1st thing 1st, start backing up your files. ASAP.
(hard disk problem being reported is very very bad for hybrid ssd/SSD, as u may not boot into the hhd ever)

then u can start the diagnostics below.

try shutting down and booting up without battery inserted.
if things are normal, then your battery failure; just replace.

if u boot up and get  any error such as memdump or temp related,
and the battery removal did not work,
time to change to full SSD perhaps.
truth be told, 24GB cache is not a lot and who know if it's mlc or slc type or worse tlc type.
if TLC then i guess the error is prone to come very soon.
If you download a lot of ' 'content' ' for the last 2 years, then this is highly likely the case.
i suggest getting a 250gb ssd or at least 500gb ssd if so.

I would say the hybrid ssd is most likely the cause as when shutting down, the memory cannot dump and keeps trying hence not shutting down. moreover, u forcing it to shut could cause some corruption within the drive system files. so more and more error will prompt up.

If changing hhd/ssd did not work, then it could be bios update needed.
maybe some update u recently got can't match the current bios.
proceed with caution as flashing wrong bios will rekt ur motherboard and your whole laptop.

correct me if i'm wrong.
i did all this research long when i was choosing hybrid and ssd.
SSD sill best esp MLC/slc hardware.
newer hybrid is much better than your older hybrids.
