    These (and Dell’s) instructions don’t mention that you have to disconnect a second keyboard cable. It’s a 4 pin ZIF connector, you can see it in the picture above, already disconnected.

    There are a couple of latches on the front of the palm rest which should be released before you move on to the sides. I think one of those latches is released in the picture above. The iFixit opening tool was helpful here, and I used some of the iFixit opening picks to stop the corner latches from closing while I worked on others.

    Indeed, pull straight up using the integrated handle on the connector. It required more force than I expected, and popped off suddenly once I pulled hard enough.

    • Release the latch on the system board and then disconnect the VGA cable.

  42. Dell Vostro 3450 Hard Drive Replacement, Remove the Screw: 手順 42、 1の画像 1
    • Remove the screw that secures the VGA board.

  43. Dell Vostro 3450 Hard Drive Replacement, Remove the VGA Board: 手順 43、 1の画像 1
    • Remove the VGA board from the chassis.

    • If this is all you are doing Follow Step In Reverse if not Go to Next Step.

    If you decided to leave the display in place, you can just loosen the screw on the VGA board, and leave the board itself where it is. The board blocks access to a screw securing the system fan, but once you’ve removed the screw from the VGA board you can just push the VGA board out of the way and remove the system fan screw. Of course, this means the VGA board can move around while you’re working on the rest of the computer, but I didn’t find that was a big problem. You could temporarily reinstall the VGA board screw after you’ve removed the system fan.

  50. Dell Vostro 3450 Hard Drive Replacement, Disconnecting the System Board: 手順 50、 1の画像 1
    • Disconnect the system board from the Input/Output panel.

    This required a fair bit of force, and I wasn’t able to do it just using my fingers. I used an iFixit Opening Tool as a lever, alternating between the two ends of the connector until it released.

Stupidest HDD location EVER! You have to fully disassemble your device for the simple operation.

vytookas - 返信

Who the !&&* designs a hard drive location that requires complete disassembly of the motherboard and the laptop to replace. Horrible, horrible design.

It’s possible to skip removing the display and the WLAN card, which saves a bit of time and trouble. I think I understand why this guide and Dell’s user guide recommend removing these parts, it makes other steps a _little_ easier, but I didn’t find it was worthwhile.

BorpoIT - 返信

I’ve done this upgrade twice now, and I think the iFixit Opening Tool (along with the spudger) makes this job easier. Besides releasing latches for the palm rest and the memory door, it was very helpful to pry up the System Board from the Input/Output Panel.
