My Asus G50Vt failed to enter standby properly. It shut down the display and the fans but left the CPU running. The heat melted the case and the keyboard. I'd say that the risk of a fire is real.
Standby and low power state support is a complete mess in the PC market
For every confiuguration it has worked on, I have seen it cause major issues on two more.
I am just recommending SSD and full shutdown to people now; When a PC boots in 15 seconds and is immediately responsive, they don't mind. It's far better than the 90-second boot, then 3-minute horrific disk crunching that happens on a mechanical disk, and with a full shutdown, you get all the benefits of a reboot more frequently (I'm looking at you
, Adobe, with your unstable, memory-leaking excuse for a product range).
