the only way I can resume it is by force shutdown & reboot again. This usually happens when it is running in battery regardless of charge (it occured when battery is around 70% as well as 35%) & mostly seems to happen when CPU or RAM usage goes high. Laptop is Lenovo IdeaPad 320 series with Intel i5 7th gen, AMD Radeon graphics 530 4 GB, 12 GB RAM.
Go offline, do a DDU on both Intel and AMD GPUs, reboot and install latest drivers manually.
1. Repair Windows by running 'sfc /scannow' (Run as Administrator).
2. Use Resource Manager to check if CPU/RAM usage is not at full capacity.
3. Run Malwarebytes and antivirus scanner.
4. Check disk and ram health.
5. Start your laptop in safe mode.
actually i also have same problem running win 10 on battery it gets bsod but when plugged in nothing happens all good
Check Event Viewer for any meaningful messages next time it happens. Even if you need a hard break, Windows might have recorded system/application events in case any driver is crashing or any other cause.
