touch screen starts on page 12
2.1 Touch Screen Calibration Prior to first use or whenever the touch screen reacts in a different place where you are touching it, start the calibration program. The procedure is as follows: 1. In Windows 7, Select "Start" - "Control Panel". 2. In Control Panel, select "Hardware and Sound". 3. In "Hardware and Sound" window, select "Tablet PC Settings". 4. In "Tablet PC Settings" dialogue, click "Calibrate" button. 2.2 User Gesture Instructions for the Touch screen The Touch screen supports single touch and rotational movements, enlargement and reduction multi-touch operations, and the user can transmit position information to the computer via touch. The touch screen uses a very low pressure movement recognition method, which only needs the finger to move lightly on the computer display screen or make a simple hand gesture to be detected by the main computer processor.
You cannot re-calibrate a screen, but you can right click on desktop then click on view then on the right menu un-tick auto arrange and align to grid then you will be able to arrange the icons however you want.
DO NOT OPERATE AS TOUCH PANTLLA Touchscreen computers and handheld devices are the newest wave of technological gadgets as of 2010. While these devices function impressively, they can malfunction just like any other technical device. Troubleshooting the touchscreen is simple and often will correct any issues.
Identify how the screen is behaving. A touchscreen will malfunction in one of two areas--sensitivity or position. If you touch the screen and the cursor is not centered on your finger, this is a position error and requires recalibration of the screen. If you touch the screen and it does not register your touch without pressing hard, this is a sensitivity error. If you touch the screen and nothing happens, this can be a sensitivity error or a malfunctioning screen. Calibrate the screen. For all main errors, calibrating the screen will correct the issue. Every device has a different method of calibration but can usually be found under a "Tools" or "Diagnostics" menu option. Reload the device. For handheld devices, remove the battery and let the device rest for no less than five minutes. For computer or computer system devices, power down the device, disconnect the touchscreen device from the computer and remove any power cords to it. Allow the device to rest for five minutes. Reattach the device or reinstall the battery and power up the device. If issues persist, reload the software for the device. For handheld devices, do a full wipe of the device and return it to factory specifications. For add-on devices to a computer or computer system, uninstall the device and reinstall the drivers. If reloading, registering or calibrating the device does not work, consult the manufacturer for possible warranty replacement options.
This has happened to me and it took me hours to figure it out. I hope yours is the same problem... Make sure you dont have your touch pad set to off. On my ASUS It is F9 on my keyboard. the key shows an icon of the touch pad with a slash (/) through it. If you do not see this on your keyboard try looking in control panel and see if there is a setting in there. Good Luck. Please let me know if this worked. Geraldine
Calibrate the touch screenThe
command buttons and fields are displayed on the screen image at
specific pixel points. To initiate a response, the touch screen
interface needs to recognize exactly where a fingertip or pen touches
the screen relative to the pixel position of the display. Each user has
a slightly different hand-eye coordination response. Calibrating the
touch screen allows the interface to compensate between where the
program is expecting a touch and where the touch actually occurs.
To calibrate the touch screen, place the tablet notebook in the desired orientation and do the following actions.
Click or tap Start > Control Panel > Tablet PC Settings
to open the Table PC Settings window.
On the General tab, select the option to display the menus in either the Right-handed
On the General tab, select the desired screen orientation
from the drop-down menu, and click or tap Calibrate
. Follow the instruction to touch the screen at the specified points.
Repeat this calibration action for all four of the screen orientations, then click or tap Apply
On the Handwriting Recognition tab, select the Use the handwriting personalization
At a later time, you can return to review the Go to Pen and Input Devices
and Go to Input Panel Settings
options to make using the touch screen to control programs and input text easier and more accurate.

The touch screen on these models do not have a calibration setting. They work or they don't. If it not working properly you can try uninstalling the drivers for the touch screen, then reboot. The machine will find the touch screen and reinstall the drivers automatically. Also check for any updated drivers at Panasonic's support site. Then check the connection for the touch screen, the touch screen has a separate connection than the screen, and it may have worked loose or have a little dirt or corrosion built up. If this doesn't work, then I'm afraid that the touch screen may be wearing out, nothing you can do for this.
