L14 - Display is Black (Not booting)

Hardware Librem 14
1

Good evening!

Got back from a work trip. Opened up my L14 and knew the battery was dead so left plugged into charge via USB-C charger. 6hrs later went to power on laptop but display is blank. When i press the power button i see the keyboard LEDs turn on then off, the toggle switches work, and the battery indicator light is white. Tried pressing and holding the power button for 15 seconds and then powering on. Nothing.

When on I did hear some coil whine from near the CPU on the machine. Other than that I have no idea what could be going on. I did though recently install L14 Bios version 30.

Thoughts?

Try reseating the battery, then turning on the laptop again.

3

Nada :confused: Left battery unplugged for a couple mins and nothing.

Try the reverse situation by removing the battery while powering the Librem 14 via AC or USB PD.

5

To confirm: Unplug battery and try to power on Via USB-C or AC?

6

Yes, we need to know if the battery is the cause of the issue or not.

7

okay.

Tried powering on via USB-C … Nothing. Don’t have AC brick with my at the moment to test.

Okay, once you have access to the AC power adapter, test it against the Librem 14 and let us know the results.

Interesting thing i discovered… upon inspection one of the cells is bloated so… battery looks more like a probability?

Maybe, in that case the battery should remain separated until you know whether or not the AC power adapter works with the Librem 14. Once we have those results, I can suggest a plan of action for your circumstances at that point.

Morning!

Tested with battery unplugged and AC brick plugged in. No screen. It does look like its trying to power on, just the display is black.

13

Without battery plugged-in it can boot 30 sec after pushing the power button. Also try switching sides of USB-C if you use it for power.

14

Tried both USB-C and AC Power brick… nothing…

15

Yea, will the all the troubleshooting… no display
