Hello I recently bought a DELL Inspiron 15 5547, which ran Linux. I thought I could handle it, but I quickly decided to install the familiar Windows. An update has appeared for my BIOS, version A05 to A08, but I cannot install it due to an "invalid firmware image". I believe this can solve a problem I have with shutting down the laptop, cause, when I do, the fan keeps on turning, sometimes to the end of the battery. Is there a way to unlock the BIOS and install the update? My brother has the same laptop, albeit without the 1TB and 8GB RAM, and he has no problems. Thanks to anyone who replies,  Alex
