Hi guys.
I've come across this laptop which randomly turns off after like 5-6 mins of usage.
When it turns off, I have to wait a bit for it to turn on again, if I don't wait, the blue light turns on and immediately off.
I've thought of a battery issue, but the laptop does this even with the battery disconnected.
The temperatures are not at fault.
I don't really know what to do.

Also, when it finally turns on, the laptop is veeeeery slow to boot up, with a known good ssd which boots up in 5 secs in other laptops.

When the laptop is actually on, it's very fast, runs cold, no weird noises.
