Got the laptop back.
What AUS repair has done was only a HDD reset WITHOUT a graphic driver installed (then "Sleep" is in grey.. don't know what they were thinking)...... the issue is still there.
Fortunately, I've found the problem by myself.
Enter BIOS, "Security"->"Securiy chips", then change from "INACTIVE" to "ACTIVE", then it wakes up.

Let me get this straight, they did a format (by HDD reset I guess you meant format?) of the hard drive and reinstalled windows without graphics drivers? Isn't this what you (and I, for that matter) did like 10 times before sending it back to the repair center? Didn't they see that is still wasn't working?
About the BIOS security feature "fix", I was so sure there wasn't any link with the sleep problem I didn't even try to switch it to "active". Besides, the TPM (trusted platform module) security isn't something I'd be using.
It's interresting though, I'll call my local store (they're a Warranty Service Provider store, and they have a good reputation around here) and have them test it. If it does fix it I guess it won't hurt to keep it turned on.
I'll update this thread when I have feedbacks,
thanks a lot

"Format/Load HDD" is ticked on their "Service Activity Report", then the machine when I turned on after got it back had no graphic card driver installed.
You're right, we did it for 10 times or more, but that was what they did on my laptop.
Anyway, I am now pretty sure it is something with BIOS setting. If I change it back to INACTIVE, won't wake up from sleep with same symptom before.

I called my repair shop this morning and yes, the BIOS setting did "fix" the problem (he was as surprised as I was).
They'll make sure though that the problem isn't a more serious one, as Frensel noted, and call Lenovo to have confirmation they don't have to change something inside (ie. the motherboard).
Will update this tomorrow.

Thanks Frensel, btw.
Well I got my laptop back. They (local computer shop, they are Lenovo's warranty service providers) didn't do anything.I should have kept my mouth shut (not telling them about the BIOS "fix" ) and let them change my motherboard(as were about to do before I let them know about this "fix" ).
It's fine if sleep mode works well, but I'm affraid my video card problems (video card crashing and giving me the message "your video card drivers have recovered, etc.", and sometimes bluescreens (two in a week) because of this) will still be there.
Man.. Is this the ever most disapointing purchase of a laptop.
I'm about to return this W500.

It says S1 is not supported. This is not normal.
Yes it is. Notebooks typically use S3 for sleep, which powers down all fans, etc. S1 sleep is "power-on-suspend," which leaves all fans running and most peripheral cards are still on as well. This is like the old days in desktop land with APM - machines "stayed on" but were "Asleep" inasmuch as they used less power in this state and the CPU was completely halted.
Have you tried the latest BIOS? My machine shipped with 1.13 but 1.15 is out. Sleep-related issues are often fixed by BIOS updates...

I'm having the same problem with a brand new t400; the computer goes to sleep and will not wake from sleep without rebooting. So unbelievably frustrating.
Could you explain how you went about the BIOS fix?
