Hi,
For the second time in about a week, my laptop starts with the keyboard and mouse unresponsive. The laptop boots normally and everything looks ok, except that I cannot do anything with the mouse and keyboard... I tried to plug in external usb keyboard and mouse and they work properly (meaning that I can move the pointer and type in letters). Last time I solved it by resetting the PRAM (cmd+alt+p+r, see my previous post just above), but this time I had to restart it at least 5 times before it worked (the 4 first times it booted normally without repeating the startup sound as if the keyboard was not responding even before MacOS is launched). Now it works fine, but as it seems to get worse, I don't know if I'll be able to solve it next time. Any suggestion?
Could it have anything to do with cold temperature? I noticed that it happens essentially when the laptop is very cold (I come to work by bike and it's freezing outside in the morning where I currently stay).
