T490 Will Not Boot

2021-03-15, 19:46 PM

I have a T490 that will not boot.  When the power button is pressed the power light illuminates and the capslock light and a few of the function key lights flash.  The power button stays illuminated, but the others stay off.  The screen never lights up or shows the splash screen (or anything else).  I have tried:

  1. Reseating the battery connection
  2. Reseating the CMOS
  3. Reseating RAM and SSD connections (Also tried to boot without them installed)
  4. Tried to boot without the battery, only the AC adapter
  5. Charged the notebook for over an hour
  6. Disconnected the batter, AC adapter, and CMOS batter for 30 minutes and then tried to boot after reconnecting them
  7. Tried to boot with an external monitor connected via HDMI
  8. Pressed the reset button on the bottom of the notebook

Does anyone have any other suggestions?  I have about decided that the motherboard is toast.  Thanks in advance.

Hi JB789!


Welcome to community forums.


Yes, there is a possibility that the motherboard is faulty. You can have it checked at any of our list of authorized repair centers. You can find them here: https://pcsupport.lenovo.com/us/en/partnerlocator
