laptop backlight?
Discussion
Can anyone help?
my cousin asked me to look at her laptop and the problem with it is that after a couple of minutes use the backlight switches off for no apparent reason and stays off till the machine is restarted. am i looking at a new CCFL inverter? or is there something simple ive missed?

hi stefan,
you still got your marlin?
the laptop in question is a toshiba satellite 1110 (catchy name eh?) and yeah, my understanding was that there is a cold cathode tube behind the screen that illuminates it from behind. because the light works to begin with, i assume the tube itself is ok, but because only a restart will get it back, im assuming its not just a power saving setting to be changed. having said that - is there anything obvious i should be looking for?

yep lcd have a light behind. never heard of one working then switching off and not coming back on - bit odd that. I would be looking very carefuly at both hardware (bios) and windows based power saving features before supecting hardware. I seem to remember tosh usually have their own power saving software installed.
Well I never knew that. I though it was the screen glowing rather than a bulb behind. I seem to remember loading power-saving software on the old Toshiba's I was fixing a few years back...
Yep, still got the Marlin, lots breaking and getting fixed but I hit PistonFest in it (it was on PR Photography tour stand and Muncher took a picture of it
). have a look on <a href="http://www.stefancarlton.net">www.stefancarlton.net</a> for details (been updating it recently)

This is done through the power management settings, which are accessible through the Control Panel or via the 'light bulb' icon in the Icon tray at the bottom right of the screen. The user can adjust the screen brightness both in the mains-powered condition, and at different stages of the battery life - so that, for example, the screen can be maximum brightness when the system has 100% battery power left, and dimmed as the battery reaches 75%, 50% or 25% of the full charge. The three levels of screen brightness are 'Super' 'Bright' and 'Semi'.

cheers guys - ive had a good old look at it and suspect that the wierdness of the problem may well be due to the uniqueness of the situation. my cousin stored the machine for about 4-5-6 months under her bed in which time the battery wasnt monitored or anything. when she first came to use it was where the troubles started and i bet the battery is feeling a bit wierd at coming out of hibernation and misreporting its output levels, so causing this problem.
what ive done in the interim is to reset the battery powerometer lightbulb thingy and told it to keep the screen on no matter what (within reason) and this should hopefully work. ive also told her to give the battery a full, proper workout to get it back into the habit of working again.
malman, you seem to be my IT query guardian angel of late, so thanks! - still no joy on the router though, god im going to enjoy smashing it to bits when i get another one!
did you ever sort your fuel level sender problem out stefan? i thought i had a similar one on my seven when, after trailiering it around and approx 1 mile of service it tried telling me its tank was only half full after being brimmed previously. turns out i had a blocked breather and, while on the trailer (over about 5 days) it pressurised the tank and pushed about 4 gallons (no exxageration) of LRP out onto the back panel. took the paint straight off and it looks a hell of a mess
maybe you got off lighter than me?
