Question about Microsoft Natural Ergonomic 4000

Water Damage I have managed to pour a very small amount of water into the number pad of the keyboard. The keyboard is now totally dry, including the inside as i have had a look, and removed the remains of last year?s lunches. Unfortunately some of the keys are no longer working and a few key presses register with wrong commands. Please see bellow: a = a A = a or a i.e. neither shift key works b = b c = c c actually is c + alt d = d e = er f = (space) g = g h = h i = i j = k = kl l = l; m = m n = n o = (show my favorites) p = p q = q r = er s = s t = t u = u v = v w = we x = y = y z = z Esc = (question) F1 to F12 = (Unknown F Lock locked on and Function Key doesn't work) Backspace = Return = Shift doesn't work as stated above Right Ctrl = # (Possibly + Ctrl) Right Alt = Alt Command Menu = (Question) Space = (Space) Left Alt = Alt Start = Start Left Ctrl = Ctrl Caps Lock = Caps Lock Tab = "F1" Numbers row ` = ` 1 = 1 2 = 2 3 = 4 = 4 5 = . 6 = 7 = 7 8 = 8 9 = 9 0 = - = - = = = Number Pad 1 = 12 2 = 1 3 = 4 = 45 5 = 4 6 = 7 = 78 8 = 7 9 = 0 = (Return) . = Enter = + = - = * = / = Num Lock = / + Num Lock Insert = Home = PageUp = PageDown = End = Delete = Only Right Arrow Key works Favorites Keys 2 4 & 5 works Volume up works Volume Mute works Web/Home = , Search = Search Mail = Mail Some of the double keys might be due to me dismantling the keyboard, but the contacts and the rubber '****' are back in the right place. Any one got any ideas i would be grateful. Would be a shame to throw away as it is a really nice keyboard. Regards

I'm on my 4th Microsoft Ergo 4000 keyboard. All the previous 3 of them have been junked by none other than spilt water (not hot and not very cold), thanks to my 3 yr old daughter. I've tried taking the keyboard apart, blow drying and putting it back together. Doesn't seem to work. Junking seems the only option and I'm not pleased to say the least (now that they're at $70 at Best Buy)... I'm astounded that they are so succumbale to split water (leave alone other liquids)... A deliberate flaw to ensure repeat buys?

A colleague spilt coffee on the left side of this exact keyboard. after going from not working at all and painstakingly cleaning and drying the internals I realized that, the liquid was hot enough to burn away the circuit path for 4 keys on the flexible plastic pathway, thus rendering the keyboard a total loss. I remember being able to basically hose out my DEC keyboards and hang them out to dry overnight, but even key by key care isn't good enough... cut your losses and replace it with new... It's still in production..

Microsoft's keyboards are notoriously susceptible to this -- it seems like sneezing on them will damage them. I went through several of these keyboards, even attempting careful repair, before hanging it up. Not good news, I'm afraid -- I suggest Logitech products which my students can't even break.

How to take apart canon pixma 432. Spilled soda in it, need to clean inside.


Hi Daniel,
Let me say, up front, that I am not a printer guru. My background is in biomedical electronics, but this procedure works in most applications. Take distilled water and pour a small amount into the area where the soda was spilled. Wait a few minutes to allow the water to dissolve the dried soda. Then pour in more distilled water to flush out the residual soda. Allow to dry. The water should rinse out the soda, and when it dries it will leave no contaminates of its own. This procedure works well on medical devices such as telemetry transmitters and cell phones that have been spilled on. I hope this helps. Thanks for asking Fixya. Dan

Tip

Spilled liquid on Keyboard!


1. Purchase plastic keyboard cover. 2. Keep coffee etc. anywhere not near keyboard.

For spill, unplug keyboard. If non sugar liquid, invert keyboard, shake or tap gently. Wipe with lent free absorbent cloth while still inverted. If soda or coffee with sugar, pour 1/4 cup of clear clean (distilled the best) water onto keyboard (yes), Then invert. Let dry a minimum of several hours still inverted. I cheat with a hairdryer on low 6-12 inches. After keyboard is completely dry (and cool). Plug in after turning computer off, restart, test all keys, including shift, option etc. If keys miss or don't work buy new keyboard and cover! Aloha, Cliff

