baterija je stara nekih 2.5 godina... naletio sam na jedan zanimljiv post o ovom laptopu i ovoj bateriji, nasao sam ga na ovom forumu:

"i found the solution to this problem. my laptop's about 3 years old and at some point i got the orange flashing light all the time, the computer only worked when plugged in using the ac adapter, and would shut off if not plugged in. i got a new laptop battery, the orange light was still blinking after plugging it in, i checked under the program, Lenovo care -> Device Configuration -> battery management ->power tab, and it showed a battery icon with "Unknown" and didn't display the amount of charge in it. It showed only ac adapter as the power source. i turned off the computer, removed the battery, turned it on with only the ac adapter. After Windows started up, shut it off again, plugged in the battery, ac adapter, and turn on. After Windows loads, i removed the adapter plug, the computer stays on but with a message 'battery critically low', i went to the lenovo care menu again, checked under the power source, and the computer has recognized the battery, it says "0%". I plugged in the ac adapter and it started charging going steadily up. The blinking orange light stopped blinking while being charged, and after about an hour or so it turned green at about 95%. I'm now able to use the laptop normally without plugging in the power adapter with only the charged battery."
