I own an acer aspire 1652WLMi which contain ATI MObility RADEON X300 PCI-Express. Yesterday i have seen a new BIOS update for this system and i updated it using a file called "3A45 for ATI M22, M24 and M26" but unfortunately it was the wrong file. Now the laptop is Dead. No boot, no Post screen nothing. When i press the power button, only the black screen on laptop. Nothing comes up. Is there any way i can recover from this disaster or any way to flash with the old BIOS?
