  • It is the TMP614-51-50FJ Thanks -Matt
  • Thats a shame, its about 3 weeks past the 30 day return period. Thank you, ill wait for an update (if there is ever one). Ive been watching for a bios update on the product page for about two months now, but nothing yet. If there is no update by the time the warranty expires (in a year or two), ill manually desolder the…
  • Sorry for the delay- Viewing it on an oscilloscope shows most of the energy near 1.2 MHz, nothing seems to be audible, most of the audible noise is from the processor / processor power circuitry area. Plugging in some headphones/headset does not make a difference unfortunately. If you have any other suggestions, I would be…
  • Indeed. I plotted the speaker output on an oscilloscope, and it was pulse amplitude modulation with a max amplitude peaking near 13v. The temp rises up to 30c above ambient when the laptop is suspended (In sleep where the fan wont run) and less than that with the fan running. The temps were checked using a thermal camera.…
  • Even with this speaker power management issue, my battery life is still about 2 hours longer on linux than on windows. (My old Acer laptop experienced >6 hours longer) linux is required for development on this laptop. The issue wouldn't be so bad if the speakers didnt reach ~60c (!) and the battery didnt last less than 20…
  • Thanks for the comment, but this did not make a difference. I have the battery power consumption tied down pretty tight, except for this issue. I tried a few more potential solutions and the issue still stands. Strangely, running this seems to help the solution until the next time it goes to sleep. This disables power…
  • Thank you for commenting, I would be leaning toward that, but USB-C is still fully functional, and the issue can reappear when booting without moving the laptop. Though it could be a bad bga ball on the thunderbolt controller since some of the time it gets initialized, and some of the time it doesn't. Best regards, Matt
  • Hello, Has there been any update on this? I've tried four different operating systems with kernel versions ranging from 4.19 to the brand new 5.3.2, but the issue still stands. It appears to be a bios issue, but I cannot prove that. 16 hour max battery life is hard to work with since it is 16 hours sleeping, and far less…
  • Thank you for your comment, I updated to 1.03 (It was 1.01). The fan seems to run significantly less, but the issue persists. That will help power-wise in the long run, thank you for that. Do you have any other potential solutions you can think of? Best regards
