Hello There,
I upgraded it to windows 10 and then did clean install. And according to dell driver update recommendation, i updated its bios to latest version. (but it didn't get updated and still showing the last version).
After then i started facing this problem. After long run (more than 3hrs), when i shutdown my laptop (from start meny> power> shut down).. screen get black/off... working light get off but when i Keyboard backlit.. it is still ON.
and it didn't get completely Shutdown, until i press Power button for a long time.
Later, flashed Bios to same version (which came with laptop, and didnt get update above) to be sure..there is no conflict...
but the Shutdown, problem is still there...
Infact, i downloaded Windows 10 ISO from windows site.. and performed a proper Clean Install with formatting the OS drive..
but still facing the Shutdown problem..
please provide some suggestion, if anybody have the same issue.
Thanks for your help in advance.
