Hi, i have a noteboook hp pavilion dv7 2050 es, the last week I shutdown my computer and when I on the notebook, only appear and black screen. the battery of the bios fell. Not appear the menu of the bios, even pressing esc. f2 or f10. I tried connect another external sreen but was black too. There is not signal of leds in the keyboard, only when I start the computer they light on once time and no more. I do not have the partition of recovery or the hp_tools. I try to use the hp pc hardware diagnostics 3 in 1 usb key, also put the bios in a usb or in cd (f.42 and f.33) but anything function.
Why i can do in order to re-install de bios?

Try a hard reset.Disconnect all external devices first.
1-remove power cord and battery
2-press power button for 30 seconds
3-reinstall only power cord for first startup.
4-try power on
