Very stranged case. This macbook pro comes to me because sometimes when power on the macbook it goes to boot menu and in OS X appears simbols that normaly appears when press ALT+some key.
Keyboard was durty and I thought it is keyboard issue and I repalced the keyboard. Tested and work ok, but next day customers come again and I can see now that problems appear again. If it is not keyboard problem, what more could be?
