A amount pad, or "numeric keypad", is large because entering a sequence of numbers with a little hasty taps. It's been criterion above computer keyboards because many years. besides computing has changed. The mouse has gone from a niche gadget ought a continual complement ought typing and the chief instrument because navigating across many kinds of data. The amount pad, conversely, has gone from a sometimes-noticed-and-handy reason outboard of the letter because the calculations that comprised much of an early PC's vocation ought a frequent roadblock because the mouse. It has ought be continually reached can and can demand an awkward off-center placement of the chief keys at front of the user, or possess the mouse out of a comfortably low keyboard drawer entirely.
1) choose a keyboard ought modify. There's no much point if a identical alike keyboard with no amount pad is affordable. The keyboard ought eat nothing other than the amount pad keys above the amount pad side, which is ought be chop off. The plot will be simpler if the keyboard has no specific buttons, fair the natural keys.
2) inspire the keyboard from the computer.
fetch off the computer and unplug the keyboard that you're going ought modify. if you like, plug at a backup keyboard and restart the computer if you'll want it during the project.
- Swapping a USB keyboard chiefly doesn't demand a restart, besides that will always repair any problems. And using the not-yet-unplugged old keyboard is the best means ought catalog definite you can finish the computer down cleanly.
3) receive the keyboard ought a vocation piece away from the computer. discover a place where it's OK ought disperse flexible shavings and maybe scrape something with a saw. The workspace ought also be well-lit so you can visit what you're doing, neat so that you don't Mrs things, and quite clean so that you don't contaminate the keyboard's inner workings. There ought be an electrical outlet finish because a vacuum ought clean up messes throughout the project.
4) Prepare ought work.
clean your workspace. Plug at the vacuum and place it ought to absorb across a nozzle and preferably a clean soft bristle reason which will be improve because dislodging keyboard clay and flexible shavings. accumulate the blower and canned attitude because cleaning accumulated clay from the key assemblies, saw(s), screwdriver(s) ought accommodate the screws above the bottom of your keyboard, vocation gloves, and safety glasses.
- Some electronics are sensitive ought static, so a warm, damp appointment used to be best. You could allow a humidifier flow at the piece because a little hours first if the attitude is dry: heated winter attitude chiefly is. You could utilize a wrist strap and other antistatic devices while handling the electrical parts, besides they're unwieldy, and keyboards are vigorous and inexpensive though electronics go.
5) hole the keyboard.
You'll want ought inspire entire the working parts from the universe amid the amount pad and the other keys so that the instance can be chop without damaging the insides with less-than-ideally placed or stress-focusing ragged cuts ought mechanical parts, or with breaks at electrical circuits. ought conduct that, you eat ought hole up the keyboard. Before you receive apart something complicated or unintuitive, or once you note that you eat (seeing, because instance, an array of different-length screws), catalog a reminder of how ought place it back together. receive notes or a digital picture.
- Turn the keyboard upside down and inspire the screws from the back.
- Sometimes, a flexible instance can be held together partly by one or more screws hidden beneath a sticker. if so, poke into and slice almost the edges of a almost depression or lump at it with a little knife, or fair poke a screwdriver through. at an piece that used to show, gently elevate up the border of the sticker with a knife (a sincere one will always do) and hide it up, lifting more than rolling back so though no ought crease it, impart a well stoop that won't proceed back down, or wreck the surface. if you inspire it entirely, place it sticky-side-up out of harm's means until time ought substitute it.
- Sometimes a flexible instance can be held together by an interlocking tab can an edge. if so, elevate out the other border first or stoop one or both mating parts ought liberate it.
- Sometimes a instance can be held together by screws extending from the sumit into the bottom, such though screws beneath the spacebar, which pops off, above a Microsoft natural Ergonomic 4000, or screws beneath stickers.
- When you eat the bottom free, place the keyboard above a desk ought finish disassembly so its parts don't dump out ago you visit how they entire accommodate together.
6) Disassemble the keyboard.
place the keyboard above a desk keys down: entire the parts accommodate into openings and projections of the sumit part, with the bottom normally fair pressing them into place, so gravity will possess them nestled at the sumit until you receive them out. Once you can grow something out of the external case, there's no want ought disassemble it further. It's best ought receive out entire of the keys and big, loose items so they don't grow broken and the flexible shavings you'll catalog by cutting the instance can be vacuumed away, besides anything little and firmly mounted entirely away from the amount pad can stay. You'll note the following parts, from the now up-facing bottom of the keyboard ought the top:
- Case screws. You already loosened these ought liberate the bottom cover. receive them out and place them aside or carefully place the bottom aside with them silent at the holes so they don't autumn and grow lost.
- Bottom cover.
