It's extremely unlikely that there is anything wrong with the bios on your netbook, unless you attempted to flash the bios and the flash failed.
If you did do that and the flash did fail, re-setting the bios cmos is useless.
It's extremely common for device makers and software makers and people who provide provide help on the web to suggest you may need to update the bios version of your mboard, or to reset the bios cmos when you're having a problem, but 99% of the time that has absolutely nothing to do with your problem.
Tell us in as much detail as you can come up with what you problem(s) is / are.
What I can tell you in any case .....
You can go into the bios Setup and load bios defaults, which does the same thing as re-setting the cmos, except the current date and time are retained when you load bios defaults.
If you can't get into the bios Setup because
- you have no display at all, you have some other problem.
- you don't know the password to get into the bios Setup, or the password to use the computer at all, or the hard drive access password, the password info is NOT stored in the cmos portion of the bios chip - it's stored on another chip on the mboard that CANNOT have the user data on it erased by removing power to it.
If you, or anyone else who has access to this netbook, have
- dropped this netbook, or have dropped anything on it, or have subjected it to a physical jolt
- spilled liquid on it, or exposed it to liquid such as rain, or have sprayed it with liquid
those are the most common causes of components getting damaged inside the netbook and needing to be replaced.
If your computer is not starting up at all, or if it does start up and you see normal video initially but Windows is not loading properly, that has absolutely nothing to do with the bios, unless it is not starting up at all and you attempted to flash the bios and the flash failed.
If your computer works normally but you can't connect to the internet wirelessly, that is a common problem and that has absolutely nothing to do with the bios, unless the .wireless adapter is built into the mboard and it is disabled in the bios Setup - you, or someone else who has access to the computer, would have to have done that.
