Laptop won’t reboot after initial use following battery replacement
텍스트:
Last night I replaced the battery with the iFixit kit. Everything seemed to go as expected until halfway through the battery calibration process.
After completing the replacement procedure I left the laptop on charge overnight. By 4 am the power indicator had switched from red to green and around 8 am when I unplugged the laptop and opened the lid, they keyboard backlight was illuminated but the screen was dark. When I pressed and held the power button I heard the computer shut off. Then, when I powered it up everything booted fine and the battery indicator showed that it was at 100%.
I then connected the laptop to a self powered external drive (4Tb USB3 G-RAID) and ran an encode in Adobe Media Encoder in an effort to speed up the battery drain (per battery calibration procedure to allow the battery to fully discharge).
When I came back an hour later to check on the computer I discovered that it had shut off. I attempted to reboot it but the progress bar only made it to about 40% before shutting off again. I tried this repeatedly with the same result.
Then I reset the SMC (Ctrl+Opt+Shift+Power for 10 seconds) with no change in result.
According to the battery calibration steps, I am supposed to let the battery drain all the way until the computer goes to sleep, then leave it asleep for five hours before charging it. But the computer didn’t go to sleep so I don’t know what the next step should be. Advice?
