Should I update my BIOS?

I have noticed my bios is from 2015

 UEFI: American Megatrends v: 5.6.5 date: 08/29/2015

I’ve only had the pc for a month, it came with Windows 10 but I never ran it, just loaded Manjaro on top of it.

However, my system works fine, Should I update the bios ???

And if so, how do I update it?
(only ever done that on Windows about 20 Yrs ago).

If it ain’t broke don’t fix it is the usual advice.

It’s possible new BIOS updates fixed vulnerabilities and improved stability, you can check on your mobo manufacturer website, same place you’ll get a new BIOS rom.

Some manufacturers have a windows utility that can do it for you, some give you a file you need to put on a FAT drive and select in your BIOS, some motherboards can boot from a USB drive with a file and update that way. Once again your manufacturer will have a guide.

Last time I updated my BIOS I had to re-install Linux, but your mileage may vary.


Can’t argue with that sentiment, I completely agree.

Just seeing what other folks think, but if I have to do it eventually I would rather do it now whilst I’m still in installation mode so to speak. :slight_smile:

Thanks for you help :+1:

Even though I hate almost all motherboard Vendors, I would recommend updating BIOS .

It can have fixed ACPI tables for example.
Also some vendors make it hard to update bios externaly and provides some ugly Windows binary and then when you nuke windows out of your system, might loose easy way to flash Bios then.

Yeah, thanks,I think your right there. Probably need to put DOS on a stick if I do it. :confused:

Probably not, I never had to have a dos bootable USB to flash any BIOS.
What is the exact model of your laptop? The exact references can be found on the sticker on the bottom usually.

If you come to the conclusion there is an BIOS update and you want to install it have a look into Hiren’s BootCD:

It could help you to establish a Windoze environment to install a firmware update without installing Windoze.

Thnx. It’s a KINGDEL PO5B-i7-465OU. Vendor site is of no help at all.

OK I don’t think you’ll find any BIOS update for this.

Well, In my experience it helps to update BIOS. I was running a very old BIOS and had sound problem (dummy output) on all kernels except 5.4xx. On the old BIOS my angular button (<>) did not work. However by updating it, it solved the sound problem, making sound option work on newer kernels, and the angular button got fixed.
There were also some security patches for Intel in the update.

So in my case, the BIOS update worked like a charm and solved two problems I was facing at the moment, but of course, your mile may wary.

Thanks you for all your help folks. :+1:

I can’t find anything out there that relates to my board, so…

I think I’ll let sleeping dogs lie and go with the “it’s not broken, don’t fix it” paradigm .
