If you're using your best laptop for entertainment purposes, sleep mode is not a good idea because the download will pause when it enters this state. Another drawback is that any interruption in the power supply or network connection may render the file unusable if downloading large files such as media content which can take an extremely long time to download and interruptions are more likely during this process. However, there are benefits of installing updates while your computer sleeps - especially important security patches! It's still advisable to install these updates manually when possible and avoid leaving your system idle too often so downloads continue without stopping with sleep mode enabled.
