Black screen, fan/harddrive working, no capslock blinking

[sachinhole]

Hello, I am using hp 15s du900tu laptop. I updated it's bios through hp assistant. But after update it doesn't turn on. But power led is on and harddrive is also working, fan also working (i can hear a sound) but display is blank. There is no power in display. And tried to recover bios but it doesn't show bios recovery screen.
