Lenovo Thinkpad L460: Problem with screen or motherboad?

Tue, 04 Nov 2025 05:14:47 -0700

My lenovo T460 has no 3.3V and no other voltages on screen controller board (CON) except the 20V on the connector and in a big coil. Also no backlight and no picture. Is it possible to have fry anything in main motherboad ? (My hdmi output working normally with my external monitor).

Initially I changed the screen cable, because my screen was changing colors and making vertical shades with freezing picture, especially when the lid was moving.

Initially the problem seems to had be solved ,but after 5 min the problems return, so I opened the screen and begun probing on the CON for voltages and any defect cups and at that time the backlight and the picture was on, with the defects showing..

Now it's only a black screen.(with working hdmi output to TV)

The question is how do I know that I haven't done anything wrong with the motherboard, while I was probing the screen con board ? The 3.3V and other voltages are coming from the motherboard though the screen cable or from the lcd controller board?

Where could I have to start searching ?

I Appreciate your time

Lenovo Thinkpad L460: Why is my laptop power button not working?

Mon, 06 Jun 2022 03:13:18 -0700

Actually mine is L430 series. since I cant find the device in dropdown list in choose device, then I choose L460.

Why is my laptop power button not working? After shutting down, I tried to turn on my laptop by pushing the power button and it does not turn on. Try to hold 5 seconds but still does not turn on. Then I tried unplugging the laptop, took out the battery and connected only the charger and it worked. Laptop is on. I tried to feel and push the power button, I can feel the button clicking but not responding. Is there any solution before I replace whole the keyboard?

many thanks
