Hi everyone
After after upgrading my laptop to windows 10 , I found a small blank white window at left side when it woke up from sleep.It last till restart.
No idea, but......
After such an upgrade you will likely need to check with the computer (laptop) manufacturer's support website and download and install driver packages for your hardware devices, paying particular attention to BIOS, Chipset, Storage Controllers, Audio, Network, Video, etc.
