Bios Mods -The Best BIOS Update and Modification Source

Hello, I got a laptop Thinkpad R400 as a gift.
The problem is in cold boot, BIOS can detect HDD and Windows start ok, but when try restart from Windows e.g soft reboot BIOS can't detect HDD. To start again the laptop must disconnect the power and remove the battery.
What i did:
- update BIOS to latest version - problem remain
- reset BIOS to default settings - problem remain
- change SATA HDD mode in BIOS: AHCI or Computable - problem remain
- change HDD with another new HDD - problem remain
- install another OS: Windows XP, Windows Vista, Windows 7 - problem remain

Can anyone help me with BIOS mod for this laptop so that it can find HDD in soft reboot.

Lenovo ThinkPad R400 model:7440-WSF