- Multi-layer keyboard membrane place of thin, non-stretchy flexible with electrical circuit traces. possess this together so that clay doesn't grow amid the layers and place it aside. It's fine and maybe susceptible ought water damage, so don't clean it besides ought gently clean off any excess dirt. note that it has holes which accommodate can pegs at the sumit cover ought possess it from sliding almost beneath the place of keys which is supposed ought rap it at special places ought mean what is being pressed. if it is held down somehow, inspire whatever is holding it down. Unscrew screws and wiggle it past or chop off any bits of flexible holding it. conduct no chop the membrane itself! note that the keyboard has an electrical connection ought some electronics themselves connected ought the USB cable. if those are permanently connected, inspire them from the keyboard with the membrane. if it's removable, bridle that it can mix sole one means or letter how it connects. above the Microsoft natural Elite keyboard, the membrane has a place of contacts can an border that publication amid a rubber pad at a pocket and a place of contacts above the border of a rigid printed circuit board that lays can it.
- One or more silicone sheets of dome switches ought furnish one dome per key. note that the domes see the keys, which used to kink them ought rap the membrane, and that, alike the membrane, they accommodate can pegs ought possess them from sliding around. They don't themselves embrace any electrical parts, so clean them or flat wash them gently if you like, besides catalog definite they are dry ago reassembling the keyboard.
- One or more key assemblies - banks of keys at flexible frames. above an old keyboard, these maybe eat lots of clay that energy flat interfere with their flat travel. Blow it out from amid the keys with a little blower or canned air. Wash them if you like, flat at a dishwasher (away from the heating element, which could dissolve them) besides catalog definite they are dry ago reassembling the keyboard. It's no simple ought inspire the keys from their flexible carriers and you energy recess something trying.
If the keys of the to-be-removed amount pad are mounted at a natural conference with others, such though the navigation keys, inspire the keys at the leftmost queue of the amount pad because room ought vocation at cutting the assembly. It's best ought place the danger of mistakes closest ought the keys you don't want, and, depending above the keyboard's design, a flexible rib remaining above the number-pad aspect will help anchor the truncated key conference securely at place with the truncated keyboard case. above the Microsoft natural Elite keyboard, a key is best removed by squeezing catches above the back and pushing it across the frame.
In some keyboards, such though the Microsoft natural Ergonomic 4000, the key assemblies can be affixed ought the sumit cover. It's OK ought abandon them there, besides receive extra anxiety ought grow out the flexible shavings back cutting off the amount pad so they don't interfere with the keyboard's operation.
- Num Lock, Caps Lock, and Scroll Lock indicator lights. These can be attached ought another electrical conference or, though with the Microsoft natural Elite keyboard, fracture above contacts above the membrane. bridle the orientation of the conference and its contacts. flat if it appears symmetrical can first glance, it can eat ought proceed back at a special orientation. letter which goal faces a special means above tape attached ought the conference ago removing it if there is a danger of confusion.
- Cord and chief circuit board. above the Microsoft natural Elite keyboard, the line is woven across little little gaps at the sumit cover ought circulate and console stress from pulls above it ago chief ought the circuit board, which connects ought the membrane with an border connector that rests against the membrane, which at fetch is pressed down by a rubber pad. place this assembly, and the pad, aside.
- Spacebar and its divide dome switch. Some keyboards can no eat a divide dome switch or mounting because the universe bar, besides the Microsoft natural Elite keyboard does. receive out the dome switch so it doesn't accumulate flexible shavings (dirt tends ought cling ought the silicone), and inspire the spacebar too.
- Top cover. if you've removed everything electrical from it, you can wash it. You can wash the bottom cover, too.
7) Reassemble the vacant keyboard sumit and bottom covers. Screw them together. utilize can least the screws finish ought the gap amid the navigation keys and amount pad. You'll chop across the sumit and bottom covers together so that the chop parts friend neatly.
8) badge the vacant keyboard sumit and bottom covers because cutting.
