I have a Batch 8 Framework Performance model (i7-1165G7) which came with 3.07 BIOS installed and which is still running Win 10 Home.
I didn’t fancy trying the procedure given in the Framework Knowledgebase (My Framework Laptop (Intel 11th Gen Intel® Core™) is not powering on), nor the other recommendations in various other threads, and none of the suggested explanations were definitive so I experimented.
I charged the laptop up to 100% using the Framework charger. I then disconnected it, powered down and disconnected it from the charger (2022-07-31).
I then left it disconnected from the charger for over 24 hours (varying from 24 hours and 11 minutes to 33 hours and 32 minutes) before trying to power up again. I did this for 17 days (from 2022-08-01 to 2022-08-17) before it failed to power up.
The on button was not lit up so I connected it to the Framework charger – the button lit up – I pressed it and disconnected the laptop from the Framework charger. It booted up (2022-08-18 at 0:58) – battery showing 60% without time remaining detail – date and time showing as 2022–08–17 and 0:24. (I had previously powered it down on 2022-08-17 at 0:23 when the battery was showing 62% with 6 hours 33 minutes remaining.)
I carried on experimenting until 2022-09-16 before I charged it up again.
I didn’t try leaving it for 24+ hours again after I recharged it so I don’t know whether there is a specific battery level before it fails to boot. At the penultimate shutdown before it failed to boot when disconnected from a power supply the battery was showing 64% so if there is a specific battery level it’s somewhere between 62% and 64%.
Connecting the laptop to a power supply until the light on the side flashed was sufficient to allow the laptop to power up again – even when immediately disconnected before pressing the on button. This was true whether I used the Framework charger or a USB-C to USB-A cable (Anker USB C Charger Cable, PowerLine+ USB–C to USB 3.0 charger cable (3ft/0.9m), High Durability Type C Braided Charging Cable; and an oneo Endurance USB–C Data Charging Cable – 2M) connected to a USB 3 port on a desktop computer. I didn’t try connecting to a USB 2 port.
The time remaining figures would change (up and down) frequently – even when the battery %age didn’t change. Also the date and time would show details a little later than the date/time that the laptop had been shut down. Windows reported multiple failures when a manual date/time sync was tried even though internet access was OK. I shut the laptop down after 5 minutes of sync fails.
After shutting the laptop down it would then reboot properly while still disconnected from a power source. The date and time would show correct details after the reboot. The laptop would reboot again after a further shutdown if done soon enough. It rebooted after a delay of 4 hours and 22 minutes but failed to do so after a delay of 4 hours and 38 minutes so if there is a specific maximum delay it would appear to be between these two values.
I can’t say that what I found will be true in all cases but neither a cable nor a charger is particularly heavy or bulky so I’ll just pack one or both if it looks like failing to boot may be a problem when I take my laptop away from home.
