the power supply for keyboard is?

The keyboard gets its power from the PS2 or USB connector that plugs into the computer.

Actually no. I think there is about 5 volts DC. I guess the amount of power available depends on the computer, but it's probably very small. Maybe less that 500ma.

Do this.  Unplug the keyboard and then turn on the computer and let it start up all the way.  Then plug in the keyboard.  Your system should recognize it as new hardware and prompt you to install the driver.  (you'll get a pop up wizard that will walk you through the steps).  really  easy. \n\nIf that does not work then try uninstalling the keyboard and then reinstall it.   Go to your control panel, add/remove hardware.  Find the keyboard and uninstall.  Shut down and restart and then plug it in and reinstall. \n\nIf all of that fail...unplug the keyboard and take it to best buy.  Tell them what's going on, tell them that you would like to buy a new one but you would like them to test your keyboard first.    They will plug it up to one of their computers and test to see if it's working.  Then you will know for sure if it's defective or not.

depends on how you have your power button on the keyboard setup.\n\nsleep? hybernate? or shut down? or bring up the shut down menu?

My take:  the keyboard is probably toast.\n\nCleaning it is worth a try, but I'd start checking into getting a new one.

I think they have different power connectors, for different types of motherboards.

If your power button is bad then yes, you can probably take the button from the old one (if it is the same - not all are).  The old power supply may or may not be the same - you may have an AT supply in one and an ATX in the other.  If the power connectors look the same (the large ones that plug into the mobo) then yes, replace it.  You need not install it into the case first to see if it works, just connect it to the mobo, connect the hard drive and see if it powers up.

most don't have internal power supplies, that is the little box in the cord, some do, and no they can be removed and changed, which laptop do you have

Nothing is for free.  Peripherals you put inside your computer take certain amount of power.   Motherboard, keyboard, mouse, graphics card, hard drive, cd drive, and etc. etc. all require certain amount of power.\n\nThe issue with have a good power supply isn't about speed.  It's about stability.  Your power supply is in charge of converting the AC current from the wall to DC.  An ideal power supply will provide stable DC current with very little ripple current.   Ripple current is the deviating fluctuation that is present in all DC current provided by a power supply.\n\nAnd it is possible to have too much wattage but only in extreme cases.  Electronic device like power supplies work with tolerance levels usually given in percentages.  So two different rated power supplies built with 5% tolerance will have different tolerances.  With a lot of power you lose a precision.  With precision you use a certain amount of power.  (Analogy would be fidelity and power in audio terms.)

1. check connections\n2. check that the computer knows that the keyboard is connected to it.\n\nBut I wonder..... if your keyboard does not work, how could you type your question??

Look for the chrom colour button battery about 2cm in diameter on the motherboard, if you take that off you should see is 3v. on it.

you need to get your keyboard replaced or your motherboard.  It's a short.  Call your manufacturer for more info to get it repaired.

Try plugging in your keyboard first and then turning your computer on. Where I work they have a very out of date computer and it did the same thing. We turned the power off and plugged in the keyboard. When we turned the computer on it worked.

eBay!\n\nDo you need one with the old style DIN connector?  The REAL IBM keyboards have a big round connector with 5 pins in it!  You can use an adapter if your computer uses the smaller PS2 connection (same as mouse.)\n\nI have a few laying around, if you can't find them anywhere else.  eBay id:  a1_h2o
