Issue with charging battery
I own a Dell Inspiron N411Z laptop. Last week I purchased a new battery because my old one would not charge beyond 35% (the maximum charge decreased everyday over a period of two months). The new battery worked fine for a day or two before it stopped getting charged above 50%. I followed the advice in another discussion on this forum on a related issue. I drained my battery to zero (until the laptop shut down, disabling any form of automatic sleep/shutdown/hibernation on account of low battery) and removed it from the laptop for ~3 hours. Then I charged the battery with the laptop turned off for 4-5 hours. Now, although I can charge the battery to 100%, my laptop suddenly shuts down after about 1.5-2 hours of usage on battery even though the battery indicator shows about 50% battery level before shutting down. I can confirm that at this point, the battery had drained completely because the laptop fails to boot without plugging in the charger. After plugging in the charger and restarting, the battery indicator does indeed show 0% (and starts charging normally upto 100%).
Can someone advice me about what the issue is and what can I do to ascertain whether the battery is faulty, or the charger, or my motherboard.

Hi Jennifer,
Thanks for the quick reply! Following are the details you requested.
The system runs fine when the charger is connected, both with and without battery. When battery is present, it gets charged to 100% (at least that is what the battery indicator says).

No, I don't have another battery of the same make. I have an old battery but it has worn out quite a bit. Its max capacity (in mWh) is almost 30% of the designed capacity. The battery I am currently using is a new one I bought last week (original Dell battery from "Dell" seller at Amazon.com)

Power related events in SystemLogs:
Let me know if you need the entire XML formatted details of the aforementioned log messages. I have sent you the service tag of my system via private message.

Hi,
Thank you for writing to us. While we look into the details of the system assist us with some more information.
*What happens when only the charger is connected to the system?
*Have you had the chance to connect any other battery to the system to check its performance?
*Also go to systemlogs and under power events check for system logs to see if any errors are listed.
Do send the service tag of the system via private message so that I can check the details and assist you further.
Regards,

The label on the new battery looks exactly like the one I had on my previous battery that came with the laptop. I purchased from here, which mentions Dell as the seller. Is there some concrete way I can verify if it is an original Dell battery apart from comparing labels?

Since you didn' t buy directly from Dell, it could be counterfeit. Compare the labels.

The posted price is way below what Dell would charge. You could ask your Dell contact to verify the information on the Battery. If is looks exactly like a genuine Dell it could be "reconditioned", where the cells are not replaced. A better low cost option is a third party replacements with a three year warranty. I have purchased several good ones on Amazon for $20-25."
