Fair, I definitely recommend getting the official charger if possible. In my case I moved to a country that Framework doesn’t ship to and the charger was about $20 cheaper than it is now when I bought it.
Given the third-party USB PD tester (which shows voltage, amperage and watts, min, max and current) has never shown anything out of spec, I personally feel fine using it and I expect the issues I am experiencing are on Framework’s side. I’m happy to be proven wrong though and will help in any way I can.
I wonder how many amps can FW16’s internal circuitry handle sustained, considering that I know of at least 2 chargers now that can do 48V/6.5A.
I wish they exposed some EC settings in more accessible way, like changing the max power draw from charger (they limit it to 85%{i don’t remember exactly} of chargers rated power).
It’s limited to 90%. The device itself is rated for 240W, so I would assume it’s capable of sustaining 5A, but my assumptions about a 240W PSU providing 240W ended up being unfounded. I’d be curious if those other devices you know of are able to reliably provide an actual 240W to the Framework.
The computer limits the current to 90%, not the charger. If you adjust the EC to draw 240W it’ll draw 240W. The Framework 240W PD EPR charger can reliably provide 240W
Yeah, I run ECTool to override the charge limit. I think you’re right, For some reason I had been attributing the change to the PSU logic rather than the FW16’s logic, but the way you’ve phrased it makes more sense. Good callout
Well the problem is that it’s 90% of negotiated PD spec, so even if the charger can provide 6.5A (like the Delta’s 240W charger) the FW16 will not concider it as an option.
Well I have a dock officially capable of 48/6.25, but all I get in logs is:
Updating charger with EPR correction: ma 10260
CL: p0 s0 i5000 v48000
Similar to a 165w 28/5.8 that I used to have, which makes sense, because 5A+ is out of PD spec, so both the laptop has no use to implement the code nor the charger manufacturer to reveal their secret handshake to expose more than 5 amps.
It has problems with docks. My dock supplies 100w, but the laptop will only accept that if I had it powered off for a while to reset the EC it whatever. Most the time it completely ignores charging from the dock and I have to connect another charger.
I was coding on the laptop, and suddenly all lights went off. I unplugged every consumer in the area, replaced with a new fuse, connected the brick to the power outlet. All lights went black again, and I needed to replace a new fuse.
So, I need a new brick to use for my laptop, I am not sure what quality this 240w brick is made of, is there any recommended quality brands?
It sounds to me that either Live is shorted to Neutral or Live/Neutral is shorted to Earth.
Don’t plug the 240w brick in any more. Is it a Framework provided brick?
If you have a test meter, I would be interested to find out if Live is shorted to Neutral or shorted to earth.
To test, do not have the brick plugged into the wall. Just place the test meter on the brick side cable prongs while they are unplugged.
The reason I am asking, is because if it is shorting to earth, it might be a manufacturing fault, and not have the correct spec of X and Y capacitors.
Hmm, I measured, and there is no short circuit between the prongs. Maybe there is some solid state switch inside that is shortcutting when powered on, speculation, I am far from knowledgeable.
And yes, it is the Framework 240W adapter I got with the computer in december.
Edit: Just in case, I measure the power cable aswell, even though there is low chance that is the culprit.
Ok, so not a manufacturing fault then.
Contact FW support via their web page support form. They should be able to resolve the problem.
Note: I am just another user like you.
What was your issue? I just got my 5070 and 2nd gen display for my 7840hs and the 240w doesn’t keep from draining even when using the balanced profile while gaming. But mine is entirely showing as not charging while being at 77% when looking at hwinfo64 and no longer gaming. It’s being super weird
I have been thinking about the problem.
Problem: the CPU/GPU can peak draw more than 240W, so it draws the extra from the battery. This causes the battery to discharge a bit during gaming.
When the charge level drops below a particular amount, it starts charging the battery at the max rate the battery wishes. Pulling power away from the CPU/GPU.
Might there be a way to pull 240W from the power adapter, use whatever the CPU/GPU needs at that point, and pipe any leftover into charging the battery.
This would then cause zero power problems for gaming.
I don’t know if the charging chip can do it, but at least an idea for future gaming laptops.
