Hello, I have an Extensa 2519 and it had a corrupted bios. I tried to flash with the first image of this post with an EZP2019+ programmer but it didn't work (power light on, fan on, black screen). So I tried to flash the second image (Acer ex2519 N15W4_Domino_BA 14285-1 working bios, mx25u6473f_8MB). It flashed and verified correctly but now the notebook just won't turn on. No power light, no fan, no nothing whatever I do (even with the previos bios). Any suggestion?
