Hello,

The reason your screens touch pad is not working is because the sensor board is no longer connected to the main panel of the phone, or the ribbon that connects the screen to the main board is faulty.

Try to open up the phone, by unscrewing it open from the back, then locating the ribbon and either try to reconnect it or replace the ribbon with a new one.

Remove your back cover, battery, sim, stylus and memory card. Now remove the cross head screw,
Lever the antenna cover off using a mobile phone opening tool.
Now remove the six screws you have access to.
Next you need to separate the battery compartment from the rest of the phone. To do so lever it away using your opening tool. There are various recesses in the back of the phone do allow you to do this.
The volume buttons are stuck to the side of the housing and need to be carefully peeled away. you can see the volume buttons after they have been unstuck from the side of the phone. You can now peel the large brown/orange ribbon away from the phone. It's held in place with double sided tape. The circuit board which the ribbon is connected to will come away with it. The on/off switch will be stuck down in the same way the volume button was and also needs to be peeled away when you remove the circuit board.
The on/off button will also come loose. Remove the screw, circled bottom left. The vibrating motor, bottom right, should be levered up so it is loose.
Lift the lower circuit board up and you'll be able to see another ribbon connector which needs to be disconnected. Again, it attaches like a plug and socket. Just lever this away from the circuit board to unplug.
To screen is held firmly in place with double sided tape and to remove it you first need to heat the screen (using a hot air gun or a hair dryer), then push your opening tool very firmly. You'll then see the screen raise slightly allowing you to slide something like a guitar plectrum or credit card behind it. Move your plastic tool all the way around the edge of the screen to release it.
You can now simply lift the screen away from the housing.
You should now have the screen removed. Reverse the whole procedure for reassembly.

Take care and good luck

How to lock a Samsung Intensity cell phone


Unlike flip phones, cell phones like the Samsung Intensity are subject to accidental keypad-pressing and dialing when they are in your pocket, purse, or even a holster. To avoid unintentionally using up voice or data minutes, you can lock your phone and temporarily disable the keypad.

There are two ways to lock a Samsung Intensity - the standard keypad lock and the security lock.

- To use the standard lock:

You can lock your phone at any time from the main screen by holding down the "0" key for about two seconds. The keypad will immediately lock, and you won't be able to use any functions or make any calls (except for calling the local emergency number). To unlock the phone, press the right option button (in the upper right corner of the keypad, next to the End button) followed by the Menu or OK button.

You can also set up Auto Key Lock, which will automatically lock your keypad after the backlight turns off. The Auto Key Lock setting can be found in the menu under Settings & Tools > Phone Settings > Auto Key Lock.

- To use the security lock:

The security lock also prevents your keypad from being used, but it requires a code to be entered in order to unlock the phone. To enable the security lock, go into the main menu and select Settings & Tools > Phone Settings > Security > Lock Phone Now. (You'll need to know your phone's security code in order to access this setting -- by default it is typically the last four digits of your phone number.)

To unlock the phone, press the right option button and then enter your phone's security code, followed by the OK button.

You can set your phone to go into security lock mode as soon as you turn it on by enabling Phone Lock Setting under the Security menu. Every time you turn your phone on, you'll need to enter the security code in order to unlock it. However, once you unlock it, it will remain unlocked until you either manually lock it or turn it off and then back on.

Emachines netbook unlock key pad


Key Pad or Touchpad? Is it that the mouse pointer is frozen and does not work? If so, look at the middle of the touchpad at the top of it and there might be a button there that lets you toggle the touchpad between locked and unlocked.

Sometimes there might be a set of keystrokes you will have to hit to lock or unlock the keypad. Most times you will have to Press and Hold the Alt, FN or Ctrl key then hit the key (most times one of the F1 thru F12 keys) that controls the keypad. The key that controls the keypad will have the icon of a finger inside or pointing at a square that represents the keypad. On one laptop recently that I worked on it was toggled by Pressing and Holding the ALT key then hit the F6 key. F6 had a finger pointing at a square area representing the touchpad.
