My laptop become slower after waking from sleep
My laptop exhibits significant performance degradation after resuming from sleep mode, with applications taking much longer to open and system responsiveness becoming sluggish compared to a fresh boot. This slowdown persists until I restart the system, and I'm trying to understand what causes this post-sleep performance drop and how to fix it permanently without having to reboot every time.

The key clue is that performance drops only after resume and returns after restart. That points to a driver, device, or background process failing to resume cleanly. Immediately after waking, open Task Manager and compare CPU, Memory, and Disk with a fresh boot; record the abnormal process or device. Install Windows updates and the laptop maker’s BIOS, chipset, graphics, storage, and network drivers. In an elevated Command Prompt, run powercfg /systempowerreport, powercfg /requests, and powercfg /lastwake. If powercfg /a shows Modern Standby, create a SleepStudy report. Test one resume with docks and USB devices disconnected, then perform a clean boot to isolate third-party services. If slowdown occurs only on battery, compare Balanced and Best performance modes briefly. Do not disable Windows security or indexing permanently; capture their activity. Use Hibernate temporarily, and give the reports to the hardware vendor if a driver or device remains degraded after every resume.
