Question about Acer Aspire 4720 Notebook
You can try to GENTLY pop/pry off the keys that do not work, and see if the rubber membrane, (it acts as the spring, when you press a key) is still there and in place, with power off and battery removed, try a q-tip with a LITTLE rubbing alcohol, and clean the area under the keys, replace the membrane, and pop the key back on and test. before I would buy a replacement keyboard, you may want to restore the PC to the factory settings,(ReInstall Windows, etc), and make sure its not a software/windows problem or if its a hardware/keyboard failure. if this helps please give a fixya rating thank you

Examine your keyboard to ensure your "Number Lock" key is not activated.
This activation is indicated by the key being lit up.
If the key is activated, press it to deactivate the lock.
The number lock key will deactivate an entire segment of your keyboard
Start, click Run, and type regedit to open the Windows registry editor.
In the registry, open the below folders.
Within the keyboard folder, you should have a string value named "InitialKeyboardIndicators" with a value of 0, 1, or 2. Below is the explanation of each of these values.
0 = Num Lock is turned OFF after the logon.
1 = Disable Num Lock.
2 = Numlock is turned ON after the logon.
hope this helps
