The laptop works completely fine while connected to DC directly, with or without battery in it. The problems are as follows:
- as soon as I unplug DC the laptop stops immediately. (while charged, charging or not, but recognized battery is in it.
- I can't start laptop only on battery with the power on button. If I press an release it several times it may start for a while( 5-8secondes if I keep power on pressed but shuts down afterwards)
- If I keep pressed the lenovo care button(the red tool case button) the laptop starts and I'm able to operate it until battery drains out, while is kept pressed.
I've reset bios also from CLRP1 but doesn't resolve the problem.
Please let me know how should I fix this problem, while the battery works in other laptops also.

I suggest you to update the Power Management driver and BIOS also from the below mentioned web link a per your Operating System. Kindly fill your 7 digit MT-M number(0769EAG) and then click on submit.
After updating the Power Management driver and BIOS, please check the issue, if the issue remain same then please shutdown your system and then refix the battery in your system and then check the issue. It may resolve your issue with battery.
