No sign of life at all. No response to pressing the power button. No chime. Blank screen. No lights. No sounds of hard drive spinning. Would cold temperatures cause power supply failure? LeRoy On Thu, 2023-06-08 at 17:14 -0600, Jeff Free wrote:

Does it do the Mac chime?

No implies the power supply.

Yes means it could be all kinds of things. 

Next is do you see anything on the screen?

Send more deets, if you want.

When In doubt; frolic!

 Hi NMGLUG folks,

A friend has a 2015 Macbook Air that won't turn on. He used it for months while it was exposed overnight to below freezing temperatures. One day, it wouldn't turn on, and has not been able to be turned on since then. Any ideas?

In gratitude, LeRoy
