So here is what happened... One day I was using the laptop for animating and such, I felt tired so I went to the bed.. When I had to go to the toilet I came back to use the laptop 15 or so minutes later BOOM it shut off. I got so scared and I immediately booted it back up not only 5 mins later the laptop shuts down. I tried doing an electrical discharge thinking it might be something with the battery ( it doesn't hold charge)

I need help urgent as I have a list full of customers to attend to
.specs and details will be defined if. Needed

I do not want to open the laptop on. Fear of making it worse

This thread highlights two common root causes for sudden laptop shutdowns: software/power-profile behavior and thermal/airflow failure. correctly called out power-plan settings as a quick, noninvasive check, and ’s follow-up shows airflow problems are a frequent physical cause. The guidance below expands those points with safe, practical diagnostic steps and long-term precautions.

  1. Isolate the power source: run the machine on AC only (remove a user-removable battery if possible) to see whether the problem follows the battery or only appears on battery power.
  2. Check Windows logs: examine Event Viewer -> Windows Logs -> System for entries at shutdown times (e.g., Kernel-Power / Event ID 41 or thermal/ACPI warnings) to distinguish abrupt power loss from controlled shutdowns.
  3. Monitor temperatures: use a hardware-monitoring tool to log CPU/GPU temps under idle and load. Repeated spikes into the high 80s/90s C that precede shutdown point to overheating.
  4. Safer cleaning steps (noninvasive): blow dust out of vents with short bursts of canned/compressed air from outside the chassis, hold fan blades still to avoid overspinning, and keep bursts brief. Avoid using a household hair dryer on high heat—hot airflow can soften adhesives and push dust deeper. If under warranty, avoid opening the case.
  5. If airflow cleaning does not stop shutdowns: check BIOS/UEFI for fan diagnostics, update BIOS and chipset drivers, and consider fan replacement or professional service. A battery that no longer holds charge is a separate reliability issue and should be tested or replaced.

Preventive notes: schedule periodic vent cleaning, avoid operating on soft surfaces, and consider a cooling pad if workloads are sustained. If uncertainty remains after these checks, a service shop can safely open the unit, replace failing fans or thermal paste, and verify whether the battery or power adapter needs replacement.

Look at your power profile. It is likely that the system is set to turn off or hibernate if the lid is closed, or there is no input, for some period of time. These parameters can be adjusted, so when you are plugged into wall power it won't shut off, sleep, or hibernate.

Its OK it turns out the fan wasn't able to work cause there was dust in it.. I used a blow dryer and fixed it instantly. Thanks for helping though
