just bought new E430 3254- A11 ,here's the spec:
Intel CoreIntel i7-3612QM (2.10GHz, 6MB L3 Cache, 1333MHz FSB), 14.0" 1366x768 LCD, NVidia GT630M-2GB, 4GB 1333MHz DDR3, 750GB HDD (5400rpm), etc
the problem is, I've been using thinkpad for about 2 years, so I knew few things about thinkpad and it's speciality in battery,
I set battery threshold between 50% and 70%, so if the battery capacity right now is 69% and in state of AC (charged), the status should've "No Activity" but the actual status is "Charging"
it's always charged to 99%, it doesn't stop at 70%
and this is the settings for the threshold
I've done battery gauge reset, but it didn't works
Thinkpad Power Management Driver : 1.65
Power Manager Version : 6.32
any help would be greatly appreciated, thanks

It does appear that you have a good working knowledge of the Battery Reset Function. But if all the steps are followed it should have resolved your issue. I am listing the steps for resetting the Battery Gauge and I would like for you walk through the steps one more time. If this does not work then we can look a little deeper to find the issue.
After the battery firmware is updated, the full charge capacity will be reset to the battery's design capacity. Because of this, it is recommended that a battery fuel gauge reset be performed after the update is complete. This will update the full charge capacity to an accurate value. If this is not done, the battery may report a sudden drop in the estimates of remaining percentage and remaining time once the battery is nearly empty even after updating the firmware. To perform the fuel gauge reset:
After the reset is complete, the battery gauge will be calibrated.
If Power Manager is not installed or no Battery Maintenance button is available in Power Manager, the battery gauge can be reset by the following instructions.

Here's one thing you can try:
The Battery threshold is active only while the system is "online" and not when in hibernation or sleep.
The simple test how you can test it is to let the system started <no Hybernation, no StandBy> and check if now the threshold will work.
This is per Henrik at Lenovo in this thread:

a new bios was released last week fixing an issue that Battery Charge Thresholds is not working.
