Panasonic Lumix Camera Review

Three days ago, after Tom adjusted some keyboard settings, he met a weird problem: the "Num" light was in green all the time, but he was unable to input any key on the screen, this qoute went on after he restarted his computer. Then he turned to me.

Though keyboard is one of the often used computer hardware devices, if it has a problem, in many cases it is due to a poor perceive or a wrong plug. After eliminating the loose connection and some hardware problems, I tried to key characters into some text editing software programs and input website addresses in the browser, both failed.

Then I brought to mind that probably the qoute was behind the wrong keyboard settings. Considering this issue happened after Tom adjusted some keyboard settings, so I tried to find it from there.

I clicked Start, selected operate Panel and then double-clicked Keyboard to check its settings, but I could not find any fault that could cause this hitch. Then I wondered either my troubleshooting formula was right or not? But I had no other good idea.

By accident, I saw the Accessibility Options in the operate Panel sheet; I knew this was designed for the disabled, and we seldom used it. Was the issue related to this item? Whatever, I tried to open it, scrutinized all the settings which were related to the keyboard and mouse there. I found that the Use Filter Keys itemwas selected by mistake, at the same time a clock appeared in the toolbar. Then I disabled this Use Filter Keys item and click Ok. Well, all things turned back general again. Finally I learned that sometimes a wrong setting in the Accessibility Options also could make your keyboard act up.
