ThinkPad lenovo not charging
Hi I need help the lenovo ThinkPad is not charging ,not sure there's a problem with the port .
12.1" business laptop released in June 2012 by Lenovo. This laptop uses multiple product numbers, which vary based on configuration.
Remove the battery and the AC adapter (charger). Press and hold the power button for 3 - 4 seconds with these removed. Pop your battery back in, along with the AC adapter. If it still refuses to charge, you could be looking at a bad battery or possibly a bad charging circuit on the motherboard.
Usually this is due to bad charging circuit in Thinkpad.
If you have a meter, remove the battery and you will see a set of connector from Thinkpad to battery.
The first 2 slightly longer connector pins is Negative. The next 3, you should get 3.3v when power adapter is plugged. If one of them is missing, your battery would not charge.
