I have for long used a T500 (Libreboot+Trisquel, no battery) as a TV.

Recently, it often does not start when I press the power button. Except if I first un- and replug the power cable.

Any idea on what the problem is and how to solve it?

This reminds me of a faulty capacitor that similarly hindered power-on. One had to unplug everything from the laptop, including any sort ot usb adapter or peripheral, and of course battery, and press the power button for at least 20 seconds, after which things returned to normal. It was a different brand, but I would imagine that capacitors must be quite similar, possibly even manufactured on the same line.

So there's that.

Unplugging everything was crucial (wireless mice sometimes have really tiny adaptors), as was the 20 seconds delay.
