You need to send the computer to Lenovo depot repair center for repair.You may try to use other lenovo adapters just to check if the adapter is the problem.
You may first try performing the steps mentioned below:
1) Connect the AC adapter into a known working AC outlet and to the DC jack on the notebook. 2) Verify the correct AC adapter is being used, and not a third-party replacement AC adapter. 3) Do not connect the AC adapter to a surge protector or extension cord. 4) If the DC jack on the computer is loose or damaged, the computer may require service. 5) Some AC adapters have a POWER LED indicator and can be confirmed as receiving power by ensuring the LED is lit. If the AC adapter is damaged, or the LED is not lit or continuously flickers when plugged into a working AC outlet, the adapter must be replaced. 6) Attempt to turn on the computer normally. 7) Press and hold the Power Switch for 5 seconds. 8) Remove the battery. 9) Disconnect the AC power adapter. 10) Press and hold the Power Switch for 5 seconds. 11) Connect the AC power adapter. 12) Attempt to turn on the computer. NOTE: If the computer turns on without the battery, connect and charge the battery for 24 hours. 13) Disconnect all external devices that are connected to the computer. 14) Attempt to turn on the computer. 15) Remove any additional Random Access Memory (RAM) that was installed in the computer. 16) Attempt to turn on the computer. 17) The troubleshooting steps listed above should resolve your issue. If you have completed all of the steps and the issue is not resolved, service may be required.
Sounds like a build up of static electricity. Try doing a power discharge.
1: Take out the battery. 2: From the adapter box (not the wall) unplug the power cord. 3: Press the power button 10 times. On the eleventh time hold it down between 25-35 seconds. 4: Plug in batter and power cord.
The computer should turn on. If not, the most likely cause is the system board or the AC adapter. You might want to try another AC adapter to ensure that the adapter is not the issue. If it's not the AC adapter then the system board is most likely dead and you need to call Lenovo (800-426-7378) to see if you're under warranty and can get the computer fixed.
I believe the power system there is different and unstable at best. Get yourself a computer travel kit that has all the different charger adapters for what country and power grid you are going to be in. I know I was in Macy's the other day and they had a decent one that had a multitude of adapter tips and voltage settings for under 30 bucks.
When you plug in the adapter into the laptop a LED lights up to indicate that it is connected to the mains supply and is charging. The adapter is faulty or the connector is not making proper electrical contact. Wriggle the connector plug to see if the charge light comes on, if it does then the loose connector needs repairing.
Check the adapter with a multi-meter, the voltage reading should be a slightly higher than the voltage that is printed on the label on the adapter. If the voltage is more than 10% below the nominated voltage then replace the adapter it is faulty.
If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.
If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.
