ok at least u start to explain.
lithium batt has a self discharge rate of about 3% p/month n if u attached the batt to your device it has a higer discharge rate.
full charge your batt n remove from device for say 24hours n install back to check the pecentage. then see what u left. u should not see much changes . if not your batt self discharge is too high
Here are average self discharge rates for the following chemistries:
|
NiCd |
NiMH |
Lead Acid |
Li-ion |
Li-ion polymer |
Reusable Alkaline |
|
|
Self-discharge / Month (room temperature) |
20% |
30% |
5% |
10% |
~10% |
0.3% |
Its not the battery problem because Lenovo send the engineer to my home and replaced with another new battery, problem still same.
its not so easy to remove the battery as normal laptop.
just imaging u want to take out the battery from a ipad...

most product r designed with power cap. for up to 8 -10 hours usage. n there is nothing much u can do except external source
