There is no need for an incremental update. You should only update your BIOS if the new version contains an improvement you need. If you see that, enable it. Then save the changes and reboot the system. Last edited by thork; at PM. It works the same way as if you are Updating your bios.
Just put the bios version you want on a USB stick, and use your flashback button. A botched update might be able to damage a motherboard, particularly if it is the wrong version, but in general, not really. A BIOS update could be a mismatch with the motherboard, rendering it partially or completely useless. Plug the notebook into an AC adapter.
Last reply by pcgeek11 Unsolved. Calla Lily 3 Zinc. Is it safe to downgrade BIOS? First, about downgrading BIOS, is it a safe thing to do? Not happy with this one due to high pitch sounds coming from the top right hand corner of the laptop. It's been suggested that I downgrade only a couple of revisions back, namely, to either A09 or A However, Ive been getting conflicting reports about the safety of downgrading. Some say that it's not done at all, others say that as long as it's only to downgrade back to a couple of previous versions, then risks are not as high as going all the way back to a really early version, such as A03 etc.
The risks, I'm told, is in the performance of hard disks. Apparently, if you downgrade to a really early version such as A03, then problems will arise, though I'm not sure what the exact problems are. Moreover, there are those who say that there is no procedure for downgrading and that it is never suggested to anyone to downgrade their BIOS. The notion that it becomes riskier as you downgrade back to a really early version of BIOS such as A03 baffles me, because in my case, prior to doing any kind of updating for BIOS on my laptop, I had version A03, and have not had any kind of improvements, enhancements done to my computer whatsoever.
I only added iTunes, Firefox, Thunderbird, plus software for a corded keyboard. Therefore, the claim that reverting to a really early version of BIOS such as A03 would pose a greter risk than reverting abck to A09 or A08 does not make sense, for my computer worked fine with A03, and I have not changed any of my hardware. My reason for upgrading is because Dell Support software popped up in the bottom right hand corner saying I needed to upgrade my BIOS to A08, so I did that, then discovered after that there was a critical update of A10, which I installed as well and which I have currently.
Another question I have is this: how do you know for sure that an upgrade or downgrade was successful? However, is it possible that even with a message saying that an update was successful, that there may be some glitch and that the BIOS was NOT updated properly? It should take around a minute, maybe 2 minutes. Skip to content Android Windows Linux Apple. Home » Other. Is it okay to downgrade BIOS? Like this post? Please share to your friends:.
