Battery crash when turining off Swift 5 SF514-54T

Hey!
Since some days my swift5 has a problem. When I turn off the computer (shutdown, not power-safe) and turn the computer on again the battery crashes down in some seconds. Windows starts (for example at45% battery capacity) and then turns down in some seconds to zero.
If I use the battery until it's end (more than 5 hours runtime!) nothing special is happening. The error is just occuring, when I turn of the computer.
What can I do?
Does anyone else have the same error?

    (1) Search 'cmd' in Windows start menu.
    (2) Right click command prompt near top of menu.
    (3) Click run as administrator.
    (4) Enter 'powercfg  /hibernate off'

    Thanks fot the hint. But hibernate is not the problem. Because when the battery has more then 90% this issue is not happening. Only when the battery has already lost around 50% of it's energy or more.

    Did you try it anyway? This Windows function is buggy.

    I will try it :-)

    I believe you have a battery reset button under a pinhole on the bottom of your laptop. Try doing a battery reset by shutting down and removing all connection, including the charger. Use something like a bent paperclip to press and hold the reset button for 15-30 seconds, then release and wait 15-30 minutes. Reconnect only the charger and wait for a full battery indication, the turn it back on. That should get the battery reporting the correct information...

    I will try it :-). I saw somewhere that I have to recharge using the original power supply, not USB-C - is that correct?

    Shouldn't create the issue you're having.

    I made the battery reset and reloaded after waiting with the original power supply... but no result.
    I investiagated the problem deeper and found out, that the problem does not appear, when battery is over 60% loaded. Only a low battery-loading of 30/40% and then turning off the computer (completly) is heading to the result, that after turing the computer on again (after about one hour standing) the battery is crashing down during the startup-sequence quickly and the computer turns off after windows has started. Does anyone have the same problem?

    (1) Search 'cmd' in Windows start menu.
    (2) Right click command prompt near top of menu.
    (3) Click run as administrator.
    (4) Enter 'powercfg /batteryreport' at command prompt.
    (5) Then return to the desktop. Open file explorer.
    (6) Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser.
    (7) Post screenshot of the first part of the report if possible that compares design full charge capacity with its remaining full charge capacity.

    Hey JackE!
    Thanks for your answer. Here are the reports:
    This spreadsheet is interesting. Because it shows one of this energy-dropdows. You can see it 2022-03-19 at 20:40:22, when I turned on the computer again at 28% battery. Then it fell down to 2% in only 40 seconds (during startup)...

    What was the original full charge design capacity near the beginning of the report?

    The battery has lost about a third of its factory design capacity. This is in the normal range for a 3-4 year old battery. However, as you noted the battery has dropped below its critical charge level of about 5% at least once. This can permanently damage a lithium ion battery. This is why the Windows low battery alarm comes on at about 10%. It should then be plugged in so it doesn't drop any further to 5% or less.

    Battery monitors aren't very accurate, so it's possible it's gone below 5% multiple times especially on unplugged startups with a rather low 10-20% charge battery to start with. Startup consumes a lot of power so it's not a good idea to startup unplugged with a low battery.

    So I suggest that you keep the laptop plugged in as much as possible to see if the battery can recover enough to act more normally after a few weeks. I also suggest that you open Device Manager, click on the batteries folder, then right click and uninstall all the drivers you find in the batteries folder. Then shut down Windows normally. Then re-start Windows and let it automatically re-install fresh copies of the battery drivers. That may help increase the accuracy of the battery monitor.
