Hi!
If you upgraded your stock CPU Pentium or Celeron to any Core i3, i5, i7, then your laptop will starts shutdown exactly every 30min.
Unlocked bios can't help with this problem. It's hardware specifications for Mobile Intel HM70 Express Chipset.
The highest processor you can use with Mobile Intel HM70 Express Chipset is Pentium 2030M.
