New keyboard...like a charm
My daughter has been using her old college MacBook Pro (2008 model). However during her old good college days she spilled a glass of milk over the machine. Surprisingly the machine was fine, but not the keyboard. MacBook Pro could have been operated with an external keyboard but there were some stuck keys preventing it going to sleep.
We got the keyboard and the spudger and using the on-line instructions we dived into the repair. As we already knew how to open the MacBook Pro, this was a breeze. Replacement went smoothly with some slight delays with the ribbon cables, I was not sure that they fit precisely the way they should. But after we were done, everything worked as it supposed to. The whole experience was shorter than one hour disassembling, replacing and assembling back again.
Read and watch the online manual first. Then go for it but have another computer with the manual open in your working area so you can refer back and forth. Next, get a magnifying glass and good lighting. Some pieces are really tiny for the naked eye.
