Hi,

I have the same issue as above. The battery drains dramatically overtime whilst the laptop is off and it is a new a laptop. It is a Acer Swift SF314-54. I have unticked the turn on fast startup icon as suggested but how do I find the Acer Quick Access dashboard so that I can untick the Power off USB Charging option?

Thank you

Install from Acer site for your model, that's the only genuine source.

Hi @Simon20192018,

# Try to update the battery driver

1. Hold windows key and hit letter X.
2. Choose the device manager option.
3. Go with the option battery.
4. Under the title battery.

5. Right click on that option ----> Update all driver under the title battery.
6. Choose "search automatically". 

Check this T/S and post the result. ​

Realize also that some of your USB ports support power-off charging, so you can charge your phone even with the laptop turned off. If you have anything plugged in there it will drain the battery at whatever rate the device uses, even if it's not being used while the machine is off (as would be the case if you had a flash drive plugged in there).

Hello everyone,

I'm using a brand new ACER swift 5 i5 laptop for about 5 months. but the battery drains so fast. I can only use it for about 4hrs(100% - 0%). Can anyone help me to fix this issue. And i want to know do windows 11 drains the battery soon?

Install Acer Quick Access, if not already installed. Open the app/program and uncheck Power of USB charging - this will help battery last longer when off.

I seem to be facing the same issue. When the laptop (Acer Swift 3 SF314-43-R2LX) is completely shut down the battery drains (like 10% to 20% over night, I need to investigate further to pinpoint precise figures, but I'm seeing a consistent pattern).

I'm running Linux. Is there a way to make the charging port setting from Linux? Sounds like it should be a BIOS / UEFI configurable option.

There are other sticky changes, that can't seem to be set from Linux, but survive reboots and carry over OS boundaries.

For instance: stop charging the battery at 80% (to save battery wear). I set it from Windows (in Acer Care center), but it seems to stick. Even under Linux charging stops at 80%.

Where are these settings stored and how can they survive a complete shutdown?

Are there any other settings like it?

How can one change them from Linux?

There's also a microphone array in the laptop, that seems to be able to wake it up with your voice (read it somewhere in an advertisement). How could one disable that?

billsey

If you have anything like Wake on LAN enabled then a "complete shutdown" doesn't actually turn everything off. In that case the WiFi is still enabled, allowing the system to see a wake packet and wake up.

@billsey Thanks for your reply. Good idea, but I couldn't find a "wake up on lan" setting in the UEFI / BIOS.

Are persistent settings maintained elsewhere nowadays?

(Hybrid Mode is disabled in Windows 10)

Something seems to be leaching power when the laptop is shut down (also shutdown from Linux that is).

billsey

Wake on LAN is usually configured at the driver level, so in the OS.

@billsey

I can't find Wake on LAN in the BIOS. Is it a persistent setting that survives reboots and even cross OS'es?

I'm sure now that the battery charge limit persists from Windows over to Linux. In Linux charging stops at 80% also, whilst is was set in Acer Care center under Windows. I can't find a way to change the setting from within Linux.

Where are these settings persisted? I can't find them in BIOS. Does Acer have Linux drivers for them??

billsey

Yes, once the driver has WoL enabled the hardware monitors the network even when shut down.

I don't know if Linux has those settings enable in the drivers, I would expect so with the WoL and likely not with the battery percentage.
