Comment 65 for bug 1040557

Same here. I'm installed sucessfully Ubuntu 10.04 x86 in the SAMSUNG 530U3C and works fine. But when I tried to install the 64 bits version, I assumed that enabling the UEFI boot from bios will upgrade the performance, but the Laptop hanged up in black screen and never start over again. Turn the power button On, the power light blink, then the HDD light and thats all. It's impossible to switch any option of the BIOS due to is impossible to see it. The shop changed me the laptop for a new one because I bought it only15 days ago. I'm afraid to try out again the Ubuntu 12.10 amd 64 with the UEFI boot disable and this episode shows up again.
