I cannot update bios because of missing battery, can anyone help, please?

edit:some more info-> Dell Inspiron 3551 laptops have this thing that for a regular bios update via .exe file the AC should be plugged in AND the battery should be at least 15% or 20% (as i ve heard from extensive googling). As i don't have a working battery ( battery dead) i get an error message like this:
I have tried many solutions .. /forceit, installed windowsPE, i can't even remember any more, it's been a grudge match, so, i kindly ask someone to, maybe mod the bios installer so it wouldn't check for the battery? I m so noob with hexeditor and in general...

Hi friend,
sure the Battery control can edit by AMIBCP Aptio V :

If your CPU is intel you can use fptw tool to make a bios backup and reflash back after edit, if not , then use Afuwin or Afudos.
Regards

P.S. normally the Battery check is into EC , but may be here is into bios.

Thanks a lot for Your answer and help! I will get right into it!

Happy 1st of May!

EDIT 1:
Right away i notice that both guides You linked need USB Flash, but i don't have one. What about fptw tool? I do have Intel. Right now i am googling fptw tool...

EDIT 2:
looks like it does need USB flash, does it?

When reading "Intel (Converged Security) Management Engine:Drivers, Firmware and Tools" which I found in @Fernando 's linked thread, section "Flash Programming Tool (FPT)" , I did not find "Motherboard > Intel ME > Intel ME Version" of my system, at which time i started questioning, if my CPU is actually Intel. My HWiNFO64 page:

As You see, under CPU I have Intel Pentium N3450, yet under System > System Manufacturer (also Mainboard > Mainboard Manufacturer) I have Dell Inc., and... no Intel ME Version here anywhere, so I guess, I don't have Intel CPU...? Maybe... It's the motherboard manufacturer that determines what's what?

Since I did not find Intel ME Version, I am thinking Flash Programming Tool (FPT) is not viable to flash my BIOS, right?

Continuing on=>

Through downloading and installing UBU tool from the same thread (1st post, section "Guide for ASRock mainboardswith an AMI Aptio UEFI BIOS") (BIG Thank You to @Fernando for making it easier for newbies like me), I have found that my Bios Platform is AMI Aptio 5

..which is great, because 1) i did not know that 2) I do have Aptio V Firmware Update Utility!

But, since I don't have a working battery (the culprit of my problem), I am guessing I should run Aptio V Firmware Update Utility through command prompt to enable "/JBC" parameter which interprets as "Don't Check AC adapter and battery", correctomundo? (I did not find an option to disable battery check in GUI version of AfuWin64 (AFUWINGUIx64.EXE))
Yet another problem arises => when trying to open AFUDOS.exe, I get error like this:

When trying to Run as Administrator, error like this:

When opening AFUWINx64.EXE, it opens and closes immediately, when Running as Administrator i get a window like this:

I cannot type any command here, any key i press gives me more info about commands (which i can't use, grr), 2 more times until the window closes.

That's how far I've got. Any ideas?

Thanks for Your help, I guess I will be using this forum more to unlock my BIOS later when(gotta believe) I deal with this "Cannot update BIOS because of missing battery" issue , since this forum is poppin'

I can't find the Intel ME version, i might have deleted the supporting drivers at some point when trying to maximize performance by deleting from the app directory. ( I know...)

And now i don't know which drivers to install
Can't I use UBU Tool to flash my BIOS? Does it have a "Disable Battery Check" option somewhere, somehow?

EDIT: just FYI, i don't have a working battery and I don't have a USB stick ( I know...). or maybe another utility can do the trick?
Thank You

Hi, @RefleXx !
How are things going? If you just need to update the BIOS, then I can help you. I already did the same for DELL L702X (see attachments). It's simple, just let me know you're ready.

@Sweet Kitten

Thanks, I've been trying to update BIOS for a couple of weeks now, would be great if You could help!

What info or files do You need from my system, if any? But You will really have to Eli5 because of my newbness. Thanks!

EDIT: Also I am preety sure my AC Adapter is not original (along with the missing battery issue). I hope that cannot brick my system...

@Fernando
Got it, dude, thanks. I guess the flashing part is my main concern for now. Now after I see what does the latest BIOS version offer, I might decide to update it, to unlock some extra features for optimizing my machine. Am I correct in this terminology?

@Sweet Kitten

that was quick, Thank You!

Ok let me reboot and try to update BIOS with GSet Bios Flash Update, since I have heard it is the safest way. (Really don't want to brick anything, this is my first time. Nerves.. )
EDIT: Actually what am I talking about, I cannot update from GSet Bios Flash Update because it knows I don't have a battery. I will just do it from Windows OS. Wish me luck. Thanks!


EDIT: SUCCESS!!! Thank You @Sweet Kitten

Now let me dive into my latest BIOS settings so I can Optimize my System's Performance, which has been subpar imho - cannot watch twitch.tv on 1080p resolution, CPU goes to 100% and every 3-5 seconds i get a lag spike. No bueno. Gotta find a solution, hopefully in my latest bios version A07 for Dell Inspiron 3551.

Good day, gents!


EDIT 2: lol it is the same. completely the same! that's a turn... what should i do now? I guess I do need to mod the BIOS for additional parameters to be available...

Master @Sweet Kitten could You, by any chance, do something like that? I am too newb.

@RefleXx: The tool named "UEFI BIOS Updater" (UBU) can update UEFI BIOSes, but not flash them.
