Problem with Toshiba laptop shutting down unexpectedly
I own a Toshiba Satellite S75D-A7272 laptop. It began shutting down unpredictably, likely around October 2025. The display would turn black and shut off after a short period. After purchasing an in-house replacement battery in September 2025, I considered it might be the cause. However, it took several weeks post-installation before the first random shutdown occurred.
The shutdowns often occur within just a few seconds of powering on. It appears the system now powers off more quickly—sometimes within minutes, sometimes within hours—compared to the nearly full day it took before this happened.
Please note I’ve owned this machine since 2014 and have frequently left it running. I use it more like a desktop connected to a monitor, entering sleep mode when idle.

Welcome to the forums, newcomer!
Shutdowns can occur very quickly after turning on. It looks like the computer shuts down sooner—sometimes in just a few seconds—to several hours compared to the long waits before. This might indicate an overheating problem or a faulty power delivery system on the laptop's motherboard. Cleaning out dust and debris, using better thermal paste and pads could help. If the issue persists, a multimeter and FLIR thermal camera can identify which part of the board is overheating before it stops working.

Your laptop came with Windows 8. Based on my experience, all devices that started with Windows 7 or 8/8.1 and were later upgraded to Windows 10 tended to have overheating chipsets due to wear over time.
Given the laptop’s age, you might want to consider a desktop if you plan to use it in this way.
