Recently I upgraded my inspiron 3537 to windows 10, and since then I have been facing nightmares. My laptop stared shutting down randomly initially, and finally stopped Turing on altogether. Some how I turned it on and entered safe mode, ran dell diagnostics and everything turned out to be fine. Then I ran  online dell diagnosis and found my bios driver were out to date, so I decided to upgrade them. While installation my system automatically turned off and now I am unable to turn it on. I tired taking out battery and pressing power button to drain battery and then put my laptop on direct AC, but even that is not working. My power led blinks for a second and then poff. Nothing happens. Plz help...
