How to use the ASCII code on SONY VAIO Laptop

[NavinS]

My brother has a Sony VAIO, and it is impossible to type ASCII codes on it. On my PC I am able to press ALT plus the code and it works well but on his laptop it is impossible. If among the friends of the forum someone uses the Sony VAIO I am interested in your trick.
Thank you in advance

I can't speak for all makes of laptops but on my Sony Vaio, numeric lock needs to be enabled for the ascii codes to be entered on the numeric keypad, which are otherwise just normal letters on the keyboard.
Does that help at all?

p.s. the numbers are sometimes written on the side of the key or in small near the letters, usually on the right side of the keyboard.
