The function key with Fn on it is to switch on all the features on your computer with those function keys which with little icons in the same color as the text Fn on the Fn key. You just need to press the Fn key and press those keys to switch on those features.
The windows logo key with a windows logo on it is to open some windows shortcut. Such as Windows Logo + E opens the Windows Explorer if you press the E key while holding down the windows Logo key.
Here is a link about windows short cut keys. http://support.microsoft.com/kb/126449
You can see there are some short cut keys with a combination of Windows Logo+ something. The windows logo key is the one with a flying windows logo on it.
The pop-up window key which looks like a mouse pointer on a menu does the same thing as right-clicking the mouse to bring up a pop-up menu.
If it will not snap back on i am assuming the retainer is broken or missing. Carefully remove another key that you typically do not use such as the one between right alt and control. You will see what an unbroken corretly placed retainer should look like. If the retainer for your x key is lost or broken you may remove the retainer for the key you just removed and your x key should go right back on. If you can find the old retainer or it has come undone, simply reinstall it identically to the working key used for comparison. If there is no internal damage to the key, this should fix your problem.
If you wish to replace it altogether or would like to fix the key used to repair the damged key, you may order replacements for 3-4$.
Hope this helps.
Yes people it can be fixed
by yourself at home, cheaply and easily. I’ve got an Edirol pcr-80 &
prc-a30. Both have had intermittent key troubles and keys that just don’t work
anymore or low/high level compared to other keys. These problems seem to start
after a year or so. I’ve paid hundreds of dollars getting them fixed until I
tried this on a whim. The contacts under the keys are a carbon-based contact so
cleaning them with metho/alcohol just dries out this carbon. Some people say
cleaning them with a pencil easier helps and it can do slightly but not
properly. What you need is “Graphite Powder”. (Link for a picture of a appropriate
product – just cut and paste it in your Internet heading bar, or Google image search
graphite powder…) http://images.google.com.au/images?hl=en&source=imghp&biw=1024&bih=1080&q=graphite+powder&gbv=2&aq=f&aqi=g1&aql=&oq=&gs_rfai= Graphite powder is a dry
fine powder that is conductive and perfect for the job. You can purchase at any
locksmith – maybe a good hardware store, and it is sold as “non liquid
lubricant for locks and machinery.” All you need to do is unscrew the case, remove the springs
that hold the keys in, remove the keys. (White keys first then black keys. Keep
in order.) Peel off the rubber strip under the keys and turn over so you can
see the little carbon nipples that touch the circuit board. (2 for each key)
Pour a little power out on a sheet of paper and use a cotton tip bud to apply a
little powder to these. Now apply a little to the carbon contacts on the circuit
board where the little nipples touch. Do all this with your midi keyboard
plugged in to your computer/synth etc so you can hear how you’re going with
getting contact before you put it all back together. You might get a key or two
going off when doing this because the graphite power is making a continuous
contact across the circuit board. Just blow/lightly wipe away excess to stop
this but you want to leave all the contact points evenly (if slightly) coated.
Try touching the rubber strip contacts with the circuit board contacts to see
if you can get a sound. This can be a bit tricky to line up and get an even
contact. This sorts its self out when everything is back together. Now put back the rubber
strip. I used I tiny screwdriver to help push the rubber guide back in the
holes on the circuit board. Now put the keys back (black first – with the short
springs then white keys with the longer springs) screw the case back together
and let me know how you went. This I think will dry up
again in time but if you get a good bit of use out of it you can just do it
again… For free… Garthy.
If you feel somewhat technical you can check the internal connection on the keyboard to be sure it is seated properly.
Has someone poured your keyboard a cup of coffee? Ask the kids.. give them a serious face so they fess up.
If all else fails send it to ACER if it is still under warranty. If not, the keyboard can be purchased online from $40-70 dollars. With a typical installation fee you are looking at @ $175 repair fee. (barring the motherboard being the culprit)
Never been inside one of those keyboards but many keyboards have a printer circuit board with plastic film layers over the circuit board. There may still be juice trapped in the layers shorting out the key or you may have burned out the key when it shorted out. I've seen that many times on Microsoft keyboards. You can always take the keyboard apart and check out the 0 key.
Only solution here is to unplug the keyboard from the mother board. Just take apart the case and look for the ribbon cable going from the keyboard to the motherboard, and take it out. Please rate, thanks!
