I have Dell Inspiron 7 series laptop. I had to disconnect the laptop LCD to fix the broken holds for hinges. Now that's another story. Coming back to LCD Screen issue, I connected an external monitor using to Laptop's HDMI port. And the laptop is working fine. The power light keeps blinking the code 2 Amber 7 White, but, the laptop operation is not affected by that. Initially, I had to go through Bios setup because I had disconnected Bios Battery, but once that was done, the laptop works fine. I have used the laptop part for sending and receiving mails, downloads and some other uses. Did not face any issues. So, the blink code, as I think, is neither dreaded nor unworkable. It's just that one needs to get used to work with new setup. This message is being typed using the same laptop....err...Now a partial desktop.
So as the title says, the Inspiron 7559 I am working on for my roommate is giving me the 2/7 pattern. It's a nice machine for his purposes. We got it working a few months ago with a CMOS drain, but it only worked for a short while. It sat for a bit and I have done a bunch of looking around, so I know that it means there is something wrong with the LCD screen, or maybe the cable, since the self-check test passes when I do that whole thing... All I want to know is if it is worth it try the cable replacement, or do you think that it is an issue with the mainboard and I need to maybe replace something else? I run a small computer repair shop from my house and have a lot of experience with complicated fixes, so I am prepared for things to get complicated haha but I figured I would at least ask here whether or not it's even worth it.Also, if it's the board, are things replaceable on this motherboard, or do I basically have to replace the whole thing?
