Question about Dell Latitude C400 Notebook

1 Answer

Need to take a C400 apart

I have a C400 with a wobbly USB socket. I'd like to take it apart and secure this socket but can't get the case apart.


I've taken all the screws out of the bottom, including the ones hidden by the battery but it still won't come apart.


Is there a sketch anywhere on the internet that shows just what is holding it together?


Thanks in advance for any advice.

    I have the same problem which affects the connectivíty of the USB. Does the USB connector need to be re-soldered to the pcb for reliable connection?

    Did anyone find out more about this USB problem? My brother-in-law needs a fix for this too but we'd prefer not to take the laptop apart without knowing someone else's experience first.

    The Dell Latitude C400 laptop contains a small "CMOS" battery that is located deep inside the machine. People commonly call this the "backup battery" or "BIOS" battery. It keeps the system information and the correct date and time while the laptop is powered off. One indication of a dying or dead CMOS battery is that your system tray's clock consistently displays the incorrect time. Anyone can access the CMOS battery, but it entails disassembling the laptop.
    Difficulty: Challenging
    Things You'll Need:
    Phillips head screwdriver
    Flat head screwdriver
    Turn off your Dell Latitude C400 laptop and unplug any connections to it. Flip it upside down to access the back panel.
    Slide the battery switch to the side and pull off the external battery pack.
    Remove all the screws you can see on the back of the laptop.
    Pull off the panel on the lower right hand side of the laptop. Slide out the hard drive and remove it.
    Flip over the laptop and open the lid. Push the lid all the way back so that it touches the table.
    Press the "F5" and "F4" keys at the same time to force the keyboard to pop up.
    Slide a flat head screwdriver underneath the left side of the keyboard to slightly pull it up.
    Remove the screws at the top of the keyboard.
    Unhook the single cable that connects the keyboard to the motherboard. Pull out the keyboard.
    Remove two screws that are located at the upper left hand corner. Unhook the cable next to them and remove the display screen.
    Remove the screws located near the edges of the palm rest and remove the palm rest.
    Disconnect the cable that holds down the CMOS battery, which is located in the lower right hand corner underneath the fan. Connect a new CMOS battery into the cable if you need to replace it.
    Reassemble the laptop following these steps in reverse.

My washer sounds like a freight train, I have been finding pieces of plastic in with the closth

I dont know whether you have secured the dryer to stop it from moving if it shakes about you need to secure it and make sure it is level(eg the floor is level or the dryer is level and all the leg screws are down and even so it doesn't wobble about.

The more the dryer wobbles about the drum inside will wobble inside the casing and it will break the things that hold the drum in place ,sound like that has already happened.but secure it in place and see what happens.

I cant format my C400 with a pen drive

If you're tryng to format the HDD on a Dell latitude C400 (or install an OS), this thing will not boot to any USB devices (flash drives, pen drives, external USB cd-rom drives, etc.) - just ain't gonna happen since the BIOS doesn't support such boot devices. The only thing it'll boot to is (1) docking station, and (2) a Media Bay optical drive.

Need high speed usb driver

Unfortunately, being that you are using USB 1.1 ports, the high speed 2.0 devices cannot be used. They look the same, but are different hardwares. Even if you hook up a USB 2.0 hub to the USB 1.1 port, you are still stuck with USB 1.1 speed.

Sorry to break the bad news. Let me know if there are any more questions regarding this issue.

The usb of my dell latitude c400 notebook is malfunctioning

Unfortunately, I have seen this many times. One of the major problems with the C400 model was the USB port failing. I have had many of them replaced under warranty, and I have repaired some. The USB port breaks loose from the mother board and stops working. It is possible to SOMETIMES disassemble the laptop enough to get to the port and re-solder the USB port connections. But is is a slow process for experienced people. And it does not work all of the time. i know that this is not the answer that you wanted.

Good luck with it.

No connection HP photosmart 8050 printer

Hi from France,
I am now repairing my printer (Photosmart 8050) with the same problem. It is due to the welds of the USB pins of the socket on the printed board. It is thus necessary to open the printer by means of a screwdriver Torx. You need a little soldering iron in order to weld the four pins of the USB socket, and then I recommand to strengthen the connections and the socket by means of hot glue.

best regards,
