You're welcome!
Fujitsu Siemens is the Make of the laptop; a model number would be something like "Inspiron 1545" or "VAIO VGH-FW139E". The reason we ask this is so we can help look up the website with the appropriate BIOS version for your exact model should you pursue doing the update yourself.
The answer I would give you is it's not Hard, if you've done it before, and have undergone proper training on how to do it. I've taught Technicians and Engineers how to do it in professional certification classes for 14 years, and many of them even with Insructor supervision during lab sessions still fail to do it correctly on their 1st attempt, and "brick" their Motherboards. We used donated computers at some schools and the College I taught at so it's not a big deal in a Classroom lab environment. However, if you "brick" your Mobo it could cost you from $175-$1500 to replace, as I mentioned.
Thus the Warning I provided. Think of it as taking apart a Transmission on your car; it's not that difficult once you've done it before, and you've been trained how to do it in a Classroom environment with an Instructor right their to guide you. But, most people unless they are very mechanically inclined can take a transmission apart on the first try, but very few probably 99% will fail to reassemble it in working order.
Would you take apart the Transmission in your car if you've never done it before?
Especially if that's your only car and you need it to get around town, go to work, take the kids, run errands, go shopping etc.?? If you answer
NO to any of these questions, that you cannot afford to have your car broken because you took the chance on fixing it without proper training, then you should
NOT attempt the BIOS update--pay a professional to do it. It's usually $35-$100 US and is a whole lot cheaper than having to replace your Motherboard; that too takes skill so if you haven't done that before and you "brick" your Mobo and just order a replacement board, just the part often costs $100-$400, so IMO it's not really worth the risk.
However, if this is just an experimental laptop you use for a "lab-rat", and not a "daily-driver",
and you have another computer (desktop PC or another laptop/tablet) to use for everyday tasks, then you may consider to attempt it. Since you are new here and we don't know you or your situation, we are left to guess about this, but like my analogy above, if this laptop is your only computer, like the only car scenario, you don't want to "experiment" on it like you'd be doing if you weren't professionally trained to perform a BIOS update.
I think you get the picture.
Let us know how it turns out and your Model number of the laptop. Sometimes, laptop makers will put the Model number of the laptop printed inside of the battery compartment, so you may need to remove your battery and unplug it from the Wall outlet (MAINS) and get a flashlight and magnifying glass to read the numbers.
