T430 BIOS upgrade

[rjsrjs]

Is there any reason at all I should upgrade (if possible) my Lenovo T430's BIOS? I'm currently running Linux Mint 19.1 and all is running well. If so, where do I get it, how do I do it. I have never done this before and don't want to brick my machine.
Also I seem to have a problem with Fn>F4 sleep keyboard button. It doesn't do anything when pressed. I made a keyboard combination using Crtl>Alt>S to put my computer in suspend mode. The F4 problem is no big thing, I'm just curios.
Here is the info off my machine.

Type: Laptop System: LENOVO product: 2347C32 v: ThinkPad T430
serial: <filter>
Mobo: LENOVO model: 2347C32 serial: <filter> UEFI [Legacy]: LENOVO
v: G1ET45WW (1.20 ) date: 08/07/2012

I wouldn't do a thing. Sure updating the BIOS from Lenovo's support site will probably do no harm 99% of the time. At this stage in the T430's life cycle the BIOS is old, matured and tested. I doubt you'll notice any performance difference. If it ain't broken don't keep fixing it until it breaks.

Not in agreement - Lenovo is still providing bios updates in 2019 for T430. You should at least update to BIOS 2.81 (G1ETC1WW) EC 1.13 (G1HT35WW) issued on 2019/07/04 which include various intel CPU [censored] fixes and that bios still allows you to modify the EC to whitelist batteries and use old keyboard mods. The fact that your CPU is old and made by Intel is one of the biggest attack vectors for the coming years and why we should start moving to newer CPU's with our thinkpad addictions.
