Hi. I've got a Sager 4020 which is 2.5 years old.
A few weeks ago I noticed a little flicker on the screen but then it went away and I forgot about it. This Sunday, it started again, much stronger, it got worse after a while, and then the screen failed. The LCD per se was still working, but the backlight turned off. I have a little utility which turns the screen off when I press Ctrl-Alt-F10 (like a blank screen saver but un demand).
So I turned it off and then moving the mouse the screen came on again... for a couple of minutes, then the flickering started and off it went again..
Now it's up to the point where I have to use an external monitor in order ut use my laptop!!
After the screen is off for several minutes (or overnight) I can turn it on and it will last 2 or 3 minutes, where everything looks normal. Then flickering starts and the backlight turns off. You get the idea!
First I thought it was the backlight, but then googling around I found that it could be something called the "inverter" which powers the backlight. And it would be much cheaper to fix!!!
Anyone has any experience with it?
May be related: The circuit which powers the LCD (I'm guessing the inverter is in that PCB) also has 3 leds for "power", "battery", "email/wifi".
The third led started blinking orange a few days ago (normally it was a static green when wifi was on). Blinking orange is not an expected/documented behaviour for this led.
How do I know?? Because I opened the LCD lid and looked inside!!
Could these two problems be related?
I would attach two pictures, one of the LCD model, and the other of the alleged inverter PCB but I don't know how to do it!!
