I have the Asus notebook discussed on this thread (http://www.pressf1.co.nz/showthread.php?t=98069). (it's an Asus M51VR).

It's quite new. The problem is that the screen changes contrast for some reason about twice or more per minute.

It fluctuates between being normal then a bit bright, then back to normal. It's only just faintly noticeable, but it's very distracting.

My question is... is it worth sending it in to Asus under the warranty or could it be just a software setting?

It's my Internet computer now so I'm reluctant to part with if I don't have to. I also don't really want to have to pay courier costs.

It sounds like the inverter might be on its way out. Yes - send it back under warranty while you can.

I agree. It may be painful to claim on warranty but it does look like a hardware problem, especially if it does it with all programs/windows screens.

Thanks both.

It's a damn schlep, but ah well.

Just a follow up to this issue... spoke to Asus helpdesk. The guy said it was to do with the Ambient Light Sensor. He said simply to press Fn + A to disable it.

Lo and behold - problem solved!

Gawd, and they needed to put one of those on the laptop why? :o :lol:

Silly little things like that are always the bits that break, I've got one of those light sensor do-dackies on my Bravia TV, never seems to work like it should.

Not sure either why they needed to have a sensor of this type on this lappie.

I mean really, if someone can afford to buy a notebook from them then they'd be compatent enough to know how to turn a wall light switch on or off!

:lol:

Nevermind... the good helpdesk response was... good; so can't complain.

Gee guys, its to do with battery life.....if you noticed when on battery, the LCD dulls so not much power draw, however it is controlled by ambient light to control how bright it is.....
However Greg, remember the your problem is NOT cured, they have simply turned the broken, failing sensor off!

True - But most notebooks I've used will darken the screen when they are running on battery anyway, they just sense if there is AC power going in or not. Don't really need another sensor to darken/lighten it more I would have thought, it's normally pretty easy to change the brightness of the screen. :2cents:

I haven't used this notebook on battery power since the first day I bought it.

A failing inverter or CCFL will do a different kind of flickering (you can tell because the screen goes dark like it's turned off)

If the CCFL is old then you may also get a pink/red colour on the screen as well.
