Inspiron 11-3147 A09 bios update - slow post

Jump to solution

Has anyone else noticed that after the A09 bios update to your 11-3147 it takes way longer to boot up? It takes on average 15 seconds of staring at the Dell logo before Windows 10 starts to boot. I installed an SSD drive once It gets to the point of the OS booting it's lightning fast...just the bios post seems exceptionally slow. I'll try reinstalling the previous bios to confirm. I'm just wondering if anyone else has had this happen also. I also have an 11-3148 and there was a bios update for it on the same day. It didn't affect it's boot speed at all and in fact seemed to cure the "plugged in not charging" issue that it had.

I am using a factory installed HDD and Windows 8.1. After installing A09, the Dell logo stays about 10 second. I switch back to A07, and it is fast again.

By the way, what was your previous BIOS version and which SSD are you using?

I'm using a Samsung Evo 850 256Gb.

Here's an update to this strange story: Yesterday I reverted back to A07 bios. bios went in all fine but then can't boot into windows. It doesn't see my drive. it does in the bios but not during post apparently. All boot and drive settings look the same as they were before. Tried a repair install of 10 which actually worked for me this time (previously I've only had failures for some reason). It finishes and gives me a log file of the apps and such it killed in the process. Mostly just the Dell Apps which is no big deal. Rebooted and once again boot times are nice and speedy as I was hoping. And that's not all folks! To top it all off, it now sleeps properly instead of just shutting down like I was whining about in my last post. Bizarre to say the least. This was my last ditch effort. If this had failed I was going back to the dreaded 8.1. Used it all evening as I normally would and it's working flawlessly. Only thing I notice of any mention is the battery will not show 100% charge which is what the A09 bios update fixed. No biggie. It says 99% and I know it's fully charged. It really makes me wonder how much the guys at Dell check stuff out before it's released. Seems like every computer guy that's worked for my company is the same way....fix one bug but neglect to check if the fix affected anything else and walk away.

thank you, thank you!  This has been driving me nuts since running Dell "system detect" and driver updates after the latest Window 10 update.  I know better, I never install a BIOS update without researching first, but that's what I get for being in a hurry.  Smiley Sad   Losing Sleep mode on a tablet like this is very frustrating, and while changing the behavior of closing the lid to hibernate instead of sleep was a work-around, it still bugged me that I couldn't use sleep mode at all, because the dang thing wouldn't wake up!  (kinda like my middle son).

Thank you for saving me a call to Dell Support, that would NOT have gone well.  <grin>

I was able to skip the repair install by kicking it into Safe Mode when the first boot failed (same error, no boot device) but once it went into Safe Mode and I rebooted again, it came up perfectly.  So far, so good with waking from sleep as well.  Smiley Happy

Hello, everyone.

I have, indeed, noticed a much longer boot time. I figured out that it was a BIOS update because of how long the Dell logo stays without the Windows 10 wheel. Anyways, I'm reading that you actually have to revert back to A07 BIOS? You're even skipping A08? That's pretty crazy. I guess this really bothers me, but I can live it with it as long as I don't run into any other problems. Did anyone else notice other issues with A09 BIOS update? Ideally, Dell will fix this, but I'm not really counting on a quick fix any time soon. Your thoughts are deeply appreciated!

Maybe I went back to A08 and not A07. I'll have to take a look and see. I just remember it was working fine then after that last bios update on December 15 which is A09 it got slow on boot like you're experiencing. Worked fine otherwise. My other computer which is the 11-3148, has had several bios revisions and all but the original release of A00 cause the battery plugged in not charging message. I just emailed Dell about it but since the 1 year warranty period is up they won't help me with it. Typical! At any rate it seems to be fine with the old bios so I'll just keep using it and try any new releases that come out. Not sure why I bought these things. I have to work on our fleet of Dells at work and they are a total hassle with regards to drivers. Well these were just the best bang for the buck that I could find. Work okay once the bugs are worked out.

New A09 BIOS has been released yesterday.

Version number is still A09, but release date is 2/2/2016. Previous A09 was at 12/15/2015.

I hope this version really fixed the issue.

If you install it let me know how it works. They've released several new drivers lately too. I updated everything on my 3148 and was actually able to install Win10 1511 finally. Previously It would hang at post with that version which turned out to be the touchpad driver of all things.

DO NOT install new A09. It makes same issue. I think new A09 (released 2/2/2016) is as same as old A09(released 12/15/2015)

@JUSTICE37 That is correct. I still get the slow boot with the latest A9 BIOS update.
