How to get to an Acer Aspire 5534 GPU? - Page 2

post #11 of 20
If there is an image on the screen, that you can see if you shine a light on it sortof indirectly, your issue is with your backlight, I haven't had a chance to play with any LED LCDs on a laptop yet, so i'm not sure if they have the same inverters that CCFL screens do. On those they are seperate units from the screens. I wouldn't imagine LED screens need an inverter, but if you got no light, thats certainly a problem.

Plain and simple though, if you get an image on an external monitor, your GPU works, and getting access to it will do you no good as its probably soldered onto the mainboard.

Yes I know how to use a multimeter...
Take the cable out and check pin to pin. also make sure that the pinouts from the board to the LED's are supplying power. Ill have a link to the notebooks service manual here in a moment.

HERE is the service manual. Very useful.

My thoughts as well just using basic computer logic. I work on Desktops mainly so I wasn't sure thanks.

My last post is updated with a link to the the service manual. I'm looking through it for the location of the switch, but its usually a part of the hinge nowadays.

I cant SEE it, but its there somewhere. Oftentimes its a part of a board, be it the power board, IO board, or the logicboard.

It has one, else how would the Laptop know its closed?

Apparently its a surface mounted switch on the logicboard. Although I haven't located an image or diagram of its location.

I've got to get ready to get some teeth fragments removed from my face. So I bid you good luck. Every laptop is a pain in the ass. I promise., but they are just as serviceable as a desktop. Can always be fixed.

I have replaced these hundreds of times.

LED backlit LCD's don't have an inverter. LED's are DC current.
CCFL's also use 700v

I don't know if its the fact that my face is twice as big as earlier and I'm fizzed out on Vicodin, or the fact that that was COMPLETELY random, but where is the relevance?
