After assembling my FW16 DIY I plugged it in, installed Linux, and used it for several hours. During this period the battery charged just fine. The next day I woke it from suspend to find the battery very low, and no charging was happening despite being plugged in. I tried several chargers in both expansion ports 1 and 4 (the ones indicated to support charging) all with the same result: the associated LED would light up amber briefly, then shut off, and the OS would not recognize any power flowing. Eventually the laptop shut off due to low battery. Here’s where things get more odd: at this point plugging in a USB C cable resulted in the amber charge LED lighting up solid for several hours, at which point it turned off entirely and would not light up again at all when unplugging/replugging the device. Turning the device on, however, resulted in the original behavior of the LED lighting briefly before turning off, and when booted showed that the batter was still very low on charge, so much so that the laptop shut off on its own again shortly afterwards. This again resulted in a solid amber light for a few hours, but no apparent change to battery status, as attempting to boot now results in the screen lighting up, a very short view of the BIOS password input screen, and then the device losing power.
So far I’ve tried:
- Both charging-capable expansion ports, 1 and 4, with and without expansion cards in them
- Two high-power USB C cables that I use to charge other laptops, and a low-power USB A-to-C cable overnight
- Removing the battery for a few minutes and then reassembling the laptop
None have changed any of the observed behavior. I’ll restate that charging was working upon receipt of the device, and even after charging stopped working the device remained able to discharge power from the battery to operate.
