Most likely the RTC (real time clock) battery is not holding a charge anymore?
The first gen mainboards only charged the RTC battery via the charger so if you didnt plug in the laptop for some time it wouldn’t boot anymore even if the main battery had charge because the laptop does not boot with a dead RTC battery
You can either replace the RTC battery yourself or framework can send an RTC battery replacement for free that uses the main battery as the RTC battery but it does require you to solder a single wire to the mainboard








You can easily change the RTC coin cell battery with no soldering
Soldering only comes in to play if you want to get rid of the coin cell all together
With some laptop usage/charging patterns the coin cell would empty to dead easily and I would not hold a charge well anymore after that. So even if replace the coin cell, your usage pattern could kill the next coin cell as fast as the previous one. Hence the need/want for the battery bypass
