Hi Cool: Couple of suggestions for you. #1: Go to Start-->My Computer, off the Start Menu, and Right-Click on My Computer. Depending on what version of windows you're running, you'll see Device Manager on the Navigation Choices on the left side of your screen. (that's in Vista; it will be different for different versions of windows as I mentioned). When you open your Device Manager, look for a Category Heading called "
IMAGING DEVICES"; click or double-click on that section and find your webcam listed. On my system, it's: "
Logitech Quickcam for Notebooks".
#2: Click on the name and brand of your Cam listed in that section (
IMAGING DEVICES); right-click on properties. If it says: "
This device is working properly", then you are good to go! You can install Video apps suck as Skype or various IM chat programs to make Video calls with your internal webcam.
***If you don't see a Webcam listed in the
IMAGING DEVICES section, or you don't see the
IMAGING DEVICES category in Device Manager at all, you probably don't have the right driver installed, or possibly no driver installed. Since it's a 2nd hand notebook, many people are UNINSTALLING their webcam software from their laptop if they don't use it, with the outbreak of the new FBI RANSOMWARE virus out in 2012. The hardware is still there inside the laptop, they just removed the software. You can go to the Fujitsu support website to download the correct drivers for your laptop webcam at:
Link Removed.
If there is no webcam driver listed, or the
IMAGING DEVICES category is not shown, go the Fujitsu website and download the correct webcam driver for your model Lifebook; they have a model selector that you can click through to get to the right model's software download page.
If there is a webcam drive listed, and it tells you "
This device is NOT working properly", then you should uninstall that driver from Device Manager and reinstall using the new webcam driver you downloaded from above Fujitsu website.
In either case, this should resolve your problem with your webcam. Pay close attention to selecting the proper drivers to download for the appropriate version of windows (xp, Vista, Win7, etc.); and especially if your laptop is using a 32bit or a 64bit processor. If you don't know which you are using, use the
SYSTEM INFORMATION command to determine this.
If none of that works, it could be the webcam optics or the internal cable is damaged or become disconnected from the Motherboard (Main computer board inside your laptop).

If this is the case, and you're familiar with how to take apart a laptop and get it working again, you might have to replace the webcam camera, or cable assembly itself. If you are not familiar with this process, I suggest you take to an A+ Certified local computer professional to do that repair and get an estimate.
I hope that proves helpful. Let me know if you have any further questions.
Good Luck!
