My Acer Keyboard wont respond when i press the key's

A few days ago my acer laptop aspire 1640z , began to behave slower than usual when typing on the keyboard. At first I thought it was a virus, I did all the necessary scans and found none.
I then thought it might be the Keyboard driver, but it wasn’t.
I went into safe mode by keeping F8 down when you start the computer and select the directory service restore mode, which resets certain applications back to its original state. I found that my internet AOL connection and explore and fire fox would not connect to the net. Make sure you have a disk for AOL or setup file for fire fox saved, to reinstall the software. This seemed to work a bit but by accident, I remove the battery from my laptop and kept the power cord connect and Wow! it works even faster than before.
I have also notice that my battery does not hold a charge anymore. My theory is that because the battery is in critical status when connected to laptop…. (Even though the power cord is connected), the computer thinks that its going to run out of power and wants to go into hibernation mode which slows everything down including typing on the keyboard.
So before you try the safe mode option, remove the battery and use only the power cord cable and see if this solves the problem. Mine is running fine again ,but when I put battery back it slows down again. I read on the net its affecting only Acer Laptops, probably because the way the power settings software is set up for the Acers.
