welcome.
My problem is that I failed power even when it is updated to bios and had no battery in it.
I made crisis mode operation with a CD, now starts but its screen and keyboard does not work so I use my monitor and another keyboard.
What else can I do to recover?
I have Acer Aspire 5742ZG-P613G32Mncc. Can not find any good bios for this laptop are many variations 5742ZG.
I would be grateful if someone would help me to fix your laptop without having to send it to a service.

If you can't find a recovery solution, you have to re-write next BIOS flashrom.
(Open bottom cover and find it)

Chip looks like a Winbond W25Q32 or W25X32.
Many programmer supports them.
(Your BIOS file is "...\BIOS_Acer_1.30_Windows\DOS\PEW71x64.fd".)
You can find easy low cost programmer.
But, chip is SMD type.
If you don't have soldering tool like a solder station(little expansive), "BIOS emulator"(find on ebay) is betther for you.

Which VGA do you have, nVidia or AMD? I think you flashed the wrong bios as there are 2 variants...
