How do I remove "return" button which stopped working


The button itself is not the contact.

Unscrew the two halves of the keyboard by locating the screws under the rubber feet on the bottom.

Turn it upside down.
It should come apart the top key section, then a rubberised mat then the PCB then the bottom case.

When you press the key a rubber dome with a conductive pad presses against the contacts on the PCB.

Clean the contacts with switch cleaner and reassemble.

Letter "p" key not working.


pull the key out of keyboard, Press the rubber directly using any material that would fit there and check if it works...If it doesnt work then probably the place where letter P is placed is damaged...

How do I open up my Microsoft Sidewinder so I can clean/repair it?


on the bottem of the mouse there should be 3 or four small screws, if they are not visable they will be hiding under the small rubber feet, undo all of the screws using a small philips screw driver, the 2 sections of the mouse should gently pull apart, if not then get hold of a thin flat object ie a knife and gently prise the 2 sections apart you may hear some clicks as it opens, dont worry as long as you are gentle it is just the plastic casps coming apart, once opened you should hopefully be able to repair the problem, and put the mouse back together the oposite way you took it apart. hope this helps.

Your on the right track. Check for grease on the contact. Clean the circuit board surface with alcohol and a q-tip and also the rubber/metalized switch.Wipe clean with other end of q-tip. Try the key again.

Key button got pluged off


You probably broke a little tab that connects the letter to the actual button.
Just get some of that thick (foam) double sided tape. regular double sided tape wont work.

good luck

Keys: r, t, f, g, v, and b have stopped working. Previously they started working after about 30min, but now have stopped completely. I have cleanned the keyboard w/ compressed air and they still don't...


usually keyboards are pretty simple to clean once you take them apart.

There is a rubber (normally) surface with some black conductive poins under each key. un screw the keybard clean the contacts and put it all back together.

Note: be careful certain keyboards do not have a way of "holding" the keys in place once you take them apart. So if you arent in the mood of putting a big puzzle back together and losing 30 minutes rearranging keys (wheres that damn ~ go again?) be very careful as you pull it open.

EX110 Keyboard: Some Keys don't work


GandalfUK,

What can be done depends greatly on WHAT was spilled on the keyboard, AND what your experience with electronics is.

All of the keys you indicated are on the same key row as each other. The way a keyboard works is that there is a grid pattern of electronics traces(lines) that run below the membrane (Rubber or plastic seal) just below the keys. The controller determines which key you push by checking for what column connects with what row.

Well since all of the keys you have indicated seem to be from the same row, I would say that something damaged the trace for that row.

Which leads me to believe that what he spilled was something acidic (Soda, orange juice etc..)
If you have experience with electronics you can remove the control board from its casing, be sure to remember where EVERYTHING came from (Draw yourself a diagram if you have to) then inspect the board for damage. You should be able to SEE the grid patter of contact pads. there are several rows, the one you want is 3rd from the bottom. If there is OBVIOUS damage your in business. clean it up and you can buy whats called a trace pen from an electronics specialty store. This is much like a ballpoint pen but instead of ink it has metal flakes suspendend in an electrically conductive epoxy. Draw in the gap in the trace with this pen and let cure usually 5 minutes but follow the curing time on the pen if different. then you can reassemble.

If you don't see any damage then you have to use a multimeter to narrow down the location. If you don't have a multimeter or the experience to track the trace to an open. Then it would likely be cheaper to just purchase a new keyboard. Not sure what they cost in the UK but their about $30 USD which if the exchange is what I remember is about 12 Pounds.

Hope this helps
Dave

Keyboard not responding or typing random letters


You have stuck keys from when you removed to clean. Remove the stuck keys and see if it works OK when you press the rubber cap instead of key
The back space one may have a link under it if it is a wide one ensure it is fitted correctly
