It is you who are assuming it is his laptop. Not me. I go by what is said.
Yes, PC means personal computer but typically, if a person refers to a PC in one sentence, then laptop in the next, they know the difference. And since the OP said the letters a, b, and n stopped working, but clearly were working in his post where he said he is now "usi
ng toshi
ba l
aptop" where a, b, and n appear to be working just fine, I go by my original comment and say to go by what the OP says, not what you think and assume he means - at least until he comes back and clarifies. If I am wrong, then I will say so.
As far as your other comments, they are pretty sad - a clear indication you cannot accept you might be wrong. Plus, your assumptions are irrational and unjustified.
#3 and #4 You
accuse the OP of ignoring posts when you don't know if the OP even is aware there have been replies, or if he is able to return.
#5 Your lack of writing and grammar skills does NOT imply or suggest you are more capable of assuming correctly what others mean.
#7 That's just silly. Did the OP respond to your comment? No. So by your "assumptions" he is "ignoring" you too.
# 8 Also silly. My PC (which is NOT a desktop, BTW, but a tower PC) has nothing to do with this, or my pride. I think that was a pretty puerile comment.
#9 Also silly. People come to forums like this all the time posting questions, seeking advice, then waiting for answers. That is exactly what these forums are for.
If it is just desktop keyboard, he can just walk to any PC shop to purchase new keyboard.
"IF" it is a keyboard, yes. But it is better to borrow and try another first before spending money on a new keyboard that may not be the problems. There are other reasons, besides a failing keyboard, that can cause keyboard input to fail.
You made no case.
