Re: L380 Yoga - "slow USB charger connected"

My suspicion is on the Power Manager driver update version 10.0.88.0 (I received the update on the 25th of March). The weird thing is that rolling back to the previous version doesn't solve the issue, so I'm a bit lost. Also in my case the problem started after some time, more or less after two weeks of normal use (normal charging cicles, I got my laptop on the 11th of March). The even weirder thing is that I have the impression that despite this issues when I plug in the charger, I have normal charging times, as fast as I was used to have before the problem appeared. Do you also have the same impression?


Yes, that's exactly my suspicion. The Power Manager driver update may have caused this problem. And even for me it didn't start immediately but after a couple of weeks. Really weird.

I have not yet figured out if the charging speed is normal.

Re: L380 Yoga - "slow USB charger connected"

If I recall correctly the issue started on the 25th of March for me, but I'm not 100% sure (let's say 90% sure Smiley Wink), after two weeks of normal use. 

 

Answering your other questions, I have no idea what it takes to have some support from Lenovo here. 

 

I'm based in Switzerland and I got my L380 Yoga directly from Lenovo.ch. The unit was shipped from China. Ordered on the 26th of February, got it on the 11th of March.

I contacted technical assistance, they told me that they are aware of this issue and are working on a new update that will be released in the coming weeks and should fix the problem.

Re: L380 Yoga - "slow USB charger connected"

thank you for taking the time to contact them and sharing it with us.

 

just grab your fire extinguishers and hold fast until the update! Smiley Wink

 

Jokes aside, good to know that at least they are paying attention, and let's hope they launch the update fast enough and that they improve Q&A for the software release process.

 

Cheers everyone.

Have a nice week

Re: L380 Yoga - "slow USB charger connected"

Hello,

 

Could I ask you all receiving the message to post your BIOS version please. If you type System Information into search and then select it the BIOS version should be about the 11th row.

 

Thanks

 

Andy

Re: L380 Yoga - "slow USB charger connected"

Thanks All for bringing this to our attention.

 

Engineers have been able to reproduce the described symptoms and a case has been opened to request a fix from the BIOS teams. Actual functionality of the system should not be affected. If people wish to avoid receiving the message a roll back to BIOS version 1.18 R0RET35W will remove the message until a further update is provided for which I currently have no estimated date; it's too early to say.

 

The immediately previous version 1.18, and others, can be downloaded from the following linked to site, please scroll to the bottom, and please also don't forget to disable the BIOS Secure RollBack Prevention setting in the BIOS Security menu.

Re: L380 Yoga - "slow USB charger connected"

I had the same issue. I was actually about to return the machine to the store because I thought it was faulty - until I found this thread.

 

After rolling back to the previous BIOS version, the issue is resolved for now. I'm glad it's a fixable software bug instead of a hardware defect.
