So far what I had in my mind about BIOS update was "STAY AWAY WITHOUT RUINING YOUR PC" because it was a bit difficult process(few years back it was done using only the command line). If you do even a simple mistake it might cause you to throw away your mother board. So I didn't even look at it.

But today when I was trying to install Windows 8.1 on my n5110 laptop it said "Windows 8.1 cannot install on your pc. Please update BIOS". So I had no option but to update BIOS.

 By default, n5110 comes with A09 BIOS version. And the updated version A11 is available for this laptop.

In order to flash BIOS you need to have the binary file (exe file) provided by Dell inc. To obtain that file go to this link .

Then select "Start Here" under "Support for Home"

 Then you will have to provide your service tag.

After that you will have to select Drivers & Downloads from the below screen. And under Operating system, make sure to select BIOS.

Then it will show the updates available, select the latest and download.


Now the scariest part. All you have to do is double click on the downloaded file and click next. Everything will be done automatically. Easy right??? Well I was so afraid to update BIOS, but I just got realized that with the time, even BIOS update got easier. And don't forget to plug your laptop into a power outlet as any power interruptions may cause DEATH to your laptop..

I hope you got everything. I'll try to capture a Screen-cast if I got a chance with one of my friends laptop. But till that, please bear with the post...
