I'm having a very weird boot issue with my brand new 5810TG: whenever I shut it down or put it to sleep it just reboots and the Windows Recovery screen pops up telling me that the system was shut down unsuccessfully.

Specs:
CPU: Intel SU9400
GPU: Hybrid: ATi HD 4330 and Intel 4500HD
BIOS: latest (1.20)
RAM: 4GB DDR3 @ 1066MHz
HDD: 320GB @ 5400RPM
OS: Windows Vista Home Premium SP1 32bits

Has anyone encountered this issue before?

NOTE: I haven't installed anything on it besides what it came with. I did update to the latest BIOS, but that didn't help.
Looking @ Acer's driver support indicated I have the latest drivers.
Googling didn't turn out anything either...

Return it under warranty repair. Could be a problem with the hard drive...

The key words here are "Brand New"

Ah... well I was wondering if I could fix this here and now.
I currently can't get it to service since it's "technically" not mine and it cant be serviced for the next 2-3 weeks.

I tried reinstalling both GPU drivers and updating the BIOS to the latest available, but no dice.

If anyone comes up with any other suggestions, I'd very grateful!

You will void the warranty if you mess with the hardware... Wait the 2 or 3 weeks, you will be glad you did

haha!! I didn't say I would toy with the hardware.

You wanted to fix this yourself... messing with hardware would be the next thing to do
