Hello, please help me. I am using an Acer notebook and suddenly, when i wanted to type something the letters 'u, i, o, p, j, k, l, m' became numbers and symbols. i realised that on the key, there was a blue number / symbol that, on a normal keyboard, would type those numbers/symbols if you press the 'fn' key. So, the only way that i can type the proper letters, is if i hold on to the 'fn' key and type, which is what i am doing right now. HELP!!
