[nmglug] Any ideas to revive a 2015 Macbook Air?

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 -- There is something glorious birthing within all of us. I am the Love of God, no matter what.BSA LeRoy Diener 213-LEROYIZ 213-537-6949 https://leroydiener.com
