Acer Aspire 4830T fan replacement

In this guide I’ll be taking apart an Acer Aspire 4830T in order to access and replace the cooling fan.

In my case it started making lots of noise.

In this model there is no easy access to the fan, it’s mounted inside the case, under the keyboard.

Before you start, make sure the laptop is turned off.


Remove one screw securing the service cover on the bottom.

    Is the fan blade supposed to just pop off the motor? I’m trying to lubricate the fan in my Acer Aspire V5-571 but the blade won’t come off easily and I’m afraid to pull on it any harder. I’ve seen some say you can remove the sticker on the other side and underneath the sticker will be a rubber piece you can pop off and you can add the oil to the shaft/well that way, but there is no rubber piece to remove or any way to access the shaft this way either. Do you know how I can access the shaft or well on this particular model? My fan is making a terrible noise and until I can replace the fan entirely, I still need to be able to use my computer. Thanks!

    I have a 4830TG and the bottom case near hinge is broken to the point that the broken part sticks out every time the lid is closed. Do you know where I can possibly purchase the bottom case? I don’t mine buying generic or used ones.

    Thank you very much.

    I could remove and clean the fan of my 4830TG, but when i assembled my laptop back, it is not starting up when I power on. I can see the power light is on, fan rotating normally and USB ports also have power. But the laptop just doesn’t start up and processor light doest not light up. Can you advise how do I get my laptop started.

    It’s almost perfect procedure and most helpful guide to replace fan.
    But, I had three small differences on my machine.

    1) In step 9, there is NOT exist center screw in my machine.

    2) Before step 19, there is TWO MORE connectors at most left side and right side.
    One is in left side of the keyboard frame. It’s thin small connector.

    3) Another is in center of keyboard frame. It’s left to right thick cable.
    It is connected to USB port board at right side was fixed this on keyboard frame with screw.

    I’m very very glad at your helpful guide.
    I’ll donate a little for this.
    Thank you.

    Thank you for these useful instructions. I had no trouble taking the laptop apart. Like Toshi, above, I also had to disconnect two more connectors before I could remove the keyboard.

    But to prevent anyone else having the problem I had, the fan requires a 0000 phillips screwdriver. (all other screws are a size 0) Before I figured this out, I destroyed the heads of 2 screws. Once I had the correct size tool, the other two screws came right out. So do yourself a favor and buy a 0000 Phillips before you start.

    Now that I am in this predicament, my alternative is to remove the entire motherboard so that I can access the full fan assembly including the air channel. I’ve decided that is more than I want to tackle, so I am going to put the laptop back together and take it to a repair shop.
