My HP Spectre X2 tablet shuts itself down randomly e.g. I'll be browsing the internet and en jued to ts down and goes to black screen. I then need to turn the power back on , however sometime this happens so frquently that I can't get to the login screen before it just turns off again e.g. this morning I tried to turn it on 5 times and each time it did not finish loading before it turned off so I gave up. It is unuseable. I've seen some other posts re this so obviously not isolated and this is clearly a faulty product. It is not heat related as it sometimes happens within 5 mins of turning it on and it happens when plugged in. I've also run all the tests and they did not come up with a problem. This product is not fit for purpose. I've spoken to numerous reps, v unhelpful. I'm now sending it off to HP to look at. Hopefully they sort it.
