    There are allot of community posts on this bios repair for your laptop, this laptop is an old Aspire and you can also download its SG readily on the web "Aspire 5349, 5749 & 5749Z" and then look up "Crisis Disk Recovery" page 2-28. Also, I don't take any responsibility for what you do wrong as this needs to be done by an experienced tech or someone that has experience so be careful! If you can't recover the BIOS and your bios chip is damaged then you will have to get a tech that has all the tools to replace the bios chip.

    Thank you. I have changed the bios chip but there's no signs of power.

    Have you checked to make sure the button is doing what it should? You should no connection until the button is pressed and the button should lose connection as soon as it's released.
