Dell Latitude E6520 Strange Charging
Hi, a friend gave me a Dell Latitude E6520 laptop and i have noticed that when i plug it into the charging port it does some weird things. i am not sure if this is normal but when i plug it into the port it starts charging then stops then starts again. when i put the laptop into sleep mode it stops charging then starts again and the same when i wake it up. i have a feeling it has something to do with the software in windows that allows it to charge faster but i am not sure. can someone please confirm if this is normal? the laptop charges perfectly fine but it is just different from other dell laptops.

Hi KRGMAN101,
Restart the system and press f2 on startup to enter BIOS - under Power Management - enable the ExpressCharge and check if the charging is normal. If not, read below:
Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point.
Update the BIOS and check - http://dell.to/2pWpCQW
If the adapter is not detected in BIOS or fits in loose, then test another adapter. If the other adapter also exhibits the same behavior, then replace the dc port - this is the part you need - http://bit.ly/2pRLNJF
You could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ
Also, please click my DELL-username and write me a private message with the service tag and your Name for case records.
Let us know if you have any other queries.

Hi KRGMAN101,
Thank you for the update.
This is the battery status when the system is on standby - kindly review the manual here for the led codes and behavior info - http://dell.to/2qtUZFO
Check if the other 2 leds have any specific pattern, which will help isolate the source of the issue.
If not, then try another battery / adapter and check if the behavior changes.
Let us know if you have any other queries.

Hi KRGMAN101,
Is there a specific pattern of blinking on the other 2 leds as well, 3 in total?
Would you able to shoot a video and upload it on YouTube and provide a link for us to review?
Let us know if you have any other queries.

Windows was running so the wireless light and hard drive light are the way they are.
but when the laptop is powered off the battery light blinks the same was as in the video without the hard drive and wireless light.

Hi KRGMAN101,
Thank you for the video.
Since the adapter is charging the battery fine, I would not suspect the charger or the dc port. There is no specific pattern for the battery light blinking. I suppose the battery itself might have a fault.
Kindly test another battery and check. If the other battery also exhibits the same behavior, then it could be another hardware component causing this issue and we can diagnose further if possible.
Let us know if you have any other queries.

i don't have a spare battery on hand right now but the tech at my school most likely has one. i will ask her if i can barrow one to see if the problem persists.

Hi KRGMAN101.
Maybe it was required that the battery start from a depleted charge. If the issue does not reoccur, I suppose the issue might be resolved. If it does, then test another battery and check as advised.

Hi KRGMAN101,
Were you able to test another battery?

Yes i did and it did not follow the battery. i tried a different charger but same thing. at this point i am not really going to worry about it because the laptop still operates perfectly fine while it does it so i don't know at this point.

Hi KRGMAN101,
Thank you for the update.
"it did not follow the battery" - are you referring that the replacement battery did not exhibit this behavior? If yes, then the original battery had the issue.
If the issue is unresolved and if you wish to pursue the case, please private message me the service tag and we shall research further.
Let us know if you have any other queries.

The battery is not the problem as I tried a different battery and it still did it. I even put the battery in a friend's laptop and it never did it. I even tried a different charger and did not solve it. At this point because it is not affecting anything I am not gonna worry about it. All that matters is that I can charge the laptop and use it.
