I have a friend that experienced what I think your seeing. Her
laptop would go into suspension (her's also had a visual indicator)
but later she found it would at times be rebooting on opening the
lid. In her case it turned out to be a HW problem
I've had that kind of thing, in the past. It'll appear to suspend and
wake-up when tested for a short period. But if left for a long time,
when you eventually try to wake it up, it's a warm boot from a swap
file, or a completely fresh boot up.
I wonder if the motherboard needs to be set to go into
hibernation/suspend mode correctly, so that it continues to supply
adequate power to the RAM. But isn't, and after a while, the RAM loses
its contents.

There is no point trying to privately email me, I only get to see

I don't think it's pure coincidence that "officialdom" sounds the
same as "official dumb."
