Machine works fine, but when it sleeps, it does not wake up, keyboard backlight comes on, screen does not come on at all, SMC reset and P-RAM reset has been done severally, nothing changed
at first the system wasn't completely booting, so i change the SSD, its now completely booting, so i now got this screen not wakening up after sleep, so in a nut shell i just installed bigsur on the ssd, still not waking up installed i now tried another known good ssd from another system, it will load to 100% progress bar but it wont switch to desktop or home screen, its will stock on 100% progress bar for ever
Usb Catalina macOS wount boot pass the progress bar it will be stucked on 99% progress bar forever.
but BigSur and Monterey will boot to recovery.
Then I notice it takes longer time for it to chime.
On Monterey, when it sleeps and I opens the lid, they keyboard light comes up immediately and the display flashes and after 3 seconds screen will now stay.
Then sometime the screen backlight only will come up for like 5 seconds before the display comes on.