How to Clean the Laptop Keyboard


The following will completely solve keyboard problems and return the keyboard to perfect operation.
This will require about 2 hours time once you have collected the proper cleaning materials.
Cleaning materials:
  • Cotton swabs
  • Cosmetic foam rubber cleaning pads ( use only with naptha (lighter fluid), NOT alcohol)
  • Paper towels
  • Rubbing alcohol
  • Water
  • Lighter fluid (naptha)
  • Fine tipped tweezers
  • Scissors
  • Kitchen strainer
  • Household cleaner, Windex or equivalent
  • Super Lube Dry Film spray (critical - DO NOT SUBSTUTUTE !) K-Mart automotive.
  • This is a PTFE (teflon) based lubricant which dries perfectly DRY and is ideally suited for this application.
Proceed as follows:
DISASSEMBLE:IMPORTANT: Make a keyboard map so you know where each key goes.Carefully pry each key loose with a small screwdriver and place in a container. They pop off. DO NOT use excessive force. There may be a small rubber piece for each key. Remove all of these and place in a separate container. CAREFUL, these are small and like to jump away.CLEAN KEYBOARD ( do this well...... you will be wonderfully rewarded ) Clean the keyboard with cotton swabs SLIGHTLY DAMPENED with water. Replace these often and BE SURE they are only slightly damp. If they are too wet the excess water will contaminate the keyboard through capillary action. This will clean all water soluble contaminants like Coca-Cola, coffee, and sugar residue. For the very small places, cut the foam rubber into small pieces and use the tweezers, again SLIGHTLY DAMPENED, for cleaning. You must clean each and every key space, inside and out, this is critical since this is where the key touches and moves. Repeat this procedure again using rubbing alcohol and cotton swabs but NOT the foam rubber as it disintegrates when used with alcohol. Finally repeat this procedure using naptha (lighter fluid) and foam rubber. You can clean even the smallest key guides with small pieces of foam rubber and tweezers. This action will remove any petroleum based contaminants as well as the grease that is sometimes used on the wider keys which may have guide wires, for example, the SPACE BAR.
CLEAN KEYS:Some keys may have wires attached and some grease on them, clean these first with cotton swabs and naptha (lighter fluid). Remove all traces of the grease. Place all keys in a kitchen strainer. Spray with household cleaner and let stand for 5 minutes. Rinse thoroughly with hot water and place keys on paper towels to dry. Let dry completely.
CLEAN RUBBER COMPONENTS:Place all rubber components in a kitchen strainer. Spray with household cleaner and let stand for 5 minutes. Use stopper in the sink so that you don't lose these if they jump out of the strainer. Rinse these thoroughly with hot water and place on paper towels. Fold the towels over and press to squeeze most of the water out of the pieces. Let dry completely.
LUBRICATE KEYS:Place all keys bottom-up on a paper bag. Lightly coat the keys, at a 45 degree angle with Super Lube Dry Film lubricant. Do this from all 4 sides to assure penetration and coverage into the small and critical guide spaces inside each key. Let dry ( this happens nearly instantly). DO NOT overdue this step as the carrier solvent may affect the plastic.
LUBRICATE KEYBOARD: Mask off the laptop with paper and scotch tape. Apply lubricant (as above in LUBRICATE KEYS) to the keyboard and let dry. All right, you now have perfectly cleaned and lubricated keys, keyboard, and rubber components.
REASSEMBLE:Place all rubber components into the keyboard. Install keys with wires. Make sure wire is secured in the key, usually snapped into place. Place ends of wire in the guide slots adjacent to the key location as you align the key. Firmly press down to snap the key into place. Install the rest of the keys by aligning and firmly pressing down.

I spilled I tea on my Gateway FX keyboard and mousepad. The keys are working now but I'm worried they will get sticky. I cleaned up as much as possible by patting with a towel to soak up the tea. ...


Before you do anything, unless it is already dried, (turn it off first!) turn the laptop upside down and gently tap the back to coax any liquid out. Then do NOT turn it on until it is totally dried. You can clean the keys and pad it with a DAMP (NOT wet) cloth with plain soap and water. Be careful not to get any water down into the keyboard itself so it doesn't short it out. However this will not clean whatever liquid may have gone inside. Hopefully none did else you could end up with a bigger problem...

Assalam o alaikum. my cell drop into water tommorrow next day working right.but now many of buttons are not working??? what i can do for this? Thanks


Number 1 rule if your phone gets wet... DO NOT turn it on.
Remove the battery from the phone. get a small ziploc freezer bag place phone in bag pour uncooked grains of rice into bag. Enough to cover phone completely. Close bag. Let it sit for at least 2 days.
This is to absorb all the moisture from the phone. Remove phone, insert battery and try using it. It may work. But you need to wait until your phone is completely dry before attempting to use it.

