still fan running fast but this time dim display backlight no display or logo and restart after 10-15 seconds. and once it showed some sold colors white green blue red and restarted. and forget to mention that after previous patched bios file i manually did the bios updated from official dell website to check if my nvm detection fix or not. but it was not fixed . after writing the backup dump all this happened.so help please. also tell how i should first boot . like on battery without battery etc.thanks

here same procedure. remove cmos and battery before and after flashing. just use the charger in first boot. if everything is okay you can put back cmos and battery.
