OK. A friend of mine complained to me that his lenovo g500 had stopped working correctly - he couldn't log in. I had a look at it and for some reason the run carriage was not responding. A bit of jiggery and I managed to at least log into is home screen. But then I noticed that certain other keys weren't working - essentially the nearly the entire z - m row as well as @ and run and enter keys on the keyboard. I tried various options in attempting to bring them back to life but nada.
So then this morning I get a message from him panicking as he has received an email claiming to have video dirt on him. Now, I haven't seen the email yet. Later I'll post it here, but he says it mentions something about them disabling functionality. As I say, I haven't seen the text yet, but is it possible that whoever this is really has managed to disable his keyboard somehow?
I'll be back soon with that text in full. Any suggestions as always TIA.
