A casual story ...

a bios of a friend of mine is stuck ....
from a fail update through Os Windows 10 by AMI ( gui mode ).

About the concerned computer : https://www.packardbell.com/pb/fr/FR/content/download
SN : 23502301192
Brand : Packard-Bell
Model/number : imedia s2110

I pick the bios update from packard-bell url :
so the chosen version is : P11-B3.CAP

one the update pass, the computer reboot ... and then 'black screen' - no more display.

the mother-board looks on, and beep when I pull off ram.
it avoid bios access...

I realize cmos reset ( with clear position ), then button battery out ...

one thing I  note , by some try the fan are high speed ( like in fail safe mode/ or on a new fresh cmos setup ... )
other thing : the Hdd?/cpu? light sometimes is ON until I turn off the computer, but nothing else..
or this light seems to 'works' but 20 seconds and then nothing...
I heard Hdd access too, it's a noise I recognize.

The POST don't get over..

To comment about firm answer('s) :
its money or nothing ... and not costless ( 150 euros... ) , buying a new computer is not so far ....
no relevant ways or accurates answers on acer forum ( packard bell is now acer.. )..
and a crowd of 'solutions', do but don't do that.. keystrokes but the other one, but after 3 reboot. 

As I'm IT worker, but not hardware enough,
I have to crawl lots of ressources and docs.

So, in front of amibios / afudos / afuwinx64 ...
I really don't know which one I need, as I can't confim my USB key is read.

I did a usb boot key ( free dos in ), format fat32. with script afudos, then afuminx64 and a batch with amibios advise... but no more display, no more bios.

I don't know if I need a keys combination to launch the usb reading ...at startup.
I call few It friends , I heard often "only firm can do". ( I don't trust that ... )

Updating a bios is a task I do 1 time a year... computers are globally ok. But it's deep learning for me every time ...

I don't know what you can do for me, if you have an answer...
I don't know If you need support, or a have pay solutions.
