Acer laptop: BIOS update, worth it?

Hello, I own an Acer E5 575G-5622 laptop. Recently bought this machine, it came with 1.12 BIOS version. If I see drivers for my laptop, it also shows me BIOS updates. Currently v1.29 BIOS update is available for this machine.

My question is that is it worth it to upgrade to latest BIOS version? I have read on the internet that it is often very risky to update BIOS as it most probably would lead to corruption of boot loader. If that was the case, why is Acer still shipping BIOS updates for the laptop?

If it is worth to upgrade BIOS, what are the procedures and precautionary steps to take in account?

Thank you!

I'd probably do upgrade in your place - there have been 7 updates since the August 2016 version you are running (1.12) and the current 1.29. Their release notes are extremely brief and so it isn't really clear what they fixed though.

This is from the last one - note they can't even spell "Windows" properly which does question Acer quality control but none the less 7 versions is a significant amount of fixes so I'd probably do it.

Code:

How to update the BIOS: 
Click "ZAA_129.exe" under Winodows mode


Release Note:
1. Update GOP to 1066 and vbios to 1051.      
2. Update EC to v1.10.
3. Update Microcode.

Product support

If you decide to, make sure your battery is charged and AC power connected. Mostly BIOS update problems are due to losing power half way through. Then just click on ZAA_129.exe

I've never had a problem doing BIOS updates (not that that means anything of course).

looking at the description 3- Microcode,

have to assume its a Spectre/Meltdown fix.

Doubt it as it was released last September. Who knows what it does - Acer don't say certainly.

There is something more on the Internet by saying "Don`t fix it if it aint broke". Some people suggest me not to update BIOS UNLESS I am doing it for a very profound reason. Acer is too lazy to dispatch BIOS updates with proper change logs. Now I am stuck in the middle of my decision, should I proceed or not?

That is good and sensible advice applying to almost anything.

I would - but then I'm just some random person on the internet.

Only you can decide - if you have no issues then the safest would be not to bother. If you do have issues then upgrade - even if you don't know what the update does (as they don't say) it might fix it. If you are like me then you'll want to upgrade anyway (even if you don't have any problems) or it will annoy you being on an old version.

I don't think there is a correct answer but updating BIOS isn't normally a dangerous procedure. Certainly I couldn't find any cases of applying 1.29 causing anyone any issue and it has been out 4 months now.

On an OEM system, I always apply a BIOS update. It's been tested for that exact hardware.

On a custom built system, like my tower, I always take a look at what the update "fixes" and see if any of it applies to my configuration before deciding.
