Lenovo ThinkPad X270: What is broken? No display and Power / Fn buttons flickering

Mon, 05 Jan 2026 07:02:49 -0700

I'm asking because I've never encountered these symptoms with any computer ever before.

Symptoms:

flickering power and Fn buttons
laptop screen blank

I replaced the mainboard of my X270 with one bought from a Chinese store. I've done that before on other laptops of the same model and with different models. although no professional hardware technician, I'm familiar with that kind of work.

I installed the replacement and booted up. The symptoms are as described above; the laptop screen is staying blank and the power and Fn buttons are flickering. Not blinking, flickering. This does not at all look like a post error blinking, it's way too fast.

The flickering might have a pattern that repeats after a pause, but that's just a feeling and I first need to actually record the timings.

With an external screen attached, the system can be used fine, but the flickering of the power button persists.

It's a very weird error. Do you have any clue about what could be broken and how does it cause the symptoms. Or are they unrelated?

I'm baffled.

p.s.

I rechecked the flickering of the Power and Fn buttons; there is a pattern and it's five flashes in about 0.5s, every 1s.

I have the led on the lid flashing three times when I apply power.

Lenovo said this means power is applied. I should get corresponding flashes on the led inside the power button. I don't get this. Does anyone have any idea why