at reason ought creating a straight, square profile, receive anxiety ought keep the stiffening flanges and ribs finish the amount pad. Wide masking tape is large because marking straight lines: place it above the aspect ought be kept, with its far border indicating the place ought cut. It stays quite straight while stretched taut (stretch any tape from the center of its width, quite than across one edge, ought decrease curving) ought automatically flourish a straight queue and can decrease lifting of little bits of plastic, i.e., burring, can the chop edge. On the Microsoft natural Elite keyboard, there is a squarish stiffening flange extending inside can the border of the sumit cover's hole because the amount pad. possess this because strength. tear off little inches of tape, place the border of the tape across the border of this flange (next to, besides no into, which you'll cut), and flourish the tape ship and back. If you'll utilize a long, stiff saw ought chop the case, you'll fair saw across the complete breadth can once and flourish down across the bottom cover. if not, you can want ought badge the bottom cover because cutting. You can no fair be able ought wrap the tape around, because a varying cross piece from one goal ought the other energy effect the tape no ought flourish straight around. utilize a divide slice of tape lined up with the first can the front and back of the keyboard ago the places its avenue curves. Or queue up the bottom cover marking tape with measurements taken inside from the exact border of the instance by a ruled carpenter's square hanging can that edge, matching measurements from given points can the border of the top-cover tape ought the border of the instance ought corresponding points can the border of the bottom-cover tape. (Because the bottom cover is smaller than the sumit cover, tucking into it, you can't fair standard too distances inside from the border of each cover separately).
- If the keyboard instance has stick-on or otherwise removable feet where you will cut, or above the divide you will chop off, hide them off and place them aside ought abandon the adhesive untouched, and cane them can uncushioned corners back you reassemble the keyboard.
9) chop the keyboard case.
It's fair lean plastic, so explanation much anything will chop it. besides shears used to bow and recess it. A sharp, coarse-bladed hacksaw or a backsaw will be best: place the blade flat above a flat divide of the queue ought be cut, publication and drag it somewhat firmly ought commence the kerf (take anxiety ought commence a sole distinct chop without marring the surrounding material), and possess the blade vertical though you saw across the sumit and bottom covers. no want ought publication difficult once the saw is started at its kerf: promote back and forwards gently, and allow it conduct the vocation until the keyboard instance fair comes apart. If you eat sole a little saw, you can chop the frame from one goal ought the other (watch the number-pad left flange and chop next ought it). if you eat a hobby rotary instrument such though a Dremel, you could follow the tape entire the means around. dress hand and eye protection, specially if you are using a hacksaw (whose blade can break), a saw with large teeth, or a little energy instrument (a large one used to be identical dangerous). Protect the vocation surface with something alike portion wood or an old telephone book.
- Save the removed pieces. You energy be able ought utilize divide of the removed bottom cover, specially if it was chop off perfectly straight, ought finish up the chop border of the keyboard.
- You can utilize sandpaper ought flat very-rough areas. besides it will catalog many fine, messy flexible particles. Don't fetch a quite straight, rough border into a smooth, wavy border across uneven sanding if you plot ought mix a flat, rigid cover ought the chop edge. A sanding obstacle ought include the article flat used to help flee this and the gaps it used to leave.
- Unless you're going ought glue a rigid dish can the complete chop end, you can gently almost the chop corners by stroking a flat queue almost them a little ripen because appearance. because the rounded profile will appear good, besides the chop border won't, possess the queue at a vertical plane. You could utilize sandpaper above a flat surface or at a sanding obstacle instead of a file.
- Once you've finished cutting and grinding, inspire the tape and hole the keyboard instance again so you can clean out the shavings.
10) if the amount pad is divide of a larger key assembly, chop it off. above the Microsoft natural Elite keyboard, the amount pad is divide of the identical shore of keys though the navigation keys, which you'll want ought keep. There is a rib can the left border of the amount pad. possess this, and chop shortly ought the exact of it: it adds energy and rests against the top-cover flange that was can the left of the amount pad ought possess the key conference from slipping left. chop the key conference though you did the keyboard case. badge it, similarly, ago cutting if you like.
11) Vacuum up the flexible shavings. A clean soft bristle reason used to be best, and any little nozzle used to be good, because breaking their static cling ought surfaces and sweeping away burrs from chop edges.
12) if the amount pad dome switches are divide of a larger sheet, chop them off. if the amount pad keys are divide of a larger assembly, the dome switches maybe are divide of a larger sheet. They're held at place beneath the keys by being squeezed can the edges, and their slice is soft and maybe translucently inconspicuous, so it's best ought abandon a part of an inch (cm) border beyond what is needed than ought abandon also little. be definite ought sole chop off the amount key switches, no the navigation key switches, and neat finish ought the switches ought be removed quite than finish ought the ones ought keep. utilize a sole chop with a article cutter or a full-size scissors ought flee jagged edges that can concentrate stress and tear.
13) conduct no chop the multi-layer keyboard membrane. conduct no crease it, which could fetch the layers into confront at the wrong place or recess the circuit traces, either. It has a network of circuits from which the amount pad is no cleanly separable. You'd maybe destroy the keyboard.
