Have you plugged the faulty computer into the direct source of power was my question. Your test does not tell one what one wants to know -- that the PC is capable of working correctly under some circumstances and not others eg slightly low voltage .....

I would be more likely to suspect the power supply unit than the motherboard since the light on the PSU is changing according to what you say. But I would check out every scrap of information you can get on the Lenovo website before spending money and I would use a voltmeter on the PSU output if I was able to do that safely.

Otherwise take it to a small PC builder/repair shop -- not one of the box stores.
