I have a working IBM computers with a wireless keyboard, configured a wireless mouse and a wireless transmitter, and all of them with me very well. But recently my mouse pointer does not respond after I changed the battery. First, I do not know what is going on with him, but I am sure that my keyboard and mouse have no mechanical problems. Then I'll try to fix it.

Above all, I think I should control the installation of the battery. It was installed properly and theLED on this optical mouse is available in red, I can confirm that this device is operating normally. However, not why my mouse is still no answer?

One of the most common problems in Samsung 153v LCD Monitor was display dim. If you were closer to the screen and start to watch the display in dark environments, you can see the display, but it was very dark. When you press the button on the front, the On Screen Display (OSD) had appeared, and this proves that the logic board, driver-board and LCD panel is working and the problem is the inverter board. The function of the inverter board is creating a wave of ac voltageWhere the lamps at the top and bottom of the LCD monitor was. When the inverter board has problems, it would not light the lamps and what it can display only a faint to be seen.
