<div dir="ltr">I have a Dell Inspiron 6400 laptop running Fedora 8.<br>When I shut the lid, the screen is blanked _and_ the<br>backlight is turned off.<br><br>(I think the same thing might be happening when the screensaver<br>
kicks in and blanks the screen and power management kicks in<br>to turn it off..but I can't confirm the later).<br><br>But then ~5 seconds later, the backlight is apparently turned back on<br>(behind a black screen) So the florescent tube is always<br>
running, and therefore aging.<br><br>Can anyone shed light (pun intended) on this scenario,<br>and where to look, and how to fix it.<br><br>I tested my hypothesis, by shutting the lid and looking at the glow. <br>hen ssh'ing in, and running 'vbetool dpms off'.<br>
and it actually turn the light off, and kept it off.<br>...same for 'standby' and 'suspend' options.<br><br>TIA<br>Fulko<br><br></div>
