There's a feature of this Chromebook that I utterly despise. When the device overheats it shuts itself down to preserve the hardware and prevent damage, the problem with this is when you're working and have a bunch of tabs open, the laptop will shut down with no warning it's absolutely terrifying. I hate it, it's caused me so much trouble.To get the Chromebook back on pressing the on-button alone doesn't work, you have to press the on-button and the refresh key on the keyboard and hold them both at the same time for 10 seconds for the device to turn back on.Also, I'm having trouble downloading files, which is a minor issue, but still annoying.Don't buy this, just get a MacBook off eBay for about the same price, hope this helped.
