Laptop BIOS hax

[satikas]

Hey,
I found a guy who had posted an article to help HP owners reduce their system fan noise by manually editing the DSDT file. Its located here: http://notebookequus.blogspot.com/

Basically its all about finding the right spot (fan voltages) in a ASL file you created and then loading the changed with with cmd.exe. Ive found the section that im 95% sure is the fan one, because the hex values make up:
100 50 0 10 20 30 40 50 60 70 80 90 100.

Now my question is, WHAT IF something still goes wrong.
Could I ruin my laptop (I dont mean by overheating)? What I am currently thinking is that any messed file changes could be still "reversed" using, in the worst case, format C. Or are these changes somehow being transferred into BIOS and therefore one could seriously FK things up?

Waiting for expert reply. Thanks.

You can potentially be trying to fix a small problem and create a very large problem for yourself. If you are tinkering with a BIOS you can potentially destroy a motherboard. Ruin the motherboard on a laptop and your system just won't work.

Here is more information on what a BIOS is:

A basic input/output system (or BIOS) is the software that determines what a computer can do without accessing programs from a hard drive or other secondary storage devices. On personal computers, the BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and other miscellaneous functions. The BIOS makes sure all the hard drives, ports, operating system and central processing unit function together. The BIOS is typically placed in a computer chip on the motherboard (it is often called read-only memory basic input/output system or ROM BIOS). This ensures that the BIOS will always be available and will not be damaged by hard drive failures.
