Lenovo T470. power button blinks three times when DC + AC after few SPI flash attempts.

2017-11-01, 9:32 AM

Hi

I have flashed the SPI with different fw a few times and the platform booted.

I wanted to flash the original dump again and it worked properly.

I made another try (different fw) and it didn't boot so I wanted to flash the original dump again but it didn't boot at all.

The way it behaves is as follow:

 * With AC and DC: the power button blinks three times and doesnt boot.

* With DC only: it wont boot at all

* With AC only: it wont boot at all

  •  My T470 power button was flashing three times and I could not reboot. My IT department told me to hold down the power button for 30 seconds and then wait a few seconds and then hit the power button like I would usually do. It worked. It seems the computer may have gone into some sleep mode and the only way to get out was to hold the power button for 30 seconds and then it worked fine After pushing the power button again as you normally would..  when the power button was flashing three times the escape key also had the green light on to indicate that there was some power. But the computer was asleep.  Holding the power button for 30 seconds woke it up;
