macbook air 820-0165-a long boot and no wake up


New member
hello everyone,
I have a macbook air 820-0165-a which take a long time to boot (2min).
Its hard to prompt to boot.
When the mac finally boot up it work perfectly no lags.
The other issue is when you close the mac and open it to leave sleep mode, wake up fail and reboot the mac.
Any idea ?
