Re: Acer aspire E1-521 24PQ bios needed

try the bios from post # 12 if you have E5-521.

Hi there,

Thanks for the help. I try this but now I have a problem (I don't if was cause by me).

By steps:
- I use the CH341A programmer and the software 1.41.
- I think that I do every steps: Read, Verify, Erase, Read, Auto (write & verify)
- After I assembly the MB to screen, ac power & power botton.

The problem:
- Don't turn on
- If I put the battery (with the ac power connected) the led of chargind don't came on
- If I press the power button, the leds came on, but still no image (and now I have lower charge on battery - the battery led came on)

Can be the EC firmware? Or KB9012 file? I don't tuch this file because I don't no how to do it.

Can I get any help, for this. I have have to rescue this laptop.

Best Wishes
