Acer 5633wlmi from slic 2.0 to slic 2.1 My laptop in a bios update has freeze and stop working (it even don´t power up). Since then i can´t recover because it wont power, so i give it to repair. Only today they have send the laptop with the original bios from acer. Since there are many models that use the same motherboard they have replaced the 5630 to a 5610Z. I update the bios made to me by Busykid508 with dell slic 2.1 (dont work). I have use this bios made to bubuxp and i second that it work very well and has activated windows 7 oem ultimate X64. Once again sorry for this long delay to give feedback. Continue the great work.
