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.
Hi, Since you have already replaced the ac adapter. The problem is still there. the most likely cause of the failure is bad motherboard. Remove the battery from the laptop and disconnect the ac adapter . Press the power button for 10 seconds. Reconnect the ac adapter and try powering on the system. If the same doesnot work

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.
Generally, it is an indication that the system is not receiving power. Here are some possibilities:
Bad AC adapter, not providing any/enough power to start system/charge battery. Try a different AC adapter, see if anything changes.
Bad damaged AC connector on motherboard. If the power connection to system is wobbley and not firm, then the adapter plug may be broken. It is possible to got the plug repaired/replaced but generally this is a motherboard replacement.
A component is preventing system from starting. Remove all customer removable items (HDD, CD Drive, RAM, Modem, Wireless Card & battery) see if system will power on and give any error codes (The lock lights on/flashing) If the symptoms change with the removable parts out, then add them back one at a time and see if the system will turn on. If no change, again, replace the motherboard.
Just to humor me, are you using any peripherals with your laptop when this happens, such as a wireless mouse, USB connections such as digital cameras? Try to take these away when recharging.
There seems to be 2 issues here. 1) Recharing batteries: To prepare the batteries for long-term use (I do not know how long you've had the batteries...try draining the batteries (both of them), and then recharging it to full 2x before using them without the AC Adapter. This should clear the problem.
2) AC Adapter only works every other day: When you swapped the power pack, was it with a new AC adapter, or another used one? Also, have you tried using a different outlet than the one you normally use? Let me know how this turns out.
