Your operating system is not starting, put the cd that came with unit in the drive and boot the laptop to reinstall the system.

SOURCE: It's not working!

It seems to be a software failure. Try using your recovery CD to sort it out. If it continuous then i would recommend a clean install if there's nothing that important on your laptop.

SOURCE: I turn on my PC

The onboard video could have died. Plug in an external monitor and see if you get a display.

Why a black screen on xps l701x w7 i7 1.73


Black screen - no flashing white cursor in the upper left corner - no picture at all, i.e. the initial Dell start-up screen doesn't show up either:
- LCD is dead or isn't getting a signal - not an easy fix; or
- the LCD isn't being sent a signal - holding down the function [Fn] key and press display Function key to toggle through its settings (LCD panel only, Rear VGA output only, both LCD and VGA output)

Black screen - flashing white cursor in the upper left corner - the screen goes black after the windows loading screens come up but before the windows login screen comes up - it is probably a windows video driver problem. Try starting in Windows Safe Mode with VGA. Press [F8] after the Dell startup screen disappears to access the windows startup menu

Some 235s had a problem with the contrast setting. When the contrast is set to full the screen turns black.

When you turn on the GPS and the screen goes black, try tapping the left arrow on the track pad a few times. You should see the screen start to lighten. If that doesn't work, tap the power key and try tapping the left arrow a few times.
