When I connect charger with my laptop 30 sec show battery is charging after 30 sec one message show:- QuickSet The Ac power adapter type cannot be determined. your system will operate slower and battery will not charge. This problem might be solved by: -Ensure the plug is inserted completely for best system operation. -Connect a Dell 65W AC adapter or higher. laptop is new so what is problem. but from another charger laptop is charging after 10 - 15 times charger connecting dis connecting.

check power cord is fully inserted into laptop
if no joy
try also forcing a power down by holding in the power button for 30 seconds and then try power button again to power it up .

might be in hibernate mode !

del recognition circuit may have failed in charger , or could be fine central pin on charger plug or laptop plug has broken connection,it is used to tell laptop that this is genuine dell charger.If you remove battery will laptop work off charger.if does then definitely one of the three problem possible . for first only soln try another dell charger first,often has to be one to suit your model ,common dell problem ,if then work and charge battery ,you will need to replace charger as recognition circuit failed. If either of last 2 can repair but need to pull apart repair broken connection ,or open up laptop and check power connection and repair connection . If you remove battery will laptop work off charger.if does the definately one of the three problem possible . for first only soln try another dell charger first,often has to be one to suit your model ,common dell problem ,if then work and charge battery ,you will need to replace charger as recognition circuit failed.

Sounds like the ID chip in the battery pack has gone bad. This is a common issue with dells.. Otherwise your looking at the sensing circuit of the motherboard. If you know someone else with the same power supply as you try there power supply and see if it works.. If you continue with the same issue then contact the reseller and look into warranty repairs.

It seems that the your power adapter does not have correct amount of power.

Perhaps remove the multi-bay battery, and let main battery charge all the way. Then reattach multi-bay battery, and see if it's recognized.
(Will charge)

That is AC adapter (Charger) removed, then remove multi-bay battery.
Plug AC adapter back into laptop, THEN plug AC adapter into power.

[You do Not want to unplug an AC adapter from a laptop, with the AC adapter plugged into power. Could be a power surge/voltage spike. Unplug AC adapter from power, when plugging into laptop, or unplugging from laptop ]

Main battery charged, unplug power to AC adapter, unplug AC adapter from laptop. Plug multi-bay battery in, then AC adapter.
(Then plug AC adapter into power)

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,

Hi swd6,

Just to isolate the issue, could you kindly remove the battery from your laptop and using the AC adapter alone charge the machine. Please let me know if it's charging.

Thank you for using FixYa.

Hi smialkovskyi,

With this specific concern that you do have, unable to turn on your Lenovo Z560, there 3 components that need to be checked. Your battery, the AC adapter (charger) and as well as the DC In port.

1.Based on what you have said, with the battery alone you have noticed that it's led indicator will show however still can't turn on system. Battery seems to be in good condition however no enough charge to turn on the system.

2. For your AC adapter, when you're using it without the battery nothing happens. To check if this is defective try using another AC adapter that is compatible to your unit. If your computer turned on using another AC adapter then your charger needs replacement. (You may also try using your charger to other unit where it is compatible, just to test).

3. However, if after doing the previous instruction and still system won't turn on then it could be the DC In port which is defective. This port is built in to *********** board.

After doing all these you need to contact Lenovo. They might be replacing your charger or *********** board if system is under warranty.

Hope this helps.

Thank you for using Fixya.

With my laptop, I held the power button (still with everything removed) for 30 sec to decharge the capacitors. Finally, put the battery back in and plugged in the adaptor and everything worked

Hi, Sounds like the charging circuilty is starting to fail,

Check the connection from the power lead to the DC input , is it tight ?or is there a lot of play ? if so bad connection ?

if it still under warranty, get it looked at before it stops charging completey.

Lastly , is it possible to try another charger ? make sure it the correct voltage and amps. The charger could be going down.
