A call on 240w adapter

Yeah, we need a BIOS update. The various 13s had many updates since launch, we’re stuck with the faulty 3.05… :frowning:

Not that any of those fixed these particular issues on the 13 jet either.

Well, the Prime Day deal got me. I guess I’ll be trying to find out if the UGreen 240W charger exhibits the same behavior as the Delta charger.

I played rdr2 without problems with the ugreen 500W, seemed fine to me… But I have no idea how to check gpu wattage. There was 1 problem, when the laptop ticked from 89 to 90 percent, the screen slowed to 1fps.needed to force restart. But since, the battery is at 90 percent, and seems to be stable.

Please le us know!

Will do. It’s supposed to be here today. I’ll try to do some testing on it in the next day or two to see if any oddities show up for me.

It’s definitely a chungus.

Do you have a dgpu in your 16? If so, please test gaming and confirm whether it has the same jitter and power issue the Delta one “causes”.

I had that happen today. Same charger, dGPU, in RDR2. I “fixed” it by limiting CPU to 3GHz (ryzen 9 variant).

I do have the dGPU. That is my intention, though it seems like @CMDR_unematti is having issues. So we’ll see.

That thing is like the size of a full minipc

I can’t say for sure, but I’m 99% sure it’s larger than one of the new M4 Mac Minis, lol.

Here is another 240W charger:

Reading the specs of that HKY 240W charger it mentions:
"The 240w charger includes protections against overcurrent, overvoltage, and short circuits, enhancing its reliability in various operating conditions. It also supports a peak load capacity, allowing it to handle power surges up to twice its rated load for short durations. This feature is particularly beneficial for devices with high inrush currents at startup. "

I think a problem with the USB PD spec is it does not allow the charger to tell the laptop about these “peak load and power surges” capability.
If it did, the laptop charger chip could correctly set the short and long current draw limits, meaning that the laptop could pull more peaks from the charger, instead of draw the peaks from the laptop battery.

This is something we have learnt from the thread:

Mind you, the info about that charger also mentions the 5A limit, so how exactly anything can draw higher peak currents is unclear, unless more that 5A is permitted for peaks.

As always, better look up the public spec before thinking it does not or cannot do sth. Because this


is already part of the regular source capabilities.

And there are even more detailed extensions in Extended Source Capabilities.

As long as it still provides sustained 140W that should not matter, correct? It would just be a bit more robustness.

New to the forums here and not super technically advanced but I certainly dabble and try to learn along the way. I recently ordered a Delta 240w charger as FW had said it was capable of using one and we are all obviously experiencing the discharge issue during full loads. Was hoping this was no longer going to be the case with this charger but what I am reading doesnt seem to be resolved. I’m running Win11 with mine. Any recommendations when mine arrives? I am also waiting for my PTM 7958 swap kit from liquid metal due to the throttling issues that many have experienced and looking forward to new performace from that. Hope to see some better results.

A 240W PSU is better than a 180W PSU.
We have found that the FW16 can peak at over 450W for very short periods.
The charger IC is set, by the EC, to limit the current it can draw from the PSU, so for the 240W PSU, it limits it to about a figure slightly below 240W.
If the CPU wishes to draw a peak of 450W, it takes the excess from the battery.
But, if the EC had taken account of the peak that the PSU could do. It might be able to peak to 480W for short periods. It could have programmed the charger IC to handle the peaks, and therefore not pull from the battery.
I have a FW16 and a 180W charger. I have not fully decoded the USB PD CC messages from the 180W charger, but if some of them also mention the peaks it can handle, as per a hint from @Ray519, then we might be able to coax the FW16 charger IC to use than information and thus draw from the battery even less.
My decoder is a bit ad-hoc. I capture the trace from an oscilloscope into a .csv file.
I then have written a program to decode that to USB PD CC messages.
Eventually, I will probably add this decode to https://www.ngscopeclient.org/

Framework should hire you. Then maybe we would get an updated firmware to resolve these issues.

I stumbled upon a few different posts across the community and even reddit where folks were saying they were running into issues with the 240w (Delta) creating massive studders in performance compared to the 180 from FW and this just boggled my mind. I could understand it wouldnt be 100% efficient, if I recall I think I read somewhere it was just under 90% (88%?). Which of course would not provide peak performance and I’m ok with that. But to studder and actually perform worse was puzzling. Have you experienced that issue at all or just simply the discharge continuing to be an issue? I’m thinking I may just have to run in balanced mode still with it which of course depreciates the performance slightly, but is still tolerable. As long as I am not getting the discharge and performance drop that’s all I am looking for. Also, I agree with @jared_kidd they should hire you and get this fixed :rofl:
