Recently I was typing away using Notepad and noticed that some keys were dead. That is if I pressed them the cursor showed no response and the character would not be typed on the screen. On further investiggation I found the following keys are dead r, u, y, 2, 4, 0 and * .
I have checked for viruses and malware and the laptop appears to be clean. There is no sign of any damage or knocks to the laptop. The laptop has its own desk space. I have typed the keys in other software in MS Office and also tried logging in my yahoo eamil account. The keys are dead. However I can copy and paste the letters and numbers from other texts and documents and that seems to work. I regularly clean the registry and rolled back to few days ago when I knew these keys were definitely working and rebooted. But the keys are still dead. Short of opening the the laptop is there anything esle I can do to. I strongly suspect this is asoftware problem since I cannot see how the laptop could have been physically damaged.
Is there a way I can check how the laptop maps the keyboard which sounds to me like a good start and hopefully be able to correctly remap the dead keys.
I would be greatful for any comments and suggestions.
By the way I am typing from my pc at work.
The laptop is a 4 year old Sony Vaio 512Mb RAM, 80Gb HD WinXP Pro it is generally used for browsing and MS Office, no games.
