Q: Hello,I am planning to buy a wireless keyboard and a mouse . Do wireless keyboards use batteries if we're not using them and what you say is it advisable to buy cauz for few days ill b using it and wat minimum range it ll give me.Regards,Rahul
as long as i know it all depends on the keyboard you buy, id it has illuminated buttons then it will use the battery more and yes they keyboards use the battery all the time when the computer is on, but if its off it doesn't. even though keyboards don't use much power and you don't need to replace the batteries very often. the range will vary from the models and makes. id suggest you something simple since (i guess) you're starting with the wireless tech accessories. id suggest something from Logitech, this brand have never failed me and it is a fair price for value.

Q: I have the first kindle fire and I was wondering if it can have a keyboard? Like there's wifi so shouldn't I be able to buy a wifi keyboard for it?
My kids just love our Kindle Freetime unlimited on their Kindle Fire
Q: I started up a computer and it says press the Any key. I have looked all over the keyboard and I can't find it!
keyboard buttons are on a keyboard. press any button. by the way:
Q: can anyone read this number tabs for a keyboard?
erm. it seems that this is a guitar Tab I'm not really sure that keyboard could play it. but i'm sure that guitar can play it.
Q: I was chatting with a friend online when suddenly my keyboard went insane. When I'd press I it would immediately go to the beginning of the sentence and leave 'iurw' behind. So instead of living it would be 'liuwf' And when I'd press K it would close the window that was currently on top. I didn't do anything before this happened and I have no idea how to fix it I restarted my laptop but it's still going crazy. Does anybody know how to fix this? Also, my laptop is Windows 7.Thank you!
Maybe you have some sticky keys or the circuit board of the keyboard is messed up. You should try inspecting your keyboard. If there are no visible errors, open up your laptop and see if the keyboard is connected properly. If still no problems appear, try replacing your keyboard.
Q: I am trying to make a PIANO KEYBOARD out of a Regular PC Keyboard, thus, I want to dissasemble a PC keyboard and make a 32-key PIANO keyboard out of it, I'd use homemade piano keys for the piano keyboard's keys and arrange it like a regular piano keyboard (so i can use it perfectly with my MIDI synthisizer), the question is, how can I arrange the homemade piano keys on the pc keyboard's switch pad in a horizontal way, unlike the original orientation of the regular keys? Since the PC Keyboard's keys (at least 32 keys) are not aligned respectively, can I possibly use metal strips to adjust certain points on the keyboard's switch pad to align at least 32 keys horizontally?
It would work as long as you would not attempt to pierce the pcb inside the keyboard (assuming that you have one, of course). Yet tt would be a lot more effective, ergonomic, reliable and aesthetical, if you would just make a custom enclosure for your home made MIDI keyboard. Go for wood, or organic glass, whichever fits you best. After all, if you are able to make piano keys, i think that making a box of some-kind of material and fixing the pcb on it + keys would not be too hard. A tad of planning, half-a day of work and tu-dum!
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: I got coffee on my keyboard. I was wondering how to keep the keys from sticking? I whipped everything off but, I am sure later when I get off the keys will become hard to push.
Well, first do what the other posted said, but be careful when assembling it back together as you need to align the sensor part of the keyboard nearly perfectly.
Q: See if the welding module is faulty
Install keyboard. One thing to note here is that you must wait until the alcohol evaporates
