My old laptop died - a tiny little pop and it powered off. So I've lost my implementation reference. My new laptop is a Lenovo v15 G3 - installing debian-12.5.0-amd64-netinst.iso from a flash drive was trivially easy. Whoever worked on the how to install Debian from flash did an excellent job. But I can't suspend or hibernate the laptop :( Both options are greyed out. How do I enable suspend / hibernate? TIA, Lee
