This summer I was away for about a month, and when I came back, recovering from hibernate had gone from being slow to unbearably slow. I could understand it being just one time, but ever since it's been like that. And the worse thing is that you have to sit there the whole time tapping the keyboard, otherwise it goes back to sleep and you have to do it all again.
Hybrid sleep is enabled.
Other strange-but-possibly-significant symptoms:
- I tried disabling hibernate, the effect was that any time I tried to put the computer to sleep, it would wake up with a 'Windows failed to shut down correctly, would you like safe mode...'
- Prior to this, when the computer went to sleep, the power button would flash. Now it doesn't.
(I'm hesitating about doing a system restore, but the last time I did a backup was 4 years ago, so I'm not really looking forwards to manually updating 4 years of changes.)
As advised by magicandre, here is one of the outputs from WPT. Is this any help?
