Screen is dark but image is present

I opened my laptop in order to fix a usb port that was functioning. Everything was going well until the end of the reassembling end. I was screwing a screw that holds the lcd connection to the motherboard. The screw slipped and touch two chips that were about 1/2 an inch away. A spark jumped out. At this point I knew I was going to have a problem. I finished putting it together. Pushed the power button, then i noticed that a didn't have backlight. Could it be the video card that I damaged or the backlight? Any assistance very appreciated.

Hi, You are VERY LUCKY, forget the laptop you could have fried yourself. My guess is you blew the inverter board. The board amplifies the current coming in to power the LCD screen. Why did you have power running while you was working?

Lenovo Touch pad Stopped working

If you're positive you didn't unplug or rip anything while installing new USB ports, trying checking/updating or rolling back the drivers for the touch pad. Installing new USB ports could have mis-configured something and disabled or modified your drivers for the touch pad.

I have Samsung R590 Laptop which i bought December last year... Before the USB ports used to work properly and display wt ever data is present in the usb ... but now it reads the data but all appear as...

Microsoft Knowledge Base
Article 971029
describes an update to Autorun that restricts AutoPlay
functionality to CD and DVD media. This update is intended to stop AutoPlay
functionality from working on USB drives, external hard drives, or network
shares. This update is available for supported editions of Windows XP, Windows
Server 2003, Windows Vista, and Windows Server 2008.

Removable USB/thumb drives use the Autorun feature to load files when the drives are plugged into the USB port. Malware exploits the Autorun feature to spread from thumb drive to PC. Disable the autorun feature to prevent malware from spreading.

The preceding describes what has likely happened to your USB ports due to Windows update disabling the autorun feature for USB thumbdrives. The thumbdrive may no longer present its data properly unless you manually invoke the autorun in its root.

How do I connect the laptop to the projector using Power Point.

Connect the data projector to the video port on the laptop. Then power up the data projector and then the laptop, the video data will automatically be diverted to the data projector.
If you want to see the Windows image on your laptop screen as well you need to press and hold down the FN key plus one of the function keys on you laptop which has a screen symbol. Pressing this key will toggle between the laptop screen, data projector or both laptop screen plus data projector.
You can open Power Point and select your presentation as you would normally.

Newly bought webcam is giving dark image .product spec.is E-8MPIR

Normal 0 Disconnect the Camera from the USB port and reinstall the CD or Downloaded software program. When the program asks you to connect the camera to the USB port, do so and it should work. Then to use it on the Web, do this.
Web Camera’s have to be setup on the program they are to be used with. Just installing the camera on your computer does not set it up to broadcast on messengers or Skype.
Each program has Options that have to be setup in order for the Audio and Video to function properly.
A. Skype Setup:
After downloading and installing Skype (http://www.skype.com/intl/en-gb/download/skype/windows/beta/downloading/ ) set it up as follows:
  1. Go to Tools, then Options, and click on Audio Settings and set the Microphone and Speakers to the computer Audio Card.
  2. Then click on the Video Settings.
  3. The camera if Installed Properly will come up and show a video picture.
  4. Then, on the bottom of the page click on Save.
The camera and audio should function properly. Your friends and Family will now be able to see and her to you.

B. Yahoo Setup:
After downloading and installing Yahoo Messenger (http://www.soft32.com/download_30.html ) set it up as follows:
  1. Go to Messenger at the top left and click on it.
  2. Next go down to Preferences and click on it.
  3. Next Calling and Devices on the right and set the Microphone and Speakers to the computer Audio Card.
  4. Next go to the Test Audio section and (in blue writing) click on “Open the call setup assistant” and follow the instructions on the left window.
Hope this helps. Bud

Complete dark screen on quick cam

Try unplugging the USB cable and replugging it while the computer is on. I had the same problem you describe and also did a soft reboot of the computer which did not fix it. Cycling the power of the camera by unplugging it and plugging it back in fixed the picture.

USB not working on HP NX7010

Could be another issue dragging the data circuit down for USB functions. If you plug a USB device in with an LED on it does the light come in? If you have electronics or basic electrical knowledge also look to be sure the 5V supply is present. Ive seen Integrated modem/audio chips kill USB function as well as embedded controller chipset issues. Everything shows working in device manager? Try not mapping thru Modem and see if USB returns.. Yell back..
