Nx7010 does not start.

Hello dear, probably some BIOS values changed, causing u no displays. Try this key combination immediately after startup

esc - loads bios, but not in display
F9 - (hope its F9 in ur laptop) resets BIOS
F10 - saves BIOS to default values and exits
RESTART

Or else try removing CMOS battery, its right beneath the keyboard. (Just remove 1 screw) Remove and hold for 1 minute and then reinsert and turn up laptop on. Your PC should be fine.
