smbusb VS HeadsetControl

On any BMS there will be a chip, sometimes 2, which are the brains of the operation. The TI bq-series are pretty common. Some of these have public documentation, some are private. A lot of them are password-protected if you want to overwrite the original programming. There are various tools for interacting with them, from free open source to paid You don't always need to reset it, sometimes just replacing the cells then shorting across the switching side of the output is enough. But without knowing what you're getting into it's a gamble.

Sorry, Vantage is Lenovo software, but it has a function to improve battery gauge accuracy. It made more sense when mentioned in the Thinkpad forum, but I figured I'd crosspost my request here too. That being said they of course did the major dick move of only ever adjusting measured capacity down, even if the cells were literally at 4.1V when the battery said it had run out. Therefore, I first used the smbusb utility to edit the dynamic battery data and blank out the battery full charge capacity (which actually sets it to the absolutely ridiculous 65535Wh). After that when running the gauge reset in Vantage the battery was more than happy to report a more realistic 102.78Wh of actual capacity, despite still reporting a design capacity of only 93.6Wh which thankfully didn't raise any issue. Unfortunately while trying to experiment with the BMS firmware further to try and adjust the voltage thresholds to better fit the new cells, I corrupted something. The BMS still reports and sort of works but whenever I try to make further edits to the firmware I am greeted with errors.

I've been playing around with my failing LGC 70++ 9-cell battery after re-celling it with SANYO 3500mAh cells. Had some great success with a tool called smbusb (got the battery to report as 105WH after a gauge reset in Vantage) but I think I killed the BMS eventually by flashing some wrong values and corrupting the firmware and can't seem to get it back. I've looked around eBay but most of the batteries on there are either for T410/T420 (yes I know you can make them work in T430, but they might use a different BMS chip) or ridiculously expensive for 10-year old batteries. So here I am hoping that someone here has an old, damaged, dead or unloved battery that I can take off their hands.

You can use SMBusb and something like an FX2LP. Then to connect it, I would just use some normal Dupont 0.1 connectors (make sure they have female -> male), or of course any piece of wire if you don't mind spending more time trying fiddling about.

See HERE for a device that lets you connect to the data pins on laptop packs and read info from them. Some packs you can find pinouts online, others you have to figure out yourself.

I guessing it needs to be put into a state todo this? The program https://github.com/Sapd/HeadsetControl can query the state of the Game/Chat mix dial. I pretty much just use this dial for Discord, so at minimum I want to have it so using the Game/Chat mix dial changes the volume of the Discord application. Ideal would be having a virtual sound that gets mixed back into the sound output.

For the arctis, you can likely use https://github.com/Sapd/HeadsetControl I'm using it with the nova 7 and it has 4 built in equalizers which do the job for me. You miss out on built in chatmix like sonar has but you can implement it pretty easily using pulseaudio virtual audio devices and interfacing with headset control to get the chat mix level from the headset. If you want to send me a dm once you get your system set up I can send you over a private repo I have for it!

Same here. My Logitech gaming headset works great in Linux. I do have to use some third party thing to adjust the goofy LED colors and side channel volume, though.

For the headset, this is a bit more difficult, if and only if, you are looking for a full compatibility, meaning all the functionality you would have in Windows. I would recommend looking at HeadSetControl repository if you need a full control of your headset under Linux, else all basic functionality should be available on most of the Headset market (please verify using google).

I also used it in Ubuntu with this little cli-tool headsetcontrol from here https://github.com/Sapd/HeadsetControl which works great with the G533. It also supports some other headsets, so it might be worth checking out.

Everything using Bluetooth should work, sometimes with a tiny bit of tweaking. If you want a bit more of functionality, look at https://github.com/Sapd/HeadsetControl you will find a list of supported devices.

This is probably what you want https://github.com/Sapd/HeadsetControl

I switched to linux a few weeks ago and talking with friends in discord is really annoying because of the sidetone. I've tried disabling it from alsamixer(there was no sidetone option) and HeadsetControl.

With my current headset, the problems I've had on Linux were the following: - Lack of battery notifications (mitigated with HeadsetControl) - Lack of surround settings - Can't use the programmable button
