IdeaPad Duet 3i - Battery Drain After Shutdown

2021-05-18, 14:34 PM

Hello Everyone! First of all, happy Eid Mubarak for those who celebrate it!

 

It's been almost 3 weeks after purchasing my IdeaPad Duet 3 10IGL5, and I'm having a really serious problem with this tablet.

 

My tablet's battery keeps discharging even after it already powered off. I really remembered my battery was around 30% before shutdown on last Sunday night. And before I write this topic, my battery was already 0%! It's really bad I even need to recharge my tablet after few hours of being turned off, not to mention it will affect to battery lifespan (fully discharge to 0%).

 

I've been experiencing this problem since day 1, I updated my Windows and drivers especially BIOS to latest version EQCN24WW. I even turned off fast startup and disable Always on USB on Lenovo Vantage. For additional, I always use battery in Conservation Mode.

 

Any thoughts, suggestions or workaround for this problem?

I also found someone with similar experience months ago but no replies:

Ideapad Duet 3i - Battery draining after shutdown - BIOS problem?-English Community (lenovo.com)

 

That is all from me, really sorry for bad English. Thank you very much!

Hello ikikinoko,

 


Welcome to Lenovo Community

 

 

Kindly go to BIOS and load the default settings, be sure to save before exiting.
You may also check for updates, thru the support site (instead of Vantage)
Update us how it goes

Hello Lorenzo_Lenovo, thank you and sorry for the late reply!

 

I read your reply last night, and followed as you asked. I set my BIOS back to default and saved it, also preformed update on support site (all my drivers were already latest).

 

I recharged my tablet to 60% before going to bed so I could check it back how much it discharged. As I generated battery report via powercfg.exe (picture above), really shocking that battery was still 60%.

 

So far your suggestion works like a charm but can I keep checking it just for a week? I'm not kinda sure so that I want to make sure that problem is really solved, I will collect more battery reports per day and update it here.

 

Regards,

ikikinoko

Hello Lorenzo_Lenovo, thank you for waiting my progress!

 

I observed my tablet for a week, and concluded that Always On USB (BIOS or Vantage option) is the root cause of battery discharging.

 

My workarounds were:

Day1 - 4: I left BIOS on default as you suggested, no discharging occurred.

Day 5: I modified some BIOS settings (disabled PXE Boot to LAN, Intel VT, Always On USB), discharging occurred.

Day 6: I have suspected Always On USB to be honest, so I enabled it back (it also shown Charge in Battery Mode sub option but I kept it disabled). Discharging was still occurred.

Day 7: I enabled both Always On USB and Charge in Battery Mode, no discharging occurred.

 

That is all! Enable Always On USB (include its sub option) solves battery drain for time being, but I hope the next BIOS update can address this problem. Once more, I really thank you for your solution.

 

Regards,

ikikinoko
