Simple test

Hi, first of all, could you do a quick test? Start the notebook as you normally would, listen for the windows startup sound, this will be the first indication it is loading the OS. One you've determined it is at least to the log on screen, hold your screen up to the light, or preferably, take a bright flashlight and shine it fairly close to the screen. If you see the log on window, enter your desktop just to be sure. If it is functioning, it may be a bad starter board or backlight issue. If you have no desktop or log on screen, it could be something else. Could be simple as it's in sleep mode, or you turned down your brightness accidentally.

Do you mean

Do you mean inverter board maybe? I've worked as a hardware tech for 2 years professionally, and for probably the last 10 in a more amateur fashion, and I've never heard of a starter board.

Inverter boards, however, take the DC current used internally in a laptop and step it up to high voltage AC current used in display backlighting. A bad inverter board can cause symptoms such as no backlight or flickering backlight.

And if you see anything at all on the screen, you don't need to "test" any further. You know it's a backlight failure and so you'll need to take it somewhere to be repaired. Either the inverter board went bad or the backlight CCFLs burned out which generally requires a new display panel.

Inverter board, starter board, back-light board, depends where you live. We call them starter boards. So I see that you have never heard of this and based on your personal experience, you judge the world or so I believe that's what you were basing my defragmenting opinion on as well, that the universe did not revolve around my personal experience, yet it seems to in yours.

Requires a new display panel? Are you sure? Then I must be doing something wrong by sliding out these back-lights and replacing them or replacing the "inverter board".

Sigh, the reason I left here years ago were due to these dumb little arguments from people who seem to stalk other people's posts, like you. You have at every angle attempted to go against everything I post. Well, I say this, I only do this to help others, I have a life outside of this and it sounds like you don't. I pity you. Maybe one day you won't have to feel more of a person by pretending to rule in a forum to make yourself feel useful. Unfortunately, you ruin it for those who are only here to help.

Anyway, I'll go back to programming instead of starting to argue on Cnet, it was a nice break for a bit anyway.
