Laptop Screen Backlight Types...
As we all know, some laptop models can be manufactured with more than one type of backlight.
As far as I know, the only way to determine the backlight type for these type of laptops is to actually pull out the screen and look at the connections. Is there any other way to find this info without having the laptop in your possession? Thanks for any feedback...

Do you mean CCFL or LED? Otherwise, the CCFL connections are all the same...at least, I've never come across anything different.
Edit: I think the answer to your question is that it's best to disassemble it and look at the screen. It's not a good idea to try to guess the type of screen based on the model. There are models with different panels, including some that sell with CCFL or LED backlights as options. Last edited by 14049752; 10-05-2010 at 03:54 AM.

Maybe I didn't explain myself right. For example, a customer calls with a cracked screen. he/she gives you the make and model of their laptop. You look it up and you see that it comes with different backlight types.
Is there anyway to know which one the customer has without having to go to customer and look at their laptops in person?

i would never buy a screen with out taking it apart and looking at the number on the back of the screen, as thier are loads of laptops that have serveral compatible screens.

Some laptops (I have found) are easy to identify.
Dell Laptops: get the service tag, go to their support site, go to original configuration tab, find the part number for the LCD. HP: the part number (not serial) of the laptop can be used to find which parts that were shipped with the system (sometimes). Of course... nothing is 100% without looking at the system yourself.

I'm not sure how that explains what you're asking any better. The different backlight types would be CCFL or LED....there's no way to easily tell which screen is in the system, because some models have the option for both types. It's generally a bad idea to order a screen based on just the model of the computer, especially when you're dealing with one with different screen options.

Insist that you must take apart the laptop to find out what the part number you may need.
this came from a different thread about another issue I had. Sony's VPC models can shut off the LCD backlight if it detects that you switched its board and it must be reset by Sony to return it to normal operation. If you have a Sony VCP models with cracked LCD panel be careful. (that came from the tech who sold me the panel, just some info)

I'm a bit dubious of that. Switched which board? The inverter? The motherboard? I don't think that guy knew what he was talking about. Edit: Yes, even more dubious. I just talked to a buddy at a Sony authorized repair center. He says there's no such thing, to his (quite extensive) knowledge. Last edited by 14049752; 10-05-2010 at 09:21 PM.
