I do the same thing, though occasionally I leave it sleeping

Ditto all above except that in addition to encountering this behavior 
with Debian 11 Xfce installed on a Toshiba Satellite L505 laptop (maybe 
twelve years old?), I first observed it on the same machine during my 
first experiences of Linux on a dual-boot installation of Linux Mint 
17.  But mostly I'd just wake up in the middle of the night to hear the 
fan running and wonder why it would need to be on, i.e. the screen would 
not light up, though with Debian 11 Xfce it seems most often that the 
screen lights up too.  Also, one of the funny things about Debian 11 
Xfce going into 'suspend' is that the computer often seems to fall into 
and be stuck in a state where the fan keeps running.  Which is a clear 
indicator that something is wrong with 'suspend' again...

I expect that Wesley Robbins 12:46 pm post to "Edit 
|/etc/default/grub| and add |mem_sleep_default=deep| to the default, 
i.e.: |GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep" 
"|may turn out to be the most productive suggestion for me to try out 
the next time I use that machine.

However, as I remain a perennial Linux naif and am also prone to enjoy 
the occasional frisson of some instance of poorly-founded or 
anti-establishment paranoia, I sometimes wonder about possibilities like 
bots, spyware, criminal hackers, the NSO Group, NSA, FBI, local police, 
crypto miners, etc.  The last time I mentioned that someone mentioned 
the possibility of a cron job. As I remember, I figured out how to check 
and it didn't pan out. Any thoughts along those lines?
