Lenovo B40 battery not charging

One day while using my laptop, the battery of my laptop was about to drain completely so I plugged it in. But the battery was not charging. I changed the plug point thinking there was some problem with the socket but still it did not worked. I removed the battery, reinserted it and tried to charge again but the problem still presisted.

 

Then I removed my battery and plugged in the laptop. The laptop was working fine.

 

Keeping the laptop plugged in (laptop shut down) and reinserted the battery. The battery charged for a while then the power button and power light (in the front on the edge of the body) started blinking. Therefore, I removed my battery.

 

So now I charge my battery by first plugging in the laptop (battery removed) and then reinserting the battery. The blinking poblem also occurs very often. 

 

Also when the battery is attached to the laptop and I try to charge it the laptop does not powers up.

 

Model: Lenovo B40

  1. Unplug AC adapter (remove from notebook).
  2. Remove main battery
  3. Press and hold the power button for 30 seconds (power drain)
  4. Replace main battery
  5. Replace AC adapter

Tried battery gauge?

If doesn’t work, you can try by un-installing LENOVO UTILITY 

 

Update us how it goes.
