Welcome to AskUbuntu. There is not enough information here to offer any specific suggestions. Have you checked the system logs, `/var/log/syslog` specifically, to see if there are any messages explaining why the machine will not wake? Is your hardware too new for Ubuntu 18.04? Have you tried newer versions of Ubuntu, such as 22.04?

Suspend and hibernate might be started by the system but if your hardware does not react on anything that should wake the system up you would need a BIOS upgrade to fix this.

Either use a newer version (I see no reason to use 18(.04)) as it might be fixed in newer kernels or disable suspend and/or hibernate if one of these does not work and you can only use dim the screen.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
