I have a custom built laptop that I purchased from Cyberpower PC 2 years ago. Basically custom with MSI case and mobo. Big mistake since they’re really boning me right now over this issue but that’s another story.
A few weeks ago I came home to find my laptop unable to boot. Wouldn’t even power on as a matter of fact. The AC brick had power running through it so that wasn’t the issue. When I’d plug the brick into the laptop, the “power” light on the front of the laptop would flash red for a second then go out. Normally it stays a constant blue. I tried plugging in any USB devices like external HD and charging my cell phone. All items plugged in via USB will power on. I stripped the entire laptop down to see if I could see any visible issues with it. Particularly the mobo. I couldn’t see any. Used a multimeter to check voltage at points around the mobo. It’s getting power all around it from what I can tell. CMOS battery is fine. What could cause my computer to stop powering on out of the blue like that? I’d like to say it’s a fried mobo, which I can replace myself, but I just want to make sure I’m not overlooking something. I mean, what else could it be?
