I have a Dell Demension 5100, and the power button got stuck. By stuck, I mean that the power button is pushed in, but not released. It's stuck as if you pressed the power button, but did not release...


if your PC have restart button then open your PC and check the power cable slots and change them into a reset mode removing reset cable to reset slots and attach to power slot. Then you can power your pC with reset button. If you can open front case then you can outside the button .

check the bezel/power button
try to open the tower but you have to make sure that its unplugged/ after unplugging the power cable press the power button for about 5 secs to drain the flea power then check the power button maybe its broken or the cable connected to the power button to the main board is damaged or loose.

Unable to remove cover from dell dimension 8400 desktop pc


This Dell Support, and the Service Manual for the Dimension 8400,

http://support.dell.com/support/edocs/systems/dim8400/SM/index.htm

In the Service Manual main menu, left-click on - Opening the Computer Cover

1) Computer off, and unplugged from power. (Always unplug the power cable from the surge protector. Then if the power cable needs to be removed from the computer, do so)

2) Remove all cables to the computer

3) Lay the computer on it's Right side.
(As you face the computer, your right side is the computers Right)

4) There is a Release button on the Top of the computer case, and a Release Button on the Bottom of the computer case.
These are located at the Rear of the computer.

The preferred method of opening the computer case, is to press one release button in at a time, and slightly lift up on the side of the computer case, where that release button is located near.

Then go to the other side of the computer case, press this release button in, and lift up on the computer case.

The computer case opens like a clamshell. The computer case is hinged at the front.

Example:
Computer laying on it's right side. Press the Top release button in, and lift up on the computer cover located near the Top.

Now press the release button on the Bottom. Lift the computer case up.

The computer case opens from the back, towards the front, like opening a car hood.

Hi I cannot get my d.v.d drive to open and close. What do I do?


  1. If the keyboard has a CD/DVD Eject key, press it. The Eject key is usually placed by the volume knob and is marked by a triangle pointing up with a line underneath.
  2. Double-click My Computer .
  3. Right-click the icon for the CD, CDRW, or DVD drive that is stuck, and then click Eject.
  4. If the CD or DVD drive door button is a long clear plastic bar on the front of the PC, press firmly on the right side of bar. Some models have a button on the front panel of the PC to the right of the hinged door. Press the button to eject the drive.
  5. If the drive door button is part of the PC case and is covering the actual drive door, open the door that is part of the PC case and press the Eject button on the faceplate of the drive.
  6. Restart the PC and press the Eject button on the front of the drive when the first screen appears (before Windows launches). If the drive door opens this way but does not open in Windows, another software program is taking control of the CD driver. Try shutting down or configuring any software programs that create discs or monitor the CD or DVD drive.
  7. If the door still does not open, do the following:
    1. Close all programs and shut down the PC.
    2. Unplug the power cord from the power outlet.
    3. Look for the small hole on the faceplate of the CD or DVD drive. This is the manual release. The location of the manual release hole will vary

  1. Straighten the paperclip and insert it into the manual release hole until resistance is felt.
  2. Once the resistance is felt, keep pushing the paper clip until the drawer opens a little.
  3. Remove the paper clip and gently pull out the drawer until the disc is accessible.
  4. Remove the CD and turn on the PC.
If the tray still does not open, do the following steps to check the power cable for the drive. Work on a hard flat surface over a non-carpeted floor:

  1. Turn off the PC.
  2. Unplug all power cords from the back of the PC.
  3. Press and release the Power button on the front of the computer.
  4. Remove the side panel.
e0ef68c.gif
  1. Unplug the power cable and wait five seconds.
  2. Find a different power cable that is not being used, plug the different power cable into the back of the drive, making sure that it fits firmly into the socket. If a different power cable is not available, replug the original power cable into the back of the drive, making sure that it fits firmly into the socket.
  3. Replace the side panel and plug in the power cord.

  1. Turn on the PC and press the eject button on the front of the drive.
If the optical drive does not have the manual eject feature and the CD tray will not open by using the steps in this document or if a disc has shattered inside the drive, the CD, CDRW, DVD drive may need to be replaced.

Thanks
