[passete]

Hello Guys,
I have this mobo : DA0ZQ1MB8D0 Rev. D
PN : P604G32MNKS

Black Sceen, No Usb, keyboard ....
Light Reflow (Not used My Rework Station), still black ...
Maybe it's time to test a New Bios Dump ?
Anyone with a bios for this Mobo ?

Thanks

Re: Acer 4820TZG Black Screen

vous devez laisser le circuit de bios a cotè et ne pas le vider
et utiliser un autre circuit et le faire vider et ensuite le flasher
toujours je travail avec cette methode
c'est mieux pour garder le vrais fichier

i Hate Acer, i really don't understand how people can like this "Trash" ...
I'm goging to reball the GPU, even if i already know the result.
Changed ram, cpu (intel with graphics), tried 2 different bios and EC's ... same result, turns ON, but Nothing !
Ohh I love Acer !

@rida, merci mon frere.

Vamos até ao fim tugas

After this new EC bios, Fan starts spinning crazy after 10 seconds.
Wrong EC dump ?

Re: Acer 4820TZG Black Screen

@ala borbe as fixed my corrupted bios (main and ec).
Flashed main bios, pc booted and no more fan spinning crazy, turned off assembled the pc, turned on, and again black screen ....
Which bios cause the fan spinning fast, main or ec ?

EDIT: Removed the Top Screws (Under the keyboard) and it's working ...

Re: Acer 4820TZG Black Screen

SOLVED, it was a screw on a wrong "hole".
I'm sharing the files used to fix this Netbook
1 - Unlocked Bios 1.25 (install directly from Windows)
2 - My Fixed main Bios by @ala borbe
3 - Ec Bios found on the web

Use those files if you mobo is the same, check first post

Re: Acer 4820TZG Black Screen

main bios was the problem
as for screws... put some tape over motherboard, your top cover (palm rest) touches and shorts motherboard

take that black tape or kepton tape and sick over board and you will be fine

For me, it doesnt work for 4820TG any of these files.
Works this for me only this one for 5820TG.
