Windows 7: After waking from sleep mode my keyboard letters are messed up.

When I wake my PC from sleep mode some of the letter keys of my keyboard are changed with numbers. Only restarting PC helps. I noticed this problem some days ago, but before then there was everything OK. I changed key sequence from control panel - text services and input languages - switch keyboard layout to not assigned but the problem is still here. Any sollutions?



My Pc config:
Windows 7 ultimate 6.1.7601 (Windows 7 RTM), MB: Asus P5Bv, Intel Core 2 Duo E4500 2.20Ghz, Ram: 2GB

What do you mean that keyboard has numbers do you mean when type something if so it sounds like the filter key this happen when you hold shift too long when your are word or any other office key try and turn your filter key off

To turn the filter off
Go start>control panel
Click on Ease of access
Click on Make it easier to use keyboard
Uncheck toggle on filter key

Maybe the num lock is on.

That could be one possibility

It was the "NumLock" causing this problem.. Thanks for solution

Good deal. Glad you got it straightened out.

Hello, I got same problem with my desktop PC:

MB: ASROCK H61M / U3S3
Intel G620 2.60GHz
Genius USB Keyboard KB-110
Windows 7 Ultimate x64

History:
1. Turn on PC --> keyboard works normally
NumLock LED: on

2. No activity, PC go to sleep mode.
Press keyboard or mouse button to wake up PC, NumLock LED still on
---> these characters change:
m -> 0
j -> 1
k -> 2
l -> 3
etc

I think it likes laptop keyboard, but this is desktop not laptop.

Solution?
Here I have done:

1. Turn off NumLock (LED becomes off). Yes, it will makes m, j, k, l, etc become normall again but Numerical keys on right side will not work .

2. Restart PC.

3. Unplug USB keyboard then plug again.

4. Change keyboard to PS2 model.

Last one is what I did right now. It seems solved, but still curious what's the real problem.