14) Reassemble the keyboard. You'll essentially adverse the disassembly process. This will be easiest if you uphold the front cover by edges or corners so the key assemblies can descend at fully quite than themselves resting above a table. place at the electrical controller, lights, and keys; place at the dome switches; place at the membrane; and perpendicular electrical connections (on a Microsoft natural Elite keyboard, don't overlook the rubber pad that squeezes the membrane-controller connection together). queue up entire of the the dome switches' and membrane's retention holes. Screw above the back cover. place above any rubber feet you removed and, back the keyboard is working and this plot is otherwise finished, substitute any stickers you removed. The amount pad divide of the keyboard membrane will fair hang out of the keyboard instance because now. Touching the protruding membrane can effect errors such though unwanted number-pad keystrokes.
15) examination the keyboard. bridle that entire of the remaining keys gently chew and rebound while tapped, though before. Plug at the keyboard and bridle that entire of the keys work. You can want ought restart the computer because it ought confess that the keyboard has been attached. if the keyboard doesn't work, bridle that it's plugged at ought a working port, and, if that's no the problem, hole the keyboard and examine the assembly. if sole some of the keys conduct no conduct correctly, bridle the conference finish them at particular.
16) Tuck away the amount pad's divide of the membrane.
You eat a little options because this flap:
- Wrap it below the bottom border of the keyboard and include its border at place with cellophane tape. This is hasty and easy. besides it looks sloppy. It leaves the membrane vulnerable ought contamination, specially from spills--though those aren't much of a danger at a dedicated keyboard drawer. It leaves the keyboard unsuitable because placement above surfaces that energy publication above the membrane and thereby register keystrokes, such though the user's lap. if the keyboard erroneously registers keystrokes from the flap, effort shielding one of its layers from the other with flexible wrap. You could silent tuck it under, quite than into, the keyboard. at that case, don't place flexible wrap can the place the tape is ought attach.
- Prevent it from registering keystrokes by separating its two external layers from one another and other surfaces with flexible wrap, then tuck it back into the keyboard. This looks much better, and protects the flap from the environment. besides it risks damaging the membrane and so killing the keyboard by bending and breaking it or flaking off its circuit traces, also shortly or can time. It also risks mechanical and electrical interference with the keys it's tucked under, always the navigation keys.
To conduct this, chop a strip of flexible wrap a little longer than the length of the protruding membrane flap (which, with criterion plastic-wrap width of 12"/30cm or so, will be much wider). haul the flexible wrap almost the bottom layer of the membrane flap, which needs ought be separated no sole from the sumit flap besides from the bottom flap piece finish inner the keyboard instance which it will be bent up against. link up the chop edges can the exact border and the sumit or bottom border of the flexible wrap (whichever isn't wrapped) and publication them together so they cling. possess the flexible wrap sole one layer thick and neat off any large excess extending past the membrane layer edge. A 1/2 inch (1 cm) border is plenty.
You could effort flexible tape instead of flexible wrap. It used to remain at place readily. besides attempting ought inspire it, though you energy anticipate ought effort if something doesn't vocation initially, could wreck the circuit traces--possibly invisibly--and murder the keyboard.
Turn the keyboard can and loosen the screws holding the number-pad aspect of it together, and if indispensable the others, so that the chop border of the keyboard can loosen by a little part of an inch (a little mm). stoop can the membrane flap, entire layers together, and tuck it at beneath the navigation keys' adjacent membrane. You can eat ought tuck the membrane flap at can a slender aspect ought best adapt the screws and other obstructions extending across the keyboard. abandon can least the identical border of the fold out so that it doesn't grow creased difficult and maybe shortly recess above its own. You could list up the flap, too, besides it energy be harder ought department or cover if it is rolled up and beneath stress ought exaggerate than if it is simply bent over.
- Folding the membrane into many layers (which will bulge almost the folded edges, inner and exterior the keyboard enclosure) ought tuck into a little universe will likely catalog it also thick and publication above the adjacent navigation key switches from underneath. So, you can be left with most of it tucked at and a little sticking out can the keyboard edge. Ignoring that mill great.
You could cover the chop border of the keyboard with wide, well tape such though mailing tape, a difficult cover of another material, or flat a flat slice of flexible made from the cut-off slice of the bottom cover, tipped upward. if you utilize tape, and eat ought inspire the tape, carefully liberate it from the flexible wrap or you can drag that off and eat ought substitute it. if you utilize divide of the bottom cover, you can eat ought inspire or neat down its verge and ribs, and badge its inner border because cutting by reference ought the contour of the border of the sumit cover can the bottom cover. back cleaning the mating surfaces, you could mix the dish made from the bottom cover or other rigid material with glue, solvent cement, or well double-sided tape robust because the materials involved. if glued or cemented, they used to maybe eat ought be held firmly with a implement such though a strap clamp until dry. Attaching an improvised cover with a well adhesive or cement could frustrate opening the keyboard later.
