Aspire M5-481PT keyboard malfunctioning

abone114 — Sun, 25 Aug 2013 00:36:01 GMT

Hello, I've searched this board all over to find someone else with the same problem I'm having but I was unable to. Randomly, certain keys on my keyboard stop working. Namely the Q, T, U, P, J, 1, 3, _ and the left arrow key. I've tried a few things to try and fix this. First I tried uninstalling the keyboard drivers and restarting the computer which does fix the problem SOMETIMES but this is sporatic and the next time I boot up there is a good possibility the problem will return. The next thing I tried was going onto the 'Ease of Access menu and checking on 'Filter Keys' clicking apply then I uncheck 'Filter Keys' and again click apply. This also fixes the problem but this too is sporatic and does not last. The only other thing I can think of is trying to reset the laptop to factory settings (extremely annoying). What is the problem here? This is a manufacturer refurbished laptop and I bought on March 4th, 2013. Would this issue be covered under warranty? Any help would be necessary, I'm a writer so this problem is affecting me greatly. Thanks!

Please do not try to speak for the entire Acer customer base!

I have this same while I'm trying to type this message. MANY others have it too if you Google search it. Many, for me, its Acer's spacebar (middle and left side only malfunction).

Selecting [Fn + NumLk] fixes the malfunctioning A-Z letter keys in my case.

However, I'm still experiencing issues with the Arrow keys and the top row Function keys (F1, F2, ... F12).

In addition, upper-casing an [A] character requires the use of the [left shift] key, it does not work when the [right shift] key is activated.

As per the above posting, I'm continuing to search for a more complete, long-term resolution to the problem.

Hi everyone,

I have the same issue as well with two kinds of Acer M5 in France and with a French keyboard for a year. Both of them are in Windows 8.1 x64 with the 128SSD.

I first used the warranty to get the issue fixed, but the guys have never figured it out and got me a new M5. I got the issue again 6 months later and I am tired of professionals not being able to get this fixed. This is ridiculous.

Then I did the work myself. Although I unmount the keyboard several times by opening the laptop, the issue still remains. I have noticed that the issue comes back more often if I travel a lot with my laptop.

I am now trying to run different kinds of drivers, new and old versions hoping to get something that runs properly. I am surprised that Acer doesn't do anythink for this issue, knowing that it seems extremely common and that the laptop is quite expensive (700 euros on sales in France in July 2013).

Anyone has tried to install windows 7 instead ?

Let me know if anyone has found a solution.

Hi Everybody,

So I found the fix that worked for me.

I hope it will work for all of you who are or have been looking for the fix to this most annoying problem.

It deals with erasing certain values in your registry which is explained in a number of easy to follow screenshots at this website.

It worked like a charm for me.

Good luck!

Cheers

Hi,

I tried the above solution, deleting registry values. All it did was not recognizing my keyboard anymore (or any USB keyboard connect to the PC). I had to put the registry key back to recover a functioning keyboard. The original issue still remains though. I have been missing on and off the follwing keys: "Tab, 1, ², escape and caplock."

I am still looking for reliable options. I have installed Windows 7 and it seem to work. However I have not been using it long enough to know if it is a lucky fix or a steady improvement.

Best.
