Y700 Battery Full Charge capacity reduced suddenly

2016-12-15, 19:22 PM

My laptop battery's full charge capacity has fallen from 60Wh to 35Wh all of a sudden. It used to be around 58-59Wh couple of months back, then I began using conservation mode for a few weeks. Later when I went back to normal mode, my laptop's backup was totally deterioted. It began lasting under 3hrs as opposed to 5hrs+ earlier under light load. Then I discovered the reduced full charge capacity issue. It's quite weird to see such a massive loss in capacity considering that I have under 70 cycles on the battery and the laptop is barely 10 months old and used quite sparingly.

Things I have tried but to no avail:

1. Calibration using one key recovery(The laptop kept working for over 2hrs under 2% battery while I did this!)

2. Calibration using energy management

3. Reset windows.

4. Fresh install windows.

Service center and lenovo india are highly ignorant towards the issue, calling this as an imported laptop(I got my laptop as a gift from my uncle in US, non 4k y700 is sold in India as well). The international warranty s**ks big time.

Any help will be greatly appreciated, more so if you don't ask me to disassemble my laptop!

Thanks :)

Hi amitoj , 




As you have done fairly enough steps to describe the battery issue , you may need to have your machine called in by your uncle for inwarranty support specially if international warranty in India would not be available for this specific model. 


You can have him consult with the US tech team for best option regarding this scenario.
