BIOS memory storing and recall

25 pts.
Tags:
BIOS
I am on Windows 7 home premium installed on a Dell laptop studio 1555 and using Outlook on MS Office 2003. All works well. However if I remove and destroy the hard drive and RAM for security reasons and sell this computer onto another party, is there any risk that any information has been stored on the BIOS or for that matter on any other device on the laptop, which could be retrieved by others?

Software/Hardware used:
Windows 7 Home Premium and M/S office 2003

    The only place your info is stored is on the hard drive.  RAM is erased when you turn off.  Pull out the battery for a minute or two.  BIOS contains computer ID and very little more.

    If you want to erase your hard drive securely, download the Secure Erase utility from UCSD CMRR. Everything that you ever needed to know (and more) about cleaning reasonably modern hard drives is there. You won't find anything faster nor more secure, though some highly restricted (e.g., NSA) environments might require more. For any PC that runs Windows 7, it's as good as it gets and all you'll need. -- Tom

    There is very little resale value to your laptop without the hard drive.
