The AC adapter white power light is not coming on when I plug the power adapter into the laptop. I am relying on the battery which is running down and I am unable to charge it up. Do you think I need to replace the AC adapter. I thought it might be because I wind the cable up when I put the laptop away and the cable and power pack has been damaged in some way. The model is a CQ60 notebook

Try another cord/charger with the EXACT same power specs as the original. Has the AC jack in the laptop been damaged, loose connection, due to pulling on the cord while plugged in? Try to wiggle it when plugged in to see if there is any connection. The AC jack may need replacing, if your lucky.

In order for the AC adapter to work the battery must be in good condition, why? Because the system runs of battery the AC adapter just keeps the battery charged up while in use, if the battery is open or defective the computer will not run on just the AC adapter.

Hi m529,

I see you are having issues with you G550 charging.

You mentioned that the light on the charger is lit up but then it suddenly switches Off, and you also mentioned that the charge still has a light but the power is somewhat low despite of a fully lit up charger Light.

Have you tried draining the power from the system?

• Remove the battery and the Charger or AC Adapter as well call it from the G550 then press and hold down the power button for 10-15 seconds to drain power from the system motherboard.
• Once drained connect the AC adapter but do not connect the battery yet, then turn the Laptop ON to see if the system will power ON using the AC adapter/Charger if it powers up then there is no problem with the AC adapter/charger.
• After testing the AC adapter if it is working power down the Laptop doing a normal shut down.
• Once shut down or turned Off insert the Battery back in the Laptop then turn the Laptop ON using the battery only without the AC adapter/charger see if the system will turn ON using the Battery only.
• If the Laptop powers On using the battery alone with out the AC adapter then the battery is most likely working as well on the issue.
• Now power down the Laptop then connect the AC adapter to the Laptop with the Battery in the Laptop as well then turn the system ON again see if the problem will Occur again having the battery and the AC adapter/charger if the Problem happens with both Battery and AC adapter on the Laptop then the problem is the Motherboard, most probably the motherboard is having issues relaying power from the AC adapter to the battery and may be sent to the Depot for repairs.
  

I suggest that you call Lenovo for further information about your system, if you still have warranty and is still in the one year period then your system will be covered for any repairs needed - you can call @ 1 877 453 6686 for troubleshooting, you will be asked for a serial number Located underneath the Laptop on a small white sticker that states s/n meaning serial number.

I hope that this Helps.

Have a nice day,

This is only the first of many things you may need to do to determine the fault. But it is a process for determining the exact cause.

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a 'power reset' of the notebook.

1. Unplug the ac adapter. Keep ac adapter unplugged.
2. Remove the battery and keep the battery unplugged.
3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
5. Normally power on the notebook.
6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
   If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

Try using a different adapter and see if the problem persists. If so, then change the power supply and try using a new adapter again.
