Microsoft Comfort Curve Keyboard 2000 Mac Driver Reviews

This keyboard is known for key-failure problem.

What's the Cause of the Problem?

Static Built-Up?

There's a guy SMApple who wrote a post here: http://www.fixya.com/support/t3015431-microsoft_comfort_curve_2000_v_1_key. He says the problem is electric static built-up inside the keyboard. Quote:

The problems with this MS comfort curve keyboard starts when at randomsome of the keys stop working, it dose not matter how hard you pressor for how long, they just wont work, this problem is due to staticcharge build up on the thin plastic sheet/mat inside the keyboard thathas electric circuit printed on them. This new keyboard technology iswonderful and superb, the keyboard is sheer pleasure to use when it isworking, when you press the key it is quite soft and silent, so, itwont wake the baby up. it has no mechanical parts inside keyboard, ithas lots of small soft plastic **** on plastic matt that you presswith your keys so they don’t make any sound, same as in your averageRemote control. Even in this year 2010 this plastic sheet circuitboard needs lots of improvement yet, because it suffers from staticcharge build up. Microsoft seems to have opted for the cheapestquality non expensive plastic sheet circuit mat for their keyboard,probably made from some cheep biodegradable recycled plastic condoms,these cheep mats always have tendency to hold onto electric charge andwont discharge when they should, and consequently cut off circuitconnections to the keys, same technology that is used in majority ofthe household remote controls, and ,so, the reason why Remote keystend to stop functioning after a while.

His solution is to spend 15 min to open up the keyboard to discharge it, whenever keys starts to not working.

Membrance Mis-Alignment?

Another guy(stackoverflow.com) claims it's membrance mis-alignment. Also says he open the keyboard to re-align the membrance.

Reviews on newegg also has lots people saying that the keys doesn't work. Source www.newegg.com

The bottom line about the defect is that the failure is not consistent. Sometimes the bad keys just work perfectly.

Beware of Garbage Advise

There are lots of sites that give garbage advices about this keyboard. They'll say update the driver, clean the keyboard. These are not the problems of this keyboard. The problem is with the keyboard hardware itself. Also, return for replacement will probably not help. Lots of reports that say new replacement are still bad as of 2010.

How to Fix This Keyboard

Just learned from a friend, a good method of fixing thiskeyboard. Whenever some key doesn't work, take the keyboard up andhold it with one hand, and use the other hand to give the keyboard aslap with impact. WHACK! Then, the defective keys will all workagain! Seriously. She told me this, then i immediately plugged in thekeyboard, checked that x is still defective, then i whackedit, and it immediately workd! We were laughing hard about this.

This is a fantastic solution. Because this is a really great keyboard, and now you can actually make it work.

Fix by Adding a Ground

got this comment. Seems reasonable. But i've thrown-away the keyboard by now.

STOP WHACKING YOUR ELECTRONICS!!

My repost from FixYa:Well the SmApple guy put me on the right track, but the main deficiency with this keyboard is the lack of a proper ground (which would cause a static build up. Opening the keyboard, I found a bright metal screw that held the sheets to the small pcb board inside. I assumed this was a ground, but when I took that off, it wasn't connected to any sort of ground. So, I took a small wire, clamped it to the screw, and connected it to the USB (G) port. Voila, a working keyboard!

Microsoft Comfort Curve Keyboard 2000, came out in 2003.

Update:this keyboard is well-known for its key failure. See below for comment and how to fix.

Recently i bought the Microsoft Comfort Curve keyboard 2000.

This is a fantastic keyboard. If you find those split ergonomic keyboard too much, or if you prefer the laptop-style flat keys, then this is the keyboard to get.

Consider the price, it's fantastically cheap. Only $18. In comparison, most full key keyboards or ergonomic ones goes from $30 to $50.

This keyboard is very thin. About 1 cm high.

This keyboard is also extremely sturdy. One piece of solid plastic. (if you hold the sides of the keyboard and forcefully twist it, you can't bend it easily.)

This keyboard is also light weight.

Like all flat keyboards, it's basically noise-less, with quick response because of the shallow keys.

I also love the way the keys alignment are curved. It's got some ergonomic advantage of split keyboards, but kept in one piece.

In my opinion, if you judge by the ratio of performance/price, then this definitely beats all Microsoft keyboards out there, and all other keyboard that exists, period.

Right now, there are 2 other keyboards i regularly use. They are:

Judging strictly on product performance regardless of price, between the above 2, i find it to be a tie. However, i might consider this Comfort Curve 2000 even beating both. This seems impossible to believe, since the Comfort Curve is not fully split ergonomic, and i'm a ergonomic split-keyboard fan. Also, this keyboard is flat keys, which is generally considered not good for prolonged typing. However, i do find this keyboard extremely comfortable and faster to type, especially for using Emacs.

All things considered, this is absolutely a fantastic keyboard.

Update: Keys May Fail!

Just discovered this, that this keyboard's keys are prone to failure.

Comfort Curve 3000 Keyboard

I recommended this keyboard to a online friend about half a year ago. She told me she had some problem with some keys, said that she spilled drink on it. And she bought a new one, same model, and that too, keys started failing. Now she's on her 3rd one, and keys also fail.

At first i thought maybe spilling drinks on the keyboard is the problem, even though i thought minor spilling shouldn't be a problem. Unless you pour drinks onto the key, a few splash of liquid usually won't even get into the electronic parts in modern keyboards. But key failing after the 3rd keyboard??

But recently, i noticed that some keys started to fail too. The first time this happened is the F10 key. For some reason it worked the next day. But today, the Enter key wasn't working for a while, now the key x fails sometimes. It's not consistent failure. Sometimes it works perfectly, but the next minute it won't, doesn't matter how hard you press the key or how many times you press. Not single character will show.

I went to readamazon's 1-star comments.You see a lot comments about failing keys. So, this is a serious defect with this keyboard. Of all things about a keyboard, if the keys start to fail, it's the worst.
