ASUS ROG Strix G15 not booting after Ubuntu install — black screen, keyboard lights on
Hi everyone,
I installed Ubuntu on my ASUS ROG Strix G15 yesterday. The installation finished normally and there were no errors or power cuts during the install.
Today the laptop suddenly went to a black screen. I forced it to shut down by holding the power button, but after restarting it only the keyboard lights and power light come on. The screen stays completely black, there is no ASUS logo, no startup sound, no fan spin, and the Caps Lock key does not respond.
I tried a long power-button reset, disconnecting the charger, opening the laptop, disconnecting the battery, and removing/reseating the RAM. After one EC reset the ASUS logo appeared once, but then the screen went blank again. Now it is back to showing only the keyboard lights and no display.
Does this sound like a BIOS/firmware issue, a motherboard problem, or something else? Since it does not even show the ASUS logo consistently, I’m worried it may be a hardware problem rather than Ubuntu itself.
Any advice would be appreciated.
