My work (not Google) get compelled reboots sometimes for patches. We're able to delay them suitably long enough, so most of the time you just go ahead and shut down at the end of the day. Either that, or you hit reboot at lunch. Everything worthwhile is running in a VNC anyway, so you just reconnect to your VNC after your laptop boots back up.

Uptime on the VNCs lasts as long as physically possible (e.g., a full IT shutdown, or hardware failure on the machine)
