Touch pad doesn't work


Determine What's Wrong
laptop'smag-glass_10x10.gif touch pad basically provides the functionality of a mouse for a desktop PC, typically with two buttons located just below it acting as the left and right click buttons on a desktop computer. A touch pad may be damaged by excessive use or foreign substances such as water, dirt or food items.

Hit the "Windows" button on the keyboard and then use the right-left keys (or hit 'C') to open "Control Panel." From there, again use the right-left keys to get to "Mouse" and then hit "Return."

Use the right-left keys to toggle between the tabs and open each to investigate whether any boxes had been improperly clicked by accident that cause the touch pad to become unresponsive. But if any of these steps fail to remedy the problem, then the touch pad may need to be repaired or replaced.

Repairing/Replacing TouchpadA touch pad assembly cost $100 or more and that's not including replacement installation. Hiring a specialist to replace a damaged touch pad, including parts and labor, may easily cost $200. Unless the laptop in question is worth well over $1,000 and the touch pad is deemed a necessity, such repairs are rarely worth the cost.

Attempting to replace the touch pad without certain expertise in laptop assembly may be dangerous and/or destructive. Also, getting a replacement part that's not compatible with the laptop may have catastrophic results, including irreversible damage to the laptop.So just attach a mouse to it so you can work easily.Please rate me if this solution works for you

Thanks......Have a great time.

I have a Verizon Moto Q. The buttons are not working properly. When I hit the start button, back, the arrows, or center select button, mail button and certain letters it just enters numbers or letters and...


Hi, from the question you posted, there are three likely problems to the phone. One it's either the key button pad is bad which needs to be replace, the interface of the key button pad is dirty which needs to be cleaned, or the glass I.C which controls the key button is bad which also needs to be replaced.
But i think what the problem is the cleaning of the key pad button interface because the buttons are working but they only misrepresent whatever function you try to perform on the phone.
You just need to get a mobile phone technician or an electronic repairer around you to help service and clean the board and key pad button interface, and the phone will start working fine..

Take care

Try this :) press and hold one of your push buttons on your key pad for 1-3 min and wait for the error code. if you get a F2 Error then your problem is a intermittent stuck key on your key pad and you will need to replace it to repair the problem.

What does an F1 fault indicate


MAYTAG
Range/Stove/Oven Fault Codes Failure
Code
Condition Check/Repair F1 Defective touch pad or membrane Replace touch pad or membrane (usually the touch pad)* F1 Watchdog on board Replace touch pad or clock assembly (also called the ERC) F2 Oven too hot Replace relay board (if present) or bad oven temperature sensor F3 or F4 Open or shorted oven temperature sensor Replace oven temperature sensor F5 Hardware and watchdog circuits disagree Replace clock assembly (also called the ERC) F6 Missing AC signal Check for proper voltage F7 Function key shorted or stuck button Replace touch pad or clock assembly (also called the ERC) or un-stick button F8 Analog/Digital supervisory Replace clock assembly (also called the ERC) F9 Door latch supervisory Check door lock circuit or replace clock assembly (also called the ERC) F0 Function key stuck Replace touch pad or clock assembly (also called the ERC) * Here is a simple test that you can do to determine whether the clock or the touchpad are defective when the display reads F1:

- Disconnect power to the range.
- Gain access to the back of the ERC (electronic range control, or "clock").
- Unplug the touch pad ribbon connector from the ERC. This will be a flat wire about 1 ½" to 2" wide.
- Make sure everything is clear and will not short out when power is turned back on. Replace any covers removed to gain access to the ERC.
- Turn the power back on to the range.
- Watch for the F-1 and listen for the beep.
- If you get the F-1 and beep, replace the ERC.
- If after approximately 60 Minutes you do not get the F-1 fault, replace the touch pad.

NOTE: Some models incorporate the touch pad and the clock control as one part so F1 = bad clock control.

Warning: If you do not feel comfortable doing this test or making this repair please contact a qualified appliance repair technician.

F7 fault code on the Jenn-air W30400W


The F7 error code on your oven indicates the touch pad has failed. To repair it you will need to replace the touch pad which is listed as a control panel w/keypad in the parts diagram.
If you do the repair yourself, disconnect the power to the oven. Take the 3 screws out above the door that hold the control panel on to the oven. Pull the control panel out at the bottom and lift it up, then pull out the top and drop it down so you can see the back side of the control panel, and you will see a ribbon connector going from the touchpad to the electronic oven control (ERC).
There is a latch holding the ribbon connector to the ERC, raise the latch to release and pull the ribbon out of the ERC.
Replace the part and reverse these instructions to replace the control panel.

Hope this helps .

Key Pad buttons require more force to accept the input - loosing memory!


I have the same phone with the same problem and didn't want to part with it either. The cause of the problem are skin oils that seep down the rubber keys, and through slots at the base of the molded pad, thereby interfering with electrical contact. There is a vendor on ebay that sells a tape like pad with larger contacts that solves the problem perfectly. Go to ebay and use the following search term (I know this isn't the same model number, but its apparently compatible) :

Panasonic KX-TGA230 KX-TGA270 KX-TGA230B BUTTON FIX

The price is 5.95 including shipping. The repair pad will come with an instruction sheet, or you can go to the website on the instruction sheet and download about a 40Meg video file that shows you exactly how to make the repair. My phone operates with a nice light touch now that its fixed. Good luck.
