Screenshot of Why My Asus Laptop Kept Rebooting After Sleep and How to Fix It

A user with an Asus Zenbook Pro 17 describes repeated restarts after closing the lid: instead of resuming, the machine rebooted as if it had powered off, losing open work and sometimes returning warm and nearly drained. Investigation with Windows Event Viewer showed the problem tied to the MediaTek Wi‑Fi 6E MT7922 driver (mtkwlex). During Windows Modern Standby the OS tried to disconnect the adapter, but the driver failed the low‑power transition and logged Event ID 1033 referencing \Device\NDMP3; a missing/corrupted driver message resource produced a generic warning. Because the adapter stayed in a bad kernel state it caused abnormal battery drain and heat, triggering Event 507 ("AUSTERITY BATTERY DRAIN BUDGET EXCEEDED"), which forces a wake to avoid full discharge; the forced wake combined with the crashed driver led to silent crashes or thermal shutdowns and subsequent reboot (Event 12).

The practical fix is simple and immediate: in Device Manager expand Network Adapters, open the MediaTek device Properties → Advanced tab, select the POWER SAVING property and set its Value to DISABLED. Preventing the adapter from entering its power‑saving sleep stops the driver crash sequence. A proper MT7922 driver would be ideal, but none was found; after applying this workaround the laptop ran reliably for three weeks.
