Hello, This is my first post on the MDL forums. I did latest bios update for my computer recently. I downloaded latest bios file on official Acer website then i ran the updater on windows. Update completed and computer was restarted. But no more splash the Acer screen. Then i sent my PC to the authorized repair center. They are repaired my BIOS. But the "serial number", "model" and "UUID" strings are blank on the setup menu. I searched the forum for restoring DMI data. I tried many method for this. But i can't restore them. I ran phlash16.exe on DOS. I tried to flash bios by using this command line: Code: phlash16.exe /c /mode=3 /r=3 /s /x /z /uuid /dps:[string] /dss:[string] BIOS.WPH And some commands like that. But this was not successful. Can you help me for restoring my DMI data?
