I transformed a cosmetically damaged gaming laptop into a desktop, but I still have some questions.
Laptop: I purchased a gaming laptop from a local seller in a Tim Hortons parking lot for $150. It arrived in very poor condition—screen cracked, hinges broken, and plastic pieces scattered everywhere—but it functions perfectly except for the display. My concerns are: 1) The power button is built into the keyboard, and I’m struggling to locate the ribbon cable pinout so I can solder a replacement switch. If you know what the pins look like, it would be helpful. I’d prefer to replace the keyboard if possible, but any guidance on removing it would be appreciated. 2) The old screen was a 15-inch, 30-pin 1080p IPS model. I need to swap it for a smaller 30-pin version so I can reach the BIOS. Since the laptop relies on integrated Intel graphics for initial display before booting, I want to connect a smaller 30-pin screen from the same brand. I’ve tried using a 40-pin model before and had success with a used Acer Chrome book (11-inch, 30-pin) for about $25. I’m planning to mount it on the case I built, which is made from scrap parts but will include proper standoffs and cut sheets. I’m open to suggestions other than discarding it—any advice would be greatly appreciated. Thank you.
There are methods to modify that internal DP link for a complete setup. Concerning the keyboard power switch, I attempted similar changes before and had trouble locating the pin configuration. It seems logic exists in the keyboard to enable this, though you might be able to work around it. You could also check for a 'wake on LAN' capability that functions as a power switch.
It's best to check the specification sheet or data sheet for the IO chip on the motherboard, which should be responsible for triggering. There are eDP to DP adapters available.
The power key was always distinct from the rest of the keyboard layout for clear reasons... you could simply test the flex pins to determine its link. It's very probable it sits between ground and a single trace, so shut off power to the entire unit, keep the keyboard's flex active, and place one multimeter probe at any accessible ground point. Press the key and move the other probe along the connector. If it beeps or displays lower resistance, confirm it's correct by releasing the key.
Great job, my friend! I just placed an order and it works perfectly. I can now connect two monitors and access the bios. Thanks!
I appreciate the wake on LAN concept. From what I grasp, I can use my mobile phone to activate the PC both nearby and from a distance. I plan to incorporate this capability into the design. A moderator shared an excellent suggestion to locate the power button pins for testing.
Great suggestion! I’ll give it a try and share the results once I confirm everything functions well. Please let me know if you need anything else.
Ugh, it didn’t work and had to be canceled, but thanks for being there.
I believe it's a control board designed for an LED panel, receiving DP input and displaying it on the laptop screen. I'm also searching for an adapter to convert the eDP signal from the motherboard into DP, though I'm open to using HDMI instead.
