Manufacturers want you to try out the test version of their products before they hit the market. This is to reduce and debug any potential glitches in both the software and hardware, but a free test laptop is kept by the tester, becoming their property. This means that you can do anything to the laptop, and the manufacturers want you to do anything. They want you to test the limits of their machine with your software, and work the internal hardware to create something totally new. It is important to note that once you're a part of the testing process, you should practice good testing skills and provide feedback. Even the smallest of details can greatly help manufacturers develop better computers for the market. Since they've given you a free test laptop, the least you can do is give them tester's feedback. It's a symbiotic relationship between the manufacturer and the beta testing community, and it should be honored. Today, we're going to teach you how to modify an ordinary laptop and upgrade it to a touchscreen laptop. This is a simpler simple task, but it also requires some basic tools and knowledge:

1.) Soldering Gun – This is an absolutely essential tool when you're working with any type of internal computer parts.
2.) DuoSense touchscreen layer or similar product.
3.) LCD screen laptop.
4.) Multi-tool screwdriver.
5.) Patience.
6.) Open source touchscreen software (can be found on Sourceforge or by request from laptop manufacturer)
7.) Utility / Pocket knife
8.) Superglue

Step by step, here's how to turn your laptop into a multi-touch screen system:
1.) Use your knife to break the first layer of the screen by gently sliding it along the edge of the screen. Remove the manufacturer's glue seal by gently digging the knife behind the screen.
2.) Remove the film from the first layer of the LCD screen. You should now see an LCD screen monitor and the back frame of the laptop.
3.) Dig the knife gently through the foam or glue that holds the LCD screen to the back frame. Loosen up the wires by gently nudging the knife through the seal.
4.) Clip each wire with your utility knife.
5.) Lay the DuoSense film over the top of the LCD screen. Solder wires to the inputs.
6.) Superglue the edges of the frame to the LCD screen. Make sure not to use too much, just enough to lock the frame back in place.
7.) Unscrew the base of the screen and re-sold the DuoSense wires into the monitor.
8.) Screw the frame back together.
9.) Install necessary drivers, which can be purchased from open source touchscreen websites.

Now, you have a multi-touchscreen free test laptop . Make sure to polish the screen and remove any gluey debris after you are done installing the screen. It is important to keep any temporary pieces of plastic or glue out of the computer, as loose pieces could fall out and jam the fans, potentially melting your chipset and irreversibly damaging your computer. WARNING: Always wear safety goggles when working with a soldering gun.
