Hello everyone,
I have a Lenovo V15-IKB that had a damaged motherboard. I replaced it with a motherboard from a Lenovo V15-IIL.
The board powers on, but it shuts down after about 10-15 seconds. This only happens when the internal display (LCD panel) is connected.
Here's what I've tried so far:- When the internal display is disconnected, the laptop works perfectly fine via HDMI.
- The laptop shows an image on the internal display for a few seconds before it shuts down.
- I tried swapping the LCD panel with a known good one.
- I tried swapping the LCD cable

Hello everyone,
I'm currently diagnosing a MacBook Pro A1707 motherboard that does not power on. I've gathered some data but am stuck and need expert advice.
Note that i'm a beginner in electronics and i'm trying to learn while trying to repair this macbook that my work gave me. I'm really curious and love understanding how thing works and i already learned so much.
Only one usb c port is taking 20v and have 12.5v on PPBUS_G3H. when trying other ports, 2 are not going to 20v and one is going to 20v but the CD3215 is getting really hot.

Hi everyone 😀,
I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.
To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.
Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:- I already own the exact same model, but its plastic chassis is badly damaged.

Subject is a blank screen issue in HP Envy 17-3290NR 3D version laptop with motherboard Louis V1.1 6050A2489901 MB-A02. Production year is 2012. This one is a 2nd hand motherboard which I could use it for few months only. Suddenly no output from the internal display and also no signal from HDMI port then Windows out of order after few boots.
Caps lock working normally and no HP's caps-lock warning blinks. Making a hard reset and replacing the RAM sticks or using different slots didn't help.
Fans are spinning. Blindly could install windows11 and got the device manager...
