T500 not powering on pressing power button

[matti157]

I stocked the pc 2 months ago, it was functioning perfectly
Now the pc don't start on power button press. See this video https://youtube.com/shorts/omGXhLezkLM? ... -8UhpMdq5q

I tried to remove and retach the CMOS battery, removing RAMS

Any ideas?

Thanks

Remove main battery and charger, press and hold down the power button for 20 seconds.
Attach only the charger and try to boot.
