My laptop in an Acer Aspire 4738. Some of its keyboard doesn’t work.
When I connect an external USB keyboard, its “shift” key changes to backspace. At first, I thought it was a corruption in my Windows 7, so I reinstalled it using Linux, but it still didn’t work. Because of frustration, I changed it again into Windows 7.
I am so stressed. Please help me! Thank you in advance for your answer and help!
