When updating your motherboards bios, you need to firstly find and download your motherboards bios update. Check the manufactures site of your motherboard.
Once you find your bios update, its important that it is for your own model motherboard, then they usually include a text document with the instructions on how to install.
It is usually done by a Floppy Disc and is known as "Flashing".
So first find out what make and model your motherboard is, then search for the latest bios update for that particular board, download it, read the instructions that come with the download. Or search "How to update your bios". Instructions are often given with download though.
Yes, the bios can be upgraded.
Where to get the update depends what type of computer you have.
If you have a brand like HP or Dell, then you have to find your computer model on their website in the support section.
If you bought a nameless computer then you would have to go to the motherboard manufacturer website in the support section to download it.
In both cases, they usually have a software to install which would make the upgrade really easy. You have to make sure you download the right bios upgrade for the exact motherboard you have or you could brick you computer. You could verify the list of corrections for the new bios, if you don't see anything that could fix your situation or no new interesting features, there is no point.
Use a special program from the manufacturer to update the BIOS.

It's not really clear how much a BIOS costs since they're not marketed to end users but are sold to motherboard manufacturers. A BIOS is essentially a part of a motherboard. A BIOS is likely to be removable on a modern motherboard and technically it could be possible to replace a BIOS if it went bad or if for some reason it was to be upgraded, but for BIOS upgrades usually it is sufficient to flash (reprogram) the existing BIOS.
Read Only Memory(ROM) Basic Input Output System(BIOS) or firmware chips are "Electrically Erasable and Programmable Read Only Memory(EEPROM)" chips, these kind of chips can be upgraded by flashing.

If this is correct, it sounds as though you flashed/upgraded the Bios on your laptop. Bios flashing is never an easy thing to do, and if done improperly, it can render your computer as one giant useless paperweight. This usually occurs when an incorrect version of the firmware has been flashed to the BIOS. If there are no beeps, no display, only a power light, then you'll have to replace the BIOS chip itself. You'll have to bring this into a computer repair shop/store to do this. If you are lucky enough that the boot sector of your BIOS didn't get corrupt and your computer still posts and you can put in a floppy. Then all you have to do is follow your normal dos based flashing and it'll replace it with the CORRECT BIOS.
