Hello
When sleeping while connected to power my laptop stays really warm, almost hot to the touch.
The power button led is off when it's sleeping, so I don't think there is something that is blocking it from actually going in to the sleep state.
Is there a way that I can troubleshoot this to better understand what is going on?

Sorry, not aware of any troubleshooting options.
With Win10, turning off a laptop does not actually shut it down. I sounds like it is hibernating and that will use power.
Win10 has enabled a new hibernation process known as Fast Startup -- which is enabled BY DEFAULT. This is different from Fast Boot, which is a BIOS/UEFI option.
Fast Startup is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. It's also a new form of hibernation known as hybrid sleep -- and this causes battery drain to maintain the state of the PC while turned off. In some rare cases, it can also cause a laptop to overheat because the processor is still running and still generating heat, as this has been reported when the laptop was turned off and put inside a case.
Disabling Fast Startup might fix booting and shutdown problems.
There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.
Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup
Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F
In both cases, reboot Windows.
NOW, Fast Startup is disabled.
See if that helps.

Hello,
Thanks for the suggestion, but I am afraid that it did not work.
Fast Startup is disabled at the moment, but my laptop keeps on eating through battery and staying warm when sleeping. I have reverted to shutting my machine down every evening, which is very inconvenient.
I forgot to mention, I am running a beta build of Windows 11, through the MS Insiders track. Not sure if that makes a difference, I think I've been experiencing this issue since before going to 11.
