Question about Microsoft Natural Ergonomic 4000

3 Answers

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.

I spilled milk on my keyboard and now the keys are all messed up when I type, and pressing any button tends to make my computer shut down or sleep. For example, pressing "R" results in...


Well if you spilled milk on it there is only one thing to do: take apart, wash, wait for it dry, and hope the best.
Find all the screws on the bottom (some might be under stickers or the rubber pads), unscrew them all, and take apart the case. Iside you should find a small panel and a double layered foilage thingy, with printed tracks on it. Remove the small panel and wash everything else with warm tap water. Dry it with a towel and wait for it to dry completely. Then put back together and try it out.
There's not much you can loose this way, if this doesn't work you'll have to buy a new keyboard anyway.
Good luck!

Sounds like your keyboard is sticking

Unplug the keyboard and do the following

Look on the bottom you should see some screws, remove the screws and leaving the keys facing down, pop the two pieces apart.

Leaving the electronics aside you can now continue with the following instructions
Ok, once you have the two pieces, all of the keys should stay in there proper place, take and soak that in the sink with some soap and water.
Moving all the keys to get the water to flow through.
Then dry off the Keyboard and vacuum all the excess water off, then replace and screw back together, you should be good to go.

I wouldn't recommend a dishwasher, this could get to hot and melt the keys

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.

Sticky keys


You can try cleaning the keyboard. most keys can be removed easily by just pulling them out.
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 SCACE 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.
