Q: I have a dell desktop. And an hp ps#92;2 keyboard connected to it via a gigaware usb adapter. Yesterday it randomly stopped working. When computer is powered on or i plug the keyboard in. 3 led lights blink twice and then nothing. Ive tried restarting the computer. Plugging it into different usb ports. Everything i can think of. Someone help please?: Have you tried plugging the keyboard directly to the PC keyboard port and not thru the adapter?I'm assuming the desktop has a P/S2 port. If yes, then it is possible the keyboard is drawing much more power than the USB ports can provide. Try the following: 1. Check to see that all pins in the keyboard connector are straight and none broken 2. Use a different USB adapter If none of these works, you probably have a dead keyboard.

Q: I have a two year old laptop. Being that it is white, it gets dirty very easily. Recently I have been bothered by how nasty the little areas beneath the keys on the keyboard probably are. How can I clean my keyboard at home without taking the keys off? Do any of those keyboard vacuums work, and if so, which ones? I know about the compressed air you can buy and whatnot, but wouldn't that just push the dirt around beneath the keys, not get rid of it?: I use a qtip with a little rubbing alcohal (not too wet) on it to go between the keys.

Q: I was just wondering if keyboards are universal or what: I think the qwerty keyboard is the same everywhere. It's qwerty everywhere. Haha. Go on it's you turn to laugh now.

Q: I love my acer but i hate the keyboard. It works fine and nothings broken but its cheap, hard to type with, and i just need to replace it. Can you replace the keyboard of an acer laptop with a better keyboard from a different acer model?: go okorder

Q: Did i lock somthing how do i fix it . right now im using onscreen keyboard, here is the alaphabet ysig keys abcdfghjklmnstvxyz thn more: Keyboards will eventually go bye bye. Unfortunately you will have to either live with it or buy a new keyboard. Otherwise you could try air-dusting the keys.

Q: Can you please help me??I have just returned to work from my lunch break and the icons on my keyboard have changed. To get the @ sign I have to press shift and the number 2. I don't even have the pound sign anymore. The keyboard works ok when using the internet but not when I am writing an email. Please can you help me.: You keyboard has gone into English setting instead of American, my keyboard turns American sometimes (I am English) You just have to go sort it out in the control panel. Go to the keyboard section, or just try restarting your PC it works for me

Q: I bought a new wireless mouse and keyboard yesterday and it was working fine, when I switched my computer on again last night the keyboard and mouse didnt pick up a signal, do you think i should take it back to the shop and get a refund?: Try new batteries first as the person said before, make sure you got a clear range i dont know if its a IR InferRed (needs a clear view point) or 2.4GHz one (needs a set distace to be clear)

Q: I need to prepare a presentation on innovative I/O devices. The device I have selected is Dynamically controlled OLED keyboard. My teacher kind of rejected it saying that as it has a ASIC chip, and it process the signals, hence it is not a pure input device.Well I need to know if it has a processor or not?? :/here is the link: All modern PC keyboards have a tiny dumb CPU inside

Q: Heyaa,what's the best gaming keyboard?prefer lit keys asswell :)Greetings :): Logitech Gaming Keyboard G510

Q: also do u know any keyboard shortcuts?: On my computer, it's similar to the 2nd key on a scientific calculator. Look at the color of the letters on the Fn key, then look through the rest of the keyboard to find symbols in the same color. Hold down the Fn key, then press the key with the same colored symbol and see what happens. On my computer, I can quickly check the battery life and adjust brightness. I hope this didn't confuse you any more.
