Sudden drop of battery level (v1jp)

I have read about many of the wear issues affecting the V1JP (and some other ASUS models). Today I experienced something really strange - I do not know if it is directly related to this battery wear issue.

Vista was reporting that I have about 50% battery left, 1 hour 20 minutes. A minute or two passed, and suddenly came an alert that the battery is nearly empty (at 7%) and I should charge right away. I think it is highly improbable that the battery really lost that much charge in so little time.

Did anyone else experience such a thing? Is this an indication of a possibly faulty battery?

(I plugged it in and now it is charging up from 7% ... )

 

I haven't seen this behavior with this model yet but this happens all the time with various cell phones. The measurement/prediction algorithm is making mistakes, it looses track of how much capacity is left and then suddenly corrects itself. The wear problem people have been talking about is separate and easily shown in terms of total possible capacity with one of the free software packages out there.

 

Not necessarily... I suspect that this wear problem is related to deeper and more insidious faults in the battery firmware and/or hardware, and in advanced stages more radical faulty behavior can happen... like the one described by the first poster.

 

After recharge completed wear level increased from 5% to 10%. Great So I guess this is somehow related to wear.

 

I'm sure you have read this.

I do suggest you read through the entire thread or continue where you left off.

There are a few experiencing what you just experienced.

Here's what I suggest, remove the battery, then place it back in, and see if NHC reports different numbers, you may want to do this a couple of time, and once with the AC on. As possibly restart notebook while doing this. This will allow NHC to read the values properly.

 

This story is rapidly turning into one of these wear issue ones. I ran on battery again, when reaching about 48% it dropped to 8% suddenly, after rechargig (which jumped from 58% to 94%) I now ended up with 15% wear. 10% more in just a few days. Yeee

I haven't recently used the notebook on batteries, only in the last couple of days. And its almost as if it is trying to rapidly catch up to the "wear level schedule" (The notebook is four months old)

Restart/remove/reinsert etc. does not change the wear level value.

 

hi, i recently had this annoying issue with my asus s6f. anyway, i was rather upset as i had just purchased this notebook in dec of last year. if you call them on their notebook support line they will give you a new battery if you push for one. Since i am in North America i recieved free overnight shipping to and from them. My s6f normally gets 4 hours on its defualt 6 cell battery. after a few months i was only getting, and hour and a half so i filed for and RMA with them. hope this helps, best of luck to you.

Another go on battery another 5% wear (now 20%). I wonder how long I can keep this up?
