Firmware updates are just as likely to contain a new nasty bug as they are to fix one.
Updating firmware should be done when commissioning (or re-commissioning the hardware) as it's an easy time to do so.
Most people don't have an EEPROM burner with the software necessary to program the BIOS chip.
I have bricked a couple of motherboards from this - and generally the manufacturer will charge you - for a new BIOS chip (with the latest BIOS installed). 1) If you dont want to be afraid of updating your BIOS, or you bricked your laptop and don't want to pay - to a greedy manufacturer for basically nothing, I recommend that you buy USB SPI flasher SOIC-8 test clip (which cost is less than from China) So that if you bricked your laptop you can tear down your laptop and use these tools: attach SOIC-8 test clip to BIOS flash chip on a motherboard, test clip connects to USB SPI flasher, which is plugged in to other computer.
We also have no fallback (like we do for os/kernel) if its a bad firmware.
Hi guys, obvious question: how to properly update BIOS on our G-series notebooks?
Updating the BIOS carries the inherit risk of bricking the BIOS (most companies say that there is a 4-8% chance of this happening), so you should only do it if there is something that is needed...(functionality and/or hardware issues).
Updating the operating system and programs can cause OS problems - but you can fix that by a format/reinstall of the OS.
That other computer, after the installation of necessary driver and flashing program, can either read binary images of BIOS stored in this BIOS chip, or write your own BIOS image that you have to that BIOS chip.
Basically all these "repair services" are ripping off people because people are stupid and dont know how to fix their computers for themselves...
