Hi, I have a Macbook Air from mid 2011 and, some time ago, the qwerty row works only occasionally , if I apply loads of pressure on the or W keys. I’ve been through the forum and tried some suggestions. 1-I’ve checked the battery. It is not swollen but it needs to be replaced, since it only works for 20 minutes or so. 2-Removed the battery entirely and tried without battery. 3 - Looked for bread crumbs, etc 4-Did a diagnostic and everything seems to be normal. Nothing of the above worked.. Can you, please, throw some light on this? Best regards, Pedro
Your keyboard works on a grid system a bunch of columns & rows of lines the key shorts across them to tell the logic what key you want. So clearly the keyboard row line is stuck! Likely liquid damage or a crumb is messing it up. There is two ways to fix this the easy way but a bit more expense or a cheaper way but way harder! Lets focus on the easy path! Here’s the needed part MacBook Air 13" (Mid 2011) Upper Case with Keyboard iFixit has a used Grade-B part which gets you a new keyboard and here’s the guide to put it in MacBook Air 13" Mid 2011 Upper Case Replacement basically you are transferring the other parts to this uppercase. For the hard way you’ll need to follow the same guide, here you replace the keyboard alone MacBook Air 13" (Mid 2011-Early 2015) Keyboard Its a bear to do so be for warned! $60 vs $30 for the parts but its a lot more work for the cheaper!
