Device: Thinkpad X280 (refurbished)

  • Intel i5 7th gen
  • 8GB LP?DDR4 (soldered)
  • Windows 11 IoT Enterprise LTSC

My laptop is not turning on, and there is absolutely no signs of life. No lights, no fans, no heat, NOTHING!

What was I doing before the problem: It was just a usual day. I used the laptop to do some office work, I shut it down (I think it had a Windows update with it that day), didn’t use it for a day after that, and now it wouldn’t turn on when I needed it.

Things I did to fix the problem:

  • Removing the battery and the CMOS for 2 days and reseating doesn’t do it. Some guides even said to press the power button (without both or either batteries) or the reset button at the back of the laptop (tried with and without both or either batteries). All of them didn’t work.
  • I checked if it was even receiving power in the first place, by:
    • Plugging in the charger on either USB-C ports (with different chargers, all of which are working on other laptops). Doing this, you should see:
      • the dot in the i blink three times light up
      • the light beside the port or the power button light up
      • the peripherals plugged in (mouse, keyboard, etc.) light up
      • All of them didn’t work.
    • Letting the laptop plugged in for an hour to see if it gets warm. It was colder than my girlfriend.

I’ve tried everything I can. I’m left to think it’s a motherboard problem and I’m gonna have to let this be fixed by a technician.

Is there nothing more I can do?

Please help.
