Mac Air late 2010 does not turn on
Power Adaptor is connected, charging is normal (orange light is lighted on the adaptor connector).
No signs of life and no welcome chime after I press Power button, except for the cooling fan turning on after a minute.
PRAM reset (Command-Option_P-R keys pressed) and SMC reset (Shift-Option-Command-Power on buttons depressed then released) have not helped.
Any other ideas, guys?
Is this a good question?
