    Lightbulb [GUIDE] Transformer 3 Pro T303UA Disassembling Guide

    T303UA Disassembling Tutorial
    Please read this tutorial carefully one time doing nothing. The second time is the right one! :-)
    Hi all! First of all excuse-me for “my” English, I care more about electronic’s mistake than language’s one.
    I decide to write this guide because of lack of informations about disassembling this little jewel.
    Through this guide you can
    1. Fix anything broken (substitute LCD, everything about wifi and so on…);
    2. Change HD (with one more performing, bigger...);
    3. Change battery;
    4. Fix very ugly noise…And much more!;
    5. Do mods you like (add an HDD activity LED for example);
    6. Mess up your T303 if you don’t follow exactly this guide;
    7. Tell every bad you learned in your life.
    Of course most interesting cases are the not the fifth and the sixth.
    Tools you need:
    1. Hotgun or hairdryer;
    2. A deck of cards you don’t care about;
    3. A pencil and drawing line;
    4. A very good double-sided tape, 2-3 mm wide, as thin as possible (I took it on Amazon);
    5. A conductive paste (for noise fix);
    6. A lot of patience.
    Tools you DON’T need to open this laptop:
    1. Screwdriver;
    2. Clips that are frequently used to open mobile phones (yes! The blue one!);
    3. Screaming girlfriend back to you.

    First of all take some cards (maybe one won’t be enough, some cards will be damaged through this guide…) and trace a line with a distance of 4 millimeters from the short edge. You can do it in both sides, so you will be able to use both ones.
    THIS STEP IS IMPORTANT! Do not underestimate it. When you will open the BOTTOM side of the laptop if you go too much inside YOU WILL PERMANENTLY DAMAGE THE LCD SCREEN, and you will need to change it. In the other three side the risk is not much high, but please pay attention too.
    So now warm up the borders of the laptop, and we will start from the upper part of it. The piece of plastic in the upper part can be detached and it will stay attached to the LCD screen. If you want to change the LCD screen you will detach this part from the screen later.
    DO NOT PULL UP THE SCREEN IN THE WHOLE PROCEDURE. To dismantle it you need to detach some cables inside. You can pull it for few millimeters of course, but not more.
    So warm up the up left corner, and gently try to detach the grey piece of plastic from the back of the laptop until a little space will be available. At this moment put the corner of the card into it.

    Now you will turn counter-clockwise on the edge, keeping the edge warmed up by the hotgun (do not stay too near of course!), and slowly detach the edges of the screen. DO IT SLOWLY! And sometimes go back keep previous edges detached.
    PAY ATTENTION TO THE BOTTOM SIDE! THIS IS THE DANGEROUS ONE.

    20170728_172159.jpg

    If you take a look to screen pictures you understand why.

    20170729_203741.jpg

    The botton part of the screen is 5 millimeters thick. The other borders are much more wide.

    Right border.
    20170729_203755.jpg
    Up border.
    Do not worry about flat cable on the top of the screen, it is attached under the grey piece of plastic so you can’t damage it.
    EVEN IF IT SEEMS SIMPLE DO IT SLOWLY, DO NOT GO BEYOND THE LINE YOU DID ON THE CARD (ESPECIALLY AT THE BOTTOM OF THE SCREEN).
    When you will have detached every border DO NOT PULL UP THE SCREEN.
    We have to detach the flat cables (touch screen cables) at up right corner.
    So gently pull the screen and find these two cables (remember that in these pictures you are viewing the screen from the back).
    To detach them take a look to the connectors (up right corner):

    20170728_171942.jpg

    You have to lift the white plastic into both connectors, you can do it with nails (do not eat them!!!).
    After this you can detach both cables.
    The next and last step is to detach LCD screen cable. I found easier to detach cable from motherboard first. It is enough to detach every adhesive tape that keeps it attached to the case and battery, and pull down the screen. In the past picture I already reattached cable, do not care about it.
    So… You did it!
    To reassemble it it is easier of course.
    1. You have to clean every tape and glue on the edges;
    2. Put double-sided tape on the whole edge (except speakers of course!);
    3. Detach the video cable from screen and reattach to the MB first (you need to lift the copper that protects the connector, attach the cable and put more adhesive tape to lock it in place);
    4. Attach the other side of this cable to the LCD screen and lock it with the metal tape you detached in the past;
    5. Connect the two connectors about touch screen and close two clips;
    6. Remove the other side of the double-sided tape on the whole border and attach it firmly.
    7. Keep the screen in place few hours (with laundry closet for example…).

    So now let’s talk about...
    NOISE FIX
    The noise of course is emitted by the fan, when it touches the copper film around it. The copper film is quite easy to bend: when using the laptop maybe you bended it and so that’s why it makes noise.
    If you want to make it straight you can dismantle everything (as I did). After this you will need to change the conductive paste, so be sure to have it.
    I disassembled the whole piece (removing all the screws you see, even the little one). I make it straight through a hammer, I changed the conductive paste and I reassembled the part.
    I put three washers around the fan (as you can see), so that the copper film is a little bit more distant from the fan.
    I didn’t change the HDD and I didn’t any other mod, but if you take a look to the pins you can add an activity led for example.

    SO HAPPY DISSASSEMBLING!
    (but I won’t disassemble mine another time for you…:-P)

    P.S. The spare LCD part from ASUS has number 18100-12600000. I didn’t find the Service Manual of this laptop so I don’t know any other spare part code.

    Someone knows if the t303 uses the same battery as the t304? And if disassembly procedure is the same?

    I can't find the battery for t304ua, only for t303
