Keys seems to be permanently pressed not even able to enter password
I have wireless keyboard for iMac. It suddenly stopped working properly. When I enter password, it would not work. When I press power button, it will start working randomly and keep on entering some alphabets / numbers automatically. I ALS tried to enter password as soon as I turn it on, but it would not work. Looks like only some of the keys are working automatically.
Please help me what could be problem and solution, if you can suggest.
Is this a good question?
