Keyboard problem Im trying to transfer my info from my ibook to my new Desktop and as i have spilt some liquid on the laptop some of the functions arent working ,so to try and transfer my info i need to enter my password and the letter 'A' key doesnt work and my password has 2 A letters !! how do i solve this situation ,would another external keyboard be the answer?

The easiest fix is to go to Edit>Special Characters, find the "a" symbol under "Latin", and insert it wherever you need one.

In the short term, you could attach an external keyboard and solve your problem. In the long term, it is risky to continue to use a laptop into which liquid has been spilled without having it professionally cleaned. Contaminants such as soft drink sugar or coffee solids can dry on critical components and eventually burn them out, requiring expensive logic board replacements. If you are going to discard your old iBook this may not be an issue to you, but if you would like it to retain its value, a cleaning is in order.
Additionally, if you use the Migration Assistant in your new desktop to transfer the files from your old iBook, you will not need to type anything on your old iBook, and the migration will be complete and automatic. Launch the Migration Assistant on your new machine and follow the instructions.
