SOURCE: hcl me laptop, touchpad too sensitive, how to control?

There is an adjustment for this sensitivity go to control panel and look up the mouse if there is not icon on the tray to do any options. What your looking for in short is options in the option tick sensitivity there you can adjust it for your comfort. Locate this and your on your way. If you cannot find any touch pad information go to your manufactures web site and download the driver or software for your touch pad. It should drop to the task bar as an icon below. Or if you have the show all icons turned off turn it on it may be in there. The best way to do that is right click in the tray where the icons are and select show all icons or if you see the mouse pad icon there open it and tick options.
That is what I would do Win 7 may have loaded it but the actual configuration files may not have been downloaded, you may also wish to check out the Windows Updates and tick on all the updates you have missed you may find the software there for the mouse pad updates.
That is all I can offer maybe someone else has a better answer here. John

SOURCE: When I turn on the overhead projector it displays

Hi! This is a pretty common problem with overhead projectors. At the top of the arm that's over the unit, there should be a lens unit. The unit needs to be rotated so that one lens points down, and one lens points towards the screen. Once the lens is rotated properly, the lens unit is moved up or down in order to focus. There's usually a knob to turn to move the lens up or down.

Elmo overhead projector


Move the projector away from the wall, the picture gets bigger. Then use the focus knob at the top to get a clear picture on the wall. Then use a camera to take a picture of the wall. Then upload the picture to the place you want to transfer it to.

Overhead Projector Tip- best results!!


For best results, slant the screen forward slightly so it meets at a 90 degree angle with the projected image light beam. In not, then a keystone effect results where the projected image is taller on top or on the sides; in other words, the projected image is a parallelogram, not a square.

Overhead Projector TIp #2


Some people switch the projector on and off to shift the focus of the audience from the image back to the speaker. This also saves the lamp. This is a matter of personal presentation style.

The auto focus won't focus on images from far away, 2 feet. It only focuses at 2-3 inches


Most CMOS web-cams have a focusing ring round the lens which rotates to give you basic adjustment - after that the auto-focus should sharpen up the image

One general rule about projected image size: judge the distance between screen and farthest viewer, divide by six and use this number to figure image width.

What is an Overhead Projector?


An overhead projector is a very basic but reliable form of projector. The overhead projector displays images onto a screen or wall. It consists of a large box containing cooling fan and an extremely bright light, with a long arm extended above it. At the end of the arm is a mirror that catches and redirects the light towards the screen.
An overhead projector can be used to enlarge images onto the screen or wall for audiences to view.
