У меня есть проблема, мы VPCEB1B1E (PCG71212M), электрические огни прийти на цели ничего экране. Через 20 секунд вентилятор ездить быстро.
Это может быть проблема BIOS?

Yes, maybe the BIOS. But you have to check not only the firmware, but the flash. On Insyde H2O on both of these problems are seen.
