    Latest BIOS version is 1.17 dated 2019/06/12. If you tried to install another BIOS version, not for your model, try to boot to BIOS with F2 and reset BIOS to factory defaults with F9 in Bios, save settings on exit. If you cannot boot to BIOS anymore open the laptop and reset the CMOS module: Disconnect the battery cable from the motherboard. Locate the CMOS module (with 2 twisted wires Red and Black) and remove the coin battery. Shorten the +/- contacts inside the CMOS capsule for 2 seconds with a bended paperclip and put the coin battery back with the + sign facing up, close the CMOS capsule. Reconnect the battery, close the laptop and try to boot. If still no luck I recommend bringing the laptop to a reputable PC repair shop.

    can you provide in-depth tutorial? . Im also tried flash bios (rename to "HadesSX64") using Crisis (fn+esc and power), then saw power light flashing and system rebooting but display still blank. Thanks for your answer
