Nhấn phím Caps Lock lần nữa. Vệ sinh phím bị kẹt Khởi động lại máy tính.

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
If you turned on Caps Lock by pressing the Caps Lock key (accidentally or otherwise), pressing it a second time will turn off Caps Lock if the key itself is functioning properly. This can be annoying given Caps Lock's proximity to the ⇧ Shift and Tab ↹ keys, so you may want to disable it entirely. This is possible on Windows and Mac computers. . If the Caps Lock button doesn't turn off when you press it a second time, it might be stuck in a lowered position. Clean it with a can of compressed air
