Acer Aspire V3-551-8469 disassembly



In the following guide I will disassemble an Acer Aspire V3-551-8469 laptop in order to remove the cooling fan.

The fan is mounted deep inside the case, under the motherboard.

STEP 1.

Turn off the laptop.

Unlock and remove the battery.

STEP 2.

Remove two screws securing the bottom cover.

I’m using a guitar pick to separate the palm rest from the bottom case.

You can use a piece of plastic.

Here’s how to unlock all three connectors.

Slowly slide the cable retainer (dark brown piece in my picture) away from the connector base about 2 millimeters (two green arrows). This will unlock the connector.

Now you can replace the fan if necessary or apply new thermal grease on the processor.

There are a few chips covered by thermal pads. Leave thermal pads in place.

  1. Hopefully the next person reads this comment before servicing. The 4 screws on the bottom of the laptop on the top 2 corners on Step 5 SHOULD NOT be removed. Removing them and forcing the display to open will rip through the plastic casing. The screen is still being held down by the bezel with more screws. Any of the other screws are fine to remove except the 4 mentioned. Good luck.

    @ Nestor,

    The 4 screws on the bottom of the laptop on the top 2 corners on Step 5 SHOULD NOT be removed. Removing them and forcing the display to open will rip through the plastic casing.

    I don’t think this is correct. Without removing 4 screws shown in the step 5 you will not be able to remove the top cover.
    The display hinges secured by 4 screws and you can see them in the step 13.

    If you remove all screws shown in the step 5, the display SHOULD NOT fall.

  3. After I disassemble and reassemble my Acer Aspire V3-551 I turn it on and the power light comes on and that’s it know else happen. Where did I went wrong. I went back and remove the CMOS battery and no luck… Please can someone help me.

    @ Chris,
    Check RAM modules. Maybe one of the modules not seated correctly. Try reconnecting them.

  5. I just realized that my battery needed to charge.. Its up on running..

  6. After it finish charge and I turn it on it is now saying boot failed HDD, bootnfailed DVDRAM Drive… I tried a windows 7 CD to see if it will boot from it and it didn’t boot failed

  7. I’m so glad I found this site, otherwise I would have given up already! I have this model and it will not boot. On attempt i hear a clicking sound 3 times where the fan is located i think. Then an error stating that it can’t find the MBR. I assume it is the fan but please help if you know of something else. Also,can the fan be ordered as a separate part or is it integrated into the motherboard? If not integrated, can you provide the part number?

    @ LM,
    Could be hard drive failure. Remove the hard drive and try turning on the laptop. Do you still here clicking sounds?

  9. Hi guys, just wondering if the cpu can be replaced in this laptop? I want to go from the 4600M to the 5750M. both have the same specs except for the clock speed (5750 being ~200 MHz higher) and the graphics “chip” as one would call it (8650G on the 5750. Also, is this a good choice? I just want maximum graphics performance from this because i do CAD work on it and its falling below expectations now, although when i got it, it was amazing. for the money. :/

    @ Steve,

    just wondering if the cpu can be replaced in this laptop?

    Technically it’s possible to replace the CPU. It’s not soldered to the motherboard. Simply unlock the socket, remove the old CPU, installed a new one and lock it.

    I want to go from the 4600M to the 5750M. both have the same specs except for the clock speed (5750 being ~200 MHz higher)

    I’m not sure 100% but if both have same specs I think you can do that.