Key pad problem letter e not always working vacum and blew keys no changes


Remove all power, including battery.
Take a soft brush and some warm water with a mild detergent (just a bit)
Soak around the area with the key problem - is probably coffee or pop or something inside the thing.  Wet it down well, getting the brush into the key area and under it.  
Shake all the remaining water out of the keyboard and blow dry or let sit on top of a warm TV for an hour to dry.
Try again.
Remember that water and electricity don't mix.  Water must be completely dry before powering up.  Electrical components can get wet but just don't allow power through it at same time.  When it dries, should be fine!
I have completely soaked keyboards and stuff to no harm!
Good luck, hope this helps.

PS.  There is also the possibility that the carbon is worn off of the contacts as well.  All keyboard keys can be removed if careful, just pry up on it gently and see if you can remove a clip, or bend a little clip in with a tiny screwdriver to remove the key for inspection and cleaning.
Usually they'll just pop off though.

My mouse pad will not move my cursor on my computer


If your mouse is the older ball type hold the mouse level about 12 inches off the pad and move the ball on the underside of the mouse with your finger. If the cursor moves you may need to simply clean any dust from inside the device and clean the ball. Open the open to release the ball. Theres a round plate on the underside around the ball. Turn it to the open position a remove the ball. Clean any dust from inside with canned air or a soft brush. Clean the ball with a small amount of alcohol and let dry completely. Replace ball and plate and you should be ready to go.
If you have an infrared mouse, your mousepad may be too glossy. Dry a pad with a dull finish.

Hello expert


try cleaning it before you mess with any settings.

Cause:
Your keyboard or number pad may collect dust and other deposits from regular use. Occasional maintenance helps keep the device looking clean and functioning properly.
WARNING: Before cleaning any electrical device or equipment, ALWAYS remove the device from its power source.

Solution:
  • For cordless keyboards or number pads, remove all batteries before cleaning.
  • For the diNovo Edge (a rechargeable keyboard with a built-in, non-removable battery), or any other similar device, switch the keyboard OFF before cleaning.
  • For corded keyboards or number pads, shut down your computer and disconnect the keyboard from the computer before cleaning.
Keyboard and number pad cleaning suggestions:
  • Use compressed air to blow dust and other debris from between the keys. Logitech suggests using an air duster squeeze bulb specially made for keyboard cleaning to limit the force of the air pressure.
    NOTE: Avoid using high pressure air hoses and nozzles. Excess air pressure can remove keys or cause other damage to your device.
  • Use a small tipped vacuum cleaner to remove dust and other debris from between the keys. Logitech suggests the use of a small tipped vacuum cleaner specially made for keyboard cleaning. Many come with USB power cords and can run off your PC or laptop.
    NOTE: Avoid using vacuum cleaners other than the type previously described. An excess vacuum level and/or large vacuum tip can remove keys or cause other damage to your device.
  • Use a dry, lint-free, non-abrasive micro-fiber cloth to gently wipe clean the surface of your device. Logitech suggests using cloths which are specially made for keyboard cleaning.
    Note: Avoid using dusted disinfectant cloths or cloths dampened with liquids unless specifically designed for keyboard cleaning. Many cleaning solvents, chemicals, and other liquids can cause electrical and/or material damage your device. This includes leftover residues which can eventually damage your device over time.
Additional information:
Many consumer electronics stores and online re sellers offer third-party computer cleaning kits which include dry wipes, swabs, air duster bulbs, and micro-fiber cleaning cloths. Some higher-end cleaning kits come with keyboard vacuum cleaners, and/or product-safe disinfecting liquid for dampening wipes, for use in disinfecting the surface of the device. These liquid disinfectants are supposed to be non-conductive electically; quickly evaporate from the sevice and leave no residue. Logitech suggests you make sure these characteristics are plainly stated and guaranteed on the product package. These specially made keyboard cleaning kits are highly recommended.
IMPORTANT NOTES:
  • DO NOT pour any liquids onto the device.
  • DO NOT submerge the device in any liquids.
  • DO NOT use a dishwasher, ultra-sound cleaner, or any other washing machine to clean your device.
  • DO NOT remove keys from the device.
  • DO NOT use cleaning solvents. Many cleaning solvents contain caustic chemicals which may cause damage your device.
  • DO NOT use drying machines, fireplaces or ovens (even set at lowest temperature) to dry moisture from your device.
Removing keys; submerging or pouring liquids on your device; using washing machines; exposing your device to excessive heat; or using caustic cleaning solvents may cause permanent damage to your device and will void the warranty.
