Mac laptop keys are not showing letters but symbols and delete key not working. How do I unlock this problem?
There could be a couple of possibilities :-
1. Faulty keypad
2. IC on the main board
Faulty keyboard is more often a problem. Even though there is no dust and dirt, faulty keyboard may result in all the above said symptoms.If you press a letter key, a symbol might be there. If you press delete key, it might not work. The best option what i follow in my shop is replacement of keyboard. There are certain days when i only replace few keys, but more often if this is a problem with more than 5 keys or with all the keys on the notebook, better to go for a new keyboard.For your laptop, always prefer hard keys as those are more durable than the soft keys.
IC on the notebook is again one of the reasons. This is usually a problem with old laptops, such as 5 to 7 years old. New laptops generally do not have this problem. If laptop IC is at fault, soldering is required to get it fixed.It needs a tech to confirm the faulty IC on the mainboard and then followed by replacement.
Let me know,if needed further assistance.
Hope i helped you.
