ok my sister just told me that she spilled a mudslide drink on her key board and her 'E' and 'R' keys both dont work. since it is a laptop is there anything she can do get it unstuck. she dint purchase a warranty with it. and she said the #2 key fell off and she cant get it back on. so she doesnt want to take off the E and R key. but does she just have to by a key board that connect to the laptop and use it like that or is there something she can do?
