Time and date correct and charge to 80% set and saved.
Charged for 24 (26) hours
Started without ac connected.
Went through a sequence of black screen 17 seconds with power light ON
Then power light off 2 to 3 seconds
The ON and Framework logo
Booted.
Checked BIOS Time and date were wrong two days out and four hours out
Reset 80% battery charge
Reset time/date in Windows
booted and checked BIOS, new settings saved.
This is tedious on any PC, on a new top of the range PC it is unacceptable to have to do this regularly
(elsewhere I read that (3.07 BIOS update fixed the power on probs?)
I assume that GFW30.03.07 indicates I have the latest “3.07” BIOS ?
I will now NOT charge the PC but power on with no ac connected every day and see if the problem persists.
You need to run multiple bursts of high CPU load to flip from white to red/orange again. (It’s to do with that trickle charge scenario) You’ll see that the battery charging would toggle from 0.00w to a positive non-zero value.
Powered on ok checked BIOS and the changed settings are still there.
==========================================
Update from Framework where they suggested charging for 24 hours once a month to avoid loss of CMOS settings now that first 24 hour charge was complete.
NB As previously confirmed by Framework there is no way to check from within Windows on the voltage or charging status of the CMOS battery.
Re the “Intel” problem and general info (from Framework ! ) on the CMOS battery, 24 hour charging leaving the Laptop unused for long periods etc. etc. this is a MUST TO READ
Read the Jason_Dagless post, it starts with “I got a long reply from Framework to my short question -”
EVERYONE with a CMOS battery problem should read this.
Good luck with that the RTC|CMOS battery is designed to supply 30µA/Hr which means the battery could last 24 days
Given there is some concern that the CMOS and CPU are draining the battery at a hight rate you may not get 30 days as that equates to 24µA/Hr
If your system is running and not taking 24µA/Hr then you may reach 30 days as there is a report of someone reaching that.
Howvere should the RTC/CMOS battery drop below 2.5V it will need pulling and allowed to recover maybe to 2.7V before you can start the laptop even with external power connected.
Not something I’m likely to try, luckily as I couldn’t stop using it for a day
I can live with taking it apart once (it’s a DIY machine anyway) that allows me to measure the voltage etc. too.
I read somewhere her that there is a higher capacity rechargeable battery too? In which case I could replace the existing one? Do Framework supply this, I will look in a moment.
PS I guess the discharge rate does not vary with use, but the CMOS battery does get a little charge when I have to connect the p/s as I did yesterday. This could slightly extend the life (ok JUST) to beyond the 24 days, 25 maybe?
I don’t think there is the standard capacity is 17mAh
The size does matter the ML 1220 means it’s 12mm (12.5) diameter and 2.0mm thick so you can’t really put a bigger battery in the holder and I haven’t seen a larger capacity battery.
Even if there is a higher capacity of that size then the charging charactersitics may not match with what the motherboard supplies.
The current KTS make is from the same manufacturer of Panasonic…
The only alternative is the Maxcell version which states 18mAh of capacity.
You may like to see it’s spec, but I don’t think it’s worth swapping to it.
If you connect the power supply then it will, and that is the recommeded action that Framework suggests if the laptop is not going to be used for some weeks ~ leave it plugged in.
Whereas that may/should work according to Framework I hate to imagine what power the adapter uses 25/7 for 30 days just being basically idle.
It only has to supply 1mA, well less as the CMOS battery will not stay discharged after a day so we maybe talking about supply a max of 30µA continuously.
Voltage adapter are not very efficient and often have a draw of much higher than that when there is no load, so maybe 10 times more electricity is being consumed in the adapter than is getting to the CMOS battery. Oh and of course there’s the motherboard circuitry at work all the time.
I’m not concerned that it may ‘waste’ 99% of the electricity, I’m not an environmental freak of that nature, but it does cause me to raise my eyebrows.
Typical mains unit will use 200mW to provide 3mW to the CMOS when it is completely dead and 200mW when charged after 24 hours to provide 3v x 30µA i.e. 1mW
I know this thread has veered into CMOS battery issue but there is one thing I would like to note my case, that seems slightly different.
My build is similar DIY build 11th gen, came with Bios v3.7
The power on issue happened to me only once. I had taken the new laptop with me and had to work from my car for a bit. To test if the car usb port could charge the laptop, I plugged it in to the USB C port (top right port). It started charging so I disconnected it and continued on battery. After a while, I closed the lid and drove back (maybe an hour). Laptop was on the backseat.
When I came home and opened the lid, the laptop didn’t power on. No lights nothing.
After a frenetic search, first forum article I found said plug in two power supplies, and I tried that, and I believe that did the trick. Since then I’ve left the laptop on charger with battery set to 80% most of the time… however I’ve left it on the bedside on a couple of occasions and it hasn’t had the power on issue next day morning.
It could be that was the first or second day of usage and the cmos battery hadn’t charged fully and hence it went bust (and the low power USB C connection didn’t have anything to do with it). I guess I’ll find out soon as I am expecting a far bit of “off charger” use in the next three weeks.
Could be an unseated cable but then I’ve taken in in a backpack walked about, been to friends, since then and it hasn’t baulked. So unlikely to be a mechanical issue.
