long as you’re handy with a screwdriver and you are confident in replacing components on a desktop or laptop computer, you should be able to carry out this repair yourself.

    Safety warning: As with any electrical device, you need be very careful when opening up your Lapsafe trolley. You are dealing with electricity which can kill. Please make sure you disconnect your trolley from the mains electricity supply before you start and as an added precaution, stop and check that the electrical socket where the trolley had been plugged in is empty. Please make ABSOLUTELY sure that your trolley is NOT plugged into the mains electricity.

    TOOLS YOU WILL NEED

    • Trolley keys.
    • Long Allen key.
    • Small spanner or long nose pliers.
    • New adaptor.



    BEFORE YOU START

    Make sure you have the correct replacement adaptor.

    Make sure the trolley has been disconnected from the mains.


    This is the adaptor that will be replaced in this tutorial.


    As is always the case it is on the bottom shelf. At least this gives us the opportunity to go through the process of removing all the shelves.

    1. Remove laptops.

    2. Open rear compartment using the keys supplied with your trolley.


    3. Unplug the power cables for the shelf modules.


    4. Remove the 4 Allen key bolts from the first shelf module only.


    5. With the Allen key bolts removed carefully remove the shelf module by gently sliding it out of the trolley. Take care as most of the weight is to the rear of the shelf modules.

    Please note if you have a DTM option you will have to disconnect the network cable for the shelf modules switch.


    6. Repeat step 5 for the remaining shelf modules. Please make sure you remove the second shelf before removing the third.


    7. You can now gain access to the shelf module that you require.

    8. Place the shelf unit on a flat surface so that you can see the monitor board. There are 2 nuts holding the monitor board bracket to the shelf module and 3 nuts holding the monitor board to its bracket. You will need to remove all the nuts in order to replace the adaptor module.


    9. Using either your small spanner or pliers, remove the 3 nuts holding the monitor board to the bracket.


    10. Using either your small spanner or pliers, remove the 2 nuts holding the monitor board bracket to the shelf module.


    11. Gently move the monitor board bracket away from the shelf module.


    12. Gently separate the monitor board away from its bracket just enough to gain access to the adaptors connector.


    13. Remove the damaged cable.


    14. Feed the new adaptor cable through the hole in the front of the shelf module.


    15. Connect the new adaptor to the monitor board.


    16. Slide new adaptor into the monitor board bracket.


    17. Gently align the monitor board back onto its bracket.

    18. Using either your small spanner or pliers replace the 2 nuts holding the monitor board bracket to the shelf module. Make sure you align the bracket using the correct holes.

    19. Using either your small spanner or pliers replace the 3 nuts holding the monitor board to the bracket.


    20. Working from the bottom up gently slid the bottom shelf module back into the trolley taking care not to trap any cables.

    Please note if you have a DTM option you will have to connect the network cable for the shelf modules switch.

    With the shelf module in place replace the 4 Allen key bolts. Do not fully tighten at this stage.


    21. Repeat step 20 for the remaining 2 shelf modules.


    22. When all the shelf modules are aligned tighten all the Allen key bolts.

    23. Reattach the power cables for the shelf modules.

    24. Lock the rear compartment.

    25. You have now fixed your trolley.

    Yes they are rather bullet proof. Hasn't missed a beat in 3 years of use, well apart from the trapped lead

    They have to be the way the kids abuse them! I'm kinda wishing we bought these ones now, we've got Lapcabby ones instead, the built in charger idea in your own is definitely a god-send. Excellent write-up, by the way.

    H Sysman,

    Great article you have here. I was wondering though, where did you purchase your replacement adapters from? i cant seem to find any on the net. If you had time to let me know that would be fantastic.

    James.

    IIRC I ordered them direct from Lapsafe. About £5.00 each I think.
