I would first check and verify that the electrical outlet or power strip that they are plugged into is working. If a plug gets in a bind it could have blown a fuse on the power strip or the power strip might have a reset switch on it. Or the power strip might have failed. If you have a uninteruptable powersupply that you plug everything into you will need to confirm that it is working as well, test it and look for reset buttons or a fuse holder on it. Your electrical cords could have been pulled out from the wall outlet itself while cleaning sometimes even wall outlets if put in a bind from pressure will blow a fuse or the cord might pull out just enough that it is not making a good connection.
You might get a lamp with a bulb that you know works and plug it into the same electrical receptical that you have the dell computers power cord plugged into and then test the monitor power source the same way.
If the outlets or power strip are getting power and that is confirmed by testing them, and then you plug in the Monitor and Dell power cords into the sources that you have confirmed are getting power, and they do not come on we have a different problem.
If the monitor is hooked up wrong to the computer or not even hooked to the computer the light should come on on the front of the monitor incicating that it is getting power. If you plug it into a confirmed working electrical outlet the light should come on on the power button of the monitor. If it does not come on then somehting might hve possibly damaged all of the epuipment that was plugged in like a power spike on the electrical lines going into your home, this would be very rare but not impossible.
I am sorry for all of the senerios but you were not really clear on what you were using as power sources going to the equipment and I wanted to try and cover the most common possibilities in one email. Please let me know if this helps

Why does my monitor start as white when I turn it on? THe mouse pad does not work as well.


Monitor cable disconnected internally?

follow http://www.insidemylaptop.com/replace-screen-on-dell-latitude-e5420-laptop/
and disconnect, clean and reconnect ALL monitor related cables. (You may need a new screen if that fails)

You may check your laptop by connecting an external monitor first.

KEYBOARD WILL NOT WORK ON DEMENSION 3000 UNABLE TO TYPE ANYTHING


Keyboard might be bad or you might have a virus that has hijacked the keyboard.

Make sure the keyboard is plugged into the computer good. Then reboot the computer into Safe Mode and see if the Keyboard works.
Turn off the computer, then hit the power button to turn itback on and immediately start hitting the F8 key repeatedly until you see SAFEMODE. Take the Safe Mode option and let it boot up. Safe Mode will lookdifferent to you, the screen will be darker and the icons bigger, this isnormal.

Built in mouse has not worked properly from day 1. Now my external mouse won't work either. I tried a different external moue, but it doesn't work either.


Unplug everything except the power cord, including the following:

Speakers
Printers
Scanners
USB devices
Personal Digital Assistants (PDAs)
USB flash drive or other external storage devices
External Monitor
External Keyboard
External Mouse
If your computer is attached to a docking station, undock it.



Make sure the touchpad or your finger has no dirt, grease, liquids or food on it (the touchpad has to make a good contact with your finger to work correctly).


Turn the computer back on and retest the touchpad.

When the touchpad still does not work correctly proceed to step 5.

When the touchpad does work correctly, attach one external device at a time and test the touchpad to see which one may have caused the issue.



Make sure the latest driver for the touchpad is installed (you may need to use a external USB or Bluetooth mouse), for more information refer to:

Dead pc


try to remove all external device connected to your computer. just leave the keyboad, mouse and monitor connected.
restart computer.
if still a blank screen
remove everything connected to your computer (mouse kyeboard and monitor) restart if nothing happens
open your computer and remove all devices (hard drive, optical drives, memory... restart,,, you should be hearing beeping sounds indicating motherboard is looking for memory. try putting back 1 memory at a time and checking all mem slot. to identify if one of the memory could be causing the blank screen. if both memory will not work try to use known good working memory. if you dont get to hear the beeping sound using a known good working memory. your memory is the problem.
give me more info

Mouse touchpad, keyboard, and usb drives will not work


One thing you can try (for the touchpad)

Acer have got a function key to turn it on and iff (i thought mine was broken for a year). Hold the function key, which is located bottom left of keyboard, and then press F7. It should be F7 anyway.

Hope that helps for your touchpad
