Hi, I have problem with Acer VN7 571g laptop. Bios don't recognize hdd and cd-rom. Bios was updated to newest version. I tried connect HDD to other computer and he's working. In Bios show HDD model name: none. HDD cable is working, becouse HDD is spinning. I set Boot Mode to Legacy, but nothing. So what problem is in this laptop? Sorry for bad english.
