Q:Broken computer Keyboard?
The onboard cable connector is also a big problem especially if its opened without care. make sure the connector is ok and all pins are visible. Otherwise if its onboard like Dell you will end up buying a new motherboard for that.

Q:dose the apple keyboard work with dell computers?
Although PC and Apple keyboards may look similar, there are some important differences between them. These differences exist to meet the requirements of the computer or the operating system. The Apple Keyboard Support driver included with Boot Camp provides functionality for Intel-based Macs using an Apple keyboard. The driver maps the keys on your Apple keyboard to match essential Microsoft keyboard functions. This driver is installed as part of the Boot Camp Apple Driver CD installation process. If you disable the Apple Keyboard Support driver, Windows will not recognize the extended Function keys on Apple external keyboards, nor the (Fn) key on MacBook and MacBook Pro computers.
Q:Questions about the electric (piano) keyboard?
A bit broad, but I'll take a shot 1. Materials vary depending on the keyboard. Older keyboards use simpler components such as vacuum tubes and mechanical parts (tone wheels, tines, etc.). Several are encased in wood. Modern electronic keyboards are basically computers with dedicated functionality. Of course, analog keyboards are still produced as well that use simpler parts. This is about the simplest explanation I can give without going into more detail than is available here. 2. The earliest example of an electric keyboard that I'm aware of was the Telharmonium, developed in 1897 and introduced to the public in 1906 in New York. 3. The Hornbostel-Sachs classification system places instruments into 5 categories: idiophones, membranophones, chordophones, aerophones, and electrophones. The electric keyboard would belong to the last category. Hope this helps.
Q:A question about my Keyboard?
As long as this is a plain keyboard (i.e. has no batteries inside) you can unplug it from the computer and run hot water though it. You can also pry off the keys and clean under them (they go back on by pressing them down until they click). If you run water though it make absolute sure that you dry it out. You can use a hair dryer if you are careful enough not to get it too close. A keyboard is really nothing more then a large array of switches. These switches may corrode (depending on the make of the keyboard). But generally they can have water run though them. If all else fails simply buy a new keyboard (they are relatively cheap) and call this a learning experience about drinking liquids around your computer.
Q:Some maintenance methods for failure
 scrub the key surface. Then use the vacuum cleaner to suck the keyboard again
