My ThinkPad P50 has been having some difficulty shutting down lately. Any time I shut down or restart, after the usual Windows shutdown process, the following happens:
- The screen turns off completely (backlight included);
- The Num Lock and Caps Lock LEDs, as well as the power LED turn off;
- The audio mute LED remains on.
This can last just one or two seconds on the short end, but I’ve had it last over five minutes, at which point I killed it using the power button.
Additional info:
- Windows is installed on an M.2 drive;
- There is a SATA drive with a Debian installation on it (I believe the start of my issues more or less coincides with this drive’s installation, but it’s been to long to remember if it matches exactly);
- The Windows drive is BitLocker encrypted;
- Secure boot is off;
- Windows Boot Manager has been exchanged for GRUB;
- Linux experiences no such issues.
As nowadays I often switch between the two operating systems, this can get seriously annoying. Thank you in advance for the assistance.
