In reply to Danillo. I'm not sure if this is any help but here's what I found: https://bit.ly/372J3fz It has QUANTA AM9A MOTHERBOARD SCHEMATIC DIAGRAM. I think you you need full schematics with the board-view, you'll need to search on google and buy them. Usually they are not free.

In reply to IML Tech. I see. Sorry to bother you. Do you know how I can find the schematics? I saw there are some codes beside every component but I struggled to find it (I'm not a hardware technician nor English native speaker lol).

In reply to Danillo. Danillo, I don't fix PC motherboards on the component level and don't know the location of the fuse. In order to find the backlight fuse you'll have to have the motherboard schematics. From my experience, if the screen backlight goes off, most likely there is a problem with the LCD screen itself or the display cable. You've replaced the display cable already so the screen is the next.

Very insightful guide. Thank you very much!

My laptop screen has not been working properly. The image shown is so dark that I can barely see it. Thanks to a secondary monitor I was able to complete my tasks. I tried changing the screen flat cable and nothing has changed.

Doing some research I found there is a slight possibility of being a blown fuse. Do you have any idea how I can manage to find the screen fuse in the motherboard?

Thanks in advance!

In reply to rexzone. @ rexzone, I'm not sure where the lid close switch is located on this particular model but most likely it's a magnetic switch. Use a small magnet. Move the magnet along the perimeter of the display and palmrest assembly. The location of the lid close switch will be at the place where your magnet sticks to the display or palmrest.

Where is the reed / lid switch located? Is that what happens if I leave the screen open, the screen does not turn on, if it closes it and I open it, it just works, and then I open it all, it works fine but I can’t find the piece that you see if the lid is below or above

Hi there, do u still own this laptop ? I would need to see cabling on the power jack side if it is possible. I have broke the jack wires and i dont have an idea about wiring. You have the jack on the photo from the front side and i would need to check the backside for the wire diagram with colors.

Thanks in advance

Hi, I wonder if the red accents can be modded? I’d like to change the colour on every single one of them, make a less gamey machine.

Thanks for the instructions! One of the fans started making lots of noise last week. I’ll attempt replacing it myself. The fan noise drives me crazy!

In reply to Matt. @ Matt, Most likely it's not a hinge related problem. It's related to the bottom case. There are only two screws securing each display hinge to the bottom case as you can see in the step 13. I think in your case both screw anchors got pulled out of the bottom case. I think it will be a pretty common problem with the Inspiron 5000/7000 series laptops because the display is pretty heavy and two screws per hinge is not enough to support it. You will have to replace the bottom case. Basically you'll have to go through all disassembly steps. I believe that Inspiron 5577 has the same (or very similar) design so my guide should work. Here's the bottom case part number: 08FGMW
