    Re: Pangolin Value: No Display (Screen? Battery?)

    Quick update - my laptop works fine when plugged into my external monitor. I didn't see the Ubuntu splash screen or 'loading' animation (that orange bar) or the System 76 bios screen in fact, but saw my logon screen after a few moments. No problems using the laptop after logging in.

    Haven't tried the memory cards yet - will let you know what (if any) difference that makes...

    Jozza The Wick,

    Try shining a flashlight at an acute angle into the screen -- you might be able to see very faint graphics. If this is the case, your backlight is probably dead.

    The fact that the first thing that shows up on the external monitor is the login screen indicates that your computer can see the built-in monitor -- it is switching to dual-monitor display at that point.

    Wow, phyzome, you're good

    When I shine a flashlight on the monitor I can definitely see everything during bootup - the System76 logo, the GRUB menu and the loading animation.

    At the login screen on my external monitor I can use Ctrl-Alt-F1 to switch to a terminal, and then see the text login prompt (with the help of the flashlight) on the laptop.

    I noticed one of the hotkeys should turn the LED on and off, according to the manual (Fn-F2) but it doesn't seem to do anything.

    So - what's the next step? How do I go about getting the backlight fixed?

    Thomas - any suggestions?

    Thanks again, Phyzome!

    If your backlight isn't broken chances are that the connection to the motherboard is flaky or loose. Either way, I suspect this is definitely a hardware problem. Wait for someone from System76 to confirm this.

    Jozza The Wick:

    email us at support...at...system76...dot...com

    This definitely sounds like a broken backlight.
